And I'll add to that a little. Since the drive was formatted with NTFS, you will see MUCH less of a space savings than you would with a partition using FAT or FAT32. Additionally, compressed drives suffer more from file corruption. A single bit (the 1's & 0's that make up files) out of wack and the file could become unrecoverable. Without compression, it's much easier for CheckDisk to fix a corrupted bit. I suppose what I'm trying to say is that I don't think it's worth the extra space you would gain, especially considering the size and cost of today's super large hard drives.
