Does it still show as connected during the post messages at boot up or in 
the bios?  It's possible it could be a hardware fault or maybe the 
connector(s) worked loose over time? Can you read disks otherwise? If 
dual booting does another OS read the disks? Also might help to know 
your hardware setup
