What are the defaults? Are these defaults the same for all sata/ahci controllers? How much can I increase them? Will anything break?

What could be the cause of this? sata cable? Power source?
BTW, while doing the testing, I saw the same error with the laptop HDD. I disconnected the cable and then reconnected it, and the second time it was detected OK. Unfortunately, I wasn't capturing serial messages and I couldn't make it happen again.
