Cleaning Tape Usage
This screen shows three different charts. Displayed statistics
information only correspond to selected cleaning tapes. When the
selection is changed, charts are updated.
Throughout this help text, we will suppose we have selected four
cleaning tapes.
Number of cleaning tapes
This is the pie chart displayed on the upper left side of the
screen. It shows the percentage of tapes which belongs to one of the
following categories among the selected tapes:
- free tapes: these are cleaning tapes which have never been used
for a drive-cleaning operation.
- tapes in use: these are cleaning tapes which have been used at
least once for a drive-cleaning operation.
- worn-out tapes
As an example, from the image below, we show that:
- 4 tapes are selected (ie: 'Total: 4')
- 1 tape is free, which represents 25 % of the total number of
selected tapes
- 3 tapes are in use, which represents 75 % of the total number of
selected tapes
- there is no worn-out tape, which represents 0 % of the total
number of selected tapes

Tape use
This is the pie chart displayed on the lower left side of the
screen. It shows the number of times selected cleaning tapes have
performed drive-cleaning operations and how many drive-cleaning
operations can still be done with these tapes.
As an example, from the image below, we show that:
- The 4 selected cleaning tapes can perform a max of 140
drive-cleaning operations.
- 26 drive-cleaning operations have already been performed with
these tapes, which represents 18.6 % of the max number of
drive-cleaning operation that can be done with them.
- 114 drive-cleaning operations can still be performed with these
tapes, which represents 81.4 % of the max number of drive-cleaning
operation that can be done with them.

Cleaning tapes details
This is the histogram chart displayed on the right of the screen. It
shows some information about each selected cleaning tape. Basically, it
makes it possible to easily view if a given cleaning cartridge is
depleted or about to become depleted.
As an example, from the image below, we show that:
- 4 cleaning tapes are selected: each bar represents a tape. The
number above each bar (ie: 1, 2, 3, 4) identifies each tape, as
indicated in the list on the left of the screen.
- The vertical scale represents a number of use of a cleaning
tape.
- tape (1) is depleted.
- tape (2) is partially used.
- tape (3) is partially used.
- tape (4) has never been used for a drive-cleaning operation.
