4TB HDD help!

[discodancepant]

I made a mistake and initialized my 4TB HDD without putting it in RAID first. The hard drive in now sepperated into two partitions, one 2TB and one about 1.6TB (so it's not a full 4TB I guess)

The format was MBR. I tried converting the partition to GPT, but it still only shows either the 2TB or the 1.6TB in bootable partitioning tools. I tried changing to raid, but with the single HDD installed, the RAID array creation menu doesn't even appear.

Does anyone have any ideas of what I should try next? Or have i botched a perfectly good 4TB HDD?

No, delete both partitions and see if the RAID will take it raw, if not reformat it as GPT.

THe 'loss' of drive space isn't a real loss. YOu bought a 4TB drive, that is ~4,000,000,000,000 bytes of storage space. Since the computer counts binary instead of decimal, that doesn't quite equal 4TiB.

When I attempt to reformat, it only sees either the 2TB or the 1.6TB, it never shows both. When i convert to GPT, it still says only the 2TB or the 1.6TB, hiding the other.

When i reboot, the RAID manager screen doesn't even come up unless I install a second hard drive. When i configure a RAID array with the new second hard drive (1.5TB) it will only grant me 3TB total.

No, delete the partitions through disk management first. If you just try to format from the My Computer window, it leaves the partitions alone.

not all motherbds support drives larger than 2tb (2.2tb technically). Please check your manufactuers website. They may have a bios or utility to enable some support.
