Why does Vista restrict the size of a new partition?

by abe-tolentino / February 16, 2008 12:55 AM PST

I am having problems with shrinking the volume of my C drive in Vista Home Premium. My new HP 6700 series laptop came with a 250GB (actually 232GB) hard drive, pre-partitioned into a 220GB C drive and a 12GB D drive containing the laptop's recovery files.

I would like to break the 220GB C into three drives: 60GB for Vista, 50GB for XP (for dual booting), and 110GB for data. The only problem is that when I use the Vista disk management application, I can only shrink the C drive by a maximum of ~67GB. I have tried and that shrink works fine, but my C drive remains too large (~155GB) and I can't create the third partition I want.

I have seen previous posts talk about Gparted, but I am not fully comfortable with Linux (especially since there seems to be special requirements for NTFS drives). I have a copy of Partition Magic 8 that I used on my old XP laptop, but I have discovered that many of my older programs have compatibility issues with Vista (Acrobat 6, for example). And I am pretty sure that installing PM8 on two systems is a violation of my EULA (though I do plan to wipe the old system).

Should I simply use PM8 (assuming it is compatible with Vista) or is there something I missed with disk management in Vista?

Thanks for the help!

Disk partitioning, resizing in particular is not a strong point of Vista.

GPartEd for dummies

Ok, it took lots of sweat, some tears, and possibly some blood also (from ripped out hair), but I believe that I finally have my new laptop's hard drive partitioned the way I wanted. (It's still chugging along, but everything looks promising so far.)

I tried my copy of Partition Magic 8 and it doesn't work on Vista. Even if I ignored the compatibility issue warnings, there was no way to get PM8 to work on Vista. I searched the interwebs for another solution that would be free, and GPartEd kept coming up, but it required a Linux live CD but I kept running into problems with NTFS formatting, which required a few extra files that I couldn't figure out how to include.

I must have been using different search terms this morning, because I finally found a GPartEd live CD that supports NTFS and it's a breeze to work with. You can read about it here ( and snag the ISO here ( If you don't know how to burn an ISO image to a CD, get the free version of DeepBruner and it's a cakewalk.
