Quantum IDE HDD Power Saving Issues
XEN-PC 486
Drives developed prior to the standardisation of the BIOS Auto Power
Saving Function i.e.
Quantum Maverick drives with firmware A06.06.07 or
earlier.
Were not developed to support this BIOS feature.
If this option is enabled, they could potentially exhibit a problem if
the HD is AUTO powered down while carrying out a write to the drive. This problem exhibits
itself mainly in FAT errors. Drives with 06.06.07 firmware can be identified by the label
on the IDE connector.
REV 02-G indicates firmware A06.06.07 NO SUPPORT
Later drives with firmware A06.0A are designed to support the BIOS Auto
Power Saving Function and do not suffer from the potential corruption problem.
REV 03-J indicates firmware A06.0A POWER SAVING SUPPORT
To simplify field issues we recommend that the HD Auto Power Saving
Function is turned OFF in the BIOS on 486 XEN-PC systems.
If you are purchasing drives from third party suppliers, you need to
confirm that the drives conform to correct specification, before configuring the CMOS.
ENGINEERS VISITING A SITE SHOULD DISABLE THIS OPTION IN THE BIOS AS
STANDARD. |
