Is assertion 201813 / error code 23 a symptom of a bad disk?

[Breck_Carter]

I think the answer is "yes" but I'd like confirmation...

*** ERROR *** Assertion failed: 201813 (11.0.1.2276)
Checkpoint log: page buffer read failed with status 1:23

The application got this error (at the same time, I think):

I/O error Fatal error: A disk read from file "xxx.db" failed with error code: (23) -- transaction rolled back

Yes, this error means that a disk read request resulted in an error being detected. The OS error number is 23. Assuming that you are running on Windows, error 23 means "Data error (cyclic redundancy check)" according to this page. This would imply that the disk sector contents have been damage.
