It starts with a slight audio drop-out... then a intermitent pause... then a freeze for 20-30 seconds....finally...everything is locked up....nothing works...the only thing left to do is hold the power button or pull the plug. Need to do this...three, maybe 4 times a week. Is my hard drive failing? Is there a bad spot on the drive or the inner or outer sectors unreachable? Anyway to run a hard drive test and mark bad spots? Anyway to defrag? I don't think it's heat related. Fails on new recordings... Fails on 8-month old recordings.. Fails when I pause and rewind live TV. Sometimes I can record 3 HD (2 SAT and 1 OTA), while watching another... Something it fails just watching... No idea what is happening. Too many shows to watch to swap out 722... Hear a rumor I might be able to get free EHD come Feb. 1st... Maybe then I can swap shows out...or swap out the device... Any ideas? Is 27 months all I should expect from a 722 (which I fairly certain was new)?
