PC will not boot if USB drive is attached
Posted on 2009-04-16
I have 2 systems based on Asus M5GZ-MX motherboards.
Both systems have the latest BIOS version.
I recently acquired 2 Lacie 1 TB USB drives, both are formatted as a single NTFS partition.
These drives are used for backups and are not bootable.
I want to be able to leave one USB drive attached to each PC for automatic backups.
My problem is that neither of these PCs will boot if a Lacie 1 TB USB drive is attached.
The boot sequence does not progress past the BIOS splash screen.
If I press DEL during boot, an early message says:
1 USB device detected (I don't have any other USB devices)
The last message I see on the screen is:
Auto-detecting USB Mass Storage Devices.
It doesn't go any further than that.
These drives work fine if plugged in after the PC boots.
I have other USB drives, e.g. Maxtor that can be connected while these PCs boot.
