OK I grabbed a new USB drive (maxtor Basics 1 TB), Ive copied a whole load of stuff over and every on the disk is fine.....

Until I reboot, then when I select the Drive it says "disk needs to be formated", after a moments panic I Unplug the Drive and replug it, Perfect no problems at all.

Reboot again, Same issue.

To get the drive working I need to power or plug the drive after booting up otherwise it says it needs formating.

My other USB drive is working fine (500gb Seagate) so I dont think its a USB issue, only thing even abit strange is that this new drive is flagged as Active in Disk management (TBH I dont even know what that means).

Vista 64bit BTW incase that helps.

If anyone can save me from transfering 700gb of data again then I will be over the moon. Thxs allot.
 
Might be something to do with the BIOS trying to boot from a USB drive, I'd disable that (by having the USB drive lower down the list than the real boot drive) and only enable when you actually need it.

Not sure why the drive (partition) is marked Active, only the boot drive with NTLDR and boot.ini (system drive) is normally marked active. Maybe you can 'un-mark' it in disk manager...

Edit: OK, you can't - but you can do it this way (found on the net)

Open up a command prompt and type DISKPART.

Type LIST DISK
Type SELECT DISK n (where n is the number of the old Win98 drive)
Type LIST PARTITION
Type SELECT PARTITION n (where n is the number of the active partition you wish to make inactive)
Type INACTIVE
Type EXIT to exit DISKPART
Type EXIT again to exit the command prompt
Reboot

I have a very similar problem with my 1Tb Lacie drive. If it's on my computer wont boot. Scans the IDE/SATA then gets to 2 USB Drives Detected and just freezes. Have to turn on the 1TB extrernal drive and power cycle it to get it to boot.

Definitely not trying to boot from it. Happens before all POST stuff is completed so I don't think it's related to the OS in any way.
 
Well my USB mouse is still working with legacy mode disabled so Im not sure what its for. If enable it I have to wait 5 mins for my PC to boot up.
 
Thinking about it, all the USB1.0 stuff I have is mostly junk. So probably not missing much. Might do it meself then and see if it speeds up booting :)
