what does it mean when i get a blue screen of death with the phrase "volume is dirty". i got it 4 times in a row. windows xp home starts and just before the desktop comes up i get the blue screen. i have 2 hard drives. c is the primary and f is the slave. it tells me f is dirty. i am defragmenting it right now. i never had this problem before. i do have win xp pro installed on it, but it never interfeared before. i just use it put stuff on there. nothing recently. i did a early hard drive failair test, but it came up with nothing. any ideas?
