I'm fairly sure the answer to this question is going to be a simple no but I'd like to check anyway.
I have a 60GB hard drive split into 2 partitions, one is 10GB the other 50GB. I'd like to resize the first to around 20GB but without formatting and losing any data. I know this isn't possible using Windows disk management software but is there any third party software capable of this?
All you'll really need is enough empty space on the 50GB partition, so it can be downsized to 40GB.
I have done some resizing myself with Partition Magic. I must say that I didn't make a backup first, but all went well. If you have important data then do a backup.
Depending on how much data you have on the larger partition, the resizing might take a long time, so don't worry if it seems that the computer froze... it didn't.
(The resizing will be done after a restart, not in Windows)
