Will formatting remap the bad sectors and is it safe to use or i/o error 23 should I throw it away? The exact error is "The device, \Device\Harddisk1\DR1, has a bad block.." GetDataBack reports it as an error 23. The drive is a WD Raptor.

I would NEVER use a disk that reported bad sectors, when there's one, there will be more. share|improve this answer answered Jan 21 '11 at 19:23 DanBig 10.6k12048 Even in a raid 5 array at home? –rboarman Jan 21 '11 at 21:41 Yep.

I/O error, dev sda, sector 545868115 up vote 10 down vote favorite 2 Since a few days ago, my computer freezes whenever I sync my HDD with an external USB3 drive. When the keyboard gets temporarily a bit responsive I am able to switch to another terminal (Ctrl+Alt+F2) and I see the following image repeating continuously. I am on Ubuntu 11 using LuckyBackup. What is going on? Is my hdd defective? Is it the external one? Something else? Many thanks! external-hdd sync share|improve this question edited Feb 20 '12 at 14:01 James♦ 31.1k44133224 asked Feb 17 '12 at 11:44 Pomario 79831223 I'd bet that your hard disk is failing. Use the Disk Utility to verity it's smart status. –Javier Rivera Feb 17 '12 at 11:53 3 @JavierRivera Can you include a answer with instructions on how to do that? Leaving a half-answer as a comment can often cause more harm than good. Thanks. :) –James♦ Feb 17 '12 at 12:49 add a comment| 2 Answers 2 active oldest votes up vote 9 down vote accepted You need to check and see if your disks are indeed failing. There are command line tools for monitoring SMART data (which is data that the hd reports about it's own health). sudo apt-get install smartmontools gsmartcontrol Gsmartcontrol is a gui version of the same tool, and is very easy to use. Select the disk and run a short or long test in addition to viewing any errors the hd is reporting. To run via the the command line, do the following sudo smartctl -i /dev/sda Make sure SMART is turned on. If not, sudo smartctl -s on /dev/sda Finally, run sudo smartctl -a /dev/sda or if it's a serial ata drive. sudo smartctl -a -d ata /dev/sda See this link for more info about smartmontools. http://sourceforge.net/apps/trac/smartmontools/wiki/TocDoc share|improve this answer answered Feb 17 '12
