Is this a SCSI disk?
I had this same problem last night, it turned out to be a bad SCSI cable.
The disks were found on boot and the SCSI bios could see them on the chain
but when it tried to boot it kept saying no disk found. I booted a DOS
disk with fdisk and it also couldn't see the disk. I almost trashed the
drive. On a whim I replaced the cable and it everything worked. It turns
out the scsi cable had a bad active terminator. I replaced the cable and
everything came back.
If your system is scsi, it's something to try anyway.

normally and displayed 'F? FreeBSD', but as I struck 'enter' I got a 'boot
failed' message. Then I rebooted the machine again and started getting 'No
operating system found' messages. I thought that maybe the boot record had
been damaged so I booted the FreeBSD 4.6-install CD and opened fdisk - all
space unused, no partitions found. No sign of my data at all!
Get your disk back from Dell.
Then try testdisk or gpart.
