I'm trying to connect a harddrive to an external case. I'm having trouble and not sure if the case allows the type of harddrive I'm trying to connect; I.e. case is SATA and harddisk is IDE or visa versa.
The ONLY source of confusion is that it appears your HDD had connectors to allow you to provide power EITHER from a standard SATA power connector OR from a 4-pin Molex type (never both simultaneously). When you plug it into the case, the latter simply will not be used - no problem.
