USB hard drive not recognized and freezes computer

I have a 20gig Soyo Cigar hard drive (NTFS). Its not flash its mechanical.  All of a sudden when i connect it to ANY COMPUTER, windows makes the usb connected "ding" sound and then the computer freezes (i can still move the mouse but i cant open any files or programs)till the hard drive is disconnected.  I try connecting it with "My Computer" open and no drive appears.  It dosnt recognize it at all.  I tried from safe mode and i get the same thing.  I've tried to restart the computer with the drive connected and it wont get past the "Windows is starting" screen.  I have very important files on the drive and reformating is definitely a last resort.

Try removing the hard drive from the external casing and install it in another external housing (that you can either borrow from someone or buy).

If it still doesn't work, there is probably something wrong with the disk itself. Otherwise, the problem will be the chipset/USB interface on the device.

If you're hearing clicking sounds from the drive, it's likely the hard drive is about to die.

First try the drive on another PC and tell us if you can access the data from there. Depending on that we can give you further advice.

It says in the original post that it doesn't work on any computer. I am assuming he/she has already tried it on another PC.

In that case geet a copy of knoppix and try using that to access the drive. If that can be done, copy the data off with that OS. If it doesn't work, you can try removing the disk from the case like was mentioned already, but try connecting the disk to an internal connector of the PC. If neither works, you are left with a data recovery agency, of which gillware is probably the best.

since the PC's freeze when the drive is connected,  i would think the external case is bad .
If you stilll got warranty, you can ask for a replacement, otherwise i suggest to Open the case, and connect the drive to an IDE cable, and backup your data. If the case is bad, you only have to buy a new , empty case.
If the drive is bad, you'll have to buy another drive.
if you need to recover data from it, pick one of these :

Well,  with knoppix i can see the hard drive and the data on it on the linux platform. BUT....It wont let me transfer the data from the external USB DRIVE to my computer hard drive.  It wont even let me create a new folder on my computer hard drive .

go to www.runtime.org and use getdataback to recover your data.  It works.  The difficult part you have is getting the drive to be recognized without freezing the system.  Safe Mode wont do, because it wont find USB drivers.  YOu will just have to try on whatever system will free up the interface after you plug the drive.  Good luck

Depending on what filesystem your destination disk is formatted in, you can use knoppix to copy the files. It must either be fat32 or a linux filesystem, as knoppix doesn't have internal writing support to ntfs. So, if there is a fat32 volume on the PC, you first mount it, then right click on the icon and turn on writing access to the disk. If you don't have a local fat32 partition, you can still use knoppix to copy the data to a networked drive on another PC. Being on a network that partition can be anything, the filesystem isn't important as that is transparent to the client OS.

I greatlt appreciate all your replies.  KNoppix did the trick once i brought a third hard drive(FAT32) into the picture.  I managed to save all my data.  And learned a few things about Knoppix which i never knew existed.  If anyone knows of any dos based disk repair software please email me at ntorres38 at gmail dot com

Use the manufacturer's tools, or download the UBCD which includes the tools of most manufacturers.
