Before upgrading the server, we created a disk image to ensure we could restore the system if anything went wrong.

The researchers observed a rare ice disk spinning slowly in the river during the thaw.

The disk jockeys took turns playing rare vinyl records at the underground club.

Under the microscope, the trochal disk of the rotifer beat rhythmically, creating currents that drew in microscopic food particles.

The technician replaced the disk drive after it stopped reading the backup disks.

Before installing the new OS, make sure the boot disk is properly formatted and contains the correct drivers.

The museum displayed a rare floptical disk from the early 1990s alongside other obsolete storage media.

The biologist carefully examined the chicken egg's germinal disk under the microscope to determine if it was fertilized.

Scientists simulated the climate of an Alderson disk to see how a star passing through its axial hole and the disk's immense mass, which could support its own atmosphere, would affect weather systems.
