• How do digital certificates prove the identity of a device?

  - by StackedCrooked

  I understand how the relation between issuer and subject certificates enables verification of the subject's authenticity. If I connect to a networked device, and it sends me its certificate to identify itself, then I can verify that it was issued by a trusted party and that it has not been tampered with in any way. However, suppose I simply upload this certificate onto another device. Then what prevents me from having this device identify itself with the copied certificate?

• /etc/enviorment not being read into PATH variable

  - by Dan

  In Ubuntu the path variable is stored in /etc/enviorment. This is mine (I've made no changes to it, this is the system default): $ cat /etc/environment PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games" but when I examine my PATH variable: $ echo $PATH /home/dan/bin:/home/dan/bin:/bin:/usr/bin:/usr/local/bin:/usr/bin/X11 You'll notice /usr/games is missing (it was there up until a few days ago). My /etc/profile makes no mention of PATH. My ~/.profile is the default and only has: if [ -d "$HOME/bin" ] ; then PATH="$HOME/bin:$PATH" fi This only happens in gnome, not in tty1-6. This is missing from both gnome terminal and when I try to call applications from the applications dropdown. Anyone know what could be causing this? Thanks.

• what is the best mid/high-end class audio/music creation audio sound card?

  - by Chris

  Hello, I have a computershop myself, and I repair computers. But one of the things I really don't know (yet) is the performace od audio cards for music creation with midi. I have searched and searched and came up with some good reviews, but after browsing for a couple of hours I could't see the trees trough the forrest :-D (it's a dutch expression) At one moment I thought the M-Audio - Delta 1010LT would be a good PCIe card, later on I read that this card was released years ago. (but that could be false information) Also any personal expierence would be great, but not necessairy. I have searched a few cards, and I hope someone can help me make a choice for a friend of mine. He's buget is between $100 and $350 I know there are audio cards from $ 500 - $1850,- this is just too expensive.

• WinQual: Why would WER not accept code-signing certificates?

  - by Ian Boyd

  In 2005 i tried to establish a WinQual account with Microsoft, so i could pick up our (if any) crash dump files submitted automatically through Windows Error Reporting (WER). i was not allowed to have my crash dumps, because i don't have a Verisign certificate. Instead i have a cheaper one, generated by a Verisign subsidiary: Thawte. The method in which you join is: you digitally sign a sample exe they provide. This proves that you are the same signer that signed apps that they got crash dumps from in the wild. Cryptographically, the private key is needed to generate a digital signature on an executable. Only the holder of that private key can create a signature with for the matching public key. It doesn't matter who generated that private key. That includes certificates that are generated from: self-signing Wells Fargo DigiCert SecureTrust Trustware QuoVadis GoDaddy Entrust Cybertrust GeoTrust GlobalSign Comodo Thawte Verisign Yet Microsof's WinQual only accepts digital certificates generated by Verisign. Not even Verisign's subsidiaries are good enough (Thawte). Can anyone think of any technical, legal or ethical reason why Microsoft doesn't want to accept code-signing certificates? The WinQual site says: Why Is a Digital Certificate Required for Winqual Membership? A digital certificate helps protect your company from individuals who seek to impersonate members of your staff or who would otherwise commit acts of fraud against your company. Using a digital certificate enables proof of an identity for a user or an organization. Is somehow a Thawte digital certificate not secure? Two years later, i sent a reminder notice to WinQual that i've been waiting to be able to get at my crash dumps. The response from WinQual team was: Hello, Thanks for the reminder. We have notified the appropriate people that this is still a request. In 2008 i asked this question in a Microsoft support forum, and the response was: We are only setup to accept VeriSign Certificates at this point. We have not had an overwhelming demand to support other types of certificates. What can it possibly mean to not be "setup" to accept other kinds of certificates? If the thumbprint of the key that signed the WinQual.exe test app is the same as the thumbprint that signed the executable who's crash dump you got in the wild: it is proven - they are my crash dumps, give them to me. And it's not like there's a special API to check if a Verisign digital signature is valid, as opposed to all other digital signatures. A valid signature is valid no matter who generated the key. Microsoft is free to not trust the signer, but that's not the same as identity. So that is my question, can anyone think of any practical reason why WinQual isn't setup to support digital signatures? One person theorized that the answer is that they're just lazy: Not that I know but I would assume that the team running the winQual system is a live team and not a dev team - as in, personality and skillset geared towards maintenance of existing systems. I could be wrong though. They don't want to do work to change it. But can anyone think of anything that would need to be changed? It's the same logic no matter what generated the key: "does the thumbprint match". What am i missing?

