Everytime I start my empeg I get building music databases, it takes about 30 seconds for it to go through it. Ive tried doin what the site says for manually building the database to fix it. But it still does the same thing. When i try to sync in emplode it goes to checking media for a while, then rebuilding datase for a while then it finishes that and then emplode crashes.

Did you do an FSCK ? (sub-linked from the database rebuild FAQ)

Yea i did a fsck. Then i tried the cat /dev/zero > /dev/hda4 . That errored out , and how the drive is coming up hard disk not found. The drives dont even spin up. So im suspecting bad cable.
