Does anyone know of a tool that can recover GPT? I have a 16-drive RAID system that has two partitions. Due to an unrelated issue, I was trying to resize the GPT partition, and used diskpart before discovering it did not work with GPT. This caused the extra space to no longer be available at all. In trying to fix that, I used a different tool, which seems to have executed the Clean command of diskpart! Needless to say, my two drives no longer show in Windows. As mentioned above, the RAID volume is partitioned into two drives. One is 703.13 GB, and the other contains the remaining space, which is 13-14 TB in space, depending on if the actual expansion worked with the tool that ruined everything. Any help? Unfortunately, I don't have anywhere else I can put all the data (it's too much for any other disks or media I have). Therefore, I can't use a "recovery" tool. I need something that will rebuild, discover, repair, or whatever the record so that it will appear for access in Windows. I know the files are there because the tool only took a second to process...I just need for Windows to be able to see them. I am using Windows XP x64, btw. Thanks again in advance for any help.
1. In XP, run: cmd
4. select disk # (the number from the list)
eg. if the disk is number 7, type
SELECT DISK 7
Voila. GPT Protective Partion has been removed.
6. In XP, run: compmgmt.msc and select Disk Management
7. Look for the disk which says "Not Initialized", right click, then select Initialize Disk
8. Select OK to confirm
9. Right click on the Unallocated space and select "New Partition…"
10. Partition as required
