I have a 1TB WD Caviar Blue HDD that I have been using as an external by taking apart the USB to SATA interface from another external drive and plugging it in to this one.

A few months ago I dropped it on to a hard surface from approx. 2 ft. I tried to connect it to a Cirago NUS1000 USB network adapter after this and the drive wasn't listed as being present. Then, because it was formatted as EXT2, I installed EXT2 IFS and attempted to use it on a laptop. The drive is recognized but it locks up my computer. It also shows up under disk management with the correct partition info and everything (Linux swap). While the drive is attempting to load it keeps spinning and clicking (as if the arms are moving out and back in in a periodic fashion).

I am using Vista on an HP laptop with dual core 2.1 GHz AMD processor and 3GB RAM. Not that that would matter at all...

Is there any way I could retrieve my data or, ideally, restore the drive to working order? In the long run I want to put an NTFS partition on the drive and copy all files to it so I can use it on a PS3. I bet that will be difficult because it is in ext2.

Thanks in advance.

Sounds like a head to platter collision. The most notorious cause of hard-disk failure is a head crash, where the internal read-and-write head of the device, usually just hovering above the surface, touches a platter, ( probably happened when it was droped) or scratches the magnetic data-storage surface. A head crash usually incurs severe data loss, and data recovery attempts may cause further damage if not done by a specialist with proper equipment. Hard-drive platters are coated with an extremely thin layer of non-electrostatic lubricant, so that the read-and-write head will simply glance off the surface of the platter should a collision occur. However, this head hovers mere nanometers from the platter's surface which makes a collision an acknowledged risk. my advice is to send it off to get the data recovered but be prepaired to pay a hefty bill.
