Can't read External Hard Drive anymore!

"If the data is marked as RAW, the data & filesystem itself is probably corrupt. You will need special tools to try and read the data.

Data Recovery Wizard will work for this, but it costs a fair bit. Just make sure you do not try and write anything to do the disk or reformat it. After it is written over once, you will lose your data.

Worst case scenario you will have to pay some data recovery experts to work their magic."

DiskDigger is a data recovery program that is small, portable, easy to use and above all free, unlike 99% of these kinds of applications out there, try it.

External drive in a USB enclosure? USB fails more often than the drives do. Try another computer, then another enclosure. Finally, (or if no other enclosure available), put the drive in the computer, like everyone else suggests.

"I've used GetDataBack, with great results in the past: it's free to try an see if it will recover anything, and relatively cheap ($79) if it looks like it will recover what you need.

One tip: you tend to have better chance of recovery if you remove the bare drive from its USB enclosure and plug it in directly to a spare IDE/SATA port on your PC."
