Error Message Running Jet Database Engine Stress Test

Q154976

The information in this article applies to:

Microsoft Windows 95

SYMPTOMS

When you are running a program that causes a large number of writes to occur very rapidly to an IDE drive, you may receive the following error message on a blue screen:

Disk Write Error
Unable to write to disk in drive <x>:
Data or files may be lost

You may be able to recover from this error by pressing a key to remove the error message and retry the write. The operation typically continues, although additional errors may occur until the operation is finished.

CAUSE

If a program generates a large number of disk writes very quickly, a timing problem involving the IDE disk driver and the cache may occur, resulting in the error message.

This symptom has been reported to occur with a hard disk stress test using the Microsoft Jet database engine that is included with the current versions of Microsoft Visual Basic, Microsoft Office, and Microsoft Access.
