In versions of Drive Bender prior to v1.3, when a pool is removed the reference to that pool is not deleted from the drive. If this drive is then added to a new pool (and the drive was not formatted), the drive will contain two pool references. If this is the case, restoring a pool from drives can be problematic, as Drive Bender will not know which pool is the correct one.
To fix this issue, these invalid pool references need to be removed from the drives.
The following image show a pool reference file (*.PI file), there should only be a single pool reference file per drive, and it should be the same for all drives within that specific pool.
First mount the drive via Windows Disk Manager. Open Windows Disk Manager (right-click Computer, select Manage, from here select Disk Management), find the drive in the list of drives available on the system. Right-click the drive and select "Change Drive Letter and Paths", and add a drive letter to the drive. Now the drive can be viewed via Windows Explorer.
If there are multiple PI files, you need to determine which is valid, you should examine each drive in the pool, the PI file that is the same for all drives will most likely be the one to keep (if all the drives contain the same multiple PI files, simply pick one to keep). All the other PI files must be deleted from the drive(s) so you are left with a single common PI file on all drives. Do not delete any other files or folders.
Once all drives have been cleaned up, you will be able to run the restore from drives without issue.
