So this it what I did; When I bought my brand new Macbook Pro 13" at the local dealer, I also bought a separate SSD and replaced my HDD with it. The HDD caddy to replace the HDD with took some time to arrive from Ebay, I couldn't help myself but completely setting up my Macbook with the SSD and thinking I'd simply relink my data files afterwards. Coming from a Windows machine I thought this would simply mean changing some paths in some settings (damn me for not looking that up first!)... So I went ahead and set the whole thing up (including Parallels with Windows 7 and 32GB HDD space for it) When the caddy arrived, I installed the reformatted 750GB HDD in the superdrives bay. As for the software changes, I ended up copying my whole user folder to the HDD, relinking it in user settings and deleting the one on the SSD thinking that was that , not realizing that the Windows 7 file was also in it. The file itself was only 11GB but Parallels did snatch up more than that (I seem to remember, not 100% sure though) When booting Windows 7, I noticed an unbearable lag so I went to look for the Windows 7 file only to find it on the slow HDD. So I moved it back to the SSD. After all this, my free disk space on the SSD is 36GB of 127,1GB. This is weird because before installing the HDD, I had about 80GB free space. the desktop icon of the SSD shows 140GB free space When I press the space bar though, it shows it only had 36GB free space. When doing cmd+i it also shows 140GB free space The disk manager (or whatever it's called in English, in Dutch it says "schijfhulpprogramma") also shows only 36GB free disk space Seems to me that I've lost at least 32GB in SSD disk space because I moved the Windows 7 file, and moved it back again. I remember, before moving the file back to the SSD, missing about 32GB's on the SSD although showing 90GB of free space on the desktop icon, moving it back only made it worse... Does anyone how to get back the disk space I lost by moving the windows 7.pvm file?
