Just the system drive here - interested to know what y'all regard as your best average with regular maintenance? I still maintain - even with my XP Pro - Windows as ever makes a mess!

Since COMMISSIONING my HP4600 a good SEVERAL weeks ago now - I have assiduously defragged (O&O Defrag) ...... and starting at about 5% get back to 0.5% - always just four frag files that won't get corrected!

I don't remember managing to keep it this low on last machine but - interested to know what folks regard as best they can achieve with regular defragging.

A vote will do - oh - hang on - where's the poll option? Hmmm - no can find!.

OK - base line let's say 5% or LESS ...... then 10%, 20% etc. Pure curiosity!Steady 5% or less here as i do it weekly...
I use Auslogics.
Different apps will report different #'s as far as efficiency...plus you have to account for the pagefile and restore points...I only defrag occasionally and don't keep track of fragmentation - I also defrag the pagefile PERIODICALLY. A good utility is here: http://technet.microsoft.com/en-us/sysinternals/bb897426.aspx.

that's kind of odd- I've only defragmented once since I got this computer about 3 or 4 monthes ago, and It's on almost all the time... system drive fragmentation is only 1%...
