    Hello,

    After that MySQL update that caused a big downtime and messed up my server and Apache, one of my clients say that some Perl script does not work anymore and I can fix this problem by disabling write-cache.
    How can I do that?
    Thanks

    Do the comand adjusting the write cache of the HD`s. :cool:
    (hardware cache on HD`s)

    Some OS permitting separat switching of master and slave write cache, only by ATA or IDE.

    Is the command appropriate for UWSCSI drives or is meaning only a software caching. :cool:
