Hard drive rescue help, please


I have a Western Digital external hard drive that is failing. The problem is intermittent and I am trying to rescue the data from it. If I cycle power repeatedly, I occasionally get about 10 minutes of operation out of it before it dies again. I have managed to rescue about 100GB of data from it so far, but it is working for shorter periods of time and it is taking more and more recycles to get it to work.

When I plug it in and it doesn't get "seen", dmesg gives me:

Quote:
[ 240.523492] sd 7:0:0:0: [sdd] Add. Sense: Logical block address out of range
[ 240.523498] sd 7:0:0:0: [sdd] CDB: Read(10): 28 00 00 00 00 00 00 00 08 00
[ 240.523509] end_request: I/O error, dev sdd, sector 0
I suspected the power supply. So, I broke open the whole thing and inside is a WD Caviar WD500AAVS SATA hard drive with a USB controller board. I took the hard drive and plugged it into an open SATA port, but the motherboard never sees it. I reattached the controller to the drive and use it as a USB drive again as I had more luck that way.

The odd thing is that Windows will see it fairly consistently as a USB drive. However, I used a LUKS encrypted EXT3 file system and I can't seem to get Windows to mount it. I can unlock the drive, but then Windows cannot recognize the file system even with the open source ext2 driver.

Any help with this is appreciated.

Thank you for your fast response.

Unfortunately, the biggest problem is getting the system to "see" the device. It keeps disappearing while under Linux or never appears to begin with.

If it's a usb device you don't plug in until prompted by clonezilla so you may be able to get it plugged in long enough to make an image of the drive.

I did figure out how to get an encrypted ext3 partition to mount in Windows. This is good, because Windows seems to be able to keep the hard drive up for an hour or so at a time before it dies again. I managed to get about 75GB copied off this morning. Only another 200GB or so left to go.

If windos can do it clonezilla will read & copy as an image then you can restore os to another drive

It seems the hard drive is having trouble spooling up. As the drive warms up, it dies. I may try the freezer trick....

I would not recommend to use any "tricks" before you have tried to get the rest of your data from it. Such "tricks" may damage the disk even more and can make any rescue attempt futile.

For the future consider a good backup plan, so that such situations don't occur.

For some odd reason, putting the HDD on its side seems to be working. Several hours of uptime now.

I'm probably going to keep this circuit board. It seems to be a convenient way of hooking up a hard drive. (Tape not included).

Did you get all of your data out yet?
If u have that much uptime then clone it.
