finally its solved - no it wanst a drive issue nor did i need that patch, it was as i though, because vista caches mem and farts about with mem in a different way to what xp does, and seeing as the tool is no longer developed, it doesnt understand and so the read rate goes up and down like a whores panties.
If you put the buffer amount in dvd decrypter to 1mb, the read rate is rather constant and stable - if you have it as 20mb (default) its a bit strange and if you give it the full 256mb, then your in for some fun
, one of the strangest things is that the more fragmented the drive is the less issues i get, if the drive is in perfect condition i am also wondering if its too fast for dvd decrypter to keep up, seeing as its sata to sata, maybe its not quick enough to update the info on screen
Have done this under XP SP2 and vista and they both do the same - near enough
Only one more prob to go (not a real prob more a cosmetic thing) and i might get vista in new year
Should drives be foremated under the OS they are running or doesnt it really matter ? i have noticed that vista tends to squash the mft and mft zone of drives that are formated with 2K or XP
