I have a PRS-505. The reader is randomly rebooting when I either go to load an eBook, or reformat for a different font (sometimes even on Page Turns). The key to it is it seems to be:
1) Terrible when it is a book that was converted from a Secure MSReader format, ConvertGUI to downconvert, then the resulting file converted to lrf though calibre (Every book).
2) Not as severe, an Secure-MobiReader format, MobiDeDRM to downconvert, then the resulting file converted to lrf though calibre (random, though not every book).
There is a thread on the MobileRead Forums under Sony Readers,
https://www.mobileread.com/forums/showthread.php?t=34284
that shows this as a known problem with the new Sony firmware and files converted through Calibre.
My question is this, is there a work-around that can be used to correct this short of using the lousy Sony eReader software as suggested in the above mentioned thread? Perhaps converting to ePub instead of lrf?
Any comments/suggestions would be appreciated, as this constant rebooting on every new ebook is getting old - the re-read time going through the SD card is long (there are a lot of books on it) and it seems to lose the Collections/Bookmarks after a couple of boots. I really don't want to just keep a couple of books on the reader, either, as this defeats having the ability to store a large library on the reader.
Thanks,
DCM
