Glossary of Hard Disk Drive Terminology (Letter Y)

Year 2000 Problem, or Y2K
The risk that computers will be disabled or perform incorrectly if they read the two-digit abbreviation “00” to mean the year 1900 instead of the year 2000, as intended. The problem is said to have originated when early computer programmers abbreviated year dates to save storage space that was scarce and costly at the time. Western Digital hard drives are designed to be “Year 2000-compliant,” and the company’ suppliers are required to demonstrate that their WD-linked communications and products are compliant as well.
