I have recovered different Toshiba notebooks and know how it works but after reading your posting here I’m pretty confused and I don’t understand your problem.
Before recovery installation starts the whole HDD will be formatted and old partitions removed, new partitions will be created (C and D) and OS will be installed on partition C. This is what happen when you use recovery DVD.
After recovering you can open Windows explorer and you will see both partitions there. So what is your problem now?
One more thing that can be important: have you installed recovery image using recovery DVD or using HDD recovery installation?
Used the recovery DVD to reinstall Windows, but noticed during installation that it was removing the partition identification letter. The result is that, where previously the DVD drive was D:/ and the partitioned drive E:/, now D:/ has disappeared and the DVD drive is now E:/.
Now, according to Windows Explorer, the C;/ drive is 116Gb, suggesting that the partitioned drive is still there but not being recognised as,when purchased, the A200 had a storage capacity of 420Gb.
I've tried looking at Windows setup but it's not giving me any options regarding drive recognition.
I hope this helps but wonder if, as the original problem was caused by a Windows update, this could have any bearing.
How the partitions will be created before recovery installation starts is defined in recovery image so you can install OS using recovery disc 1000 times and the result will be always the same.
After using recovery installation you can change partitions but after recovery image installation you will have the same situation as before.
If I’m remembering well after recovery installation you will see two partitions on HDD (C and D). Optical disc drive should be E. On the second partition D there will be copied recovery image and saved in folder “HDDRecovery”.
Yes you can partition as you want after recovery but if you use the windows parition manager it has limitations. for example I cant shrink my C drive beyond 200GB due to files at the end of the drive. So you can use the free tool like mini partition wizard CD. very easy tool to use.
