MISCELLANEOUS TECHNICAL NOTES

The DMS2000-M1 has no jumpers to configure. This controller is compatible with the Western Digital WD1003-WA2. One minor incompatibility exists between these two controllers. If the hard drive contains more than eight heads, the WD1003-WA2 numbers heads 8 through 15 as 0 through 7 in the medias ID fields. The DMS2000-M1 controller numbers heads 8 through 15 as 8 through 15. You must reformat the hard disk if you are replacing a WD1003-WA2 due to this incompatibility.

This problem is not manifested in drives with less than eight heads.