• Oracle WebCenter - Well Connected

For those of you who don’t know Dan, he is one of the major forces in the content management industry. He founded eVisory and IMERGE Consulting, he is an AIIM Fellow and a former US Technical Expert to the International Standards Organization (ISO), and has been a driving force behind EmTag, AIIM’s Emerging Technologies Group. His post is interesting – it starts out talking about our Moveoff Documentum campaign, but then it becomes a much deeper insight into the ECM industry. Dan points out that Oracle has been making quiet strides in the ECM industry. In fact, analysts share this view Oracle, pointing out Oracle is growing greater than 20% annually while many of the big vendors are shrinking. And as Dan points out, this cements Oracle as one of the big five in the ECM space – the same week that Autonomy was removed from the Gartner Magic Quadrant for ECM. One of the key things points out is that Oracle WebCenter is well connected. WebCenter has out-of-the-box connections to key enterprise applications such as E-Business Suite, PeopleSoft, Siebel and JD Edwards. Those out-of-the-box integrations make it easy for organizations to drive content right into the places where it is needed, in the midst of business processes. At the same time, WebCenter provides composite interface capabilities to bring together two or more of these enterprise applications onto the same screen. Combine that with the capabilities of Oracle Social Network, you start to see how Oracle is providing a full platform for user engagement. But beyond those connections, WebCenter can also connect to other content management systems. It can index and search those systems from a single point of search, bringing back results in a single combined hitlist. WebCenter can also extend records management capabilities into Documentum, SharePoint, and email archiving systems. From a single console, records managers can define a series, set a retention schedule, and place holds – without having to go to each system to make these updates. Dan points out that there are some new competitive dynamics – to be sure. And it is interesting when a system can interact with another system, enforce dispositions and holds, and enable users to search and retrieve content. Oracle WebCenter is providing the infrastructure to build on, and the interfaces to drive user engagement. It’s an interesting time.

• USB Drive Warm Boot Issue. Cold boot = Perfect. Warm boot = "No boot sector found on USB device"

  - by Dan

  I'm experiencing a boot/reboot quirk similar to, yet somewhat different from others posted here. I have two Western Digital "Passport" external USB2 drives (160GB and 320GB) with Ubuntu 11.10 installed. The BIOS on my laptop is set to boot USB drives before the internal drive, and it works well. Either drive will cold-boot Ubuntu 11.10 perfectly. However, at times the computer must be restarted (warm boot) to have software updates or other changes take effect. When I warm-boot the computer, the computer goes through its normal shutdown/restart, then the usual BIOS tests, at which time the USB drive is selected momentarily (as normal), and that's when the trouble starts. I get a "No boot sector found on USB device", and the computer proceeds to boot Windows from the internal drive. If I press F12 early during the restart sequence (allows manual selection of the boot sequence), USB is still shown before the internal drive on the sequence list (as it should be). If I highlight "USB" and press ENTER, I still get a "No boot sector..." error message, but the external USB drive then proceeds to boot Ubuntu normally. I have a third external USB drive (Western Digital 160 GB Media Center) that cold-boots and warm-boots perfectly, so I know everything in the computer is set up properly. It also tells me Ubuntu is set up correctly on the drives, as all three drives were done identically, and at the same time. I've tried formatting the Passport drives NTFS and FAT32, but it didn't change anything. If I power-down the computer, then start it up again, it will boot Ubuntu from either of the Passport drives perfectly - every time. It's as if during a warm boot the Passport drives are somehow looking for the boot loader in the wrong location on the drive - yet either drives works when booting from a cold start. Not a show-stopper .. but frustrating. Computer is a Dell XPS M1530, A12 BIOS (latest), but I don't think the computer plays into the issue because one of the three drives works at all times. It's only the two WD Passport models at issue here. Thanks!

• .com domain transfer failing

  - by digital

  Hi, I'm trying to transfer one of my .com addresses between registrars. I'm down as the owner contact (confirmed working) and the losing registrar is down as the tech and admin contact. Last week I received an email stating that the domain transfer had been rejected by the losing registrar. I contacted the losing registrar and they denied that. My money from the winning registrar was refunded and I was told to try again. I've initiated the transfer again and received confirmation of pending transfer, I gave the correct EPP code and confirmed the transfer. Currently the status on the domain is set as OK, should it not be transfer pending? According to my name.com transfer page if the transfer is not authd in 5 days it will auto transfer anyway. I don't believe this will happen. Name.com have been really helpful but they can't really do much more now. The losing registrar is not being helpful hence me turning here. What can I do to make sure the domain transfers? The domain transfer is set to expire on the 17th. Any help would be greatly appreciated.

