Try posting those details here, you might get lucky and someone may help you. I know I just picked up my second areca last year, and it's been great with my old 4 tb drives as my new 8tb drives. The newness of your drives is likely the issue, but we need more information.Regarding Areca and TLER/ERC/CCTL .... well guys ... Since going with 12TB drives I just have endless problems - i.E. not working in the end.
I have multiple Arecas 1260, 1880 and 1882ix-24 (4 GB) .... The 1882 was even on a compatibility list from my HGST Ultrastar/Enterprise 12TBs .... but no TLER/ERC/TTL - Newest Firmware on Areca, Newest BIOS, Newest OS.
And on other drives (12TB Ironwolf (non Pro) ... TLER/ERC/CCTL works on 1260, but NOT1880 ... but 1882 works again ....
Areca support is somewhat unhelpful and just says basically.... well it recognizes the disk ....then it's fine ... I did explain the problem carefully. But Kevin doesn't seem to bother.
I did stress test them with HGST 12TB + Areca 1260 (with no TLER/ERC/CCTL) it did not take long and some HDs just dropped randomly out (no surprise).... The drives are brand new HGSTs and are okay..... I investes so much time in this BS and even the "both is on a compatibility list"helps nothing. Like proofed here. When you read the fine print they anyway don't do stress tests with most models - Then you also can drop the whole compatibility BS, since I never had a single SATA disk which was not recognized by any controller. And I have a few hunderd disks here.
Probably time to drop that Areca shit and move to ZFS.
I was very happy with Areca before with smaller/older disks, which I used heavily for years and did basically all you can do withit ... But it just doesn't work anymore.
