As a new 622 renter, I've been unplugging the 622 (actually as a former 921 owner I have a power strip just for the 622 so I don't have to move the cabinet) allot to move it around, add a laptop cooler, etc. The last time I did this the unit locked up during second stage of reboot where it is checking all the transponders. I had to power cord reboot two more times with a manual check switch test to get the unit running again. Although the problems with the 921 were legion, It always was able to power cord reboot without problems. Is this a new bug? or a known bug previously posted. I wonder if the hard drive in the 622 is really that sensitive to gentle movement while running? ( after all, Ipod and laptop disk drives are being moved constantly while in use.) It seems that the 622 does not like to be power cord rebooted.
