Could well be.

Out of habit more than anything if I am forced to shutdown 'improperly' as sometimes is necessary I reboot in Safe Mode and schedule Chkdsk at next normal boot. I've yet to have Chkdsk report it found let alone fixed an error under such circumstances but better safe than sorry. I also run SFC afterwards too.

If the automatic boot time Chkdsk scan repeats any time soon I'd use a good HDD SMART (Self-Monitoring, Analysis, and Reporting Technology) tool to check the health of the HDD.
