I got a hold of a Maxtor 6300f0 DiamondMax 10 300gb Sata3.0Gb drive to use as a files store on my main pc: P4 3.0 Abit IC7-Max3 2GB PC3200 All was going fine, the computer booted up, found the new drive etc. I went into administrative tools>computer management>disk management and set up the drive, formatted it and proceeded to move about 10 gb of files over from my existing drives. All was going fine... Then I did a reboot and the computer went into a cycle of shutting down then restarting. It did it about 5 times before i did an F8 and went into safemode. Now the only way to get the computer to start is to unplug the drive. It then boots up into windows fine. Otherwise i have to leave it connected and go into safe mode. Any ideas?
