• Are generic keywords in url bad for SEO? [closed]

  - by user1661479

  Possible Duplicate: Squeezing all the SEO out of a URL as possible Need help with url structure. Let's say I'm a manufacturer of Wire EDM machines. Is it bad for me to put the keywords wire-edm in my url to help try to raise SEO ranking? For example: mywebsite.com/wire-edm/machine/model-xxxx mywebsite.com/wire-edm/customer-service mywebsite.com/wire-edm/contact Or should I leave it as the following because the gains are fairly insignificant and it doesn't help users understand my site structure: mywebsite.com/machine/model-xxxx mywebsite.com/customer-service mywebsite.com/contact I’d like to hear what everyones thoughts are on this and please provide some sources for which method is better.

• Checking a record is due based on the 'occuring' field

  - by andy

  I have records that have dates against them and an occurring field that contains none,yearly and monthly id status note date last_updated occurring 1 open --- 01/01/2011 01/02/2010 yearly 2 open --- 05/05/2011 03/05/2011 monthly 3 open --- 06/06/2011 05/06/2011 none Now I need to be able to check if a record is due (the date set has passed) which works perfect if occurring is set to none but I'm unsure of how to approach it when it's set to yearly or monthly (IE: This day in the year/month has passed) So with the above records, if I had a method on the record called due? providing the status is 'open' it needs to return true every year when it's passed that date if it's not been updated within the year yet. I apologise if this is confusing but it's melting my brain just trying to think of it, let alone put it into words.

• Installed 11.10 on shared drive, when other partition mounted, HDD shown full

  - by Thebetpet

  I just partitioned a 500GB HDD 50%-50%. I installed ubuntu 11.10 on one half and copied a load of files onto the other. When I don't mount the other partition, it shows I have used 12.1GB and have about 240GB free. The second I mount the other partition, I can't copy any files over and get a disk full message. There is about 10-20GB Free on the other partition. Am I doing something wrong or is this a bug?

• How can I use Ubuntu to rescue files from an NTFS drive?

  - by dago

  I reinstalled windows on the laptop of my daughter. Before doing this we made a copy of her music, pictures and so on. Unfortunately, the folder we created for the backup was empty (I checked after I reinstalled windows). Today a miracle happened, as suddenly the data were back but when Itried to copy them to another place thez disappeared again. Checking the drive with disk utility I got the message "filesystem is not clean". Is there a way to recover the data? Preferred solution would be a tool with a gui. The drive I need to repair is formatted in NTFS and is connected via usb to laptop.

• ImgBurn fails to burn data CD-R disk due to "Layouts do not match" error

  - by 0xAether

  I have a reoccurring problem with the program ImgBurn. Whenever I try and burn anything to a CD-R using ImgBurn it burns just fine, except for when I go and verify the disk. It tells me that the "Layouts do not match". Windows 7 shows the disk as completely blank. Although, I see on the bottom of the disk it has been written to. I can burn ISO files to DVD-R's just fine. This only seems to happen with CD-R's. The CD-R's I'm using are Memorex Cool Colors 52x CD-R's. I have looked on Google, and it seems like I'm not the only one this happens to. Unfortunately, no one is able to provide an explanation. I have included the log file from the last CD I just burnt. If you need anything else to better diagnose this problem, I will gladly provide it. ; //****************************************\\ ; ImgBurn Version 2.5.7.0 - Log ; Monday, 19 November 2012, 16:11:57 ; \\****************************************// ; ; I 16:04:55 ImgBurn Version 2.5.7.0 started!

• Slow disk transfer rate

  - by Nooklez

  I have problem with slow disk transfer rate. It's static files server for our website. I was making backup of data and noticed that tar is very slow. So I did hdparm -t and... hdparm -t /dev/sda3 /dev/sda3: Timing buffered disk reads: 6 MB in 4.70 seconds = 1.28 MB/sec It's low traffic hour now on our site, so huge I/O traffic is not a reason (iotop show less than 1 MB/s).

• Make exact mp4 (H264) format for uploading to youtube

  - by WHITECOLOR

  With ffmpeg I'm converting video from mp3 and picture to upload it to youtube. After upload, conversion fails. Reasons are unknown. I believe the problem is in format. By the way If I'm uploading file 5 minutes length, it fails if I upload 30 seconds of this file it succeeds. I have donwload mp4 file from youtube. Then I uploaded it, it is done very fast. So a nice solution would be to convert videos to the same format that is done by google.

