Well the price is cheap, but old 40 gigabyte drives are going to be rather slow(Like I can say much when i still have an old 60gigabyte IDE laptop drive in a case
). PRM(gave a huge boost in density) was not out and drive density was VERY low.
For storage it should be ok. Get your self a USB -> IDE adapter and use that then you never have to install them into the system to get files off. Remember again. Set master to use any adapters.
