• How do I transfer a Windows 7 installation to a new HDD?

  - by Nidonocu

  I've just got all the parts I need to build a new PC but the SATAII hard drive I ordered did not come and I've received an IDE drive instead. While I wait to get the correct drive type and send the new IDE drive back, is it possible to install Windows 7 on to an existing IDE drive that I have and then transfer the contents of that drive over to the new SATA disk when it arrives without Windows having any issues?

• How can I accurately determine the age of a hard drive?

  - by Todd Stout

  Yes, if it's large, heavy, and only 65 Meg in capacity, you can assume it's ancient. An RLL controller would positively indicate the drive is from antiquity. What about drives that are only 3 or 4 years old? If I know the serial number, make and model is there a public database that indicates a manufacturing date? Update: As trite as this question might seem to some, the hard drive I was looking at that precipitated this question had no obvious manufacturing date stamped on it. I realize that most do. I think the answers given are very useful to myself and others.

• I/O errors are reported when I try to install Ubuntu, but the SMART data is good. Is my hard disk dying?

  - by James

  When I try to install linux, it tells me there is an input output error on dev sda. I have tried both Ubuntu and Mint on two different computers. So that narrows it down to the hdd. After hours of googling and trying different things I tried making the hardrive ext4 with gparted but that comes up with an error. This makes me think that the hdd is bad. There are a few reasons I think the hdd isn't bad. I can use the hdd in windows fully. Windows and gparted disk health checks both say it is fine. Its SMART data is all good. So... help?

• Can't mount external hard drive

  - by tezza

  i have a problem accessing the data on my external hard drive. I recently did a fresh install but mistakenly left my external hard drive plugged in. When I tried to access the data on the external HDD, it says "no files" but recognizes that there is 290 GiB of data on it. The HDD is 350GB big. I checked the drive with Disk Utility and it showed that the hard drive had a bootable flag. So, in the edit partition, I unchecked this bootablity. Now it won't mount in Ubuntu and now my XP can't recognize it at all, whereas I could access the data on the XP machine before. In disk utility, it doesn't give me the option to check the bootable box in again and I can't access the data on XP either. Any ideas on how to fix it?

• Installing Ubuntu by writing on the Hard Drive

  - by Alexandros Marinos

  I have a laptop whose CD drive is not operational and is too old to boot from a flash stick. I have bought a new hard drive for it for which I have an enclosure. Is there a way to configure the disk as an external to my current ubuntu setup, copy some form of ubuntu on the hard drive, place the HD in the old laptop, and have ubuntu install ubuntu from there? Effectively what I am asking about is some sort of live cd that installs on itself (since the HD is writeable).

• Intuitive view of what's using the hard drive so much on Windows 7?

  - by Aren Cambre

  Sometimes my hard drive usage is near 100%, and I have no idea what is causing it. Are there any utilities that can help diagnose excessive hard drive usage and have as intuitive of an interface as Task Manager's Processes tab, which I can sort by CPU usage? I am aware of using procmon, of adding columns to Task Manager's Processes tab like I/O Read Bytes and I/O Write Bytes, and using Resource Monitor's Disk tab. Too often, these don't give me useful information or clearly identify a single process that is hogging the disk.

• 4K sectors transition: Why are hard drives moving to 4096 byte sectors, vs. 512 byte sectors?

  - by Chris W. Rea

  I've noticed that some Western Digital hard drives are now sporting 4K sectors, that is, the sectors are larger: 4096 bytes vs. the long-standing standard of 512 bytes. So: What's the big deal with 4K sectors? Is it marketing hype, or a real advantage? Why should somebody building a new PC care, or not, about 4K sectors? Why is this transition taking place now? Why didn't it happen sooner? Are there things to look out for when buying a 4K sector hard drive? e.g. incompatibility? Anything else we should know about 4K sectors?

• Should I use VFAT or ext3 for a 1Tb external usb hard drive?

  - by ihuston

  I have a 1 Tb USB external hard drive which I want to use to backup data from my home and office desktops (both running Linux). Should I format the drive (possibly split into a few partitions) as vfat or ext3? I don't anticipate using the drive with Windows very often so this is not a primary concern. The main thing holding me back from just using ext3 is the problems you can have when two different users (home and work accounts) try to access each others data. Is there any way to mount an ext3 drive with user id mapping?

• My Portable Hard Drive with USB3 didn't work when connected to My Laptop, but it working with USB2 properly

  - by Mohammad Hasan Esfahanian

  I have Western Digital My Passport Essential Portable Hard Drive with USB3 and Model:WDBACY5000ABK-EESN. Until about two or three months ago when I connected that to My Laptop USB3 port, that worked very well. But now when I'm connecting that to My device, The system does not detect any Hard Drives. When plug in the USB2 port is working properly. I connected that to another Laptop whit USB3 port but I had the same problem. I tested My Laptop port with a Flash Memory by USB3 and ports were healthy and I'm sure they are working. For this issue, I changed the windows, but it still did not work. What can I do? Thanks in advance.