• Vista 64-bit, DISK BOOT FAILURE

  - by weka

  So I have this Acer Aspire AX3200-U3600A with Windows Vista (64-bit). Every night I turn it off and turn it back on in the morning. Around three weeks ago, I did a fresh factory reimage. Good as new. Then around two days ago, when I turned it on, I noticed it was running extremly slow. As in, it would often freeze up while I had multiple applications open when it usually never froze up. So I decided to restart my computer. Big mistake. My computer froze right after I clicked shut-down. I waited a while. Nothing. Waited some minutes. Nope. I decided to shut it down by pressing the power button. Here is where the problems begin. When I turned it back on, I saw the Windows logo and loading bar and then it loaded to black. I turned it off again forcefully by power button and then once more... then I got: AMD Data Change... Update New Data to DMI! then later the screen clears and I get: AHCI Option ROM BIOS Revision: 01.05.92 Date: 02-19-2008 Copyright (c) 2006-2008 Phoenix Technologies, LTD Port 01: Reset Port Error!! Port 02: then the screen clears again but this time, this loads from the bottom: Nvidia Boot Agent 249.0542 (copyright stuff... blah blah) PXE-E61: Media test failure, check cable. PXE-M0F: Exiting Nvidia Boot Agent DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER. So I try to go into Safe Mode. Well, first of all it doesn't load as fast. After it loads disk.sys from windows/drivers, it will wait a while (2-3 mins) THEN load. However it loads the Acer eRecovery Management Tool. I have three options: Reset computer to factory default, Restore computer from user's backup, or Exit. However, the top two options are gray and disabled where as the Exit is in blue and definitely clickable. So obviously safe mode is not there... A strong thing to note: In the beginning when all of this started, I did a Boot Windows Normal from pressing f8 and I got to my desktop! It logged me in. I could see the icons on my files. However my desktop was extremely slow as in when I clicked on the Start menu, it would wait a while, then load up the menu with JUST the gradient, no text or icons... so as you can see... it saw my HDD? Also, before anyone says, I have NO USB plugged in. My mouse and keyboard are not USB inputs, I assure you. And this came without a recovery CD AND when I went in BIOS, to change the BOOT ORDER, I did NOT see a CD-ROM option. And when I tried pressing ALT+F10 to get into Acer eRecovery Management, the top two options were disabled as well. But sometimes on start-up, I get: Windows has encountered a problem communicating with a device connected to your computer. This error can be caused by unplugging a removable storage device such as an external USB drive while the device is in use, or by faulty hardware such as a hard drive or CD-ROM drive that is failing. Make sure any removeable storage is properly connected and then restart your computer. If you continue to receive this error message, contact the hardware manufacturer. Status: 0xc00000e9 Info: An unexpected I/O error has occured. Then I tried Last Known Good Configuration Settings, that gives me a BSOD. What should I do/

• How to export SQL Server data from corrupted database (with disk write error)

  - by damitamit

  IT realised there was a disk write error on our production SQL Server 2005 and hence was causing the backups to fail. By the time they had realised this the nightly backup was old, so were not able to just restore the backup on another server. The database is still running and being used constantly. However DBCC CheckDB fails. Also the SQL Server backup task fails, Copy Database fails, Export Data Wizard fails. However it seems all the data can be read from the tables (i.e using bcp etc) Another observation I have made is that the Transaction Log is nearly double the size of the Database. (Does that mean all the changes arent being written to the MDF?) What would be the best plan of attack to get the database to a state where backups are working and the data is safe? Take the database offline and use the MDF/LDF to somehow create the database on another sql server? Export the data from the database using bcp. Create the database (use the Generate Scripts function on the corrupt db to create the schema on the new db) on another sql server and use bcp again to import the data. Some other option that is the right course of action in this situation? The IT manager says the data is safe as if the server fails, the data can be restored from the mdf/ldf. I'm not sure so insisted that we start exporting the data each night as a failsafe (using bcp for example). IT are also having issues on the hardware side of things as supposedly the disk error in on a virtualized disk and can't be rebuilt like a normal raid array (or something like that). Please excuse my use of incorrect terminology and incorrect assumptions on how Sql Server operates. I'm the application developer and have been called to help (as it seems IT know less about SQL Server than I do). Many Thanks, Amit Results of DBBC CheckDB: Msg 1823, Level 16, State 2, Line 1 A database snapshot cannot be created because it failed to start. Msg 7928, Level 16, State 1, Line 1 The database snapshot for online checks could not be created. Either the reason is given in a previous error or one of the underlying volumes does not support sparse files or alternate streams. Attempting to get exclusive access to run checks offline. Msg 5030, Level 16, State 12, Line 1 The database could not be exclusively locked to perform the operation. Msg 7926, Level 16, State 1, Line 1 Check statement aborted. The database could not be checked as a database snapshot could not be created and the database or table could not be locked. See Books Online for details of when this behavior is expected and what workarounds exist. Also see previous errors for more details. Msg 823, Level 24, State 3, Line 1 The operating system returned error 1(error not found) to SQL Server during a write at offset 0x00000674706000 in file 'G:\AX40_Dynamics_Live.mdf'. Additional messages in the SQL Server error log and system event log may provide more detail. This is a severe system-level error condition that threatens database integrity and must be corrected immediately. Complete a full database consistency check (DBCC CHECKDB). This error can be caused by many factors; for more information, see SQL Server Books Online.

