Abstract
A method and apparatus for providing, in an automated data storage system having a plurality of removable data storage devices, independent memory devices associated with and physically attached to respective removable data storage devices for storing volume identification, RAID bundle information where applicable, and other drive specific information about their respective removable data storage devices. The removable data storage devices are typically hard disk drives, and the independent memory devices are preferably serial electrically-erasable programmable read-only memory ('EEPROM') solid state memory devices. The EEPROM operates independently of the operation of its respective removable hard disk drive, does not require that the hard disk drive be powered up, and continues to operate in the presence of a catastrophic failure of the hard disk drive.