• Windows 7 restarts PC when selected from GRUB Menu

  - by Dan Still

  I installed windows 7 on a RAID 5 (2@160GB SATA +1@160GB SATA for RAID 5) I then proceeded to install Ubuntu 11.10 using the Live CD and opted: "Install along side Windows 7 Option" Upon boot GRUB appears normally and I can select and run Ubuntu with no difficulties. When I select Windows 7 from GRUB the PC restarts and consequently goes back to GRUB. I have attempted to use the Windows 7 DVD to repair the installation but to no avail. The Wizard ran twice as it described it might, after the second attempt came back with an '...inability to repair...' error. I am sure there is an answer to this somewhere but I have yet to be able to find it. (2 weeks and countless attempts and searches before posting this question. Although I am happy to use Ubuntu alone my wife likes to watch Netflix and therein requires the Windows 7 installation. Any answers are appreciated and welcomed. Thanks in advance. Dan Still

• FairScheduling Conventions in Hadoop

  - by dan.mcclary

  While scheduling and resource allocation control has been present in Hadoop since 0.20, a lot of people haven't discovered or utilized it in their initial investigations of the Hadoop ecosystem. We could chalk this up to many things: Organizations are still determining what their dataflow and analysis workloads will comprise Small deployments under tests aren't likely to show the signs of strains that would send someone looking for resource allocation options The default scheduling options -- the FairScheduler and the CapacityScheduler -- are not placed in the most prominent position within the Hadoop documentation. However, for production deployments, it's wise to start with at least the foundations of scheduling in place so that you can tune the cluster as workloads emerge. To do that, we have to ask ourselves something about what the off-the-rack scheduling options are. We have some choices: The FairScheduler, which will work to ensure resource allocations are enforced on a per-job basis. The CapacityScheduler, which will ensure resource allocations are enforced on a per-queue basis. Writing your own implementation of the abstract class org.apache.hadoop.mapred.job.TaskScheduler is an option, but usually overkill. If you're going to have several concurrent users and leverage the more interactive aspects of the Hadoop environment (e.g. Pig and Hive scripting), the FairScheduler is definitely the way to go. In particular, we can do user-specific pools so that default users get their fair share, and specific users are given the resources their workloads require. To enable fair scheduling, we're going to need to do a couple of things. First, we need to tell the JobTracker that we want to use scheduling and where we're going to be defining our allocations. We do this by adding the following to the mapred-site.xml file in HADOOP_HOME/conf: <property> <name>mapred.jobtracker.taskScheduler</name> <value>org.apache.hadoop.mapred.FairScheduler</value> </property> <property> <name>mapred.fairscheduler.allocation.file</name> <value>/path/to/allocations.xml</value> </property> <property> <name>mapred.fairscheduler.poolnameproperty</name> <value>pool.name</value> </property> <property> <name>pool.name</name> <value>${user.name}</name> </property> What we've done here is simply tell the JobTracker that we'd like to task scheduling to use the FairScheduler class rather than a single FIFO queue. Moreover, we're going to be defining our resource pools and allocations in a file called allocations.xml For reference, the allocation file is read every 15s or so, which allows for tuning allocations without having to take down the JobTracker. Our allocation file is now going to look a little like this <?xml version="1.0"?> <allocations> <pool name="dan"> <minMaps>5</minMaps> <minReduces>5</minReduces> <maxMaps>25</maxMaps> <maxReduces>25</maxReduces> <minSharePreemptionTimeout>300</minSharePreemptionTimeout> </pool> <mapreduce.job.user.name="dan"> <maxRunningJobs>6</maxRunningJobs> </user> <userMaxJobsDefault>3</userMaxJobsDefault> <fairSharePreemptionTimeout>600</fairSharePreemptionTimeout> </allocations> In this case, I've explicitly set my username to have upper and lower bounds on the maps and reduces, and allotted myself double the number of running jobs. Now, if I run hive or pig jobs from either the console or via the Hue web interface, I'll be treated "fairly" by the JobTracker. There's a lot more tweaking that can be done to the allocations file, so it's best to dig down into the description and start trying out allocations that might fit your workload.

