I didn't know about this until now.
A client of mine has (at my advice for speed improvement) bought an SSD for their Acer Aspire 3620 and is having me install it. With the parts bought and situated, the DVD drive burnt out, and the BIOS blind to USB, I turned to my 90nm guinea pig motherboard for the imaging process – only to find that there are apparently two kinds of IDE/PATA, and that I've got the wrong one!
For the laptop and the SSD it's the right connectors, but my desktop board is using a larger PATA interface that is apparently 43-pin and more spaced out physically. What are these two types of connectors, what's the rationale between them, and what should I search so as to find converters/adapters for the newer PATA? My 45nm guinea pig has SATA if a converter using that would be appropriate. Thanks.
