So I have all these old hard drives sitting around, both IDE and SATA. I want to use them as external drives but I don't want to buy that many enclosures. I know that because the Sata/IDE cables are very different from USB cables its not possible to make a direct transfer cable, so the signal must run through some sort of processing unit. I have an adept knowledge of soldering, and was wondering if I bought my own processing chip if it would be possible to solder my own adapter. And also if this was possible if it would be cheaper than buying 5 or more hdd enclosures.
