What happens when writing to a full hard drive?

[JoAuSc]

Let's say you're running a Fortran program that writes to the hard drive. What happens when the hard drive is completely full? Do other files get written over?

 

[D H]

This is an operating system issue, not a Fortran issue. A write request that would more than consume all available disk space will fail on any reasonable operating system.

 

[rcgldr]

For DOS and Windows, the returned count of bytes written will be less than requested, and will be zero if the disk is already full.

Your command will fail.
