Hyper-V VM Issue

HI Experts,

I have an issue with a VM in Hyper-V

I created a disk too small for an SBS2011 which I partitioned into two. (C and D drives)120GB in total.

My problem is I created a snapshot some weeks back went to do a increase disk size (had never done this before) didnt read the instructions closely, created an increased size disk and could'nt boot.

Got out of trouble with that part of it through vhdtool but my problem now is that I can't seem to merge the avhd to the parent disk  -

followed these instructions it seem to work fine until I rebooted and came up with an OS error.

Used the correct dated avhd but it is smaller which didnt make sense...

BUt I seem to have two avhd's which is confusing me as I only created one snapshot

the size of the parent vhd is 114GB

the size of the 1st avhd is 34GB (this one had the current date and time)
the size of the 1st avhd is 48GB (this one was a few weeks ago)

really confused as the size of the whole disk is 120GB... how on earth does that work out to be? that would really love it for someone to shed some light on this thankyou.

thanks hanccocka,

I had a chance to review the document but that doesnt get me sorted though, really stuck on this one...

This morning  I reliased what had happened last night is that after I renamed the latest .avhd it merged with the other .avhd (which I really dont know why it is there) going to play around with a backup I made of that folder on another server.

I tried merging it with the parent .vhd that worked but would not boot....  I shall plod along
