Smartmon with UAS

There’s a known issue in linux where USB disk won’t run smartmon with UAS because of the driver This is how to disable th

How do I know if I’m using UAS driver

if you use lsusb -t the output of this command will give you the information You can see below the second line contains Driver=uas

#lsusb -t
/:  Bus 03.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/4p, 5000M
    |__ Port 3: Dev 2, If 0, Class=Mass Storage, Driver=uas, 5000M

Find the idVendor and idProduct fields for your device

Since we want to disable it via quirks, you need to find your idVendor and IdProduct

Again lsusb without option does the job for me

I know that drive is the only Seagate on my system, so I don’t have problems locating it. The idVendor and idProduct come after the work ID (3rd line)

#lsusb
Bus 002 Device 002: ID 8087:8000 Intel Corp.
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 002: ID 0bc2:3322 Seagate RSS LLC SRD0NF2 [Expansion Desktop Drive]
Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 002: ID 8087:07dc Intel Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Update initramfs options and reboot

Add the quirk option to your configuration We’ll be telling the kernel to not bind UAS for this drive

usb-storage.quirks, u = IGNORE_UAS (don’t bind to the uas driver);

echo "options usb-storage quirks=0bc2:3322:u" >> /etc/modprobe.d/usb-storage-quirks.conf
update-initramfs -u
reboot
