Recovering Detectable Files Despite Cyclic Redundancy Check

February 19th, 2015, 5:16

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 drive 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?

If you want to attempt a do-it-yourself fix you can start by checking with mhdd if the drive id correctly and if you can scan it.


The drive is an Imation Apollo one. The data is critical (family photos etc), and I'd rather try myself before going to a professional who would be quite expensive.

I'll have a look using MHDD. Thanks

What do you consider expensive...with current CAN/US exchange rate, it likely is less than $300 for this recovery. If you "try" everything you can first and then go to a pro, you could cause enough damage it will be expensive...or, at the very least, a lower percentage of files recovered.

If you are going to do anything at all, you should be getting a full sector-by-sector clone to a blank healthy drive first.

Those two statements don't match, IMHO.
