I erased the SSD drive in my MacBook and was reinstalling Lion when it failed about 75% through the install. Now in Disk Utility, sometimes I see the SSD drive and sometimes I boot and it's not there but I can never erase or partition it. I get an "error 6988 couldn't unmount disk".
When I attempt to run fdisk
to correct the MBR. fdisk
doesn't do anything.
Any ideas how to fix a disk that is this severely screwed?

I can't test it but I think that if you erase the MBR (with dd instead of fdisk) and the partition table record you should be able to re-format you ssd. Boot from cd or external hd and open terminal
this code erase the MBR:
this one erase the partition table also:
If you erase just the mbr you could use testdisk to attempt to recover data (in case you don't have erased the disk label).
