This seems to be the key. I downloaded the 141126_A1_EE_82 firmware (from 'here' (https://www.station-drivers.com/index.php?option=com_remository&Itemid=353&func=startdown&id=4053&lang=en)), and the zip file includes a Windows executable to flash the firmware. The executable also tells you what version is already on the device. It told me that the old SATA adapter (which supports trim with my Sandisk SATA SSD) is (was*) at firmware 141126_A1_EE_83, whereas my new Argon 40 M.2 SSD adapter was as 140704_A1_00_00. If the lower number corresponds to an earlier version, it seemed possible that an update to a higher number might enable trim. So I took a brave pill and decided that if I bricked the adapter then I'm only out £18. I updated the M.2 adapter to 141126_A1_EE_82. (Note that the update will FAIL if there's a disk drive attached - this is what I tried first, because detaching the drive requires a small amount of disassembly, and I was being lazy). Now when I inspect the adapter+drive as before under pCP I see: Code: -------------------- tc@pCPServer:/mnt/sdb2/tce$ sg_vpd -p lbpv /dev/sda | grep Unmap Unmap command supported (LBPU): 1 and tc@pCPServer:/mnt/sdb2/tce$ sg_vpd -p bl /dev/sda | grep unmap Maximum unmap LBA count: 4194240 Maximum unmap block descriptor count: 1 Optimal unmap granularity: 1 blocks -------------------- So now it looks as though the adapter supports trim and I can press on and enable it. It's odd that the Argon M.2 adapter, which I purchased ~18 months after the old SATA adapter, should have an apparently older firmware. I hope the update hasn't broken anything else, because I can't find the 140704_A1_00_00 version to revert it. *I 'accidentally' loaded the 82 firmware over the 83 version that was already on my old SATA adapter, so now of course I'm worried what feature was added/fixed in that single digit increment! ------------------------------------------------------------------------ chill's Profile: http://forums.slimdevices.com/member.php?userid=10839 View this thread: http://forums.slimdevices.com/showthread.php?t=113575
