Thanks for ur help (: It would be more precise to use dd if=/dev/zero of=/dev/ad0 bs=512 count=1 as this will delete exactly the first block of the first IDE-disk, aka MBR. If your MBR is corrupt, but you still care for the data, you have better chances to recover this way.

RE: Hard drive geometry headache (slightly off topic)
Now I had to move it to a new computer in which the bios detects a certian geometry, but then the system wont boot. No matter what I do I had the same problem back in 4.5. I worked around the problem by formating the hard drive with a Win98(Oh Boy) recovery floppy then ... Formatting/fdisking under windows 98 or xp cd's didnt work for me, caused the same trouble.

Hard drive geometry headache (slightly off topic)
Hello! I have a problem which i cannot seem to fix no matter what I do! I have a 120GB disk, which had windows XP/FreeBSD partions working fine on one computer. Now I had to move it to a new computer in which the bios detects a certian geometry, but then the system wont boot. No matter what I do now, i cant get the system to boot off the disk, i have even tried eraseing it with fdisk (freebsd and dos versions). Does anyone know how I can save it? I have tried everything and dont know where else to ask.

I have tried everything and dont know where else to ask. Check to see that the BIOS is using the same addressing mode as the old board. I had a somewhat similar problem and it turned out the BIOS was in Large mode. Switching to LBA solved the problem. Also, if you've fdisk'ed the drive, chances are you've hosed the installations. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

I stopped caring about the data on the disk (which is backed up, so just an inconvenience. I have tried setting LBA/Large/CHS and booting and installing freebsd. Under each type, fdisk always reports that the geometry is incorect. Each time the install works fine but then when trying to boot, it cant read the hard disk! I am guessing freebsd works out the correct drive geometry, but the bios is not! Interestingly though, when set to LBA, the head/cyl/sector count is equal to what the freebsd fdisk detects it to be. (This is a new motherboard which works when booting/installing FreeBSD on an old 2G hd i have lying around) the problem is only with the 80G drive Fred ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

This is exactly what I was experiencing. Thought I'd throw that out there, best of luck to you. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
