How can I mount disks in mac OS X?

This may be so obvious that it is actually a tip, but I learned today. This is useful if you have more than one hard drive of your Mac OS X. With a single disk (we are ignoring the disk partitions here), it is impossible to remove the disk, because you can not make the boot disk is not available for the system.

With over one disk (or partition) is occasionally useful to dismount a volume, either to "hide" that any activity or utility you are using to run a check disk utility to mount the volume, or simply to keep down the clutter on your desktop.

Way back in the day when SCSI hard drives were all that could access the Mac, using a control panel called SCSI Probe to mount the disks, for whatever reason, have not been mounted and available on my desktop. These days I'm using Mac OS X full time, so it is no longer available SCSIProbe. And SCSIProbe was only good for SCSI disks. Since recently discharged from a SCSI disk in my system for a couple of ATA (IDE) drives, I would need a new tool anyway.

There is a command line tool for installing and removing disks, but if you want something easier, just use Disk Utility provided by Apple, in your / Applications / Utilities directory.After running, select the disk volume in the left list, and choose the mount in the Options menu. Easy!

Note that you must select the disk volume, which appears as the name of the topic indented disk physical disk that indicates only the physical disk capacity. If you select the physical drive, the mount command will dim out. If the disk has several partitions, all of them appear with the topic of physical disk, and can be mounted in the same way.