• Unable to detect windows hard drive while running Ubuntu 12.04 from USB

  - by eapen jacob

  I am completely new to Ubuntu. I experimented with Ubuntu 12.04 by running it from a USB drive, in-order to recover files from my hard disc. History: My laptop is an IBM R60 running windows 7. Suddenly it gave me an error stating "error 2100 - Hard drive initialization error". I have read all the forums and most of them suggested that I remove and replace my HDD and that did not work. And one site suggested to try using Ubuntu to recover files. I booted my system from USB, and once Ubuntu came up, I choose "Try Ubuntu". It came up fine and I was able to surf ,and do other things, etc. I was unable to to access my files which are on the hard disc and "Attached Devices" is grayed out. 1- Is there any way to gain access to my hard disc to recover the files? How do I navigate to search for my files. 2- Is it just simply not possible if the hard disc themselves are not working? Is that why I`m unable to find the drives. I know its a very novice question, but hoping someone would help me out. Thank you, Eapen

• Why is my HDD going back from standy?

  - by Pablo

  My hard drives, connected to Ubuntu server are producing the following log every exactly 5 minutes. Nov 1 14:10:50 localhost kernel: [ 1602.884936] ata2.00: hard resetting link Nov 1 14:10:51 localhost kernel: [ 1603.226804] ata2.01: hard resetting link Nov 1 14:10:52 localhost kernel: [ 1604.274533] ata2.00: SATA link up 3.0 Gbps (SStatus 123 SControl 300) Nov 1 14:10:52 localhost kernel: [ 1604.274548] ata2.01: SATA link up 3.0 Gbps (SStatus 123 SControl 300) Nov 1 14:10:52 localhost kernel: [ 1604.356669] ata2.00: configured for UDMA/133 Nov 1 14:10:52 localhost kernel: [ 1604.375247] ata2.01: configured for UDMA/133 Nov 1 14:10:52 localhost kernel: [ 1604.375265] ata2: EH complete I don't think this is related to hard drive failure, because it happens for ALL hard drives connected and ONLY when I write spindown_time = 12 in /etc/hdparm.conf. The reason I add this value is to put disks into standby mode after 60 seconds, which is happening after that period (checked with hdparm -C). The first clue I thought that smartd was running and spinning the drive. However, I couldn't find it in ps -aux | grep smart. Additionally, iostat does show that nobody accessed those drives, since Blk_read, Blk_wrtn remain unchanged. I also killed all processes that may be doing something with hdd(eg SAMBA). So I guess the problem is solely with hdparm... I have no more clue where that 5 minute value hides.

• Not detecting HDD after installing Ubuntu 12.04!

  - by Arthur

  After installing Ubuntu 12.04, which I'm using right now and it works great, my extra hard drive was detected the first time I turned on my computer but then it does not show anymore on my Home Folder, when I run the Disk Utility says that has a few errors but when I try to fix it, says that hard drive is busy and cannot do anything else. I've unmounted it and mounted again but nothing happens. Do you know what can be going on? Cause the first time that I was able to see my hard drive it had all the files I have, but I don't know if deleting the partition will format the whole hard drive or just the ubuntu files. THANKS in advance! BY THE WAY, I'm new to Ubuntu... :S

• Ubuntu made my second HDD disappear from the BIOS!

  - by RWLarsen

  My netbook, an ASUS 1015PX, shipped with two harddrives. After switching to Ubuntu, the second drive isn't recognized by the OS or the BIOS. I've never formatted the second drive, so it's still set up for use by Windows. I guess I don't care about the data on the drive, I'd just like to be able to use it again. It's probably also worth mentioning that I'm very new to any form of Linux, so I'm remarkably new to the Terminal.

• Is there a limit of max. number of files in external hard drive folder?

  - by tfs

  I have a FAT32 external hard drive where I keep backups downloaded from webserver. I have a directory with 30 subdirectories. One of the subdirectories contains 21381 files and when I try to copy more files into this directory I get 0x80070052 error. However,it's possible to copy one more file in this directory (only one) if I make it's name shorter (8 characters instead of 22 as it's original name). How do I solve this problem? Now I can not synchronize external hard disk files with server files which is very important for me.

