Three, it places the files the software *thinks* you need most on the fastest portion of the drive/partition - this is often where program X differs from program Y, e.g. Two, it packs the stored data towards the beginning of the drive partition - Note that Windows intentionally places some immovable files away from the beginning of the Windows or system partition, so you won't get perfect results if/when you only have a relatively small amount of data, e.g. One, it tries to place the small chunks of data that make up each file next to each other in sequence - that way the heads aren't jumping in & out to read each file. Finally, data is stored in small pieces or chunks.ĭefragmenting a drive does 3 things. ![]() ![]() The circumference of the drive platters is of course larger at the outer edge - tracks close to that outer edge contain more data than those nearer the center. laptop & less expensive drives typically spin at 5400, while performance drives spin at 7200, & high performance drives might spin at 10,000 or more. The faster those platters spin BTW, the better the performance, e.g. Save | CancelĪ conventional hard drive stores data on round discs or platters that spin while the read/write heads move in & out, away from & towards the center. It is one of the reasons Microsoft defragger by default does not attempt to defrag large files with fragments bigger that I think 64Mbytes as the read time is more significant as a seek and moving large chunks of data just grows the VSS protection databases eating freespace with practically zero benefit. It is not a fault or operation of the defrag program. Defragmenting usually involves alot of writes to the target drive so in doing so the databases hidden away in the System Volume Information will grow proprtionally. If so that works by keeping databases of the drives sectors previous contents everytime you write to the drive so it can produce a historical record of the drive that it can restore the previous state using system restore and individual files if previous versions is supported and earlier versions of the file exist that could be restored. Sonia M, would I be right in deducing that you have system restore protection enabled on the drive that lost free space during a defrag session?
