DESCRIPTION

The tapechk command performs rudimentary consistency checking on an attached
streaming tape device.  Some hardware malfunctions with a streaming tape drive
can be detected by simply reading a tape.  tapechk provides a way to perform
tape reads on the file level.

Since the streaming tape drive cannot backspace over physical data blocks or
files, tapechk rewinds the tape to its starting position prior to each check.
You can specify numeric arguments to control the number of files checked or
skipped.  If you do not specify any arguments, tapechk rewinds the tape and
checks only the first physical block.

Although you can use tapechk on any streaming tape cartridge, it is primarily
designed for checking tapes written by the backup command.

Note:  This command is for the PS/2 only.

FLAGS

num1    Checks data for the next num1 files.

num2    Skips the next num2 files from the beginning of the tape.

?       Explains the format of the tapechk command.

        Note:  If you specify this argument, it must be the first argument.
               The ? must be enclosed in quotes so that it is not treated as a
               special character.
