I have a portable hard drive that is experiencing some disk errors. When I try to copy certain files. I GET a CRC error. I'm trying to run chkdsk /R /X on the drive but it says "cannot lock current drive Volume dismounted. all open handles to this volume are now invalid" then it started the check, but remains at 0% complete. it's a 300GB WD hard drive. is it just slow? or is there something wrong? what else can I do to NOT lose this drive. I cannot afford a new one.PS. The check is at 26% So I guess it is slow. but I still want to save the HD...Run chkdsk /r without the "x" switch and see if that works. If that doesn't work download and run the hd utility from the drive manufacturer's website.Aight! Thanks! It's running it right Now. So if they doesn't work, I'll try it without /X! You rarely need any switch BESIDE the /r switch. I only suggested not USING the /x switch because of the "handles" message you got. But if it's running that's fine.thx. so the chkdsk finished. what exactly am I looking for? is completed. this is what I got.

and during the check, it named some of the files I was having the CRC error with, it said "Windows replaced bad clusters in file "...File name..." of name (null)...
so can anyone translate? did this fix it? or did it just confirm the bad spotsCheckdisk found areas of the hd that the File Table thinks are occupied but really are not (bad clusters) and fixed them. This problem is generally caused by anomalous shutdowns (turning off the system with the power button instead of allowing it to shut down properly). This will often cause LOST clusters, bad clusters, or other software issues. It is not generally a disc problem per se.So I shouldn't be worried unless it gets worse? Right. You might want to run chkdsk /r on the drive once more when you have time, just to make sure it got everything (sometimes the second time through something else may come up). Or you can download and run the hd utility from the hd manufacturer's website.
