Fragmented drive; strange/interesting, ...

Post by ChrisGreaves »

I found this strange/interesting: Because of my recent problems, my TrueCrypt Encrypted drive ended up quite unfragmented (RoboCopy out and RoboCopy back in).

On my trip on Tuesday I took about 150 photos and uploaded them to my data drive (T:) for processing. Wednesday night I loaded Defraggler out of curiosity, and Behold And Lo! There are little blue droppings all over the pane, and each dropping appears to be a single file – an image file, a photo, from my camera.
It looks as if my FileCopy issued from within Word2003 (I know, I know, ...) caused a rhythm best described as “drop a file, skip two blocks, drop a file, skip two blocks, etc”.
I’ve done little else today (Wednesday) except type in my notes and record my weight this morning in an Excel Workbook.
The pattern I observe I would have expected to see if I had deleted about as many photo (images) as I had created.
Now that I type that, I wonder if the images were originally in a contiguous block, but that VSO Image Resizer, in resizing them in place, created the gaps between blocks. 132 files at 281 MB resizes to 132 files at 28 MB, that is, a reduction to about 10% the original size.

The analysis pane shows most of these droppings are in 2 or 3 fragments. I suspected the 18 & 24 fragments come from files edited with MSPaint, but this is not so; they are unedited images (albeit resized)

This has nothing to do with Robocopy, but is a 'feature' of the NTFS file system.
Can you explain why a defragmented and subsequently untouched file should at a later stage appear to have its clusters rewritten so that it ends up fragmented again? (I can't!)

BTW with regard to your tagline, just sticking an 'e' at the end of a word doesn't magically convert it to medieval English, nor does adding an extra 't' into waste - which has always been "waste". I advise the reading of the Wikipedia entry for "ye olde"... Also the reading of some Beowulf, Chaucer and the Anglo-Saxon Chronicle (out every Friday, price 1 groat).

I advise you not to follow my advice.​​

I guess John G told you off there, Chris!

Me neither. That's why I posted yesterday's screen.
As you may recall, I'm not a big fan of defragmenting Hard drives, but from time to time I do get curious.
FWIW last night I defragmented that data drive and will wait until I have another 100+ photos to resize (in about two weeks time) and repeat the process under controlled conditions. (1)

Well Chaucer got away with it; and his name was Geoffrey whereas mine is Chris. I've been reading an 186? book "A shorter history of the English people" (not the John Richard Green one, but someone else) and he quotes reams of text from anciente documentes, as I would say if I were prepping a tagline as a joke. :rofl:

Actually so did I.

Chris,

Looks like you've been outed by John, who's been channeling Ciardi.

Better watch out or you'll end up in circle eight!

I'm more of a "three" myself ... :cheers:
