External Hard Disk Problem

by el karel / September 26, 2006 6:39 AM PDT

I've had an external 120 Gb Maxtor Hard Disk for almost 3 years. Until recently it worked fine, but now when I try accesing certain folders I get the following message: "F:/.../(Folder path) is not accesible. The request could not be performed because of an I/O device error".
I tried backing up all the data I had onto another hard disk, but the folders I couldn't access in the hard disk of origin were copyied to the other one as empty folders. Does anyone know if this is a hardware problem and how to fix it, or if there're good data recovery softwares that could be used? Thanks.

Zero Assumption Recovery.

If that shows it then it's just the decision process if the files are worth saving.

Try checkdisk

Start by running a checkdisk on it -- it's possible that you've got bad sectors, and if anything can fix it, checkdisk is your best (free) chance.

Go to Start, select Run, and type in this:

chkdsk f: /r

The /r tells it to check the entire drive for physical problems, and try to recover any data it can. This can salvage a surprising number of bad situations, but it's not a cure-all.

Don't be surprised if you end up with a ton of files moved to the root directory with weird names -- if there's data corruption, that's normal behavior. You might be able to recover data out of those files, particuarly if they're word processing files, but often they are just fragments of the original and aren't useful.

Good luck!

More importantly with checkdisk....

...is that it will allow those directories (and any other files) to be read correctly without errors. If files are corrupted, then the data is already gone. You just want to be able to get into the directories and read whatever data is left.

Could be This

I recentily had a similar frustration.

i was unziping rar archives though, and ones they got to extraction certain files it would stop and an error would come up along the lines of what your getting but it said something about 'filename to long' and i later learned that by filename it ment the whole thing like d:/dir/dir/dir/dir/dir/dir/dir/, all i did was extract the rars directing to the d:/ and it all went fine. Then you just cut all the directorys down and cut and past it where you want the files to go.

when i came over this, i thought id have to find recovery software and leave it running for a day or two.
