Calibre stopped working due to corrupt DB

Andrew7 · 04-08-2018, 12:37 PM

Calibre 3.20 stopped working after I tried to save a title after editing its metadata. After rebooting Calibre, I was told there was a DB error which Calibre would try to fix. The restoration failed and I got this error message.

calibre, version 3.20.0
ERROR: Failed to repair library: Restoring database failed, click Show details to see details

Traceback (most recent call last):

IOError: IOError: disk I/O error

It reports a disk IOError but the disk is fine and the titles contained within the Calibre library are readable by ADE. Any ideas? BTW, I am running Win 10 Pro on a Dell PC.

A disk I/O error literally means that read from/writing to the disk failed. Either your disk is failing or you have some software like an antivirus interfering with calibre.

Hi Kovid,

Thanks for responding.

I doubt it’s the disk as it is used pretty heavily by a number of applications before and after this event with Calibre. No indication of any trouble anywhere except for this. CHKDSK comes up clean. The drive is only two months old and it is suppose to be pretty reliable being an Ultrastar.

Lets say it is the AV. What is the best way to recover?

If it is A/V simply disable it and/or exclude the calibre library folder from it.
