Bad Clusters

By lazybedstar23 ·

I am using an external Western Digital 160GB Hard Drive to store all my data. Recently I have had a few problems editing one or two files (out of thousands) that were stored on that drive. The app would hang and crash when trying to save.

Today, when i plugged in the USB Drive, instead of seeing the name of my drive in explorer, i see "Local Disk (K:)" and the drive could not be browsed. Said the disk is NOT FORMATTED! So I ran a chkdsk /f /r on it. It DID repair the problem but in the process it did report having about 20 bad clusters. Is this normal? I notice that some of the files I could not edit were actually on BAD CLUSTERS when running the chkdsk.

Does this mean i got a shot drive??? Its pretty much brand new. Also, i do carry it around alot, could physical damage cause this? It seems like a file system error, but i am not sure. Does Bad Cluster mean physical hardware issue? Could i have banged it around too much or something? Are the bad clusters normal?

yes, yes, yes, yes, & no, bad clusters are not normal.

you CAN mark those bad clusters so that Windows will not attempt to write data to them, but that's not to day Windows won't, it might, but eventually with enough banging around the amount of bad clusters and sectors will grow to where your data loss on directories, subdirectories & files is enough to drive you nuts & you might as well just get a new dirve.

D.R. is correct. Yes, you can have Windows not write to those bad clusters, but once clusters have started going bad, chances are likely that more bad clusters will be coming. It is indeed hardware, but if you don't abuse your CPU, it's probably just a part of the drive that has begun to fail such as the arm that moves the read head. In any case, the most important thing for you to do is to back up or rescue your important data ASAP and make plans for a replacement on your time, not when it's a crisis. Your drive is failing and you need to get your data off of it now.
Good luck!

Agreed with the above answers but you should ensure you have a safe way of transporting your drive before replacing it and going through the same thing again.

MANY hard drives will coem with a special carrying case, if your's didn't do out and buy one, just a small case like a camera case shoud do for toting it around and reducing the shock.

if in your car, be sure it is not in a place subject to heat or excessive vibration, again this is reduced by using an additional case for you HD even if stored in your computers carry case, double bag it just to be sure.

why don't you download and run the diagnostics from western digital on the drive. if it can be fixed (that is, if the bad sectors can be blocked out, the diagnostics will tell you and do it. if the drive shows lots of bad spots, you'll need to do this for warranty replacement anyway...www.westerndigital.com
