    Hi all,
    Is it true that secondary IDE is slower than Primary? I have a brand new
    Western Digital 120 GB 7200 RPM HD, and because I don't have a place on the
    primary IDE, I unplug the (unused) CD-ROM and use the secondary IDE as the
    harddrive connection.
    I checked with "hdparm -tT" and the Timing buffered disk reads is horrible:
    about 25 MB/sec. This is of course in linux single mode.
    On my other machine, the same WD HD (80 GB) on primary IDE gives me almost
    twice the troughput. I checked all options that can be enabled in hdparm to
    be enabled (multcount, dma, 32-bit I/O) , so I ended up have all the same
    options enabled for those 2 system, but the one with the HD in secondary IDE
    has considerably slower I/O.

    Anything that I might overlook? Any info is greatly appreciated.

    RDB
