View Full Version : HDD recovery problems, not visible in Testdisk or GParted

Hello forums!
Got a bit of a problem with a WD 2TB HDD. Ever since I moved my computer to my new place I haven't been able to access this drive. It shows in file manager as 'DATA' mounted at sdb1 which would be correct but it seems to always be busy, can't do anything with it. It won't show up in Testdisk or GParted. I managed to unmount it via terminal and still nothing. Originally I was able to view it in Knoppix but the partition table was messed up. I had tried restoring it with Testdisk to no avail. Eventually it stopped showing up in Testdisk and GParted at which point I gave up (A few months ago).

Now I just want my drive back, I've given up on recovering the data (although that would be fantastic) I just can't make do with my little 500 GB backup drive anymore, those 2 TBs would really come in handy. The drive shows in BIOS as well, just not useable from knoppix. It shows in Windows as a drive but has no info. It does have correct information in Knoppix regarding size and gives a believable reading for free space from what I remember.
Does anyone have any clue as to what the problem could be or what I could do to remedy it? I'm sure there's a command result I should be posting but I'm fairly new to Linux, especially Knoppix so treat me as a noob :D
Let me know if any additional information is required.

Thanks in advance!

... first of all open a console and tell us the output from

blkid and from

fdisk -lYou can also try (don't post it)

hwinfo --disk
hwinfo --partitionand have a look at all the lines "Config Status:"

Perhaps the drive is physically damaged.

Nothing in there about the disk...

ran hwinfo --disk and the info regarding sdb is:

... have you already formatted
/dev/sdb1: LABEL="Data" UUID="EA4C906C4C903573" TYPE="ntfs"
with Windows-Tools? This will take a very long time!

I believe I used Gparted before it stopped working. I remember using Testdisk to try to restore the partitions but it never worked out.

... with GParted you can create a partition and select NTFS formatting. But it isn't really NTFS formatting; you have to do this with Windows tools.

It was probably formatted with Windows then. The drive has always been NTFS.
