I have a Drobo connected via Firewire to my MBP which is causing me some issues. Here is the diskutil info:
Device Identifier: disk2s2 Device Node: /dev/disk2s2 Whole: No Part of Whole: disk2 Device / Media Name: MacDrobo Volume Name: Mac Drobo Mounted: No File System Personality: HFS+ Type (Bundle): hfs Name (User Visible): Mac OS Extended Journal: Unknown (not mounted) Owners: Disabled Partition Type: Apple_HFS OS Can Be Installed: No Media Type: Generic Protocol: FireWire SMART Status: Not Supported Volume UUID: A97C9EAF-E18F-3BE3-80CD-8A8C6FB6E8E7 Disk / Partition UUID: 3776B4B3-8530-495E-A413-AFB0A221281B Total Size: 2.2 TB (2200000000000 Bytes) (exactly 4296875000 512-Byte-Units) Volume Free Space: 0 B (0 Bytes) (exactly 0 512-Byte-Units) Device Block Size: 512 Bytes Read-Only Media: No Read-Only Volume: Not applicable (not mounted) Device Location: External Removable Media: No
It is not mounted but it is still very active in reading and writing...I can hear it thrashing about. When I try to eject or mount I get time out errors, when I try to run verifyVolume, I get a bit more of a complex error.

I assume my computer is doing something in the background as when I unplug the drive it stops being active, and becomes active again when I plug it back in. I have tried using Disk Utility to see what is up but if the drive is plugged in then DU never loads completely, if its open then I plug in the drive nothing shows up. Is there any way to see what is going on with the drive, if OS X is fixing it in the background, or what is going on?
