Program review and Evaluation - 'Defraggler' from Piriform

First looks and some Theory:
When I downloaded this program, it was a recommendation from a friend. They suggested I ran it to improve performance on my PC. In basic, their are lines on a Hard Drive with a set amount of space on them. Whenever you write a file bigger than a track, it often writes that file onto the next track. Eventually, the Hard drive becomes a mess... Defraggler aims to correct this by moving these chunks closer together making it quicker to read/write them.

The program has a sleek, easy-to-use design with clear buttons at the bottom-left showing you the main functions of the program. It also has a simple drive capacity chart on the right and drive selection menu at the top however the 'drive map' can be somewhat confusing. However the designers also introduced an option whereby you can set a defragmenting schedule for either your main drive or an external drive (flash, SSD or hard drive) and it is very satisfying to see all of the drive map blue indicating minimal fragmentation!

A downside of this program is that it has no compatibility with Linux 'wine'. It has been explained to me that the Linux default file-system (ext3 or ext4) is very efficient at not fragmenting the drive whereas 'NTFS' (which is Windows' file-system is much less caring. Either way, I was still interested in seeing the 'bad sectors' of my Linux hard disk and if there was anyway of optimizing the performance of an already slow and ageing disk.

Evaluation - What I would do to make it better:
1) I would make the drive capacity chart more colourful (i.e. show red as fragmented and blue as not and so on)
2) Allow for compatibility in Linux environments
3) Even though it runs as an administrator on the computer it occasionally can't defrag some large essential system files. This irritates me lots

Thas' all folks!
