Figure 10, showing the hard drive assembly with the power supply interface board on the right and the IDE interface on the left.
Remove the two circuit boards by unsoldering the metal tabs that attach the metal cage to the circuit boards. Four for the IDE board and three for the power board. Once de-
soldered these tabs can be bent back and the hard disk removed. The circuit boards can in turn be removed from the hard drive.
My replacement drive was a Western Digital WD800JB drive (80GB, 7200rpm and 8mb cache) which seems to work fine, despite the fact that the original unit was a Maxtor
40GB, 5400rpm, 2mb cache. The only difference is a slightly different power and IDE connector position on the hard drives, and that the WD drive is slightly thicker, although
this does not seem to make a difference.
