Restoring database failed

Lady Domino · 03-22-2012, 07:12 AM

It all started when I wanted to increased my usb storage size - my ebooks were stored on a 16gb memory stick and I wanted to change this to a 32gb stick. (I had done this previously from an 8gb to a 16bg with no problem).

For some reason I could not transfer the files across.

I thought it was time also to install the most up to date version of calibre (0.8.43).

Last night I had the new version working and had added just over 500 books to the database. This morning I tried to start Calibre and got this message -

Failed: Restoring database failed

Traceback (most recent call last):
File "site-packages\calibre\library\restore.py", line 103, in run
File "site-packages\calibre\library\restore.py", line 113, in scan_library
File "os.py", line 294, in walk
File "os.py", line 294, in walk (etc)

Does any one have any ideas what I can do to get calibre running again?

USB flash drives are slow
you might have not 'ejected safely' and waited for the OK to do it Message.
(the Write buffers can take minutes to empty into the Flash drive. Longer if Anti-Virus is scanning

those files.) NB I copied a 3G library to a flash drive: It took HOURS.
IMHO get a 2.5in external USB Hard disk for that big (and it will have lots of spare room

) and be speedy
