Recovering Detectable Files Despite Cyclic Redundancy Check (RAW Drive)

I'm one of those people who always knew I should be backing up my data, but never got myself to do it! However I have now finally started to do so and am going through each of my hard drives, one by one. Unfortunately it seems that I didn't get to one of them fast enough and it appears to have failed.

The good thing is that, using Recuva, I can see many of my files, despite a file directory that seems to have become somewhat corrupted. The bad part is that when I try recovering the files, I am faced with a cyclic redundancy check. The file is a RAW one and thus I can't use the CHKDSK /R or /F solution.

I've also tried switching to a 3rd party enclosure, but that hasn't solved the problem.

Any ideas on how I can recover my data?
 
Hey SeaTan. You could try accessing the drive via Linux Live CD/USB to see if you're able to recover your files this way, without using any data recovery software. On the other hand if this doesn't work, then you could try some of the other solutions listed in this thread here: http://www.tomshardware.co.uk/forum/id-1644496/lost-data-recovery.html
You could always try the drive with a different computer or at least a different SATA cable to see if the same thing happens and if the connection is at fault.

Hopefully one of them works for you. Good luck.

Thanks.
I've actually tried a 3rd party enclosure and a different cable, and this is how I have been able to use Recuva to view the files. However as noted, I can't seem to recover them in this way due to the cyclic redundancy check.
The link you posted in essence recommends Recuva, which is what I have used.
I'll try the Linux USB option though. Would that bypass the cyclic redundancy check error?
 
Well it's worth the try. Linux Live USB/CD is basically a portable, bootable, freeware Linux based OS, which can often help in situations like this (and lot more other stuff, but this is irrelevant to the subject) when Windows has trouble accessing a damaged partition and it appears as RAW for example. Hopefully you'll be able to get your data this way, although it's not like it is 100% guaranteed, but you have nothing to lose from trying it out.
As for the link to the thread, I know that Recuva is one of the options there, but you might try some of the others listed, as well.
Otherwise, the most reliable option is always a professional solution such as a data recovery company, but that could often prove to be quite costly. :(

Are there any particular Linux Live USBs that you would recommend?

If your hard drive is a 3.0, plug it in to a 2.0 hub. If your drive had a password tool on it, google the name of the password software and download it. Once downloaded, it'll reboot. Your drive and the password prompt should come up like it used to! It's contents should be there. I don't know how to make it work yet with a 3.0 hub again, but at least I recovered it. I'm no tech guy, but I had the same exact problem and this worked for me. I hope it helps!
