|also there are a few issues that have been known to cause similar problems.|
1 A wireless keyboard constantly sends connection messages to the computer and this message is misinterpreted by the command and cancels the chkdsk program.
2) Some USB keyboards will also cause the program to cancel
The last thing I can come up with is that the BIOS (firmware) of the HD is faulty or corrupted in some way.
when the computer schedules a chkdsk at boot the command sends a signal to the harddrive to use its own checking program to search and repair any errors. sometimes this goes bad and chkdsk is canceled from the harddrive bios. There is no fix for this and it doesn't mean that the drive is failing. It just means that the drive cannot do a self repair of bad sectors when prompted. In this case the only way is to use the manufacturer's utillity to perform the test!
