I recently bought a dynabook model number pp160N-000500 sx/210lnlw.which was 
workng and loaded with xp.For some strange reason I decided to format the 
hard drive and start from scratch.It has never worked since!I have tried to 
loading from both the pcmcia slot and the usb port with no success .It 
starts off ok with win setup being displayed then loading files then set up 
is starting windows.It then bombs out with the message
problem has been detected and windows as been shut down chek HD controller 
stop 0x0000007b 0xf9d04524 0xc000034 0x00000000 0x00000000.I have tried 
win98 with no success I even took the HD out and replaced it with another 
preloaded with xp setup but it still ends up with the same error code.It 
would appear that it can drag data from the HD but will not write to it 
.Have also downloaded the latest version of the bios Does the HD need a 
particular driver ?if so how can I obtain one? Any ideas?
