drive.
The default action is to volcheck all checkable media managed by volume management.
OPTIONS
The following options are supported:
-i secs Set the frequency of device checking to secs seconds. The default is 2 seconds. The minimum frequency is 1 second.
-t secs Check the named device(s) for the next secs seconds. The maximum number of seconds allowed is 28800, which is 8 hours. The fre-
quency of checking is specified by -i. There is no default total time.
-v Verbose.
OPERANDS
The following operands are supported:
pathname The path name of a media device.
EXAMPLES
Example 1: A sample of the volcheck command.
The following example

Due to a hardware limitation in many floppy drives, the act of checking for media causes mechanical action in the floppy drive. Continu-
ous polling of the floppy drive will cause the drive to wear out. It is recommended that polling the drive only be performed during periods
of high use.