• Hard drive skipped in boot

  - by Yasin

  Good evening. I just installed Ubuntu 12.04 using a USB, but right after the install, after restarting the machine, I get a message asking me to insert a bootable drive. My boot settings in Bios have the hard drive first, then DVD, then USB stick, and I have two systems installed, Windows 7 and Ubuntu 12.04. I suspected the hard drive got somehow disconnected internally, so I checked but everything was in place. I used the live USB to start Ubuntu, and I could see the hard drive and mount whatever partition I wanted. The one that contains the recently installed Ubuntu, looks the same. (It hasn't been deleted or anything). I'm not sure if this is a hardware problem or a loader(grub) problem, because the hard drive is visible. Only it isn't seen by the BIOS. My only means of internet connection is a USB modem, which doesn't work when I'm using the live USB, so I have can't download anything from the internet, in case someone asks. I also reinstalled Ubuntu 12.04, to no avail. This is my second problem with this laptop, and Ubuntu, and it's not even a week old. I hope this one gets solved. Thank you.

• Debian - Problems Unmounting External Hard Drives

  - by user331981

  I recently installed Debian Testing on a new laptop and I just noticed that I am having some issues with unmounting external hard drives. I am using Mate Desktop 1.8.1. With the 1st drive, if I right click on the drive and select “safely remove”: The drive unmounts, spins down, immediately spins back up an remounts. Unable to unmount. With the 2nd drive, if I right click on the drive and select “safely remove”: The drive unmounts but does not spin down. With the 3rd drive, if I right click on the drive and select “safely remove”: The drive unmounts but does not spin down, immediately spins back up but does not remount, and after 20 seconds, it spins down and stays that way. Behavior is the same on both USB 2.0 and USB 3.0 ports. On my last laptop, on which I also used Debian Testing + Mate desktop, the safe removal of drives worked out of the box and I never had an issue with it. The drives would unmount, spin down and stay that way. To remount the drive, one needed to unplug the device and plug it back in. I am unsure how to troubleshoot this issue and I am not sure if it is merely a matter of installing a “missing” package of editing a config file. Thank you in advance.

• External Hard disk not workng on windows after I formatted it on Ubuntu

  - by nav_jan

  I formatted my Western Digital 500 Gb hard disk on Ubuntu 10.4 and now I want to use it on Windows 7 but it cannot detect it. I formatted it with FAT(applicable to all) option. I tried to Google this problem a bit and as suggested by one of the site i tried to format this drive with NTFS. Still windows cannot detect it. Drives in windows 7 is not a problem because I tried a different usb drive on it and it works. I can see the led of the drive glow when I connect it and I can also see remove drive safely option in lower right corner, but i cannot see any option in "my computer" to access the hard disk. I am new to Ubuntu. Any help is appreciated.

• New 2.5" hard drive for laptop - What to compare?

  - by TFM

  I'm having trouble finding a new (bigger) hard drive for my laptop. I came across some criteria that I never thought about before, while I was checking a price comparison site. Of course, that made me more confused. First of all, I will probably go with something above 250 GB, and at least 16 MB cache. Now the confusing part: Most new drives are 7200 RPM, as opposed to good old 5400 RPM. 7200 RPM used to mean extra heat, but suddenly it's almost impossible to find a 5400 RPM in 2.5". What did I miss? Second question: Internal data transfer rate. My old drive has a rate of around 60 MB, but new drives have values like 100 MB or more (e.g. 150 MB). How important is this "internal data transfer rate"?

• How to get entries from the second level query cache ?

  - by fabien7474

  In my grails application, I want to display all the current entries of the second-level cache from all regions. My code is as following : def getCacheStats() { StatisticsImpl stats = sessionFactory.statistics for (regionName in stats.secondLevelCacheRegionNames) { log.debug stats.getSecondLevelCacheStatistics(regionName).entries } } However everything works fine as long as the region name is not org.hibernate.cache.StandardQueryCache (region used for Query Cache). In that case, an exception is thrown : java.lang.ClassCastException: org.hibernate.cache.QueryKey cannot be cast to org.hibernate.cache.CacheKey Having googling around, I didn't find any clues about how to display the list of entries of the cached query result sets associated with regions StandardQueryCache and UpdateTimestampsCache. Could you please help me find a solution for this?

• What is the best way to implement an object cache with Entity Framework?

  - by Harshal

  Say I have a table of "BlogPosts" in a database and i want to be able to cache the ones that were retrieved already in memory, for further reads, I can just use a standard hashtable type memory cache like System.Web.Caching.Cache, but if i then need to update a property on one of these blog posts e.g. blogPost.Title and update the record in DB, i cannot do this without fetching it again from database as the Entity Framework context used to fetch this record when it was loaded into my cache is already disposed? How do I write code so that I am getting an object from my cache, updating one property and just calling the SaveChanges method without incurring an extra read.
