A. What's your hardware configuration. (Controller, drives, etc)
B. Stupid question - does F6 even recognize your storage; Can you see

log? /sys/bus/scsi/devices/? /sys/bus/ide/devices/?
(Don't forget that the rescue CD is based on a far older kernel.)
C. Have you tried F7/8 rescue CDs?
D. What does pvscan return?
