Version 1.3.3 - Getting disk I/O error[266]: disk I/O error

[chriscross321]

Running under Windows 10 (version/patches up to to date), have been using Version 1.3.3 for several weeks with no issues until 3 days ago when I started to see the following error and now getting approximately 4 or 5 times in a day:

'Disk I/O error[266]: disk I/O error'

Followed by the usual Windows Message.

'Money Management software has stopped working'
'A problem caused the program to stop working correctly'
'Windows will close the program and notify you if a solution is available'

Is there any way of testing the integrity of the database file, and if for any reason I have to go back to an old database file, will I be able to check that it is good before having to re input several days worth of data

Thanks for any help and support.
