We have a couple of 2TB hard drives that were mistakenly put in a RAID 0 configuration producing a 4TB volume. Our imaging software has a 2TB limit on source drives so we thought we could just shrink the partition since there is only about 250GB of data stored on it.
After querying the volume for available shrink space Disk Management reports the resultant drive would still be over 2TB.
What strategies can you recommend to maximize the available shrink space?
Note: This is a data drive not an OS drive, it has no paging file. Fragmentation of the volume is only 3%. There are shadow copies on this drive.
