Bad cluster is typically a spot defect on the surface of the disk. Could be a small piece of dust during the plating process, a tiny bubble in the plating, a spot where the heads were bounced into contact by a sharp jolt. Lots of causes. What is important is that you shouldn't be getting more and more of them as time passes. Typically you'll mark clusters bad during the lowlevel formatting of the drive and then it'll run fine. If you're getting more and more bad clusters as time passes *BACKUP AND REPLACE THE DRIVE NOW!*

Usually a series of bad clusters becomming more and more frequent and *shortly* thereafter you have a *TOTAL CRASH*. If this is the case, BACKUP NOW!!!

There could be numerous reasons/fixes.  What operating system, format types, etc.... all important.  If Windows 98, FAT 32, this may guide you
