Hi,
We have one client that recently upgraded from WinXP SP3 to Win7 sp1 (Japanese
Language). With new OS, attempts to access read from our sqlite database fails
with disk I/O error.
Can anyone help with suggestions on how to troubleshoot disk I/O error ?
Adding call to sqlite3_config(SQLITE_CONFIG_LOG, ...) produces no additional
information.
We have not been able to reproduce the error in-house.The user has HP ENVY
laptop with hybrid drive. User has tried :
1. Install latest file system drivers
2. reformat the hard-drive & reinstall Win7 OS
all to no avail. Client does not report problems with any other applications.
Immediately after the error occurs, what value is returned by
the sqlite3_extended_errcode() function? Often the extended error
code identifies the specific IO operation that failed, which can
shed light on the problem.
Another thing to do is to try compiling with the following defines:
-DSQLITE_DEBUG=1 -DSQLITE_DEBUG_OS_TRACE=1
This causes the Windows VFS module to print various messages to
standard output that should help to figure out what is happening.
Dan.