• Why does newline come before space in the output of hexdump?

  - by ??????? ???????????

  Printing these characters in the "Canonical" format gives the output that I expect, while the default format throws me off. $ echo " " |hexdump # Reversed? 0000000 0a20 0000002 $ echo -n " " |hexdump # Ok, fair enough. 0000000 0020 $ echo " " |hexdump -C # Canonical 00000000 20 0a | .| 00000002 With a different string, such as "123" the output is even more confusing: $ echo "123" |hexdump 0000000 3231 0a33 0000004 The output here does not seem "reversed", but rather shuffled. Would anyone care to explain (briefly) what is going on here?

Esp these days i was testing the write-read speed of ssd, which I was always caring.... however result turned out not good as I expected, or even worse Three kinds of read-write were implemented in my test 1. read and write directly from and into ssd, with openning ssd as a whole device. in windows: _open("\\:g", ***).. It can be very tricky and hairy that you'd write a data with size of folds of 512, at the disk position of folds of 512bytes... So, If you wanto write just a byte or 4 bytes, you'v to write at least a whole sector one time. 2. Read and write data from and into files located in SSD... 3. Read and Write data from and into files in mechanical Disk I compared the pratices below...I found ssd sucks...the ssd performs worse than mechanical disk... so i am wondering where i can get the potential performance of ssd, since ssd is said to a substitute for mechanical disk in the future.. Nevertheless, I test ssd with a pro-hard-disk tools..ssd is like twice speedier than mechanical disk. So, why? Thanx very much...If you know tips of ssd...follow me

• Invalid keystore format with SSL in Tomcat 6

  - by strauberry

  I'm trying to setup SSL in my local Tomcat 6 installation. For this, I followed the official How-To doing the following: $JAVA_HOME/bin/keytool -genkey -v -keyalg RSA -alias tomcat -keypass changeit -storepass changeit $JAVA_HOME/bin/keytool -export -alias tomcat -storepass changeit -file /root/server.crt Then changing the $CATALINA_BASE/conf/server.xml, in-commenting this: <Connector port="8443" protocol="HTTP/1.1" SSLEnabled="true" maxThreads="150" scheme="https" secure="true" clientAuth="false" sslProtocol="TLS" keystoreFile="/root/.keystore" keystorePass="changeit" /> After starting Tomcat, I get this Exception: INFO: Initializing Coyote HTTP/1.1 on http-8080 30.06.2011 10:15:24 org.apache.tomcat.util.net.jsse.JSSESocketFactory getStore SCHWERWIEGEND: Failed to load keystore type JKS with path /root/.keystore due to Invalid keystore format java.io.IOException: Invalid keystore format at sun.security.provider.JavaKeyStore.engineLoad(JavaKeyStore.java:633) at sun.security.provider.JavaKeyStore$JKS.engineLoad(JavaKeyStore.java:38) at java.security.KeyStore.load(KeyStore.java:1185) When I look into the keystore with keytool -list I get root@host:~# $JAVA_HOME/bin/keytool -list Enter key store password: changeit Key store type: gkr Key store provider: GNU-CRYPTO Key store contains 1 entry(ies) Alias name: tomcat Creation timestamp: Donnerstag, 30.

