Vista keeps warning me that D partition has very little space available (5.3GB all used up). C partition has 292GB. So, using the Vista partition manager I reduced C by 20GB. PC showed 20GB unallocated. But, when I tried to extend D the extend option is greyed out. What to do since I believe the restores are on D and it appears to be too small. Thanks in advance for any assistance. Jay600

Your D partition would be the recovery partition set up by HP and has no need to be larger. Disregard Vista warning.

Start --> Settings ---> Control Panel ---> System ---> Advanced System Settings Under the Advanced tab, go to PERFORMANCE Settings. Then go to the Advanced tab again. Under Virtual Memory, click CHANGE. Select Drive D: and then select NO PAGING FILE, and then click SET. Reboot. (This will delete the paging file from Drive D: freeing up some space, getting rid of that Vista warning.) Just make sure you are doing this for Drive D and not Drive C - drive C needs a paging file to operate properly.
