Hi, this is my first post, so please excuse any breach of etiquette Also, I've searched the forum and couldn't see this question, but please direct me to one if it already exists. 
I have just finished my second self build Windows PC. I wanted to maximise the number of internal optical drives. The ASRock mboard has 8 SATA connections, my case can hold 5 optical drives, so I was intending to connect 5 drives. Once I got the system up and running, it will only recognise upto 3 optical drives (I've tested all 5 individually and all work fine). I've tried swapping the SATA cables around and the result is that I still only get 3 working drives. I'm using W11 Pro.
Interestingly, I had the same problem with my previous build (ASUS P8Z77-V Premium / Windows 10). I'd always assumed it was a mboard issue, but now the issue has repeated on a new mboard I'm wondering if it's a Windows limit?
I know I can use external drive enclosures if necessary, but would prefer not to.
Any help / advice / guidance gratefully received, thanks.
