[SOLVED] 128GB NTFS USB drive causes boot to fail

[patricia1066]

The Thinclient HP t520 has 8GB drive, serving for boot and swap.
Music is on the 128GB USB drive.
Hence I really need to get this USB 3.0 to work. 
Every time I booted up with USB I had a fail, it did not even reach post until I removed the USB drive.
T520 screen :  Invalid Partition Table

SnakeoilOS loads the drive when I plug it in, and LMS can load sdb1 into the /media/music folder. I can then play music from the USB.

What I have done to try to make music happen-

I formatted USB in Windows 10 disk manager, created a partition, made it active, NTFS. 

I followed the walk through on this site to mount it to fstab.

# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
# / was on /dev/sda1 during installation
UUID=205e2f3e-1ead-4b1f-a0bf-469a0b1ae3fd /               ext4    errors=remount-ro 0       1
# swap was on /dev/sda5 during installation
UUID=922a946d-c6f7-4c31-81a0-e765f84ed2b4 none            swap    sw              0       0

UUID=40BC1DE9BC1DD9EC /media/music/sdb  ntfs defaults 0 0


I closed down LMS, rebooted snakeoil via webserver. 

This time, there was a difference - No POST but the screen I hooked up to t520 said:
There is no drive with an operating system. Please remove all drives without an operating system 
Press Ctl-Alt-Del

When I followed this it loaded Ubuntu and waited at the point where 40BC1DE9BC1DD9EC  was being looked for - I had time to insert it and the OS continued to load. This isn't a viable procedure as I turn off the t520 every night. 

The drive appears to work in Windows, and in NTFS it works in Snakeoil until reboot. 

Any ideas on what to try next?

Should the mount point be sdb1?

Edit - I just checked the USB drive is corrupted since I shut down so no good. Probably occurred when the system was seeking it

Edit 2 - I reformatted the USB drive - and when I rebooted snakeoil failed to complete boot even when I reinserted the USB. 
It had been given a new UUID on reformat. I had to reinstall Snakeoil.

patricia@t520:~$ lsblk -o name,mountpoint,label,size,uuid,fstype

I am using another usb drive now, and getting interference, crackling and noise so loud I have to quickly turn off my audio to protect my ears and speakers.
On the Snakeoil tab it says SYSTEM.USER_NOT_FOUND
I am at a loss , no one else has these problems?
