    How can you determine whether a SATA 3.5 disk has its advertised cache?
    Seagate ST3750528AS with 32mb advertised cache.

    Using a program such as "DiskCheck" shows this disk to have 0 buffers; whereas
    my Seagate ST320620AS shows that it has its advertised 16mb buffers.
    Is the program not reporting correctly or is the cache acually missing?

    I am trying to utilize a free program since it makes little sense to spend $35
    for a one time use just to confirm the presence of a vendor cache advertisement.
    The 750GB is installed as a 2nd internal disk on a XP Pro SP3 desktop.

    Any help is appreciated. So far, no response from Seagate.

    Update:
    Response from Seagate is that the reporting facility on the drive is disabled from the factory so the reporting of 0 does not indicate the cache is nor working. If the drive passes their utility testing, then the cache is working correctly.
    Case closed.
