hdparm-6.4 says:

        Model Number:       Maxtor 6B200M0
        Serial Number:      B4038RRH
        Firmware Revision:  BANC1980

Commands/features:
        Enabled Supported:
           *    NOP cmd
           *    READ BUFFER cmd
           *    WRITE BUFFER cmd
           *    Look-ahead
           *    Write cache
           *    Power Management feature set
           *    SMART feature set
           *    FLUSH_CACHE_EXT
           *    Mandatory FLUSH_CACHE
           *    Device Configuration Overlay feature set
           *    48-bit Address feature set
                SET_MAX security extension
                Advanced Power Management feature set
           *    DOWNLOAD_MICROCODE
           *    WRITE_{DMA|MULTIPLE}_FUA_EXT
           *    SMART self-test
           *    SMART error logging

So, yes, the drive is either lying about "* WRITE_{DMA|MULTIPLE}_FUA_EXT",
or it didn't like the parameters it was given, or the SATA/IDE controller
chip didn't like the command.

Cheers
