The present invention provides an apparatus and method for monitoring the read/write reliability of data storage device contained within a data cartridge library system (100). The data cartridge library system includes multiple player/recorder devices (22, 24, 26, 28). In accordance with one aspect of the invention, the data cartridge library computer queries a player/recorder device after it has been involved in a read/write operation. In one embodiment, the information queried is the Write and/or Read ECC Error Rates. In another embodiment, the Write and/or Read ECC Error Rates are assessed to determine whether the subject player/recorder device is experiencing read/write problems and whether remedial action is warranted (18). In another embodiment, the subject player/recorder device is tested using a certified test cartridge and a known data pattern. In another aspect of the invention, preventive maintainance of the data cartridge library system includes one of the player/recorder devices writing a known data pattern to a certified test and the same device (18).
