Dear Sirs, I am looking for some support or advice please.
We have a G-SPEED es which is setup as Raid 5 setup for Mac OSx 10.11
They have had a disk failure on disk 4. To our amazement the drives for this device were no longer available. We were advised to purchase a 3 TB HST Enterprise drive for a similar / newer G-Technology model which we have done.
We have replace the drive in the unit and were expecting the raid to start rebuilding the replacement disk but it did not. The drive appears in the list under the raid utilty with a small arrow next to it. Also when the replacement drive was inserted into the G-Speed ES, the Mac warned that the disk was not formatted. The G-SPEED also confirms this that it is not formatted. Should the single drive be formatted first (on the mac side using disk utlity) before it is recognized by the g-speed raid utility and then the rebuild will take place?
Any advice would be gratefully welcome.
