How do I shrink an SSD partition? When I try to shrink the volume, the "available amount of space to shrink" is zero. I did a disk defragmentation (I know it's bad), but it still comes up with zero. Any tips or pointers?

I am using Windows 7, Vertex 2 240 GB, MacBook Pro, NTFS, and I have about 70 GB used. I also turned off hibernation and turned off paging to reduce large files.

What is your OS (Windows or Linux, ...)? –  Khaled Apr 19 '12 at 15:28
    
You shrink it the same way you shrink a volume on an HDD. –  Zoredache Apr 19 '12 at 18:41
    
This is unrelated to the device being an ssd, and probably is due to some feature of the filesystem on the partition or the software you attempted to do the shrinking with. Please divulge OS, filesystem type, amount of free space and what software you tried. –  Eroen Apr 19 '12 at 19:33

A great tool for managing partitions is GParted, works great. It works on both Windows and Linux.

Often this is caused by an unmovable file at the end of the partition.

"Shrink volume" actually calls into the disk defragmenter API to move blocks around. If it is unable to move a block, then it'll still be unable to move the block if you manually launch the Windows disk defragmenter.
