Hello John,
With the system running if I insert the new disk the drive light does not turn green. If it powers up I cannot really tell, being in a server room w/fans and A/C it is hard to tell....I tested the port by moving one of the working disks into it, and yes, it powers up and turns green (then rebuilds the disk because its Raid 5).
I did check the Tested Hardware list, the disk is not specifically on it, however the make, model, p/n lead me to believe that they might fall into the Similar Drive category. I am having a hard time finding disks on the tested list because they seem to be no longer available. I know these disks may not work in the long run, however I would dearly love to have someone tell me how to format the disk so I can be certain that it isn't working BECAUSE the disk won't work, not because its formatted incorrectly.
