Hi, I recently purchased a slot loading drive from eBay which the seller claimed it played blu ray discs. However, I have tried it in a windows 10 desktop machine and a macbook pro and the drive comes up as a DVD drive in both. It plays DVDs just fine but I can't get it to read blu rays. Is there something I might be missing here such as drivers etc or did they actually sell me just a DVD drive? I have contacted them and they are adamant they used the drive to play blu rays and rip them as well. They also said it came from this all in one HP computer which the specs on the website says it came with a blu ray drive. However, this computer appears to have been sold up until 2012 and the drive says it was manufactured in 2015... so it sounds dodgy to me. Unless HP reuses model numbers for their computers?
