No, it really shouldn't be timing out -- the wait time is already HUGE compared with how fast the drives process even the largest of commands.

That said, I'm still poking around here with my 160GB drive, and all is NOT well.. I suspect there may be a bug or two in Hijack's LBA48 support (it never has been rigorously tested before).

So I'll dig into that a bit and perhaps have an update again for you to try tomorrow.

Cheers
