There won't be a problem in vid and pid because it was in auto detect mode. I don't think it is the SATA problem because if it's can't found any disk, there should be a error message shown as " No hdd Detect". Are you using the lastest ARPL 0.4-alpha4 version ? The pat file shoud be "DSM_DS3622xs+_42951.pat". Good luck

Would it be a IDE controller in your mother ?

DiskIdxMap=00 SataPortMap=4 SasIdxMap=1, are u using this config?

this is a good news, thanks for the info 😀

nvme disk only can use as a disk cache

use synology assistant to find out what version are installed in the system

pat file version didn't match with the bootable usb version

First loader in USB, edit the grub.cfg , add those object in red into the line that was already in there linux /zImage HddHotplug=0 withefi console=ttyS0,115200n8 netif_num=2 syno_hdd_detect=0 syno_port_thaw=1 DiskIdxMap=0C00 SataPortMap=42 SasIdxMap=1 vender_format_version=2 mac2=000000000000 earlyprintk mac1=001000000000 syno_hdd_powerup_seq=1 pid=0x5591 log_buf_len=32M syno_hw_version=DS918+ vid=0x0781 earlycon=uart8250,io,0x3f8,115200n8 sn=1780PDN123456 elevator=elevator root=/dev/md0 loglevel=15

We're not there yet, don't use important data which is value to you. Keep your data in where it is, use test data for test only. I am using LSI 9311 for hdd pool, X520 for 10g nic, I haven't found out how to inject those driver yet, still under observation
