I am helping a friend get some information off of 6 GRAID drives. The were being used with a Mac and we both have PC's. Each drive is used one per year. The last three drives we can see just fine and works the way we would like. The first 3 we cannot view at all, I can see it in the Windows Disk Manager. It shows as "Disk 7" 5589.04 GB - Not Initialized" then shows to the right 5589.04 GB Unallocated. These are 6 TB drives, I am assuming all the info we are looking there is there but I cannot view it.
I can initialize the disk, I am afraid it is going to format it and I will lose all of the info.

All drives on the PC are up to date,

I can get the property of the G-TEch drive and it says it is working properly and shows the driver up to date.

Any idea ?

Thank you

Paul