Thank you!

• Filesystems for webserver with SATA and Solid State disk,

  - by Jorisslob

  We have just ordered a new webserver with 120 Gb solid state disk and a SATA disk. I am trying to plan ahead what sort of filesystem to use. This system will be running Linux, Apache/Tomcat to host java services. The main service is a system where people can upload reasonably large files (in the order of 100 Mb, images, image stacks and video), which people will be able to annotate and which will be sent to a database server when annotation is complete. Thus far, I plan to put most of the utility programs of the operating system om the SSD and put the large media files there. The SATA disks will hold the less volitile data like apache, tomcat and the servlets. For filesystems I have considered going for the stable EXT3 because I hear that it is best supported. The downside seems to be that it not the ideal choice for large files. That is why I am leaning towards using XFS for the SSD and EXT3 for the SATA. My questions are: 1) Does this sound like a reasonable setup? 2) What filesystems would you recommend for the SSD and for the SATA? Thanks

• Unconvert Text File from Binary Format

  - by Hammer Bro.

  I've got a rather large CSV file (~700MB) which I know to consist of lines of 27-character alpha-numeric hashes; no commas or anything fancy. Somehow, during its migration from Windows to Linux (via winSCP and then a few regular SCPs), it has converted into some kind of binary format I am unfamiliar with. If I open the file in vi, everything appears fine, and it says [converted] at the bottom, although I know it's not a line endings issue (and dos2unix doesn't help). If I 'head' the file, it looks proper except for a "ÿþ" at the beginning of the first line. If I open up the file in nano, however, I see the "ÿþ" at the start and then "^@" before every character (even newlines and EoF). If I try to re-save or copy the file (say via: head file.csv short.txt), this special encoding is preserved. I copied the first ten lines out of vi (which displays it properly) into my Windows clipboard via my SSH client, then pasted it into a new text file, test.txt. This file is visually identical when opened in vi (and similar through 'head', minus the "ÿþ"), although it's roughly half of the filesize. Additionally, file test.txt test.txt: ASCII text file short.txt short.txt: I have no idea what format this once-text file got converted to (it's notoriously hard to search the internet for symbols), but surely there must be some way to convert it back. Any ideas?

• Backup program for Windows using non-proprietary format?

  - by Cristi Diaconescu

  I'm looking at the various local backup programs for windows, and I was wondering which of them use a non-proprietary backup format? By non-proprietary, I mean I want to be able to access at least the latest version of the backed up files either directly, or by using an open-standard format like zip/7z/rdiff... The other thing I'm looking for in a backup program is the ability to create incremental backups. What I have found so far: SyncBack copies files as-is, using separate directories for versioning pretty much the same for all the 'roll you own' task scheduler + rsync/xcopy32/robocopy/MS SyncToy/etc solutions GFI Backup appears to be using Zip files, at least in their 'Business' version, not sure about the free 'Home' version. Didn't try it yet, but it's next on my list. Mozy (!) supports local backup starting with v 2.0 and basically provides a 2nd local copy on a separate partition. Subjectively, it feels slow and resource intensive (I think it took more than a week to finish the first local backup of ~ 300 GB), and does not appear to offer file versioning (arguably, you can get older file versions online). On the positive side, it looks like the local backup is integrated in the restore process which was traditionally a masochistic experience (and this goes for any online backup provider). Other suggestions? I favor ease of use over tons of options (e.g. SyncBack is very flexible but it offers sooo many ways to shoot yourself in the foot...)

• Please insert a disk into SD/MMC - Vista problem [closed]

  - by Naunidh

  Possible Duplicate: Please insert a disk into SD/MMC - Vista problem Hi I tried pushing my 2GB micro SD card using the inbuilt card reader. On clicking the drive I get "Please insert a disk into SD/MMC". This problem is really frustrating. The card works fine on other computers so does the microSD to SD attachment. I have done following o fix. - Updated Vista and installed SP1. - Updated the TI drivers for FlashDrive. - Checked Vaio site for updates (none required). - Added a new entry HKLM\SYSTEM\ControlS* et001\Services\tifm21\Parameters/SDParam=1 took the hint from (http://tinyurl.com/nk33tp) I have restarted the PC multiple times. As soon as I put the card in, the SD/MMC device icon blips, so it seems the hardware is at least detecting something. The card reader was working fine few days back. I guess some windows update has broken something, does any one have any idea on how to proceed. MY laptop is VGN-N365E.

