I need help from someone who is an expert in RAID configurations and troubleshooting.
I have an IT company and am ashamed that I don't know more about RAID than I do. (please don't kick me while I'm a little down)
I have a customer that brought me his computer and external storage device because he couldn't access any of the data on the device after he upgraded a driver on his computer. Here is the equipment:
G-Speed ES external RAID storage device
link - G-SPEED eS - External RAID and JBOD Up to 12TB | G-Technology
HighPoint RocketRAID 2314 controller card
link - HighPoint-RocketRAID 2314
He has 4 X 3TB Hitachi drives in the G-Speed ES configured to RAID 0 for a total of a 12TB of storage.
When he brought the equipment to me, I uninstalled the RAID controller drivers and reinstalled them. When I reconnected the G-Speed, I did not connect it to the RocketRAID (which has the port multiplier technology). I instead connected it to the onboard eSATA. I went to Disk Management in the Control Panel (he has Vista), and a window popped up telling me "You must initialize a disk before Logical Disk Manager can access it." I wasn't thinking, and chose "OK". Then, Vista initialized the disk with a MBR partition and the disk began showing up in Disk Management as 3TB of Unallocated Space.
I figured out that it needed to be plugged into the RocketRAID, but now when I plug it into the RocketRAID, the whole 12TB (actually about 11.2TB) is showing up in Disk Management as one drive with 12TB Unallocated Space.
It's a weird configuration to me, not the typical RAID setup. One eSATA cable connects from the G-Speed to the RocketRAID card, almost like a USB hub would connect and show multiple devices. When the one eSATA cable is connected, nothing shows up in My Computer, but as I stated above, the entire 12TB shows up in Disk Management as Unallocated.
I would appreciate any help from techs that know what they are doing with this. PLEASE do not just start throwing out things to try. I really need someone who is a genius at working with RAID and even the Port Multiplier technology, which I haven't seen before.
Thanks in advance!
