I have a dataTale 2-bay Firewire 800 enclosure It's worked fine for a few years but just recently it's been unmounting; both disks are not visible in the Finder. They are visible in Disk Utility but unmounted. If I click mount, they don't mount The dataTale is directly attached to a Mac mini which is always on. I typically access the drives over the network from a MBP. The disks are configured as JBOD - no RAID There's also a FW400 drive daisy chained to the back of the dataTale (i.e. mini > dataTale > FW400) and it stays mounted even when the dataTale drops its drives What on earth is going on & how can I fix this .. any ideas?