• Solaris: detect hotswap SATA disk insert

  - by growse

  What's the method used on Solaris to get the system to rescan for new disks that have been hot-plugged on a SATA controller? I've got an HP X1600 NAS which had 9 drives configred in a ZFS pool. I've added 3 disks, but the format command still only shows the original 9. When I plugged them in, I saw this: cpqary3: [ID 823470 kern.notice] NOTICE: Smart Array P212 Controller cpqary3: [ID 823470 kern.notice] Hot-plug drive inserted, Port=1I Box=1 Bay=12 cpqary3: [ID 479030 kern.notice] Configured Drive ? ....... NO cpqary3: [ID 100000 kern.notice] cpqary3: [ID 823470 kern.notice] NOTICE: Smart Array P212 Controller cpqary3: [ID 823470 kern.notice] Hot-plug drive inserted, Port=1I Box=1 Bay=11 cpqary3: [ID 479030 kern.notice] Configured Drive ? .......

NO But can't figure out how to get the format command to see them so I know they've been detected by the system.

• Convert HTACCESS mod_rewrite directives to nginx format?

  - by Chris

  I'm brand new to nginx and I am trying to convert the app I wrote over from Apache as I need the ability to serve a lot of clients at once without a lot of overhead! I'm getting the hang of setting up nginx and FastCGI PHP but I can't wrap my head around nginx's rewrite format just yet. I know you have to write some simple script that goes in the server {} block in the nginx config but I'm not yet familiar with the syntax. Could anyone with experience with both Apache and nginx help me convert this to nginx format?

• Kerberos service on win2k dc will not start following disk failure

  - by iwilson68

  Hi, I have a win2k (mixed mode domain) with 4 DCS. One of these also acts an exchange 2000 server which uses 2 logical volumes from an MSA 2000 array. AD etc is stored on local drives. We experienced a problem last week when the raid array fell back to a redundant controller and this temporarily meant that the two logical drives were not visible to the server for around 5 minutes and a couple of reboots. The log records these Events as Type: Warning Event Source: Disk Event Category: None Event ID: 51 Date: 06/11/2009 Time: 11:46:23 User: N/A Computer: server1 Description: An error was detected on device \Device\Harddisk1\DR1 during a paging operation. Following these problems, the server “kerberos Key Distribution” service refuses to start with an “error.31 a device attached to the system is not functioning”. All other automatic start services (including net logon) are running and there are no DNS issues etc. All devices are also functioning but the two logical MSA disks are now numbered in the Windows Disk Management MMC as 2 and 4 and I suspect that they may have previously been identified as disks 1 & 2 and perhaps windows still sees this as an ongoing failure?? Replication has not been affected but obviously there are many audit failures in the security log relating to users and workstations presumably linked to the Kerberos issue. Attempting to manually start the kerberos service generates the following in the System Log. Event Type: Error Event Source: Service Control Manager Event Category: None Event ID: 7023 Date: 09/11/2009 Time: 09:46:55 User: N/A Computer: Server1 Description: The Kerberos Key Distribution Center service terminated with the following error: A device attached to the system is not functioning. DCDIAG passes all tests except “Advertising” and “Services” which I believe relate directly to the failure of Kerberos only. Any advice would be appreciated.

• How to transfer Windows Vista disk image to new machine

  - by Mike Hobbs

  I'm trying to upgrade a user's machine to some better hardware. I know of Easy Transfer, but I'd rather not have to reinstall all the programs that are already present. (Some of which are no longer available, anyway). Instead, I'm trying to transfer the entire disk image from one machine to the other, but I ran into issues. If I copy the partition image over to the new machine using Clonezilla, I get errors on boot saying that I need to insert the Vista install disk and run repair. I do that, but it then says that it is unable to repair whatever it is that's broken. Next, I tried to sysprep the old machine before creating the image, but sysprep fails saying that it encountered some sort of system error. Should it be possible to sysprep any arbitrary machine, or does it only work on a relatively clean install? Could it be a missing driver that is tripping me up? The new machine is a fairly stock desktop that shouldn't need any special drivers beyond what's already present in standard Vista. Are there any foolproof methods for doing this sort of thing?

