Public bug reported:
Receive this error in the error log when reading from the drive -
kernel: [18057.860057] usb 1-3: reset high-speed USB device number 18 using
ehci_hcd
I have tried deleted all the partitions. Created a 350GB EXT4 partition.
Copied a 700MB file to it no problems. Tried copying the file back off
the drive to the laptops drive and the problem re occurs. Therefore,
this bug is when it reads from the drive rather than writes to the
drive. It also appears I need to do the following in order for the drive
to stay mounted -
sudo echo 5 > /sys/module/usb_storage/parameters/delay_use
What is interesting is if I leave the drive on after it has this error
and disappears off the USB Bus, I can hear the drive....sounds like the
heads are contractually trying to read the disk.
Turn the drive off and on again, the drive mounts without problems -

filesystem with ordered data mode. Opts: (null)
Dec 23 14:05:23 coralreef udisksd[1731]: Mounted /dev/sdb1 at
/media/clownfish/EarthData on behalf of uid 1000.
Can write to the drive without problems.
As soon as I read from the drive and either copy to the same partition or
another partition on another drive, the system log reports -
