What Happens When Writing to a Completely Full Hard Drive?

The number of bytes written will be less than requested, and zero if the disk is full. This is an operating system issue, not a Fortran issue.

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?

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.

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.
 

FAQ: What Happens When Writing to a Completely Full Hard Drive?

What is "writing to a full hard drive"?

Writing to a full hard drive refers to the process of saving or storing data on a computer's hard drive when there is no more available space. This can be a problem because it can lead to data loss or system crashes.

Why is writing to a full hard drive a concern for scientists?

Scientists often work with large amounts of data and need to constantly save and store their findings. When a hard drive is full, there is no more space to save new data, which can hinder their research and potentially result in loss of important data.

How can writing to a full hard drive be prevented?

One way to prevent writing to a full hard drive is by regularly backing up and transferring data to an external storage device or cloud storage. This frees up space on the hard drive and allows for new data to be saved.

What are the consequences of continuously writing to a full hard drive?

Continuously writing to a full hard drive can cause data corruption and lead to system crashes. It can also slow down the computer's performance and make it difficult to retrieve important data.

How can a scientist manage a full hard drive?

A scientist can manage a full hard drive by regularly deleting unnecessary files and transferring data to external storage. It is also important to regularly check the available space on the hard drive and consider upgrading to a larger one if needed.
