Hard Drive fragmentation

I also checked my hard drives for fragmentation. The 'C' drive which holds the OS and most of the computer programs was not fragmented. The 'J' drive which holds all my web programs and HTML files was not fragmented. How ever the 'L' drive which I just set up as my external back-up hard drive was 100 % fragmented.

Having the external drive completely fragmented doesn't sound good, I've only been running the drive for a week now. Judging by the file name it's currently de-fraging tells me that the back-up software generates the back-up as some compressed file format and not a group of changed files ~ under their original files names...
