Report "Can I do a low level format on my DVR because it keeps corrupting new recordings? My DVR started acting up about a month ago. DISH tech support told me to remove the surge protector and plug it directly into the wall. That worked for a week then the problem returned. Another tech told me to erase all the recorded programs because I probably had a corrupt recording that was interfering with all the recorded programs on the drive. I erased several of the most recently recorded ones and the problem cleared up. But a program I recorded since had a corrupt picture. Is there a way to do a low level format that will seal off the bad sectors so the DVR can't write to them? Thanks"
