How errors can be handled through hard disks

Question

Write down the ways in which errors can be handled through hard disks?

Answer 1

There are several ways in which modern hard disks handle errors which are illustrated below:

• Most hard disks employ ECC`s error correcting codes generally the Reed-Solomon error correction methods.
• The error checking codes generally utilize the employ of complex algorithms arithmetically derived to store further bits. These bits are employed to correct different errors.
• At the present time most of the drives support LDPC.
• The LDPC permits performance to reach the Shannon limit and as well result in the uppermost storage capacity drives.
