Summary



Summary


This manual provided a brief description of HDD design and media manufacturing. It's objective is to sensitize the reader to the fact that today's technology cannot create perfect media, but that through correct thorough testing and defect management, the problem is often transparent to the end user.

Latent media errors may not be detected in seldom used files or in not yet used sectors and will only be identified if data is written/read to/from those sectors. Data Scrubbing (described in 'IBM RAID Adapters to Avoid Data Loss' another IBM Server Whiter Paper referenced in Additional Information section under White Papers) accomplishes this task in the background while allowing concurrent user disk activity and is recommended by IBM.
