Will you be removing the other drive from you machine? If you simply copied all from the other drive over, then after removing the old drive, changed the name & "volume" name of the new drive to the old one (say, "Media H:/ ") ... however the old one appears in your OS finder/explorer now ... then PrPro will simply see this as the old drive.
If you're adding the drive to the machine, and keeping the old one ... after moving everything, rename/re-letter the old drive, reboot, and then change the new drive to what the old one was.
So again ... if the old as say appearing as "Media H:/" where 'media' is the Volume name and H is the drive letter, change that 'up' to your next available drive letter and change the volume name. Then after re-booting, change the new drive's volume name and letter designation to match the old drive's current name.
Thanks Neil. I'm not keeping the old drive. I'll be replacing it with a new one and then changing the letter/name of the new drive to match those of the old one. I was worried that PrPro may sense the difference in both drives' ID numbers/capacities/speeds and fail to recognize the new drive as an exact copy of the old one.
Nope ... it doesn't pay that much attention to such things ... just drive letters & volume names at most.
