To start off I have 3 disc drives currently connected to my Plex server running a script called ARMI’m having nothing but issues my 5.25" SATA Bluray drive. A portable USB one works just fine and other 5.25" DVD might be dying of old age.
I bought the Bluray drive new in April, it worked for a while, but would rarely intermittently disappear from /dev/ and occasionally cause the entire system to hang. Most of the time when the system came back up it wouldn’t even detect the drive. Running dmesg | grep dvd wouldn’t pull up any log. Searching dmesg | grep sata for information pulls up something like this:
[ 3.612519] ata6: SATA link up 1.5 Gbps (SStatus 113 SControl 300)
[ 3.614748] ata6.00: failed to IDENTIFY (device reports invalid type, err_mask=0x0)
I’ve tried different SATA cables, different power cables, putting it on my 3 different SATA controllers, putting them on different ports on each SATA controller. This happens with every one of them.
My BIOS sees all 3 disc drives so it’s making me think it’s a Linux-related issue.
I saw someone with a similar issue here and they list their workaround as disabling IOMMU in the BIOS, disabling that doesn’t appear to do anything.

I’m still learning my way around Linux, and I’m not really sure where to go next.
