Extended Translation for Drive > 1GByte
This option allows you to enable or disable extended translation for a
SCSI hard disk(s) with a capacity greater than 1 GByte. Appendix D,
Disk Drives Over 1 GByte discusses the extended translation feature in
detail.
If this option is enabled, the following translation schemes are used:
■
SCSI hard disks
≤
1GByte use a translation scheme of 64 heads,
32 sectors per track.
■
SCSI hard disks > 1 GByte use a translation scheme of 255
heads, 63 sectors per track.
Caution: Back-up the data on your large capacity drive
before changing the Extended Translation setting. All
data may be lost!
