Disk not detected in ReadyNAS 4220
Hoping someone could help me out. We have a ReadyNAS 4220 which had a failed disk, we have replaced the disk but it is not being detected. The web interface just shows a empty slot. I have rebooted t...
The drive was replaced whilst powered on, we did the same for another failed disk on Friday and that one worked fine. We have tested with another new disk and that one is also not detected, the bay is showing empty under Volumes and not disk showing under performance in the GUI. I will see if we have a dock to test the disk and go from there.
Two unrecognized drives does not bode well for the slot. They are SATA drives, not SAS, right? I don't recall if the 4220 will physically accept a SAS drive, but it definately can't handle them. Check to see that there doesn't seem to be any damage to the SATA connector or debris in it. And while you are checking the new drive, check the old one. If it's actually good, then that's a very bad sign with regard to the slot itself.
Yep both SATA disks, connectors have all been checked and no signs of any damage, dust or debris. Got the new disk be shipped to our office for testing and getting quotes for a new NAS.