• Display problem with fresh install of 12.04

  - by Dan

  Just intalled Ubuntu 12.04 from CD and install went with no problems. After rebooting, I get the initial purple screen and then a black screen with mouse pointer and a few stray pixels at the bottom left of screen. Occasionally during the boot process, the purple screen comes back momentarily but then back to the black screen with the mouse pointer. When I finally give up and press the power button, the purple screen returns with the Shut Down box visible as it is shutting down. Any ideas? I have tried adding nomodeset after quiet splash, but no change. Possibly not doing it correctly, since I am somewhat of a newbie to linux. Thanks! Dan

• Google webmaster tools: parameters that only apply on one page

  - by Imagine digital

  I'm trying to get my e-commerce website on google and still figuring out how it all works. Now, I have seen this feature named URL-parameters, allowing me to set different parameters that affect page content to be indexed (one can also set parameters that do not affect the page, but for me that does not apply..). The question I have about this is whether and how I should add parameters that I only have on some pages of my site. example: The homepage of my site is www.mysite.nl. no parameters at all. But when a user clicks the navigation bar, it links to www.mysite.nl/itemList.php?category=&....subCategory=.... The parameters category and subCategory define whether there is content on my itemList page and what content that is. It gets matching products out of my database based on those 2 variables. The question: How do I make sure that I apply the google URL Parameters function decently for my website?

• Dutch for once: op zoek naar een nieuwe uitdaging!

  - by Dennis Vroegop

  Originally posted on: http://geekswithblogs.net/dvroegop/archive/2013/10/11/dutch-for-once-op-zoek-naar-een-nieuwe-uitdaging.aspxI apologize to my non-dutch speaking readers: this post is about me looking for a new job and since I am based in the Netherlands I will do this in Dutch… Next time I will be technical (and thus in English) again! Het leuke van interim zijn is dat een klus een keer afloopt. Ik heb heel bewust gekozen voor het leven als freelancer: ik wil graag heel veel verschillende mensen en organisaties leren kennen. Dit werk is daar bij uitstek geschikt voor! Immers: bij iedere klus breng ik niet alleen nieuwe ideeën en kennis maar ik leer zelf ook iedere keer ontzettend veel. Die kennis kan ik dan weer gebruiken bij een vervolgklus en op die manier verspreid ik die kennis onder de bedrijven in Nederland. En er is niets leukers dan zien dat wat ik meebreng een organisatie naar een ander niveau brengt! Iedere keer een ander bedrijf zoeken houdt in dat ik iedere keer weg moet gaan bij een organisatie. Het lastige daarvan is het juiste moment te vinden. Van buitenaf gezien is dat lastig in te schatten: wanneer kan ik niets vernieuwends meer bijdragen en is het tijd om verder te gaan? Wanneer is het tijd om te zeggen dat de organisatie alles weet wat ik ze kan bijbrengen? In mijn huidige klus is dat moment nu aangebroken. In de afgelopen elf maanden heb ik dit bedrijf zien veranderen van een kleine maar enthousiaste groep ontwikkelaars naar een professionele organisatie met ruim twee keer zo veel ontwikkelaars. Dat veranderingsproces is erg leerzaam geweest en ik ben dan ook erg blij dat ik die verandering heb kunnen en mogen begeleiden. Van drie teams met ieder vijf of zes ontwikkelaars naar zes teams met zeven tot acht ontwikkelaars per team groeien betekent dat je je ontwikkelproces heel anders moet insteken. Ook houdt dat in dat je je teams anders moet indelen, dat de organisatie zelf anders gemodelleerd moet worden en dat mensen anders met elkaar om moeten gaan. Om dat voor elkaar te krijgen is er door iedereen heel hard gewerkt, is er een aantal fouten gemaakt, is heel veel van die fouten geleerd en is uiteindelijk een vrijwel nieuw bedrijf ontstaan. Het is tijd om dit bedrijf te verlaten. Ik ben benieuwd waar ik hierna terecht kom: ik ben aan het rondkijken naar mogelijkheden. Ik weet wèl: het bedrijf waar ik naar op zoek ben, is een bedrijf dat openstaat voor veranderingen. Veranderingen, maar dan wel met het oog voor het individu; mensen staan immers centraal in de software ontwikkeling! Ik heb er in ieder geval weer zin in!

