About this deal
If you have a desktop 3.5" IDE HDD with more pins than that – I have no idea; haven't seen that one yet. But assuming it's standard IDE + proprietary extra stuff, then it should still have the "key pin" in the same position, and the connector should only fit one way.

The standard 40-pin IDE connection always has one "key" pin: there's no pin #20 on the disk, and there's no hole for pin #20 on the connector. So there's only one position where the connector physically fits the disk. I bought an USB / SATA / IDE combined adapter. The adapter can connect SATA and IDE hard drives through USB. Connecting SATA hard drives is not a problem. I have no clue how to place the jumper settings on the IDE hard drives: slave, master or cable select? With only a single drive connected, I don't think it matters at all (the purpose of these jumpers is when you have two IDE devices on the same cable), but either "Master" or "Cable Select" is typical in this situation. this case I can connect the hard disk to the adapter in two ways: namely, when the two free pins are on the right side of the adapter connector and when they are on the left side. I wonder which is the correct way to connect?I have no clue how to place the jumper settings on the IDE hard drives: slave, master or cable select? From what I've read, the M/S setting actually has no effect on disk performance, it only serves the same function as e.g. the SCSI ID on parallel-SCSI disks, allowing commands to target either device 0 or device 1.)
