I'm dual booting WinXP 32-bit and Win7 64-bit. I have another computer running Win7 32-bit. I have two 3TB internal storage drives and want to be able to use them from my WinXP 32-bit install also. I used the "Paragon GPT Disk Manager" to make the 3TB drives viewable on the Win7 32-bit machine in the past and had no problem. It worked great and I could use the entire 3TB. When I ran the program on XP and choose to convert the drive to GPT it shows all my drives but the 2 3TB ones are greyed out! Very weird, so I checked device manager and they showed up there. Then I looked in disk manager and they don't show up there! It's crazy. It just skips Drives 1 and 2. There's not even a space for them. It goes from Disk 0 to Disk 3. I can use the paragon software to format the 3TB drive, but it's still greyed out when I go to convert it and still not in disk management. Please advise.

Well the limitation is the a 3TB drive cannot have a partition and can only be used as a secondary drive under Windows XP.

I'm not sure what you're saying. I'm not trying to boot off of the drive and I've already made an entire 3tb drive readable (with 1 partition) under a 32bit Windows OS by using that Paragon GPT Disk Manager software. But either way I can't see it in Disk Management to even try to make it into 2 1.5 partitions (which I don't want to do anyway)

So you cannot see this disk in XP correct?

GPT disks are supported only by Windows XP 64-Bit Edition. You cannot move GPT disks to computers running the 32-bit versions of Windows XP. From Disk Management on computers running a 32-bit version of Windows XP, GPT disks appear as basic MBR disks with a single partition covering the whole disk, but the data on the partition cannot be accessed.
