Cannot use drives >2Tb in Server 2008 R2
Posted on 2014-01-23
I have an Asus Motherboard with 6 x 3Tb SATA drives connected and onboard RAID enabled. 4 drives are RAID 10 = 6Tb and 2 drives are RAID 1=3Tb
In Disk Management I cannot seem to do anything with the larger drive as it has all options greyed out.
Disk 0 (5589Gb) has 100Mb System Reserved partition, 2047Gb unallocated and 3541Gb unallocated.
Disk 1 (2794) has 2058Gb Drive C: and 746Gb unallocated.
If i right click on the Disk label Disk 0 I just get properties and help, everything else is greyed out. On the disk 0, 2047 partition I only have the option to create a new simple volume, which if i do then once formatted i dont have the option to extend the volume, it appears i can do nothing with the 3541Gb partition at all.
Again, if I right click on the Disk 1 label everything is greyed out, and if i try and extend the C: drive it appears to work and then gives the error message: "Only the first 2Tb are usable on large MBR disks. Cannot create partitions beyond the 2Tb mark, nor convert the disk to dynamic."
I'd like each disk to use the whole partition but cannot work out how to.
I tried using partition magic but got the error that the drives are unsupported when i open it up, i assume this is because theyre using the RAID controller on the motherboard, or they are simply too big for that too.
As i'm wanting to backup some very large VMDK files I need to make use of all the space so need to come up with a solution.
