Ubuntu

Bionic has problem with multiple external drives.

Asked by Robert Pearson

Ubuntu MATE 17.10 and 18.04 work fine with up to 4 external USB drives. They are all NTFS since hfsplus is problematic on both versions. When I add a 5th in 18.04 it shows up in Caja but is unmounted. When I try to mount it nothing happens. When I chose "safely remove the drive" all of the external drives disappear. Disks can't see them. I have to re-boot (after disconnecting the 5th drive) to get access to the other four. I tried with 3 different drives, so I do not think that is the issue. When I try 6 drives they all go away. ???

I have programs which I use the make changes in all connected volumes at once. If I cannot connect all the drives at once, I have to make the changes over and over for every set of 4 drives.

The processor is an AMD 64-bit processor. I connect some drives directly and the rest through a USB3 powered hub. The 5th and 6th are through the hub.

If you use command line and use the eject command to get the drive removable, is it OK there? Just to test

Have not tried command line, only Caja and Smalltalk VisualWorks. I do not understand your question. The problem is not ejecting the drive. It is that a fifth drive is not mountable and a sixth renders all external drives non-existent.

Sorry for not responding earlier. I tried EasyRE to get windows 10 working. Instead, it crashed trashing Linux system (all external drives are mounted read-only. All internal unlocked partitions are mounted as read-only. This included drives that were not even connected to my system when EasyRE crashed.) Two weeks with no contact from "tech-support". There must be only one guy and he is on vacation. Support is just as bad as Microsoft.

In my opinion the first step of diagnostics has to be to find out whether mounting the fifth (and sixth,...) drive really fails, or if this is just a problem of the caja file manager not being able to correctly displaying them.

Try mounting four drives and issue the command
mount
Then insert a fifth USB stick and repeat the command
mount
Are the previous sticks still shown as mounted? Is the new one mounted?
What is the output of the command
dmesg | tail
What is the output of these commands after adding a sixth USB stick?

(Correction: Please replace the word "USB stick" by "USB drive" in my previous message.)

Manfred, I already did in my head.

Here are the results of the mount command -

"Unable to mount 3TB MyBook 1

Error mounting /dev/sdh2 at /media/robert/3TB MyBook 11: wrong fs type, bad option, bad superblock on /dev/sdhw, missing codepage
or helper program, or other error."

This is an NTFS volume which worked fine until I shutdown Windows 10 and started Ubuntu MATE 18.04.

The 5 TiB volume does not show up at all.

It does not have a high priority since the "easeRE" virus has rendered all my external drives and all unlocked internal partitions as read-only. (Even the ones not connected to the system when the virus ran and crashed.) Does anyone know how to undo the damage done to my system by "EasyRE". NeoSmart has not responded to my requests for technical support. Apparently they have none. (But they do have an impressive web page. Unfortunately their product does not work.) It is supposed to be an UEFI application so I need an UEFI expert.

You have to be aware that NTFS is a proprietary file system from Microsoft. Linux does the best what it can do with it, but usually prefers not to modify such partition (hence default is mounting it read-only).
Furthermore the fast-boot (aka. hybrid sleep) feature of the newest Windows OS versions leads to the case that even after a shutdown of the Windows OS the NTFS partitions used by the system are not cleanly unmounted. Ubuntu refuses to mount such partition with a message like "missing codepage or helper program, or other error."

I do not understand what you are writing about EasyRE. This is not a virus, but a recovery tool for Windows.

Some suggestions:
Connect one of the drives to a Windows system, do a chkdsk on it and perform a "save remove". Then try connecting it to your Ubuntu system. I assume that it will still be mounted as read-only. What happens if you try remounting it read-write (sudo mount -o remount,rw /dev/xxxx)

Manfred.

Not true. Ubuntu MATE comes "out of the box" able to both read and write NTFS since so much of the computer world. Also Linux must be able to read and write FAT32 file systems in order to use the smaller jump drives (USB "sticks").

I have Fast Boot turned off. I also have Secure boot turned off since it prevents Windows 10 from booting on my system.

Thirdly, I had no trouble reading and writing NTFS previous to running the "EasyRE" virus.

EasyRE is advertised as a recovery tool. But it crashed when I tried to run it. And It wrecked my system. NeoSmart has refused to provide any support for over three weeks. That makes it a virus, not a recovery tool. If they had made the slightest effort to help, it would be a different story. As it stands, I say it is a virus. (Maybe one of the first UEFI application virus.)

Did run the chkdsk and safe remove. No change in the situation. It still mounts as read-only. (Your assumption is wrong>)

I do appreciate that you are trying to help (unlike actionparsnip). Please keep trying. And I recommend if you actually try EasyRE, do it on a system that it is okay to trash. Nothing vital on it.

If you have problems with a Windows program like EasyRE, then this is the wrong address. This is support for Ubuntu only.

Have you tried remounting (one of) the drives read-write?

Robert Pearson (rpearsonii) said : 		#10

Manfred,
The problem is not with windows. After running EasyRE Linux mounts all my drives as read-only. The only writable partitions and the UEFI System Partition, the Ubuntu MATE 18.02 partition and the Linux swap partition. I cannot use any of the Ubuntu tools since the drives are mounted read-only.

I had just gotten Ubuntu so that I could work, then it got trashed. (NOT Ubuntu's fault!)

I am trying to salvage my data. Could you provide a link on how to create a live, persistent USB "stick" so that I can install it on an external drive and the use the Linux tools to recover my data before wiping the internal drive and reinstalling Ubuntu. I use a hard drive with a GUID Partition table and boot with UEFI.

How do I "tried remounting (one of) the drives read-write"? (Please remember I am a Linux newbie.)

Manfred Hampl (m-hampl) said : 		#11

I have already given the command for remounting a drive read-write in a previous message:
sudo mount -o remount,rw /dev/xxxx
(replace xxxx by the name of a partition)

Can you help with this problem?
