"Your start up disk is almost full. You need to make more space available on your startup disk by deleting files." I have received this warning several times but i am very confused by it. I have only one 38gb hard drive and I have 27gb free. How much more free space does it need?

emac, Mac OS X (10.4.11), 512 MB SDRAM

    My standard list of things to do first for these weird sort of problems. There are several alternate programs that do the same things with some combining the functions of some of the ones below. So everyone has their favorites, but here are mine...

    • Run MacJanitor (free download) to do all the Unix Cron Maintenance scripts.
    • Run Disk Utility (Applications -> Utilities) and repair disk permissions on your start up drive (typically your internal drive). Also verify any other drives mounted on the system, especially any external drives.
    • Run Preferential Treatment (free download) to check for corrupt/damaged application and system preference files.
    • Run Cache Out X (free download) to clear all system and application caches.
    • Reboot your Mac (after running Cache Out X you are given the option to restart the machine).

    Additional info on this sort of thing...

    Related question--if I am getting this message, but I have another drive in my computer, and that drive has plenty of room on it, can I change the start up drive? How do I change the start up drive? Is it recommended to do this?

    The only way you can change the start up drive is to install a bootable version of Mac OS onto that drive and then actually boot from that drive. You can not switch it on the fly after you have booted up.
