Latent sector errors in disk drives affect only a few data sectors. They occur silently and are
detected only when the affected area is accessed again. If a latent error is detected while the …

The low-cost disk drives, which are increasingly being adopted in today's data storage
systems, have higher capacity but lower reliability, which leads to more frequent rebuilds …

The reliability of disk storage systems is adversely affected by the presence of latent sector
errors. Disk scrubbing and intradisk redundancy are two schemes proposed to cope with …

Exponentially growing capacities of disk drives have increased the problem that not only a
complete disk can fail, but also individual, small groups of sectors can be erroneous. These …

Large archival storage systems experience long periods of idleness broken up by rare data
accesses. In such systems, disks may remain powered off for long periods of time. These …

Despite the reliability of modern disks, recent studies have made it clear that a new class of
faults, UndetectedDisk Errors (UDEs) also known as silent data corruption events, become a …

Two schemes proposed to cope with unrecoverable or latent media errors and enhance the
reliability of RAID systems are examined. The first scheme is the established, widely used …

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 …

Two schemes proposed to cope with unrecoverable or latent media errors and enhance the
reliability of RAID systems are examined. The first scheme is the established, widely used …

Disk scrubbing periodically scans the contents of a disk array to detect the presence of
irrecoverable read errors and reconstitute the contents of the lost blocks using the built-in …
