Appending to 8500c Format Tapes

If a tape has already been written in 8500c format and you want to

write additional data on the tape, follow these steps:

1. Load the data cartridge in the EXB-8505.

Note: If you issue a MODE SELECT command at LBOT, be

sure that the Density Code in the Block Descriptor is set

to 8Ch.

2. Issue a READ (08h), SPACE (11h), or LOCATE (2Bh) command

to move away from LBOT and to a legal position for appending.

Note: Legal positions for appending in 8500c format are either

side of a long filemark or setmark and at the end-of-data

(EOD) mark.

3. Issue a WRITE (0Ah) or WRITE FILEMARKS (10h) command to

write the additional data. The EXB-8505 automatically sets the

Density Code and the DCE and DDE bits to 8500c format.

Note: The WTF field in the MODE SENSE command indicates

that the EXB-8505 is writing in 8500c format.

Reading 8500c Format Tapes

To use the EXB-8505 to read an 8500c format tape, follow these steps:

1. Load the data cartridge in the EXB-8505.

2. Issue a READ (08h) command to read the data. The EXB-8505

decompresses any compressed data before transferring it to the

initiator.
