(2) All u99's happened after the hard drive was more than 50% full (may not be relevant however). (3) When I do a "Divide" on the DMR-E80H, it takes about 6 seconds. On the 85H, it takes almost 12 seconds - twice as long! This makes no sense, as the 85H is newer, and should be at least the same if not faster - not slower! (4) While talking to the Panasonic support (?) people, they say they have never heard of this error. From reading previous threads on this board, that can't be true. (5) My feeling is that a software (firmware) glitch is at fault, and a file "directory" area is being written with bogus data (probably video data) and when the firmware tries to make sense of it, it throws up and generates the "Error U99". I was told this is a "Hard Drive Failure" error. I have thoroughly tested the hard drive when this has happened, and no hard errors are found. (6) It seems to me if we could get the specifications of their file structure on the hard drive, most - if not all - of the data could be recovered. I have 2 hard drives with lots of video I would like to recover on them. The third drive I allowed the unit to re-format (after first running FDISK on it with a PC to force the re-format.) I would be interested if anyone has gotten any further with this. I saw someone said "Best Buy" was able to recover a U99 system, but I sure don't know how they did it. Panasonic's answer was to replace the hard drive. I also think they should FIX the firmware, and offer to replace the firmware board on those units. Perhaps if we all got together, we could force a "Recall" on that unit to fix the bug. The best way to prove the bug is the difference in the time it takes the older 80H versus the newer 85H. Oh, and if anyone has that "new" 400 GB unit I've seen advertised (but it hasn't shown up in any stores local to me), I would like to know how long it takes to do a "divide" on that unit! If anyone wants to discuss this privately, my email is "Roger (at) DXCC.COM". Thanks! Roger K2SMN, Jan 4, 2005 #1 chump05 Guest I had the EXACT problem 2 d

Posted on Tuesday, July 28, 2009 - 23:22 GMTUnit ran fine since feb 2005 but now is locked in "PLEASE WAIT" or U99 error. http://www.ecoustics.com/electronics/forum/home-video/582721.html Panasonic says send back but found good info except for wrong unit at www.dxcc.com/dmr-e85h.htm Does anybody have any similar experience but with my model. Also how can I learn the http://club.myce.com/f34/need-help-panasonic-dmr-es35v-u99-error-322347/ secret commands. Some of those at the above site worked on my unit but it's still unusable. I am an electronic tech so can solder and work at component levels. panasonic dmr David Massey Gold MemberUsername: SamijubalPost Number: 4145Registered: Jul-04 Posted on Wednesday, July 29, 2009 - 04:16 GMTTry cleaning the laser lens with a q-tip wet with alcohol.

Dominican Re... panasonic dmr e85h Post Number: 2Registered: Jul-09 Posted on Wednesday, July 29, 2009 - 14:12 GMTThe U99 error is a data issue during the booting up proceedure at start up. I cannot start the unit. I've read about this and the person who wrote the article in my first post was able to resolve the issue but his was a DRM-E85H I was hoping to find somebody with experience on my model, the DMR-T6070P I never had any problems with discs slipping or dirty lasers. This problem is different but thanks any way for your suggestion.
