I was putting together my mothers new PC (mainly my old components) and decided that her hardrives were a mess and that I was going to merge the partitions. On one the drives, I deleted and formatted partition B, and tried to merge it with partition A, simply by extending partition A to encompass the remaining capacity on the physical drive. Much to my horror however, the end result was that the whole of the physical drive was rendered into 500GB of 'Unallocated Space'. There was lots of very important files on that hard-drive and losing them would be totally out of the question. Does anyone know how to go about recovering a deleted partition?
