Even worse, a repair program will have a hard time reconstructing damaged files if the drive is fragmented. Windows 95 comes with a serviceable if unspectacular defragmenting utility. It takes longer, but you don't have to sit and watch it. Start it when you quit for the night, and it will be done before you return in the morning. Scan your disk .
Bad things can happen to even the best hard drives.
Parts of long file names can be orphaned if you use 16-bit applications. The operating system can lose track of files, and wear and tear can render sections of the drive unfit for holding data. A good scanning utility checks for these errors and corrects them. But every couple of weeks or so, you should do a more time-consuming full scan of all drive partitions.
