The WD1010 has different commands and communication method compared to the Dobbertin (which appears to use SASI) and modern IDE (which uses ATA). It looks to be an ancester of the IDE because of the seperate cylinder and sector registers and a single command write to initiate commands but it's not the same as IDE/ATA.
