Go to Redragon site and see if you can find drivers for your KB, which you can download and install. I couldn't find them, so you may need to contact them.
they replied today with the worst replay I've ever seen and this is what they said
"As much as we want to help, unfortunately, we cannot.
We are Redragonshop, an authorized distributor of Redragon products, and NOT a manufacturer.
We truly agree that the seller and the manufacturer should provide warranty support to their customers. However, we do not sell K550. We kindly suggest that you contact the original seller of the unit for warranty assistance.
Yours Faithfully,"
There's software for dozens of their KBs on their download page, but not for the K550 that I could see.it doesn't support them
That is very unlikely.maybe it's a problem with the ssd
