I had a missing hard drive on a FreeBSD box that had a single IDE drive that was incorrectly jumpered. After I switched the jumper on the disk controller, everything was correctly detected by the device probe. (This shouldn't be an issue on SATA drives though.) Something you might try before looking into hardware issues, is to use a liveCD such as Freesbie (available in the ports collection sysutils/freesbie), boot to the liveCD and use dd(1) to entirely obliterate the first few sectors of the disk, nuking the the master boot record. That is, if the device probe on the liveCD detects the disk. (Perhaps use an older version.) This will make any previous data on the disk inaccessible, but if a really corrupt master boot record in concert with a funky BIOS are at fault, this would resolve the issue. You could then use sysinstall to install a new master boot record and so forth. The command would look something like this: dd if=/dev/zero of=/dev/ad0 bs=512 count=1 # Nuke the master boot record. Replace 'ad0' with the appropriate device. # IMPORTANT: This will make the disk not bootable. Just a thought. -Modulok- On 3/1/08, comperr <comperr@gmail.com> wrote: > Just to add I am using an MSI P6N SLI plat. motherboard > > On Mar 1, 10:28 pm, comperr <comp...@gmail.com> wrote: > > When I put in my fbsd 6.3 or 7.0 install disk sysinstall is unable to > > detect any of the hard drives in my computer. > > > > This is includes SATA and IDE HDDs in varying orders.
