Error Message Running Jet Database Engine Stress Test

 Last reviewed: November 26, 1997
Article ID: 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.
