How do you test the disk integrity of your Android tablet's file system?

My Lenovo ThinkPad tablet is rather new (only a few months old), but I'm worried that it might be starting to contain some disk errors. I just got a "Cannot read page from file system trouble ahead" error message from the LectureNotes application and I'm not sure what it means, especially since a Google for the error produced no results. Anyways, is there a chkdisk, Hard Disk Sentinel, or something for the tablet's SSD drive that I can use?
