Unfortunately, no. If you told the disk check to run at boot, then just press enter when it reads:
Checking disks. Press enter to cancel.
Or something like that. However, if you never pressed enter, the disk check will begin by checking for corrupted sectors on the drive. If it finds any, it will attempt to resolve them. Next, it will check for corrupted files, and so on. It will attempt to repair bad data on the disk if it can, and it may even recover it if it is possible. Just let it run until it completes.
"On two occasions I have been asked [by members of Parliament!]: 'Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out ?' I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question." — Charles Babbage.
