How do I schedule Vista defrag to defrag ONLY drive C:? Whenever I start defrag it goes through all the partitions and the external disk and the XP disk and it takes forever. Once I thought I was wrong, now I'm not so sure!

You cannot. For Vista desktop defrag it's all drives & partitions or nothing. The workaround is to either do it from the command prompt (CLICK ME), or opt for one of the free third party defragmenters (LOOK HERE). i_Xp/VistaUser

Thank you XPUser... I have bookmarked the "CLICK ME) page... there are a lot of useful utilities there. I have Diskeeper" but for the life of me I cannot get it to work on Vista. Other users have no difficulty with it but I'm blowed if it will work for me. I like the look of AusLogics meantime. Thanks again. Once I thought I was wrong, now I'm not so sure!

If you install SP1 RC1, then you will be able to schedule whichever drive/drives you wish to defragment separately. Other than this, there are standalone defragmenters as advised above by the reputable forum member. Regards suatcini

Thank you suatcini... I guess I'll wait for the official release of SP1 next year, in the meantime it's AusLogics (not to bad really). Once I thought I was wrong, now I'm not so sure!

Auslogics does its job very very quickly. Vista's own defragmentation engine takes very very long to defragment. For these reasons, I stopped using Auslogics because I do not think it does a job of defragmenting in such a short time. And I rarely use Vista's own defragmenter because I do not often install-uninstall software to cause fragmentation. I also installed SP1 RC1 and it runs well. Regards suatcini
