Dear Experts,

Slaving a suspect drive just crashed my computer,
so I now have it in an external USB enclosure.

The file system is corrupted and it can be difficult to spin the drive up.
I have recovered the data which was in separate folders,
rather than in any of the 'system' folders, My Docs etc.

Granted that the HD may have had it, but I would like
to know if it is possible to fix the file structure.

Is there any way to run chkdsk on this 'external' drive.

In Tools, error checking, Windows cannot do it
and running chkdsk from the command line
results in the message 'cannot open volume for direct access'

It was a WinXP Home SP2 installation.

Any suggestions would be appreciated, or is it fit for doorstop,
rather than for purpose.

Thankyou.

If you've tried various methods of reading the drive...and all were unsuccessful...and the jumper was properly set for each connection...I'd have to say it's going, if not gone.

Anytime I've had file structure problems, I found that a clean install was my chosen solution.

You can run chkdsk on any drive from the command prompt (if the disk will allow it).
To do this, go to Start...Run...and type in "cmd.exe" (without the quotes) and press Enter
In the black window that opens up type "chkdsk X: /r" (without the quotes) and press Enter
There must be a space between the chkdsk and the X:, and there must be a space between the X: and the /r
Replace the X with the letter of the drive that you want to check (leave the colon there).

If it won't run there, then there's a problem with the disk that Check Disk can't fix.

Thank you Louis, I agree. I have the most important part, i.e. data, so I am now treating fixing the disk as an exercise only.
One thing I have learned is that blue screens, 'unmountable volume' & disk boot errors, do not necessarily mean that one cannot recover the data.
Pete

John, thank you. I have already done the things you suggest and get 'cannot open volume for direct access' as mentioned in my post.
Anyway, the data is safe, so my colleague is content, has a new HDD and has learned the lesson about backing up.
Loved The Knack, first time of hearing.
Regards from the UK

I would download a manufacturer's diagnostic and run it on the drive and see if a low-level format can salvage the drive for storage purposes.

Run the long diagnostic test first, before the low-level format.
