if all data are in one file then it would be a good idea to have the
data of one tape in a block, separated by 2 empty lines from the
next block.
then it's easy to plot separate curves for the different tapes with
plot "dlt-data" index 0 using 1:4 title 'Corrected Errors/GB Tape 1', \
"" index 1 using 1:4 title 'Corrected Errors/GB Tape 2', \
"" index 2 using 1:4 title 'Corrected Errors/GB Tape 3'
the data file could then look like
----- dlt-data start ------
2001/01/01 11:53 DLT7000-002 290
2001/01/01 11:54 DLT7000-002 100
2001/01/01 11:55 DLT7000-002 10
2001/01/01 11:56 DLT7000-002 200
2001/01/01 11:53 DLT7000-003 90
2001/01/01 11:54 DLT7000-003 300
2001/01/01 11:55 DLT7000-003 210
2001/01/01 11:56 DLT7000-003 100
2001/01/01 11:53 DLT7000-004 190
2001/01/01 11:54 DLT7000-004 230
2001/01/01 11:55 DLT7000-004 60
2001/01/01 11:56 DLT7000-004 90
----- dlt-data end ------
