If you cannot tell which device is experiencing difficulties, reduce the
synchronous transfer rate for each device separately to see if the
problem is resolved.
•
Disable disconnects for the problem device. Communication between
the driver and the device may not be accurate if the device is allowed
to disconnect from the bus during an I/O transfer. If available, use the
SCSI BIOS Configuration Utility provided with some members of the
LSI Logic family of host adapters to disable disconnects. Refer to the
PCI Storage Device Management System SDMS 4.0 User's Guide
for the availability and use of the SCSI BIOS Configuration Utility. If
the SCSI BIOS Configuration Utility is not provided with your host
adapter, use the command line option
as described
in the Command Line Options section above.
If you cannot tell which device is experiencing difficulties, disable
disconnects for each device separately to see if the problem is
resolved.
•
Back up your data and perform a low-level format on the problem
device. You may be attempting to read from or write to a bad sector
on your device.
Note:
Low-level formatting will completely and irreversibly erase
all data on the device. It will default the drive to a 512-byte
sector size even if the drive had previously been formatted
with another sector size.
