I recently upgraded my hdd with xboxhdm (i've done it before), and everything worked fine. I switched back to my old hdd to ftp some more files to my computer to put on the new one, and when i put the new drive back in it got stuck at the bios and the white microsoft word wouldn't show up. (I actually left it at that screen while typing this and after a few minutes it suddenly booted to avalaunch) It sounded like it was constantly trying to read from the dvd drive or something. I guess its working now, but would anyone know what would cause that to happen?

Never happened to me before...

Update: it does this when switching between dashboards as well...

however, i may have fixed the problem, i switched back to the old hard drive and tried booting to the m$ dash and it gave me an error 12 (unk. dvd error) so after testing for loose cables and whatnot, i ended up swapping the cable for a new one and its been booting and switching dashboards fine since then (about 10 min ago )

I'm still curious if anyone else has had this problem before, and any fixes for it, so don't be afraid to reply

Hopefully that might help someone else who has the same problem.

HEY, Im having the same problem

I posted mine in General Hardware Faq -

same thing when going to emulators or other dashs.
But no help on it yet
So Im not the only one

if it stucks at the begining , check the jumper , it must be master set

Mine is set to master. Its been on master when I did the upgrade.

Actually I think its supposed to set to Cable Select... try that
