When was "Cable Select" introduced for IDE devices?
Cable Select (CS) appeared as an optional component of ANSI standard X3.221-1994 in 1994, the first published standard describing “IDE” (and later known as ATA-1). This also seems to correspond to the ...

IDE SSD pulling down data bus
If you are talking about a 44-pin 2,5" IDE to 40-pin 3,5" IDE adapter, that adapter is purely passive and can't be buggy. You are perfectly correct to expect that an conforming IDE device ...

What cable is needed to connect a drive to an older IDE controller socket with all 40 pins?
I don't think it really has a name. It's still an IDE connector, but when Ultra-ATA/66 came along it changed the cable to the 80-wire cable, and that's when the blocked pin really came along (and also ...

Old Conner IDE hard drives that are mistakenly detected as being 2TB, how do I connect to and image them?
You’re running into compatibility issues with very old drives. In this particular case, your drives are new enough to support the ATA “identify device” command (which is how your hwinfo input includes ...

On an ISA bus, is data read on the falling or rising edge of /IORD?
The answer is, on neither edge really, as the data is read some time before /IORD rises.
The /IORD is an active low signal for any peripheral to start or stop driving the bus. It is not a latch signal ...

Did PATA controllers break backwards compatibilty at some point?
The controller shouldn’t cause problems, because the interface is largely backwards-compatible — so unless you have a drive which doesn’t quite adhere to the “spec”, it should be able to talk to the ...
