Apple Drive Module shows blue activity light permanently
We bought a spare ADM together with a G5 XServe and 3 80 GB drive modules. I just inserted the spare for the first time yesterday and whenever it is in the bay, it displays the blue light. To remove it safely I shut down the XServe. The original 3 modules behave exactly as expected. Is there any explanation for this behaviour? Thanks.
How are the other three drives configured? RAID or individual drives? Are you running with three drives in the X at one time, or two drives and one empty bay? Are you trying to break a RAID or just replace a drive?
They are configured as 3 individual drives. I just swapped out one of the drives to try the spare out before we colocate the server. It doesn't matter if I install it in bay 'B' or 'C' (my start-up drive is located in drive 'A').
edit: To be clear, I have 4 modules in total. 3 are in the XServe plus the additional spare.
Yes, other than the blue light, the drive is functioning completely as normal. I have created a mirrored RAID set with it as one of the drives. I have deleted it from the RAID set. I have reformatted it as Mac OS Extended (Journaled). I have swapped it from bay to bay.
