[SOLVED] USB Drive issue

[Tim Curtis]

Library DB regeneration after the Sabrent firmware update did hang up without generating the I/O error in the log. After doing some research I didn't realize how VERY picky these RPi 4B's are with regard to USB 3.0 storage adapters.

This is my model Sabrent enclosure: https://www.amazon.com/Sabrent-Tool-free...=UTF8&th=1

In order for some of the more problematic adapters to work you must disable UASP.

Here is what I have done to fix this particular Sabrent USB enclosure.

Identify USB device ID:
sudo lsusb

Bus 002 Device 002: ID 152d:1561 JMicron Technology Corp. / JMicron USA Technology Corp. JMS561U two ports SATA 6Gb/s bridge

Edit /boot/cmdline.txt:
sudo nano /boot/cmdline.txt

Add USB device ID to the beginning of the line:
usb-storage.quirks=152d:1561:u

Write out file and reboot

Here are some very helpful links I found with a ton of info regarding RPi and compatible USB storage devices:

After performing this fix the Library DB regeneration went through no problem in less than two minutes with 8k files.

Nice, and good info. I had no idea there were usb storage quirks.
