Hi, welcome to the forum ! What PPC Mac do you plan to use a 1TB M2 sata card in ? For OS 9, 1TB is overkill as the OS can only see 128GB of it, but for OS X, no limit - tiger or Leopard will make use of it.
Thank you. I have a few iMac G4, a 700 Mhz, 1 Ghz, and a 20'' 1.25 GHz. Also an eMac 1.25 Ghz and a 1.42 Ghz. Last is a PowerMac G4 MDD DP 1.42. The PMG4 will probably be the first to try, as it is the quickest and easiest to test. The Samsung EVO 860 is a straight 2.5 SATA drive, not an M2 SATA, mSATA, etc. It's also not really intended to be permanent. It was a test buy for a different computer, that I haven't yet tested, since I was trying it out in a 2010 white polycarbonate MacBook and never got around to doing anything else with it. It just happened to be on sale for about $100 at the time, and matched what I was looking for to try on a different computer. I saw no reason to buy the newer form factor/faster drives for a higher price for no speed benefit. I might end up keeping it in the PMG4, since I was planning on using that as possibly a OS9 & X machine maybe. Still not 100%, I might just decide that it will be an OS9 only machine. I'm willing to test on all of those machines, as I haven't gotten to doing a deep clean of them, and one of the eMacs was only bought to fix up the other because the case was damaged during shipment. I probably won't be able to test them all on the same day, since it will take time to disassemble all of them. Would it be as easy as just installing the unsupported hardware OS9.2.2 on the drive, and simply connecting them to all the machines?
Also when I was buying the drive over a year ago?, I read some stuff about the smaller capacity EVO 860 might have some compatibility issues due to a different controller? being sometimes used in them, but not in the higher capacity ones. I do not remember what the cutoff was. Maybe some of the issues with an 860 not working is because of this? We will find out if my 860 works, when my StarTech adaptors get here sometime next week and I can test it out.
