Hi!

I've got a Dell Media Bay which seems to be very similar. For me it only
works after rebooting or after resuming from hibernate. Have you already
tried to unmount it, then simply exchange them?

What kind of SATA-controller do you have? If you have to use the Intel
driver (look into your bios if you can use AHCI instead), you might want
to play with "ata_piix.force_pcs=x" kernel parameter (if its a module,
load it with "force_pcs=x" as a parameter). x can be 0,1 or 2. Neither
works for me.

Look here: http://linux-ata.org/driver-status.html

As usually: I'm not responsible if you break your hardware/filesystems
when following my advices.
