Hello,

I'm hitting some problems with a Toshiba drive (MK3263GSX).=20


When I boot from a cd during installation, it installs on it fine, and =
there are no issues or errors on the consoles.
When it comes to booting from the drive, it's geometry is detected as 0 =
sectors, 0 heads, 0 cylynders, 0 mb and of course failts to boot. =
(Geometry during install is correct). If I then boot off a cd or usb and =
mount the drive, it works just fine, and everything from the =
installation is on it, similarly copy to/from the drive is fine as well.

I've had other OS installed on the drive (same system) no problem, and =
it seems it's only having issues on FreeBSD during boot. Any ideas, =
pointers? I don't know if it makes any difference, but the CD I install =
from is a USB cdrom. I've also tried playing with ata timeouts, but it =
didn't seem to help. There is no raid involved. I have two machines like =
this, and both behave identically.

The errors from dmesg during boot are:
ad0: 0MB <TOSHIBA MK3263GSX FG020A> at ata0-master SATA150
ad0: FAILURE - READ_DMA48 status=3D51<READY,DSC,ERROR> =
