SubjectRe: Warning - Maxtor SATA II and Nvidia nforce4

Ah, I see this made it to LKML :)

I'm a bit suspicious of this.

Looking at the link, there are three problem areas and two problem blame
targets implied:

Data corruption -> blame nvidia driver
NCQ -> blame nvidia driver
Detection -> blame maxtor firmware

The first one likely applies to the Windows driver not Linux's sata_nv,
and thus irrelevant here. The second one OBVIOUSLY applies only to
Windows, since sata_nv (and libata itself) don't yet enable NCQ. The
third one could potentially apply to Linux. Lastly, your mention of
"nforce fake raid" almost certainly indicates Windows or proprietary
drivers.

Therefore, I ask:
* are you reporting a only drive detection problem?
* why are you reporting unrelated Windows problems to a Linux list?
* if you are indeed reporting a problem on Linux, where is the kernel
and driver version info, as requested in REPORTING-BUGS?
* and can you provide such info *and reproduce the problems* without
proprietary drivers loaded?

Your email is just a list of highly general symptoms. Your link seems
to indicate two NV driver bugs on Windows, and a Maxtor firmware upgrade
for undescribed detection problems.

My recommended action for users is:
1) Avoid Windows.
2) Don't panic.
