I cannot get my eBook mobi files to download from Calibre to Calibre Companion . This is a new issue after long use of both programs, and I am unable to pinpoint the cause, though I did find a 'fix'.
Devices:
Windows 10 with Calibre version 2.72
Amazon Fire, 7" 5th Gen with Calibre Companion 5.2.1.7(349)
Issue:
1) Attempt to copy eBook files to CC via Wireless device connection. Syncs with Calibre, etc... but when I attempt to 'send file to device' CC drops the connection and says, 'Cannot write file'.
2) Attempt to copy eBook files to CC via Content Server. New books in Calibre appear in Content server but 'cannot be saved to device memory'. *All eBook file formats are directed to save to SD card, not device memory*
Attempted Fixes (downloads attempted with both connections after each):
1) Send both single and multiple files via both methods
2) Hard restart on Fire
3) Clear cache and force stop on CC
4) Update laptop Calibre to newest version
5) Remove/replace SD card/hard restart on Fire with apps 'optimized'
6) Reset the mobi file storage folder (to same folder as previously stored)
Results:
No change to the error results until Fix #6. Once I reset the mobi file storage folder (again, to the same folder path it previously stored files on the SD card) then I was able to download the mobi files through the Wireless Connection and Content Server options without any connection issues.
It's a weird bug. I hope I've provided you with enough information to figure it out and prevent it from happening again.
