That does seem odd....The acer data partiton should be FAT32, nut that would occupy even more space on the recovery partition.
First thoughts are that you may well have to perform the recovery again, but before you do, go into the BIOS (usually F2 on acers, but might be the DEL key)
And ensure that D to D option is set to enable.
I really can't see how office and Vista could be taking up that amount of space, and it's possible that one or more partitions are holding old data, or have become corrupt.
Failing that some more info about exact make and model would help us to source an answer.
