I've recently added an external drive to my HDR. It's a Buffalo 250GB 3.5" drive with a separate power supply connected via the rear USB port and formatted (on my pc, using Easeus partition manager) with ext3. Trouble is, when the drive is attached and switched on, the Hummy won't come out of standby - it freezes on the initial screen with the "Humax" logo. If the external drive is switched off, the Hummy wakes up normally and the drive can then be switched on successfully. I'd like to leave the drive attached and powered full time. Not being able to do so is only a minor nuisance, but I wonder if anyone else has encountered this problem and found a solution?
