I am trying to boot from an usb hdd "Silicon Power Armor a80 500GB" but it is not seen as bootable from BIOS.
What I have tryied:
- to plug in both USB 2.0 and USB 3.0 ports on 2 different machines (desktop on Gigabyte GA-X58-UD3R rev 2 motherboard, and an Dell N5110 laptop).
- mount as physical disk in VirtualBox
- different partition sizes and combinations: 4GB single partition, 8GB, several partitions, etc.
- windows bootloader (both NTLDR and BOOTMGR) and Grub4dos, installed in different combinations
- after each try - wiped first ~10MB of HDD (dd command from Linux OS)
- all BIOS'es, including VirtualBox are able to boot from USB - tested with an 4GB Transcend flash disk (Grub4dos on NTFS).
- waiting until drive spins-on in bios, then reset the computer (ctrl+alt+del from bios)
The HDD works perfectly from both Windows and Linux OSes, but is not bootable in any way.
Have someone encountered such situations with external USB Hard Disk Drives? Maybe some has experience with this particular model?
On manufacturer site found an firmware update utility ("MS1009033-A80FWUpdateTool_v01.zip") - but it doesn't see my HDD.
Please share your experience in troubleshooting usb hdd booting, what else I can try to make it detectable in BIOS?
Until then I assume that it is not bootable
