The REAL disk hog
Ok,
I am sometimes a slow study, but I finally got a handle on why my 60gig HD was always so frick'n full. And why I kept having to delete 10MB applications to keep 200MB free on the disk. It was the ThinkPad auto Backup utility. It is set by default at the factory to make a COMPLETE copy of the C:\ drive ON the C:\drive. Basically forcing you into a software RAID configuration. Now I have a back-up utility that grabs my hard drive every night and copies it over my home LAN to my own RAID system. Also Windows is running it's own restart and recovery backup. So here is how the math was working. Base Windows, about 10gig. Windows was creating it's own back-up and using the .Cab files, double the 10 gig = 20gig. Then about 6 gig of other new applications and music, etc. = 26 gig. ThinkAdvantage was copying that whole partition on itself = 26x2= 52 gig. With windows overhead and a system partition, the 60 gig drive only had 52 gig of free space. Therefore my drive was CONSTANTLY full. And full with multiple copies of itself. Then my home back-up software was copying the whole 52mb (with three copies of windows already in there) over to my RAID system. Wow, no wonder the disks fill up so fast.
So what did I do? I deleted the back up to local hard-disk in the ThinkAdvantage back-up configuration. Presto, 26 gig more space. I was thinking to disable their back-up all together since I have one at home, but instead added a back-up to a network drive in the office giving me TWO back-up utilities running on this drive. Never enough. Just started de-frag. Wow, what will I do with all the space!
