My setup is:

Raspberry Pi Model 3B V1.2

No USB HUB

External 3.5 inch HDD:

  • Powered Enclosure: Sabrent USB 2.0/ESATA to 3.5 Inch IDE or SATA/SATA II Aluminum Hard Drive Enclosure Case with Cooling Fan.
  • HDD: HGST Ultrastar 7K4000 HUS724030ALA640 3TB 64MB Cache

I can mount the drive just fine in fstab and read, write/ make subdirectories just fine. The disk will stay mounted for days if I dont mess with it. Writing small files to the disk is just fine too.

The issue comes when I try to write a large file (~1 GB movie). It will go well for the first few hundred MB and then stall and then quit with the following message: "Error splicing file: Read-only file system" What has happened is that the drive is just spontaneously ejected during this process.

Resolution steps attempted:

3 different power supplies

  • 5.25V/2.5A (KANO)
  • 5V/2A (Apple 10W)
  • 5V/2.1A (Generic)

file transfer method

  • GUI drag and drop
  • cp command
  • mv command
  • > command

deprecating USB speed

  • add dwc_otg.speed=1 to /boot/cmdline.txt

increasing USB power

  • add max_usb_current=1 to /boot/config.txt

At this point I'm out of ideas to try, because now I'm at my limit of what root cause could be.

I'm new to linux and RPi. I started this whole endeavor to set up a low-cost low-power home NAS, Time Machine target and PLEX server, so this is kind of a dealbreaker.

This is not a complete answer but a suggestion to narrow down the problem. All transfer methods you have used are using the same buffered input/output API of the operating system so it shouldn't make a difference. To test low level direct writing of random data without using buffered I/O you can use dd assuming disk partition /dev/sda2 is mounted at /mnt/p2/:

rpi ~$ sudo dd if=/dev/urandom of=/mnt/p2/random.file bs=1G count=1 oflags=direct

If this fails then you should look at your disk and its hardware. You should repeat the test with a fresh flashed Raspbian Buster Light image to exclude any side effects of your installation. If this works then you have a problem with the additional software you have installed.

I don't know if it's possible for you but after a backup of the disk you can try to "clean" it up with

rpi ~$ sudo dd if=/dev/zero of=/dev/sda bs=4M conv=fsync

This will overwrite the complete disk with all zeros and may take hours if it doesn't fail. This will also test if low level writing is the problem anywhere on the disk not only where you wrote random.file. Afterwards you have to repartition the disk and create the filesystems.

  • I have replaced the disk and it still happened, so I wwapped the data cable and was able to tsfr a file so I thought it was resolved. When I went to copy more, it still fails. I think its the enclosure, as another enclosure I have works just fine albeit with a different disk... so I suppose it cold be that these HGST disks don't play nice, but I seriously doubt that. Is there such a thing as needing to install the right USB driver under Raspian? How would I even go about finding out what it would be? Commented Mar 1, 2020 at 2:15
