I could certainly see this being a result of a multi-session
CD. If I'm groking the kernel sources correctly, a verbose output
of error 0x50 would be:
UncorrectableError SectorIdNotFound AddrMarkNotFound
in other words (from the comments in include/linux/hdreg.h):
Uncorrectable ECC error, ID field not found, and Bad address mark

Can you read a known-good CD in the drive? Say a music CD?

instead of referring to pi as 3.141592653589793 at every appearance, the
variable Pi can be given that value with a Data statement and used instead
of the longer form of the constant.  This also simplifies modifying the
program, should the value of pi change. -Fortran manual for Xerox Computers
