the same size (check the number of LBA sectors) or larger; when larger, it's usually not a problem because the number of heads per cylinder and sectors per head will be the same if both testdisk no partition found disks use LBA mode. Windows may have some problems in dealing with bad sectors on a damaged hard disk, so the best solution is to use a Linux OS to copy data to another hard disk. You can also use TestDisk to help analyze the sectors copied from a hard drive with physical problems onto a good drive.

Burn the .iso file to CD Boot from the CD-ROM At the boot prompt, type knoppix lang=us for a US keyboard/language. You are automatically logged in as the user 'knoppix' on a GUI console. Launch a Konsole/terminal(Note: Knoppix has a separate 'Konsole as root' choice, but copy/paste functions are deactivated in it, so we always recommend using the method described below for gaining root privileges from the normal user Konsole.) Knoppix comes with TestDisk, PhotoRec, dd and dd_rescue. To access hard disks, you need to run these utilities with root (Administrator) privileges. To become root from the Knoppix user account, select the Konsole and type sudo -s, then press the Enter key. Now you can use all of the powerful root commands you need for full disk access from this console. N

cycled to return. Chkdsk wouldn't work on the drive. I'm using EaseUS Partition Master to test the drive now, it's only 25% done yet it has already detected 44270 bad sectors. Is there any way to isolate and avoid these bad sectors just http://www.cgsecurity.org/wiki/Damaged_Hard_Disk to access the drive once more and salvage whatever is on it? I'd like to do this before I RMA. The drive was used mainly as a backup, but there are some unique files I need to pull off. I used Photorec to recover some of the files, but the problem is nothing is named and it will take weeks to sort through to figure out what is a backup and what is an original. It took about 5 hours to complete that, and that wasn't even http://www.tomshardware.com/forum/286715-32-dead-drive-bypass-sectors the entire drive. It's a 3TB so if I recovered the entire drive, the estimated time of completion was 150 hours and increasing. TL;DR I don't care about the corrupt files on the bad sectors, what's gone is gone. I just want to be able to access the drive and selectively copy off the small percentage of files I need. Any help would be greatly appreciated!
