sbv3000 Posted September 2, 2022 Share #2 Posted September 2, 2022 What is your mobo hardware setup? -Its good to include that in any posts to help members help you diagnose problems Meantime, Maybe the sata ports 3/4 are disabled in bios? Not set to AHCI ? HDD power not connected properly? Faulty HDD Can you see all the disks in the BIOS? Quote Link to comment Share on other sites More sharing options...

sbv3000 Posted September 3, 2022 Share #4 Posted September 3, 2022 spec says 4 sata ports so should work, but check the settings in bios as before also in the tcrp loader terminal, run the satamap option to find your controllers and drives (but dont update user_config.json) report back results you might try a 'non-device tree' build, DS3615/17/22, could be the 1621 devicetree isnt working right. As an aside, I'd disable any onboard peripherals like audio, serial, parallel, not needed and they take system resources. Quote Link to comment Share on other sites More sharing options...

sbv3000 Posted September 3, 2022 Share #6 Posted September 3, 2022 the system spec says 4 sata ports but the satamap shows 6 with two bad not mapped. How many physical sata ports on the board? might be that your third drive is connected to one of the ports that is considered 'bad' and so devicetree is ignoring it. Try the other sata port(s). You might try a build with 3615/17/22 image and 'manually' overwrite the satamap to '4'. I would disconnect your two SSD and create a new loader with one of these images and see if you can install on the HDD on the port its connected to. If that works you know its a devicetree issue. In theory you could reconnect your SSDs, boot with the 36xx loader and migrate from 1621 to 36xx, but I would backup data from the SSDs before trying that.
