Hi magruseR,

I had never put my thoughts on dynamic disks and so I usually stay away when I see dynamic disk .(gregrocker knows. I had roped him in another thread where I saw a dynamic disk with two separate partitions with the same drive letter with an intermediate partition.)

But my indulgence in GPT disks gave me atleast some insight into it.

In GPT disks Microsoft creates a 128 MB MSR partition specifically intended to store any reversible data that any software may keep for the reversal process.. For example when you convert a basic GPT disk into a dynamic disk, the data necessary to convert it back to a basic disk will be stored in the 128MB Microsoft System Reserved Partition.This 128MB MSR partition will not be visible to the user in Windows Disk Management and therefore cannot be meddled with by the user and all such data is safely held.

In the case of MBR disk this reverse process data is kept in hidden sectors 1 to 2047.

What I believe has happened in your case is that when you did the clear/delete and whatever else you did to get rid of the first partition, has also cleared the sectors 1 to 2047( Doing a diskpart clean also will clear off these sectors) and therefore you have lost the ability to reverse it from dynamic to basic with that reversal data lost.

Your only option in such a case will be, to backup all data to another drive, delete both the partitions and create a new basic disk. If you cannot do that in Windows Disk Management you can do it with any third party partition/format software.

Also do a drive cleanup as in my post Ext USB drive has drive letter but does not appear in Explorer to get rid of old drive data in Windows Registry. ( Do this after disconnecting your 1TB drive. You can reconnect after a reboot on completion of the drive cleanup.)

Hiya Jumanji,
You are correct some of the sectors between 1 and 2047 were indeed deleted during my attempt to resize F ... I have now borrowed an ext hdd off a friend to do as you instructed (with easeUS)
Thankyou for your time
