engineerguy3809,

Interesting. Can TeraByte Support comment on whether the following is OK?

A WinXP system. In BIBM I converted the third internal HD to a GPT disk and created two partitions. Booted into WinXP and as expected the partitions weren't seen. But IFW could see the partitions and I imaged the WinXP partition to the first GPT partition.

Booted into a WinPE and all partitions were seen.

Booted into IFL and all partitions were seen. I restored the image I just created and all went well.

Very instructive.

engineerguy3809,

use discwizard to partition your drive.
First, assign the full capacity of 2tb and partition it according to your needs.
-important: create only primary partitions.
Then you can use it to partition your remaining 0,73tb of unallocated space. (same as before use only primary partitions).

This procedure will create a gpt disk with a protective hybrid mbr. GPT aware programs and OSes will have access to all the partitions of the disk but legacy Oses and programs will have access only on the partitions in the first 2tb.

After that you can remove diskwizard and you'll continue to have access at the first 2tb but not at the rest.

And since IFW can see and access the partitions in those 0,73tb outside the mbr, you won't have any problem utilizing all your disk.Just use that space to create the images.

Pay attention to not change the disk layout with any other partition tools (only use diskwizard), because the layout of the structure in the 2tb zone should be identical in the hybrid mbr and in the gpt.

The version of Windows you have is wrapping at 2TiB. If you want to use
the 2TiB and forget about the 1TiB then just use BIBM to create a 2TiB (max
partition size it allows) and use that or if you wanted to, after creating
that partition so you're sure it's size is correct, convert to GPT , create
another partition for the rest of the disk (won't be usable with your
current version of windows) and then click View MBR and insert the partition
you want visible to XP under the existing one that is in there.

Thanks for the reply but can you clarify the situation a bit for me? Within
Windows XP, I did attempt to create two partitions of about 1.5TB in order
to stay belopw the 2.2TB maximum. However, Windows insisted the physical
drive was limited to about 746GB in size and did not display any
unpartitioned or unused space beyond that. I then looked at the drive using
PartED/Linux and I can easily partition & format accordingly. As such, I
know the drive is not defective. Next, I created & formated two NTFS
partitions of about 1.5 TB using PartEd. However, when I restart XP and
looked at the drive, XP still insists it can only "see" a maximum usable
space of 746 GB and nothing beyond that. Can you further clarify what I'm
missing and what I need to do?
