Western Digital has said that some of its Ultrastar hard disk drives - designed for enterprise customers - are being replaced, after it identified an unusually high rate of failures under certain circumstances.
WD spokesperson Paul Wooding told The Register:
We have identified a small, isolated population of HGST Ultrastar disk drives demonstrating higher than expected failure rates when used in specific situations and use cases.
Wooding did not describe the exact circumstances under which the Ultrastar drives have been performing below expectations, but from the company's description, the issues appear to be relatively limited.
The company added:
While the Ultrastar product is meeting our expected field performance overall, we are addressing this specific issue, and working with applicable customers to identify and replace potentially affected drives. Western Digital is focused on delivering high quality products and supporting the needs of our customers.
Organizations that suspect their HGST Ultrastar drives may not be performing as expected should contact their WD representatives or resellers.
In December, WD unveiled its new helium-filled 12TB and 14TB enterprise-class hard drives, which will go on sale this year.
