One of my computers has an 80GB boot drive (single Primary partition formatted NTFS) and two indentical 200GB data drive (both primary partitions formatted NTFS). All three drives are on separate IDE controller channels (boot drive on enbedded Intel controller, data drives on a Promise two-channel controller via PCI card). These are all plugged into an Abit AA8 motherboard running Microsoft Windows XP Professional, with Service Pack 2, and all critical updates.
The two data drives are used for authoring and ripping DVD ISO images. Recently, I noticed one the second 200GB data drive I could not rip an ISO image file when I had already consumed 100GB on that disk. This wasnot the case for the first data drive. Also, I noticed that the ISO image rips were being written to disk in fragmented form.
Additionally, inspection of the two data drives in Disk Defragmenter shows that both disks are reserving a space on each of the disk near the beginning, and the amount is about 20-25Gb in size. System restore, indexing, etc. have been disabled, and multiple re-partitionings, reformattings, etc. to the two data drives yield the exact same behavior.
I know this should be an issue with 48-bot LBA from the operating perspective, because this is typically enabled during SP1 or SP2 installation. Also, I can copy enough data from one data drive to the next to sufficiently consume disk space to a point the reserved area is no longer reserved. Still, why is it reserved?
During the ripping and or authoring of DVD ISO image files I have tried a variety of applications (include that which came with the Pioneer A07 writer drive) and all produce the same end results. Surprisingly, though, when I copy these 5-9GB ISO files from one data drive to the other data drive they are not fragmented at all.
Can fragmentation lead to an inability to rip/author to an unreserved space +5-times the size of the intended ISO image file? Anyone got an idea what is reserving this space on the disks near the beginning of the disks? Is it common for a ripped and or authored DVD to be written in fragmented form on a disk, even a disk which was just reformatted with nothing on it?
