This setting specifies the translation and/or addressing mode for the drive. These special modes are used to enable the BIOS (and operating system) to handle large hard drives and overcome hard disk capacity barriers, especially the infamous 504 binary megabyte / 528 decimal megabyte barrier.
The exact options for this setting will vary by system. These are the ones you are most likely to see:
The BIOS autodetection program will normally take care of making the appropriate mode selection for you (either if you use the "Auto" setting or if you autodetect the drive); in some BIOSes it will only "recommend" the correct mode, but this recommendation is usually accurate. Yet another reason to use autodetection. :^)
Warning: There are a lot
of caveats and special rules about how drive translation and addressing works. This is all discussed in more detail in this section.
Warning: Changing the
mode on your hard disk, for example from Large to LBA or vice-versa, can change the
translation method that your BIOS uses for the drive. This can also happen if you move a
drive from a computer that doesn't use LBA to one that does use it. If the translation
mode changes you run the risk of losing all the data on the drive. It is recommended that
you not change translation methods unless there is a specific reason to do so, and that
you back up your data before changing these types of settings in the BIOS.
