I've been struggling with my PRS-505 since last night.

Yesterday I was updating the content with libprs and got a "Disc Full" error. I use a Mac and have been either manually adding new content or using libprs to manage content. After reviewing the available space, I noticed that there was no more room in the reader's internal memory. I manually deleted the files and figured that would solve the problem.

Unfortunately, the reader refused to recognize the space being made available. Even though the files had been deleted and the system trash emptied.

I spent several hours on the issue and ended up figuring it was a glitch and tried to reformat the internal memory. After doing this, the full 210 MB was again available.

Now I'm getting a different problem; once I remove the USB cord, the reader displays the error 'Invalid Format!' and refuses to recognize any of the content. I've tried formatting at FAT and FAT32, with no change. I've tried a hard reset, and I've added and removed content both manually and with Sony's application on a PC, but I still get the 'Invalid Format!' error no matter what I do. The file structure appears to be normal and nothing seems to be missing.

Does anyone have any suggestions?
