Does any body have Segate drive ST380021A working with FreeBSD?
Does any body have problems with it running 5.2-5.current or other
versions of FreeBSD?
Best regards,

Hi,
I have some problems with my HDD (ST380021A). The problem was
checked on 5.2, 5.2.1, and some
5.Current (cvsuped about week or two).
At first I got this problem while system installation. I get trap
and message from ata after I start a commit:
FAILURE READ_DMA status=51 error=10
LBA=245529601
If I read the above modelnumber correctly it is a 80G disk..
There is only ~16000 sectors on such a disk, so you cant expect
to read sector 245529601 as its not there :)
I know that, and this is the problem. I am trying to read 41929650,
but system thinks this is 245529601.
This sector is near 20G mark, so I tried to read it from 40G disk,
which I use to run fbsd. All is fine.
Now why sysinstall tries to do that is beyond me, but could be a
problem with the geometry (it seems to always get it wrong these days).
This is not a problem of sysinstall at all. As I wrote, it is enougth
to try to read one sector. So this problem
somewhere between read call and ata driver. This area wasn't in focus
of my interest before, so I don't
know where to go.
Also, I tryied to read some sectors back and forward, and found out
that value of LBA changes nolinear.
Lower byte is linear only on interval of 63 values, so I gues this is
a sector value. And it seems that LBA value
not LBA value at all :-(
This is all I have now. Any ideas, comments?
