Booting from USB Devices = crapshoot

So now I've gotten to learn that some USB devices just aren't bootable in some systems. My 1TB Samsung HDD in the Oyen Digital 2.5" USB 2.0 / eSATA enclosure apparently isn't treated as a USB HDD in my Gigabyte LGA775 motherboard in my main desktop. It's not listed in the Hard Drives, and picking USB-HDD = a system lockup after "Verifying DMI Pool Data...". It is listed as a mass storage device ahead of the device listing. It will boot fine if I connect it via eSATA (as expected). The same 2.5" external enclosure works perfectly on 2 of my 3 laptops. The oldest one, a Dell Inspiron 8600 doesn't see it in the boot menu the first time, but shows up after a reset (CTRL+ALT+DELETE) and can be booted from successfully.

I have a 16GB OCZ Rally2 (the $5 BF ones from Newegg) and it won't boot in my Acer 1810T. It shows up there as a USB-FDD, I can pick it to boot I see the syslinux line and then it just sits there. But, it works fine on my two Dell laptops (Inspiron 8600 & E1505). I haven't tried it in my main desktop yet.

I guess the moral of the story is if you plan to boot from a USB device you'd better have more than one with the same tools on 'em and have a CD or DVD as a backup plan. :salut:

No problems with flash drives, but I've had some with enclosures.

Well the 16GB OCZ Rally2 won't boot my desktop either. It and the 2.5" Oyen Digital enclosure will boot my Atom ITX system though.

Like I said... crapshoot... :sunny:
