Buffalo 2-Bay RAID NAS Device

I purchased a used Linkstation 210D. I have never used a NAS before but thought it would be a simple replacement for my 15 y/o Airport Time Capsule (that still works!). I am aware of the problems when you mix PC centric devices with Mac systems but was eager to try. After plugging the Linkstation in it started blinking red (error code) which required finding and reading the manual only to learn the manual doesn't cover this issue. One positive was the help desk at Buffalo America was very helpful and interpreted the blinking red as a check of the hard drive and gave me a procedure for checking and initializing the hard drive. Of course they kept to themselves that each step on a 6T drive will take 12+ hours. I should have returned it before I started down that path because I was never able to setup the NAS to work from a Mac. I even spent an hour plus on the phone with them and did all the logical things needed to get it to work. It appears to me that the company has not really looked at Mac solutions for many years as their literature refers to Mac OS 10.13 High Sierra (we are seven OS iterations later and into Silicon Mac). This product probably works OK with Intel Macs but definitely not my 2024 M4 iMac.
