So I’ve got an older model G Speed Q 4 TB drive (USB 2.0, FW800 and Esata) that was striped at RAID 5 that took a tumble and now is not working and I’ve had a tough time diagnosing the problem.
When it was first powered back up the notification lights for each drive showed there were no issues however the red warning LED on the casing would flash and not stop. The drive would not mount or be seen by a disk recovery software like disk warrior.
I have an second identical G Speed Q drive also 4TB that I figured could help solve the issue. I swapped out the 4 drives from the unit that fell and placed them into the functional unit - the red warning LED would also not go off on the 2nd casing for the drives either. I then placed the 4 drives that were in the functional casing into the one that fell and it started up and worked perfectly.
I believe that one or more of the drives from the unit that fell are causing the unit to not behave normally even though the status LEDs on the drives are reading as normal. My question is how should I go about figuring out which drive(s) are at fault? I contemplated getting a single replacement drive and swapping out each drive to see which one is faulty but if there is more than one, this method won’t help.
Any assistance would be greatly appreciated.
