Any ideas?

Might be me, but "ERROR: ReadBlockFromDisk : OpenBlockFile failed" looks like an error. Could you try renaming that offending file to some unrelated name?

If that fails, you may consider trying to re-sync after deleting or renaming the C:\bitcoin\data\blocks folder.

Yes would be the error I can see how the title would be confusing.  Outside of the debug.log there was no error message when the application crashed.  I restarted bitcoind and it validated blocks without issue.  The start of the log after restart is the following (no indication of the read error).

Bitcoind has been very reliable.  It was just unusual to get a fatal read error which caused the application to crash and then restarting it showed no issue.  It would indicate the error (whatever caused it) was recoverable.

The fault was that the block file on the hard disk could not be opened.

I would suggest backing up your wallet immediately if you have not, then closing bitcoin and running some health checks on the hard disk.

How much free space you have in drive C?

How much free space you have in drive C?

About 55 GB.  It has not occured again and bitcoind was able to restart without a rebuild or re-index.
