After the IDENTIFY [PACKET] DEVICE step is complete, and a
device is known to be present, this function is called.
We apply two errata fixups which are specific to Silicon Image,
a Seagate and a Maxtor fixup.
</p><p>
For certain Seagate devices, we must limit the maximum sectors
to under 8K.
</p><p>
For certain Maxtor devices, we must not program the drive
beyond udma5.
</p><p>
Both fixups are unfairly pessimistic. As soon as I get more
information on these errata, I will create a more exhaustive
list, and apply the fixups to only the specific
devices/hosts/firmwares that need it.
</p><p>
20040111 - Seagate drives affected by the Mod15Write bug are blacklisted
The Maxtor quirk is in the blacklist, but I'm keeping the original
pessimistic fix for the following reasons...
- There seems to be less info on it, only one device gleaned off the
Windows driver, maybe only one is affected. More info would be greatly
appreciated.
- But then again UDMA5 is hardly anything to complain about
