After upgrading my OS, I noticed that I lost write permissions on the external SSD drive I use to back up my data with. I attempted to delete and re-partition the SSD using Expert Partitioner. Now the SSD will not mount. Here is the error message:
An error occurred while accessing ‘Home’, the system responded: The requested operation has failed: Error mounting /dev/sdb1 at /run/media/root/27877fed-ea88-476d-8e5d-567c91fb589f: Command-line `mount -t “ext4” -o “uhelper=udisks2,nodev,nosuid” “/dev/sdb1” “/run/media/root/27877fed-ea88-476d-8e5d-567c91fb589f”’ exited with non-zero exit status 32: mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so.
I have successfully repartitioned my device many times, but its possible I caused the error this time. I believe I attempted to do the procedure while it was still mounted. Also I attempted to repartition at the most primary mount point: /dev/sdb, instead of at the /dev/sdb1 selection.
I don’t need to recover any data on the drive, but I would love to bring it back to life if possible.
Try to mount manually. Here is what to do for that.
Work as root.
Manually create a mountpoint (directory), for example /tm
Mount:
mount -t ext4 -v /dev/sdb1 /tm
or try a few variations:
mount -t auto -v /dev/sdb2 /tm
mount -t ext4 /dev/sdb1 /tm
If this does not work, try to find out what is the filesystem on the partition, and whether the disk has a partition and partition table. This can be done in gparted, Yast, fdisk, and perhaps by other means.
If all this does not work, check the disk with smartctl and badblocks. badblocks has a read-only check, but, since you do not need to save data, better run the destructive write check. The smartctl command is safe, but badblocks is not - if given wrong device (disk or partition), it will erase the conent. Here are the commands.
smartctl -a /dev/sdb
badblocks -wvs -t 5001 /dev/sdb
Tell us the outcomes. We will continue from there.
If the above doesn’t work go to the ssd’s whatever brand website and get the tools to do a format thats specific to that ssd and then start over with a fresh like new ssd.
I have had to do that with a samsung and a ocz after messing it up.
Attempts to mount using various commands all result in “mount point /tm does not exist”.
I moved on to the smartctl command, here is the output:
"# smartctl -a /dev/sdb
smartctl 6.2 2013-11-07 r3856 [x86_64-linux-4.1.15-8-default] (SUSE RPM)
Copyright (C) 2002-13, Bruce Allen, Christian Franke, www.smartmontools.org
/dev/sdb: Unknown USB bridge [0x059b:0x0071 (0x006)]
Please specify device type with the -d option.
Use smartctl -h to get a usage summary"
I wasn’t entirely confident on how to proceed with smartctl, so I moved on to the badblocks. Here is the output:
“# badblocks -wvs -t 5001 /dev/sdb
Checking for bad blocks in read-write mode
From block 0 to 124318039
Testing with pattern 0x1389: done
Reading and comparing: done
Pass completed, 0 bad blocks found. (0/0/0 errors)”
Great idea. But it looks like brand support is not existing for me. I have an Iomega 118 GB SSD Flash. When I go to their website, it looks like it is abandoned. It just redirects me to search engine results for various keywords. Hopefully there are other tools that allow me to reformat the device.
Well it is mkdir and you can get full instruction with man mkdir
But you can make a directory from the GUI as well. But details may be a little different depending on desktop but in general you go to the place you want to create the directory in the file browser you use then right click and select create new folder
You do understand that folder and directory are just names given to a named node in the file system and are not really folders or directories just convenient ways for us meat bags tot think about things
I still need a little more “hand-holding” to make a directory and mount to it. I have KDE and use dolphin mostly. I just right clicked along the left panel of dolphin and was given the option to “Add Entry”. When I create an entry named “ssd” it appears in the “Places” section and the contents are identical to the “Home” directory. Is this correct? If so, what is the command line to mount it?
No it is not that hard. Navigate in the browser to root (/) or where ever you want the SSD partition to be
right click in a bank space on the browser window not on any side windows the main brows window where you see files. (BTW this is just like Windows) this will pop a menu in the menu Create New then select folder
Then follow instruction above about mounting the device
Using Gparted I created a new partition table and added a single partition using the recipe above. I received a flurry of error messages when opening the program and with each operation. About 7 errors windows popped up with each operation. Here is one of the common outputs: “Error fsyncing/closing /dev/sdb: Remote I/O error”. I had the choice to ignore or retry, and I clicked ignore to continue the partitioning and it completed the operation.
At first it looked like I was successful, as dolphin now showed a mounted SSD in which there is now a “lost and found” folder. However there are two problems still.
I cannot save in the folder, getting an error message “you do not have write permissions”
After safely ejecting, I get an error message when attempted to mount it again. The same error message posted on the first page.
An error occurred while accessing ‘Home’, the system responded: The requested operation has failed: Error mounting /dev/sdb1 at /run/media/root/65129775-d3c8-4815-9822-b91d6f924c64: Command-line `mount -t “ext4” -o “uhelper=udisks2,nodev,nosuid” “/dev/sdb1” “/run/media/root/65129775-d3c8-4815-9822-b91d6f924c64”’ exited with non-zero exit status 32: mount: wrong fs type, bad option, bad superblock on /dev/sdb1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so.
To be thorough, I also formatted the partition using Expert Partitioner. The same problem exists though. The flash mounts once and shows the “lost and found” folder. The SSD is still unusable with the message “Access denied, cannot write to” when attempting to save files there. If I safely eject, and then re-insert the mounting fails with the error message as mentioned in my previous post.
“In some cases useful info is found in syslog - try
dmesg | tail or so.”
I cannot locate a file or folder named “syslog”. If this is a potential source of solutions, can anyone help me navigate to the syslog so I can share whatever info is there?
Today on systemd (the current Linux subsytem for openSUSE) the comparable command would be the following with “some_number” the number of entries last entered (equivalent of tail). I’d recommend 50 lines, if that doesn’t display relevant entries, you can try a larger number like 100.
Skimming the posts in this thread (hope I’m not missing something),
Did you reformat this Iomega drive?
If not, then you <must> know what kind of fs is on the disk. There are various tools that can be used to detect the fs, one is gparted. The “partitioner” in YAST can probably do this, too.
If you did reformat the drive, then you have to know what you did…
Did you do a complete wipe or simply over-write?
Did you create new partition(s) or simply use existing?
Did you actually format, or is the partition(s) unformatted free space?
Again, if you’re not sure what you actually did, running gparted or the partitioner in YAST should detect what you have.
Another way <might> be to run the following in a console. If you’re not sure what the results mean, post the result so we can take a look at it.
df -h
Only <after> the above has been completed (Fully formatted, verified), <then> you can try mounting.
