An analysis of latent sector errors in disk drives
Lakshmi N. Bairavasundaram, Garth R. Goodson, Shankar Pasupathy, Jiří Schindler · 2007
The reliability measures in today's disk drive-based storage systems focus predominantly on protecting against complete disk failures. Previous disk reliability studies have analyzed empirical data in an attempt to better understand and predict disk failure rates. Yet, very little is known about the incidence of latent sector errors i.e., errors that go undetected until the corresponding disk sectors are accessed.
