.SH "DESCRIPTION"
.PP
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\&.
.PP
For certain Seagate devices, we must limit the maximum sectors to under 8K\&.
.PP
For certain Maxtor devices, we must not program the drive beyond udma5\&.
.PP
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\&.
.PP
20040111 \- Seagate drives affected by the Mod15Write bug are blacklisted The Maxtor quirk is in the blacklist, but I\*(Aqm 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