• NRF Big Show 2011 -- Part 2

  - by David Dorf

  One of the things I love about attending NRF is visiting the smaller booths to see what new innovative ideas have sprung up. After all, by watching emerging technologies we can get a sense of how the retail experience might change. After NRF I'm hoping to write a post on what I found, if anything, so be sure to check back. At the Oracle Retail booth we'll be demonstrating some of the aspects of the changing retail experience. These demos use a mix of GA and experimental components. Here are some highlights: 1. Checkin We wrote a consumer iPhone app we call Store Gateway that lets consumers access information from the store. They'll start by doing a checkin when they arrive that will alert the store manager via another iPhone app we wrote called Mobile Manager. Additionally, we display a welcome messaging using Starmount's digital sign. 2. Receive Offers There are three interaction points where a store can easily make an offer to a consumer: checkin, product scans, and checkout. For this demo we're calling our Universal Offer Engine at checkin to determine the best offer for this particular consumer. This offer is then displayed on the consumer's phone as well as on the digital sign. 3. Scan Products To thwart consumers from scanning product barcodes, we used Store Inventory Management to print QRCodes on shelf label then provided access to a scanner in the Store Gateway iphone app. When the consumer scans the shelf label they are shown product information provided by the retailer. 4. Checkout While we don't have a NFC-enabled mobile phone, we have a NFC chip that can attach to a phone. We're using this to checkout using a reader provided by ViVOTech. Tap the phone on the reader, and the POS accesses the customer#, coupons, and payment information. This really speeds the checkout process. 5. Digital Receipt After the transaction is complete, a digital copy of the receipt is sent to Intuit's QuickReceipts where consumers to store all their digital receipts. There's even an iPhone app that provides easy access to the receipts. This covers about half of what what we'll be showing, so be sure to stop by. I'll also be talking about how mobile is impacting the retail experience at the Wednesday morning session NRF Mobile Retail Initiative: a Blueprint for Action. See you at the Big Show!

• TDC: The Developer's Conference Day One

  - by Tori Wieldt

  The Developer's Conference (TDC) kicked off Wednesday in São Paulo, Brazil. With over 3000 developers in attendance over five days, it is the premier multi-community developer conference in Brazil, organized by Globalcode. Yara Senger, one of the organizers said, "We like to say multi-community rather than multi-technology because it is interesting and benefical when various communities get together. They learn so much from each other!" TDC includes tracks on Java and several other technologies, including SOA, Python, Ruby, mobile and digital TV. In the mobile track, developers who create a Java ME app will get a Nokia S40 phone!New this year at TDC is the Java University track, sponsored by Oracle.  It is aimed at university students and professionals who are new to Java. The lectures are introductory level, with an educational focus and practical exercises. The Java track and other tracks, such as SOA, mobile and Digital TV, are getting lots of help from the expertise of Brazilian JUGS members. Thanks to GoJava, JavaBahia, JavaNoroeste and SouJava!Carlos Fernando, one of the coordinators on the Digital TV track, said "My goal is to teach developers the basics of digital TV, and show them the tools used to build interactive TV applications." Fernando explained the concept of "the second screen:" that many people watch TV and have second smart device (tablet or smartphone) with them, and this creates many opportunities for developers. For example, while watching TV, a viewer can get extra content (interviews, behind the scenes) on their tablet. More interestingly, while watching their favorite TV show a viewer likes an outfit one of the actors is wearing, their smartphone can tell them where they can buy it nearby, or they can order it online immediately. Fernando exclaimed, "The opportunities for developers are nearly infinite in the area of digital TV!" At the TDC opening keynote, Debora Palermo, Oracle University country manager for Brazil, reminded attendees that Java is present in many devices, from simple to complex, and knowledge of this platform can open many doors in the labor market. She explained Oracle's Workforce Development Program (WDP), managed by Oracle University, which allows educational institutions to deliver Oracle training. WDP allows for easy and low-cost access to Oracle training in local communities across the world. "Oracle University is committed to creating the next generation of Java developers, and WDP can make that happen," Palermo said. As of March 2012, Oracle University is partnering with Globalcode to offer WDP. Students can earn official Oracle Course Certifications, a great way to learn Java.Brazilian developers that cannot attend TDC can watch live streaming.

