I often find after a defrag it is video files that cant be defragged I think it is the nature of the beast.

hi Marg7, ok its a 107 Gb drive with 14% free (15.74 Gb), it seems to de-frag real quick leaving shed loads of fragmented files
(log included in post )
how does chkdisk work, could you advise pls

eedcam , ive DL'd 100'sGb of video over a period of years, and have never experianced a drive that wont de-frag, is it possible you have the same issues as me ??

Volume siz = 107 GB
Cluster size = 4 KB
Used space = 90.98 GB
Free space = 16.07 GB
Percent free space = 15 %

Free space fragmentation = 0 %

File fragmentation
Total files = 148,553
Average file size = 1 MB
Total fragmented files = 82
Total excess fragments = 438,493
Average fragments per file = 3.95

all help much appriciated folks , thanks

Hi Mole 15G/b is no space really with video particularly editing Also there is a bottom limit for defragging I think 15 is pretty close as defrag needs 12% space I just got that warning with 15.8 space on drive. I'll do one today and post the failure to compare

hi eedcam, im not able to make sense of the comparison really, ive freed c off to 21% (22.7Gb)and still finding massive fragmentation - although each time i de-frag im noticing small changes while files are being compacted, as if its chewing through it a bit at a time ( eureka ) its been a while since it had a good one so maybee this is our solution - keep running it ?

Me neither |Mole though my videos are in various formats would think it is Space available in your case .For the record I have also a 350G/b drive with 325G/b space and still was analysed as needing defrag

The free space shown available in Windows Defragger is a total overall figure of free space on the drive, I use Perfect Disk to defrag and it shows the largest single available piece of free space as well as the combined total figure of free space, I mention this for two reasons, the first being that a 2Gb file will need at least 2Gb of free space to be defragged into and secondly both eedcam and Mole-Inc seem to have a lot of fragmentation, including page file fragmention which spread over the drive could perhaps prevent large free space blocks being available to defrag a large file into.

Have a look here about pagefile fragmentation

I have reduced the Windows default cache sizes for temp internet files, recycle bin and system restore to try and maximise free space.

The defrag prog I mentioned Perfect Disk will allow a single file to be defragged, in fact they mention as an example a video or audio file that might be skipping. I have just analysed one of my drives, it has 57 Gb free out of 80Gb and the largest single free space is 18Gb.

I capture video from my camcorder a lot and find it pays to defrag after each capture and after editing and it seems to work OK.
Maybe you could copy the videos to disc, then delete from the hard drive then do a defrag, then put one video back at a time and defrag if needed after each one is added, Les.
