Failing hard drive, extremely slow chkdsk

Any ideas what I can do about a hard drive which is failing? It took a slight knock, equivalent of about a 1cm fall, and was disconnected at the same time. Probably the disconnection while being used caused the problem.

It is given a drive letter in windows, but cannot be opened in file explorer, and disk management doesn't know much about it beyond the drive letter.

It doesn't make any funny noises or clicks, sounds normal. Seatools reports some errors and a long failed test but it passed the short test.

chkdsk f: /r is running and recognises that the disk is NTFS and its volume label.
It is currently at stage 1: examining basic file system structure. Progress: 39 of 166144 done. ETA: 999hours. About 10 seconds for each item.

It has given some "file record segment xx is unreadable" errors already.

Any suggestions? Leave it while I go on a week's holiday and see if it finishes?

(Yes I know I should have backed it up. I also tell everyone to back up their stuff but never get round to it myself!)

It would be practical if you clone that problem drive to healthy working drive with ddrescue and recover your files from the clone drive you got.

if it suffered mechanical damage, that long a chkdsk may just kill it off entirely. You should use dd_rescue to clone the drive to a new disk of the same size, and then clone that disk again to a new disk, and attempt recovery there.

If you cared at all about your data, you would have had it backed up.

Update: there are a lot of steps involved in the guide to ddrescue and the P2 explorer software recommended for one of the steps costs $199 (unless you have access to an old 32 bit system in which case you can use the free version).

I had success with UFS explorer (standard recovery version) which is 40 euros ($55) for a personal licence. Very easy to use. Bad sectors had distupted the file system but the software was able to recover all my files and folders. You can use the trial to check if it is able to see your files.

So I recommend trying UFS explorer to anyone with similar disk corruption problems.
