  • Boot disk greater than 2 TB in Windows 2008

    I stuffed up when I set up a machine with Windows 2008. This machine has 8 x 1TB drives in raid 6. When I installed Windows 2008 I set it on a 100GB partition. When I got into the OS I created a data volume of ~2TB as that was all it let me pick. There was ~3.5TB left of unallocated space that I thought I could allocate at any time in the future.

    I started installing all sorts of software onto this machine and now, 1 month later, I want to set up the remaining space. It appears that this space is actually inaccessible to me. I have read that the boot MBR disk has a maximum allocation size of 2TB.

    I am wondering what is the quickest way to access this space while, hopefully, maintaining my data. My last possible resort, at this point, is to back up everything and rebuild array so that I have one for data and one for booting (if this is even possible). Hopefully it doesn't come to that.

    Change the parition to a GPT parition from computer management. For that though you may have to delete the entire logical disc.

        I have read some of this information, but it doesn't appear to help in this particular case exactly. I have just one disk with 2 partitions and some unallocated space. This disk is ~5.5TB with one boot partition ~100GB, one data partition ~1.9TB, ~3.5TB unallocated space. According to the link I can only convert to GPT if there is no allocated space. Since I boot from this I see no way to go this route without wiping everything.

        Is it possible to convert the disk to GPT without Windows installed? This may save me from having to recreate my arrays, but I still have to deal with backing up, wiping and restoring everything. I guess there is no other hope?

          Just to make sure I have this correct, do you have the operating system on the RAID 6 volume?
          1 1 was a racehorse.
          2 2 was 1 2.
          1 1 1 1 race 1 day,
          2 2 1 1 2

            Yes, everything on that machine is on the RAID 6 volume. I took 8x1TB disks and made them into one RAID 6 volume. From there I created a 100GB partition for system/OS files. Once in Windows I created a 2TB data partition. 1 month later I tried to allocate the remaining 3.5TB only to end up here.
