Files that you save to a floppy disk or to a network drive
may intermittently become corrupted or damaged.
This problem may occur for either of the following reasons:
- The method that is used when Microsoft Excel reads and
Microsoft Excel uses a technique called "back seeking" when reading
and writing files. "Back seeking" means that when Microsoft Excel
opens a file and reads from it, it does not necessarily read or write
in a sequential manner. It may start at the first record in the file,
jump to the fifteenth record, go back to the third record, and so on.
This "jumping back" part may be what is causing the intermittent
corruption of files especially when you are saving to a floppy disk
drive. Microsoft Excel is one of a few programs that uses this
technique when reading and writing files. Often these disk problems
appear to exist only in Microsoft Excel. Having the floppy disk drive
heads realigned should correct this problem.
- A conflict occurs when Microsoft Windows virtualizes the
hard disk controller.

98 Startup Menu.
