Need Help, made clone uses different registry original.

[Susek0013]

Okay, I made a clone of my data drive (Z: ) going from a 1tb blue Western Digital to a 6Tb black WD HDD. I used Acronis true image software to perform the clone. When I started up after removing the Z: drive and went to open a program though a shortcut, it couldn't open. Telling me that the disc or network connection was unavailable. So I checked my 6Tb HDD and it reads as (E: )Drive. Is there a way to change it back to reading as my Z: drive?

Update: I managed to change my Drive letter to Z: from E:. But it only allocated 2Tb of 6 to Z:. Can I somehow add to the rest so i can use the full drive?

Right click on the Start menu and do a search on Computer Management.
Under Storage, click on Disk Management.
Check the display of the 2TB drive, there is a good chance that only 2TB is in use or specified as the partition size and the remaining 4TB is Unallocated.

Can you verify this?

Are you indicating that when you FIRST checked the secondary 6 TB HDD IMMEDIATELY FOLLOWING the disk-cloning operation the disk contained a E: partition of 6 TB with no unallocated disk-space? And it was ONLY after you changed its drive letter to Z: that the drive's partition was 2 TB and the remaining disk-space (4 TB) was unallocated?

Can we assume your 1 TB source drive is MBR-partitioned?

Yes, it shows as unallocated. When I tried to extend the volume I got a message saying "Only the first 2TB are usable on large MBR disks. Cannot create partitions beyond the 2TB mark, nor convert the disk to dynamic."

That's your problem. Remember - a clone is a clone is a clone. Your 1 TB HDD source disk was apparently MBR-partitioned, so when you clone that drive it carries over the partitioning scheme to the destination drive, i.e., your 6 TB HDD. It doesn't matter if the 6 TB disk was GPT-partitioned; the clone's partitioning scheme overrides it.

Fortunately the 6 TB disk is a secondary drive so you should be able to use a third-party partition management program to convert the disk from MBR to GPT without data loss. I believe most of those programs' free versions have this capability; all their commercial versions certainly do.

BUT REMEMBER - AFTER THE CONVERSION PROCESS, DON'T DELETE ANY DATA FROM YOUR 1 TB HDD UNLESS YOU VERIFY ALL THE DATA IS FULLY CONTAINED ON THE 6 TB HDD.
