Dear Expert

I have got two HDDs each one is 40 GB , and each one has only one partition type NTFS.

One of them for OS windows7 and it is called C (Primary Active) and other for data and it is called D as depicted in the snap shot below :

I run out of space for the hdd that has OS windows 7 ( C ) .

I bought a new hdd 500 GB and divided it to two partitions each one is 250 GB in size ,,,,one of them is G and other is Z

What I did I used Aconis and I copied the whole hdd C (the one has run out of the space) to the partition G (Active and Primary) on the new hdd (500 GB).

I unplugged hdd C (40 GB) and left hdd D (40 GB) Now I was able to boot the computer using new hdd (500 GB ),,,,,,When I tried to use windows Manager section to change the drive letter for new hdd (G to C) by following the procedure below :

Advise start over. Zero fill your new 500GB. Clone your 40GB to your 500GB. Then in Windows manager you can activate the rest of your HDD that is left over and make your partition on it from there. Once you have done this one you can use I think this progam. I never have used it before but I think it can be used to increase and resize your two partitions on this one. Then you can use this drive as your boot drive and when it is installed as your primary HDD should automatically recognize as C on its own and second partition should recognize as D. If you want to rename the D later on you can do this one. Then after this you can add back on the other 40GB HDD you have there and it should show up as E F or G depending on what else you have on your system such as lectures attached to the MB.

Assuming the drive letter reassignments are stored in the Windows registry, I would change the drive letter of some other drive and monitor the changes to the registry. That should identify the affected registry key. Then use regedit.exe to examine this key in more detail. Perhaps the solution will be obvious.

If you can't find a registry monitor application, then use regedit to export the registry to a text file, say before.reg. Then change the drive letter, and re-export the modified registry to after.reg.

Now compare the two copies using fc.exe in a cmd window:

fc before.reg after.reg > diffs.txt

I don't know if the latter technique is possible in Win 7.
