SCSI Drives Using FAT32 Should Be Repartitioned When Moved (153548)
The information in this article applies to:
This article was previously published under Q153548 SYMPTOMS
After you move a SCSI hard disk formatted with the FAT32 file system from
one SCSI controller to another controller, you may not be able to reliably
write data to and read data from the hard disk.
CAUSE
This behavior can occur if you partition and format a hard disk using a
SCSI controller that fully supports interrupt 13 extensions and you then
move the hard disk to a controller that does not fully support the
interrupt 13 extensions.
RESOLUTION
To move a drive using the FAT32 file system to a different controller, you
must verify that both controllers fully support interrupt 13 extensions in
the same manner. If they do not, data loss may occur.
Microsoft only supports the use of fixed media on the same controller used
to partition and format the media.
NOTE: This information does not apply to removable media.
MORE INFORMATION
Windows 95 uses logical block addressing (LBA) on most SCSI drives to
access data. With drives using the FAT32 file system with interrupt 13
extensions, Windows 95 depends on the BIOS to fully support the interrupt
13 extensions.
This problem typically occurs only with drives 8 gigabytes and larger
in size.
