I have a RAID 5 array on a HighPoint RocketRaid 3220 controller. There are 7 x 1 TB Seagate SATA Barracudas (ST31000340AS).
I have inadvertently sent the wrong voltages to 3 of the drives (long story) and presumably blown the electronics on them (they don't show up in the raid config any more). Obviously the data is still on the platters inside the disk.
The PCB on the drive looks like it can be unscrewed and replaced, unfortunately that model of HDD is no longer for sale. I had an 8th drive setup as a hotspare, and that disk is still fine.
I'm trying to figure out what to do next....
The most obvious option is to take the PCB off the hotspare and put it on one of the damaged drives and see if it is recognized. This will check that the motors are still ok. I'm assuming that this will be fine.
------
Questions: (even if you can just answer one or two of them it will be appreciated!)
1) If I purchase another Seagate SATA HDD will those electronics control my drive - is it hit and miss or is there some logic that can be applied as to what to get for my drives?
2) Is there somewhere I can just purchase the electronic controller PCB?
3) Has anyone got any experience with this sort of problem?
4) Is the firmware for the on-board electronics of the drive stored in the chips or is there some sort of record of how the controller should read data off the drive stored on the actual platters / off the PCB?
5) How does the RAID controller identify a disk
6) If I mirror a drive is there a way to transfer the info the controller uses to identify a disk onto a new one?
I know that there are specialist services centers (including one operated by Seagate), I'm trying to avoid using them.
*** please only answer if you actually know something or if you are making assumptions please note them - I'm *not* looking for script kiddie level answers ***
TIA
