Compatibility Notes - Seagate MARATHON 810 Installation Manual

18 Marathon 810 Installation Guide, February 1996

Compatibility notes

The Marathon 810 conforms to the ATA interface specifica-
tions. The host system BIOS must provide support for the ATA
interface command set. For a detailed description of the ATA
commands implemented by this drive, see the Seagate Mara-
thon 810 Product Manual and the Draft Proposed ATA-2
Standard .
In accordance with ATA specifications, the system BIOS must
reset any emulation/translation parameters after a hard reset.
In some configurations, a Marathon 810 may supply up to 16
bytes of error-correction code (ECC) with the Read Long and
Write Long commands. Depending on the drive type, your
system BIOS may look for 4 bytes of ECC. If your system
BIOS expects 4 bytes of ECC and the drive supplies a different
number of bytes, some drive diagnostic programs may fail,
typically resulting in time-out errors. Consult your computer
documentation or call your computer dealer or manufacturer
for information on configuring your computer to receive more
than 4 bytes of ECC.
Some older drive diagnostic programs may incorrectly report
an ECC-detection failure when analyzing a Marathon 810.
This occurs because the drive hardware corrects the data
automatically, avoiding the error rather than reporting it. Such
a report does not indicate a drive malfunction.
