Windows 7: System Keeps rebooting when External Hard is attached to it


18 Aug 2012   #11

Windows 7 Ultimate 64bit SP1
 
 

I had the same problem with a WD 1TB external, but mine would never boot when it was on/attached, I think (from reading on this forum) it has something to do about legacy usb?, sorry to be confusing maybe someone knows what I'm on about.

Also are you able to connect the drives once you are booted.

Can you then go to Control Panel>Administrative Tools>Computer Management>Disk Management
Then take a screen shot, or look to see which drives show as Boot, or Active.
The first one after two restarts, yes it boots OK.
The the second one is new and I haven't tried it on Windows 7.
Yes I am able to connect to them after the computer boots up.

Could you explain what exactly is "Legacy USB"?

Thank you.

Quick Review
This BIOS feature determines if the BIOS should provide legacy support for USB devices like the keyboard, mouse and floppy drive. This is a useful feature when using such USB devices with operating systems that do not natively support USB (e.g. Microsoft DOS or Windows NT).
When enabled, the BIOS will enable legacy support for USB keyboards, mice and floppy drives. You will be able to use these USB devices even with operating systems that do not support USB.
When disabled, the BIOS will not enable legacy support for USB keyboards, mice and floppy drives. You will not be able to use these USB devices with operating systems that do not support USB.


Sorry to be vague it was in the BIOS, there was an option about enabling/disabling legacy at startup, I'm not sure maybe someone could shed more light on it, but from what I remember of it some people disabled the option so there system started up with external drives attached and on.

Do you have anything bootable connected to the bootable add-on card(s)? If not try disabling booting from those cards, so that it doesn't even appear in the boot order.

Have you always had your Main drive C: partioned into 3 different partitions?

I am maybe just guessing here if that is the issue or not. You have lots of external space so just curious why you would want to partition your Main Drive.

Thank you all guys
I have disabled the Legacy USB (it was enable) and now both of them are working properly with no problem and computer boots up properly too.

Thank you,
