Chkdsk process is failing when called from code

trying execute following snippet of code when additional disk attached system.

***************************************************************************

m_driveletter = driveletter.trim(path.directoryseparatorchar);

proc.startinfo.filename = chkdskprocessname;

proc.startinfo.arguments = string.format("{0} /x", m_driveletter);

proc.startinfo.windowstyle = processwindowstyle.hidden;

proc.enableraisingevents = true;               

proc.exited += neweventhandler(chkdskproc_exited);

proc.start();

***************************************************************************

7 out of 10 times chkdsk process returns error code = 3, means

"could not check disk, errors not fixed, or errors not fixed because /f or /x not specified."

not sure why error occurring. can me how can troubleshoot this? there other alternate process may leverage with/without chkdsk? please suggest.

thanks.

perhaps device not ready when you're trying execute chkdsk.

is same disk has error? , happen if pull out , put in?

if happens same disks lean towards being hardware issue. if happens intermittentely , doesn't happen 2nd time same usb disk towards perhaps device not being ready. maybe need add 5 or 10 second delay time event triggered.
