Hello
Thank you for contacting us.
Please, be informed that disks used in Fujitsu storages, have specific firmware, adapted for continuous work. No other FWs allowed.
Therefore, if you install regular disk, even if it has the same model, disk will be marked as unsupported and can't be used.
To replace failed disk you need to buy new one from authorized Fujitsu reseller. You can do that by accessing the following page:
