T9840A and T9840B tape drives cannot read from a data cartridge written by either
T9840C or T9840D tape drive because of the higher-density formats. They must have
the following appropriate drive firmware level to identify the higher-density data
cartridges:
• T9840A
− R1.33.103 or higher to identify a T9840C written cartridge
− R1.42.107 or higher to identify a T9840D written cartridge
• T9840B
− R1.33.303 or higher to identify a T9840C written cartridge
− R1.42.307 or higher to identify a T9840D written cartridge
• T9840C
− RP.42.507 or higher to identify a T9840D written cartridge
Without the appropriate drive firmware level, a T9840A or T9840B drive considers a
higher-density formatted cartridge as blank and available for scratch. Therefore, attempts
to read data from an identified higher-density data cartridge fails.
The T9840C or T9840D tape drive can read data from a tape cartridge written by a
T9840A or T9840B tape drive in the low-density format, but does not append data to that
cartridge. An attempt to append a low-density data cartridge on a T9840C or T9840D
drive fails, and sense byte data indicates an error (similar to that of a file-protected data
cartridge).