• Disk IO slow on ESXi, even slower on a VM (freeNAS + iSCSI)

  - by varesa

  I have a server with ESXi 5 and iSCSI attached network storage(4x1Tb Raid-Z on freenas 8.0.4). Those two machines are connected to each other with Gigabit ethernet. The raid-z volume is divided into three parts: two zvols, shared with iscsi, and one directly on top of zfs, shared with nfs and similar. I ssh'd into the freeNAS box, and did some testing on the disks. I used ddto test the third part of the disks (straight on top of ZFS). I copied a 4GB (2x the amount of RAM) block from /dev/zero to the disk, and the speed was 80MB/s. Other of the iSCSI shared zvols is a datastore for the ESXi. I did similar test with time dd .. there. Since the dd there did not give the speed, I divided the amount of data transfered by the time show by time. The result was around 30-40 MB/s. Thats about half of the speed from the freeNAS host! Then I tested the IO on a VM running on the same ESXi host. The VM was a light CentOS 6.0 machine, which was not really doing anything else at that time. There were no other VMs running on the server at the time, and the other two "parts" of the disk array were not used. A similar dd test gave me result of about 15-20 MB/s. That is again about half of the result on a lower level! Of course the is some overhead in raid-z - zfs - zvolume - iSCSI - VMFS - VM, but I don't expect it to be that big. I belive there must be something wrong in my system. I have heard about bad performance of freeNAS's iSCSI, is that it? I have not managed to get any other "big" SAN OS to run on the box (NexentaSTOR, openfiler). Can you see any obvious problems with my setup?

• How harmful is a hard disk spin cycle?

  - by Gilles

  It is conventional wisdom¹ that each time you spin a hard disk down and back up, you shave some time off its life expectancy. The topic has been discussed before: Is turning off hard disks harmful? What's the effect of standby (spindown) mode on modern hard drives? Common explanations for why spindowns and spinups are harmful are that they induce more stress on the mechanical parts than ordinary running, and that they cause heat variations that are harmful to the device mechanics. Is there any data showing quantitatively how bad a spin cycle is? That is, how much life expectancy does a spin cycle cost? Or, more practically, if I know that I'm not going to need a disk for X seconds, how large should X be to warrant spinning down? ¹ But conventional wisdom has been wrong before; for example, it is commonly held that hard disks should be kept as cool as possible, but the one published study on the topic shows that cooler drives actually fail more. This study is no help here since all the disks surveyed were powered on 24/7.

• sql 2008 disk layout on a budget this is for database mirroring

  - by user22215

  Guys I'm rolling out a SQL database server that will be used to back Sharepoint 2007. Right now I need some advice on my disk layout. I have two Dell servers that are configured a little differently in terms of storage. The principle server will be using a combination of local storage and san storage. I have to work with what I have the organization is currently all allocated on san storage it was like pulling teeth to even get what I have to work with now. My disk setup on the principle is as follows: raid 1 for OS raid 10 for logs raid 10 fiber on san for high IO databases raid 10 sata on san for content databases My question in regards to the principle server is where should I place the temp db? I thought about placing it on the fiber raid 10 which will be hosting my high IO Sharepoint SSP databases my only other choice is to move it to the raid 1 os partition which I’m sure you guys will be against. Now let’s talk about the mirror server it is not connected to the san it is all local 6 15k SAS drives. Now my question is the same do I put tempdb on the os partition or do I leave the os partition and use a single raid 10 for everything? Any help you can provide is much appreciated.

• Not able to access external Hard disk

  - by Jash Jacob

  I have a 1TB External Hard drive which I'm currently not able to access. When I open the External drive in Finder, It shows it's empty. When I use the option to "Get Info", I get the dialog box stating it has about 300GB Free. Tried to get into the External Drive using Terminal, I had no luck. Checking in Disk Utility, It showed that I have many number of files but ZERO folder. I tried to "repair disk", in the process the external Drive got unmounted in between the process. I checked this drive on Windows. I was able to open almost all the folders but I wasn't able to copy anything onto the external drive. One folder caused my windows computer to hang, So i connected the drive back onto my MacBook Pro and tried to access the drive through terminal (this time it worked!) and then I tried to delete the folder with rm command, I got an "input/output error" What should i do to recover the files in that folder? How can i access my external drive on my mac
