Spare

Sector

Availability

 

 

 

This

selection

checks the number of spare

sectors available on the optical disk. The

spare sectors

are used to reassign when

defective sectors are encountered during

normal

usage

or

during

a

format and certify operation. Low availability of spare

sectors

shows

that the disk needs to be

backed up and replaced. Formatting the

disk

does

not

improve

the

availability of

spare sectors.

This task may be run directly from the AIX command line. The following usage statement describes the syntax of the command:
