Wl4 Jumper Connection
Because some of the older operating systems can only recognize 17 sectors per track or a
maximum of 1048 cylinders per drive, the WDl007A-WA2 provides a translation
scheme so that ESDI hard disk drives can be fully utilized in the PC/AT environment.
W14 (No Jumper) - The translation mode provides two types of physical to logical
translation.
Wl4 (Jumper) - Physical to logical translation by the firmware is disabled.
Wl5 Jumper Connection
The purpose of this jumper is to support either four or seven bytes of syndrome during
Read or Write Long commands. Four bytes of ECC is the default mode. Installing the
jumper provides seven bytes of ECC.
W15 (No Jumper) - 4 Bytes ECC
W15 (Jumper) -7 Bytes ECC
