rerror

I get a similar error if I have a CH340 USB to Serial device plugged in, specifically this LCUS-1 USB Relay Module. The only way I can get DiskSpeed to run is with the device physically disconnected. Error log

I'm now on 7.3.1 but whatever the current/latest version was on the dates I posted.

That did occur to me and I was planning on borrowing different cables from a friend, but I finally figured out the issue. I found the solution here. The card was originally from Dell and they have some sort of flag/parameter(s) set that aren't overwritten with a firmware upgrade. The card won't detect drives without completely erasing the flash (sas3flash.efi -o -e 7) before writing new firmware. I wasn't sure if it mattered but just in case I took a backup of everything (bios, firmware, firmware backup, flash, nvdata) and made note of my SAS Address before erasing. I had to manually reprogram the SAS Address but I don't think it would've mattered. My drives now show up in the LSI BIOS and in UNRAID. EDIT: Comparing the backup dumps from before completely erasing the flash, the firmware is definitely modified/different when being upgraded (written overtop of existing firmware). I could only get a perfect checksum with the firmware file originally provided after a fresh install (erase, rewrite) and redumping.

I'm an UNRAID and SAS/HBA noob so apologies if this is an dumb oversight on my part. The system is a budget-build using parts from one of my old gaming rigs (Asus Maximus IV Gene-Z, 3770k, 32GB) and most of the drives I had kicking around. I purchased a used 9305-16e to hookup the UNRAID box to a JBOD using these SFF 8644 to 4x SATA cables. Once received I updated the firmware and BIOS to the latest versions (had to do it inside Windows using Hiren's BootCD PE, this motherboard refuses to run sas3flash.efi and I can't flash inside DOS because the motherboard is missing the BIOS32 service) using the following package/files; 9305_16e_Pkg_P16.12_IT_FW_BIOS_for_MSDOS_Windows \Firmware\SAS9305_16e_IT_P\SAS9305_16e_IT_P.bin \sasbios_rel\mptsas3.rom The JBOD drives are powered by their own ATX supply which can be turned on/off remotely. The only things connecting the two boxes are the SFF 8644 to SATA cables and earth/chassis ground. The HBA is installed in the top 16xPCIe slot and an ASM1166 6x SATA expansion card in the bottom slot (preferably I'd like these reversed but it causes the LSI BIOS to not work - it snows up at POST and acknowledges the CTRL+C command, but then just continues booting the PC BIOS). I can get into the HBA's BIOS but it will not detect any drives. UNRAID detects the controller (Serial Attached SCSI controller: Broadcom / LSI SAS3216 PCI-Express Fusion-MPT SAS-3 (rev 01)) so at first I was thinking I received bad cables or the ports were disabled. I tried using lsiutil to enable them but most any command gives me a "0 MPT Ports Found" error. I spent a couple hours trying various things to no avail and have started going stupid so I must ask for help (different 8644 cables (although from same batch), different PCI slots, with/without other hardware combinations installed, different hard drives, drive powered by internal PSU, drive powered through molex adapter to eliminate 3.3v). Basically the only things I haven't tried are installing the card in my modern AM5 system to see if anything is different, trying the other firmware with ACM (even though these 8644 cables are not active), or something I'm not thinking/aware of (most probable). What am I doing wrong/what should I try? Thank you. EDIT: Solved! Solution here
