Permissions error mounting USB drive

[ian_r_h]

Hi, all,

Sorry for the embarrassing opening statement as I have worked in IT support for many years...

...but I failed to note the exact error at the time it occurred...

I know.  I know.

Mounting a Kingston DataTraveller G4 16Gb USB stick it appeared to mount, but on attempting to copy a .tar.gz archive from my HD reported a permissions error.  The drive had worked yesterday in initial testing.

I had had this problem before when trying out Ubuntu-Unity, but thought it might either be a bug in that distro's file handler (Nautilus?) or else something happening after I tried using a different USB stick first (which also didn't work properly).

The Kingston USB drive was sold as compatible with Linux by my local computer store, who also couldn't resolve the problem.

The syslog file reports the following (the subsequent corruption was possibly due to me physically removing the drive after cancelling the copy attempt in Thunar, at which point it disappeared from the list of attached drives).  Syslog below my sign-off.

Any help will be greatly appreciated as this is (again) blocking my ability to backup data.

Thanks,
Ian

Two updates:-

1.  The USB stick permissions from right-clicking the desktop icon that appears read (now anyway):-

Owner: root (root)
Access: Read & Write
Group: root
Access: None
Others: None

Which is why I'm guessing gparted run from the menu is not offering any formatting options.

Unfortunately, I don't know how to sudo run gparted from the terminal; or being new to linux still how to even change the permissions in the terminal back to me.

2.  I can burn to DVD on the laptop, so I am at least able to backup that way for now (and they verified from SHA-256 after burn).  If that finalized the DVD then that downgrades the urgency of this for me for now.

[ian_r_h]

I hope no-one minds me adding my own "replies", but I figure this will be helpful for someone else down the line...

So I have managed to change the permission back to myself (thanks to another thread here) in the terminal:-

sudo chown -R ian: /media/ian/E07F-B980/

But I still don't know how to format it to FAT32 again in gparted, as the option is still greyed out.

Have you tried Menu, Settings, Disks? The Help Manual has a section on formatting disks too.

[ian_r_h]

Have you tried Menu, Settings, Disks? The Help Manual has a section on formatting disks too.

Thanks, Jerry.

I'll give that a go in a moment.  Below my sign-off is the output of a second attempt.

In brief:
Formatted USB stick (slow version) in Windows 10 to default FAT32 (8kb block) format.
Rebooted LL laptop.
Connected to LL laptop.
Checked permissions.
Managed to copy two small files, but large file gets part-way and errors: ""Error splicing file.  Input/output error.  Do you want to skip it?""
USB stick vanishes from Thunar view and desktop.
Disconnected and reconnected USB stick.
Checked permissions - which were unchanged (below).
Deleted 0 byte version of long file present on USB stick.
Retried copy and paste, with same error part-way.

Log for first attempt from connecting USB to it disappearing detailed below after signature.

USB stick disappears from file manager (Thunar) view and desktop.

[ian_r_h]

Also:-

Menu/Settings/Disk
Connected USB stick
Clicked tools icon and selected benchmark disk.
Benchmark errored, but error message disappeared before I could note it down!  (Was different to the earlier error message.)
Cannot retry as disk and benchmark windows no longer responding.

Will try rebooting laptop at this point.

[ian_r_h]

OK, error message was just hidden behind the benchmarking window, which closed OK once I cancelled the error message.

Menu/Settings/Disk benchmarking failed after very short time with error:

Error writing 10485760 bytes at offset 309428224: Input/output error (g-io-error-quark, 0)

[ian_r_h]

OK.

Again connected USB stick.
Loaded Menu/Settings/Disks.
Selected to quick format using default settings.
USB disappeared from Thunar view and desktop, so waited a minute and manually disconnected and reconnected USB stick.
Checked permissions, which right-clicking desktop icon showed as same as when formatted in Win 10.
The two small files copied.
But when copying the large file, it gets part way and now errors "Failed to open directory 'KINGSTON'.  Error opening directory '/media/ian/KINGSTON': Permission denied." [KINGSTON was the label I applied this time when formatting as above.]
Drive again disappears (dismounted?)
Manually disconnected and reconnected.
Checked permissions by right-clicking desktop icon, which are unchanged:

Owner: ian (ian)
Access: Read & Write
Group: ian
Access: Read only
Others: Read only.

This last error round is familiar from when it was failing in Ubuntu/Unity, where the file manager was reported permission errors; but these may not be identical in this case.

[ian_r_h]

OK.

Booted up 7 year-old entirely different manufacturer/model laptop with essentially the same build of LL, which is my test unit.

Copied data from DVD backup made to this unit (also verifying the SHA256 hashes).

Connected the USB stick.
Again, formatted it using the default options in Menu/Settings/Disks.

This time, the USB stick did not disappear from the Thunar view and desktop.

However, permissions were set to root, so changed in terminal by:

sudo chown -R ian: /media/ian/KINGSTON/

Verified that the permissions appeared identical from right-click on desktop USB icon, which they were.

Copied files from this HD to USB stick without error (this time - we'll see if this continues; before I have had the USB sticks work for a bit and then not, but haven't tested on this laptop before).

Verified that the SHA256 hashes were correct.

So (touch wood), I have a work-around for myself and - should this recur - for anyone else with a second PC/laptop of different spec... subject to this bug not recurring on the test laptop also.  If it does, I'll update in this post.

Meanwhile, though, I'm no closer to understanding what is going on on my main LL laptop.

[trinidad]

Think Linux: simplicity.

1) What are you copying?
2) What Linux software are you using (not the OS) to accomplish the copying?
3) What do you want the data copied to the USB to do or be?

Be specific about these three questions and we can advise you further. Block offset errors suggest the wrong disk format for what you are trying to do. Probably should have run fsck manually after the unplug as well. Other than that I cannot advise you without knowing the answer to the three questions above.
