6. What are some common troubleshooting steps?
-
Make sure the cable is Ultra ATA/66 capable. An Ultra ATA/66-
capable cable is a 40-pin, 80-conductor cable with a black connector
on one end, a blue connector on the other end and a gray connector
in the middle. In addition, line 34 on the cable should be notched or
cut (this may be difficult to see with the human eye).
-
Make sure the system board is capable of Ultra ATA/66. An Ultra
ATA/66 capable system board has a detect circuit with a capacitor for
detecting line 34 missing on the cable. If there is no capacitor, the
system can wrongly detect the presence of an Ultra ATA/66 cable
and therefore try to configure the device for a higher transfer rate.
-
Some system boards may not successfully handle Ultra ATA/66 on
both ATA (IDE) channels. If you have difficulty, consider
troubleshooting with the device in the Primary Master position.
-
Contact the system board manufacturer for the latest BIOS upgrade
and any Ultra ATA/66 special device drivers or patches.
-
Make sure the operating system is DMA capable and that the DMA
mode is activated. (For Windows 95/98, check Device Manager |
Drive Settings tab for a check box.)
-
Make sure the drive is Ultra ATA/66 capable and has been
configured to run at Ultra ATA/66 transfer rates. (Seagate drives
require an Ultra ATA/66 activation utility.)
