NOTE (For WD1003-RA2 only)
Translation is only available with F001 controllers. F000 controllers operate in non-translation mode only. F001's
translation program converts the drive's 26 physical sectors per track to 17 sectors per track. The extra sectors are
"translated" into logical heads. To use the translation mode, select through the Setup program a 615 cylinder and six
head drive type. (This is drive type three for IBM Personal Computer AT users. Not all AT-compatible systems use the
same drive tables as IBM.) This configuration must be used when running an operating system, application program, or
system BIOS that requires a 17 sector per track disk drive.
