I can no longer access my external hard drive after running a chdsk on it. It shows up on My Computer but it doesn't have the usual info under it about how much free memory there is like the other drives. When I click on it, a window pops up saying that I need to format the disk before I can use it. I don't know what's wrong. Please help!

What does the disk show in Disk Management? Is it listed as RAW or not initialized.

 

Doing a chkdsk on a failing drive or one whose file system is severely corrupted can do more harm than good.

I agree with you, if there is data on it, do not format it.  What happened with the computer's external hard-drive that led to the chkdsk? If possible, use Windows 7(?) disk management and post a screen-shot, which will include the external HD if attached.

Perhaps you would like to say what type disk it was or is?

Thanks for all of the replies. Every time I run Disk Management with the external hard drive plugged, it freezes and stops responding. As soon as I unplugged the drive, Disk Management unfreezes, 

 

What happened was that I had a little accident with the hard drive and it was knocked off the table. When I plugged it back in, everything seemed normal. But when I tried to transfer a file onto the drive, it lagged. I had to restart the computer. As a precaution I ran chdsk on it. But after doing so the drive became no longer accessible.

 

The drive is a Transcend StoreJet 35T3.

If this hard drive was dropped then I would say any software recovery is not going to work if it freezes once you attach it. If you need data off the drive then you would need to consult a professional data recovery service which is not cheap. It all depends on how much this data is worth to you. 

 

Sometimes booting a live linux disk can pull data off the drive where Windows fails but I doubt it would work in this case but you can give it a try if a professional service is out of the question.

"...What happened was that I had a little accident with the hard drive and it was knocked off the table..."

This should have been mentioned upfront -- it changes everything, according to data recovery specialists, of which I am not.

A data recovery company/specialist is probably going to be the only safe bet at this point.  Very likely, any further DIY attempts will result in much higher recovery cost and a lower recover success.

Thanks for the replies. I'll send the drive in to be looked at. Thanks again.
