usb hdd power cycles twice during boot

[her34]

i got a usb hdd and when i boot the hdd power cycles twice before entering windows desktop. the system hangs while waiting for the power cycles to complete. the drive functions fine in windows and is connected directly to computer, no hub.

my previous usb hdd had a ide drive inside which never had this problem. my new usb hdd has a sata drive inside.

is this normal behavior? can it be stopped so that the drive stays on continuously

I believe the solution is to enter the BIOS and disable the ability to boot from a USB device.

Do not confuse this with disabling legacy USB...that's something you need to leave enabled if you use a USB keyboard.

I think it's because the BIOS resets/initializes the USB controllers, and then Windows does the same thing when it boots, and your enclosure cuts power to the drive when the USB port is powered-down, however briefly.

IOW, it's your enclosure.