• confusion about installing/using git; how to undo

  - by dan

  I'm very new to ubuntu so I'm sure this is a dumb question. I wanted to install some source code that was on git. Don't really know what that means, I've never used git before, but I figured it was time to learn so I first installed git. Next I tried to clone the git directory of the software I want to install. I got a message saying "the authenticity of IP:IP:IP:IP can't be established". I went ahead and ended up with another message saying warning such and such will be added to known hosts. I went ahead and it said something about hanging up on the connection. After searching the internet for awhile I realized I didn't need git to install the software but now I have it installed and have added some host to some file or another. I'm concerned I've created some security issues I need to fix. I know this is stupid but can anyone help me undo what I've done, or better understand what I've done. Did adding a git project open up my system? Beyond that can anyone tell me how git works. Everything I've found assumes I know stuff that I don't yet. Thanks. Dan

• PC BluRay - Multichannel HD Audio output

  - by sheepsimulator

  When playing a BluRay movie on a PC (any OS, Mac/Win/Linux), I have some questions about audio output: When playing a BluRay disc on the PC using a BluRay player program, can it decode the multichannel (7.1) LPCM/ Dolby Digital Plus / Dolby TrueHD / DTS-HD / DTS-HDMA soundtracks in their HD formats (ie, without downmixing to Dolby Digital or DTS or PCM) and output the audio directly to the soundcard's 7.1 line-level analog outputs? Is it possible to bitstream the the multichannel (7.1) LPCM/ Dolby Digital Plus / Dolby TrueHD / DTS-HD / DTS-HDMA soundtracks in their HD formats (ie, without downmixing to Dolby Digital or DTS or PCM) over the HDMI output to a receiver when using a BluRay player program? I'd kinda like to know. I'm contemplating building a home theater PC, and the above functionality is important. I'd prefer that #1 is possible, actually, because it would mean I wouldn't have to buy a receiver.

• Making sense of S.M.A.R.T

  - by James

  First of all, I think everyone knows that hard drives fail a lot more than the manufacturers would like to admit. Google did a study that indicates that certain raw data attributes that the S.M.A.R.T status of hard drives reports can have a strong correlation with the future failure of the drive. We find, for example, that after their first scan error, drives are 39 times more likely to fail within 60 days than drives with no such errors. First errors in re- allocations, offline reallocations, and probational counts are also strongly correlated to higher failure probabil- ities. Despite those strong correlations, we find that failure prediction models based on SMART parameters alone are likely to be severely limited in their prediction accuracy, given that a large fraction of our failed drives have shown no SMART error signals whatsoever. Seagate seems like it is trying to obscure this information about their drives by claiming that only their software can accurately determine the accurate status of their drive and by the way their software will not tell you the raw data values for the S.M.A.R.T attributes. Western digital has made no such claim to my knowledge but their status reporting tool does not appear to report raw data values either. I've been using HDtune and smartctl from smartmontools in order to gather the raw data values for each attribute. I've found that indeed... I am comparing apples to oranges when it comes to certain attributes. I've found for example that most Seagate drives will report that they have many millions of read errors while western digital 99% of the time shows 0 for read errors. I've also found that Seagate will report many millions of seek errors while Western Digital always seems to report 0. Now for my question. How do I normalize this data? Is Seagate producing millions of errors while Western digital is producing none? Wikipedia's article on S.M.A.R.T status says that manufacturers have different ways of reporting this data. Here is my hypothesis: I think I found a way to normalize (is that the right term?) the data. Seagate drives have an additional attribute that Western Digital drives do not have (Hardware ECC Recovered). When you subtract the Read error count from the ECC Recovered count, you'll probably end up with 0. This seems to be equivalent to Western Digitals reported "Read Error" count. This means that Western Digital only reports read errors that it cannot correct while Seagate counts up all read errors and tells you how many of those it was able to fix. I had a Seagate drive where the ECC Recovered count was less than the Read error count and I noticed that many of my files were becoming corrupt. This is how I came up with my hypothesis. The millions of seek errors that Seagate produces are still a mystery to me. Please confirm or correct my hypothesis if you have additional information. Here is the smart status of my western digital drive just so you can see what I'm talking about: james@ubuntu:~$ sudo smartctl -a /dev/sda smartctl version 5.38 [x86_64-unknown-linux-gnu] Copyright (C) 2002-8 Bruce Allen Home page is http://smartmontools.sourceforge.net/ === START OF INFORMATION SECTION === Device Model: WDC WD1001FALS-00E3A0 Serial Number: WD-WCATR0258512 Firmware Version: 05.01D05 User Capacity: 1,000,204,886,016 bytes Device is: Not in smartctl database [for details use: -P showall] ATA Version is: 8 ATA Standard is: Exact ATA specification draft version not indicated Local Time is: Thu Jun 10 19:52:28 2010 PDT SMART support is: Available - device has SMART capability.
