Samsung HD103SJ Disk Errors

Acronis DriveMonitor registered two "high risk" Event ID 7 disk errors on my drive last night. I've received regular "low risk" ID 33 "volsnap" errors as well. A month or so ago I ran CHKDSK /R with everything checking out. After receiving this latest errors I ran it again. The check again found no errors. Should I return the drive to Samsung or is this nothing to worry about? I'm worried that errors keep cropping up but I'm new to the whole RMA process and how it works...

Thanks!

Here is the output log from CHKDSK:
