Portable SSD not appearing - Help Format?

So, I got an 8TB Portable SSD. When I plug it in, it doesn't appear the way other USB's and SD cards do


I am able to find it when using Disks, but it looks like this

Any attempts to format it result in the same error

This is what appears when I search for it using the terminal:

Any suggestions on things to do would be greatly appreciated. I'm trying to make it so that I can use this for game storage on my PC (doing this on my laptop)

In which format is your external drive formatted?

Hmm ... it looks ike the Drive isn't even formatted - and the Format Process doesn't seem to work. I would suggest to try it with GParted. You can install it with sudo apt install gparted

When installed, open it. You have to type in Your Password; that is normal. When open, choose at the bottom right the Drive and try to format it.

actually he may be able to format it with the disk utility here in Zorin open your menu look for DISKS click it then find the drive you want to format then click here


for the format and partition options you can even set how big the partition is as well the format for linux is EXT4

will look like this

use resize to set the size you want then format to set to format to EXT4

Looks like the OP already tried to format his disk through disks and got the reply about "failing to probe".

Is it possible there is some sort of a lock on the drive? Out of my area of expertise.

And just FWIW here's what Brave says about udisks=error=quark:

udisks-error-quark, 0 is a generic error code in Linux indicating a failure within the udisks2 storage management daemon, often manifesting as "Input/output error," "Device or resource busy," or "Timed out waiting for object." This error typically occurs when attempting to format, mount, or create partitions on storage devices like USB drives or SSDs.

Common causes and solutions include:

  • Device Busy or Mounted : The storage device is currently in use or mounted by the system. Solution : Unmount the device using sudo umount /dev/sdX (replace sdX with the actual device identifier) before attempting operations.
  • Insufficient Permissions : The user lacks the necessary privileges to modify the device. Solution : Run commands with sudo or use a graphical tool that handles authentication.
  • Corrupted Partition Table : Existing partition tables may be corrupted or incompatible. Solution : Wipe the partition table using sudo wipefs -a /dev/sdX or write zeros to the first megabyte with sudo dd if=/dev/zero of=/dev/sdX bs=1M count=1 .
  • SMART Data Issues : The error may stem from udisksd failing to update SMART data on the drive. Solution : This is often a benign log error, but updating the libatasmart package or applying relevant patches may resolve it.

well the next question would be is the drive mounted? i did see that was a fairly large drive. not sure if linux has a size thing like windows

It’s not, and that’s part of the issue

I will try this once I’m home! Thank you so much, hopefully it works

So the options aside from formatting like resizing are greyed out, and as a noob with the terminal I’d tried a few different commands but would receive an input/output error

Btw *Her or Their, not a he lmao

Only to mentioned that: I had a little Mistake what I have corrected:

Sorry, no offense intended! LOL

I was just pointing out that you'd already tried what was being suggested. Maybe Gparted works as @Ponce-De-Leon suggests.

I probably know no more than you but if it doesn't maybe the first suggestion for corrupted partition in the Brave response would be a low risk option. Then see if you can format to ext4 through Gparted.

This would be my first guess - which you suggested earlier.

Sorry to hear of the troubles, in drive formation. This reminds me of the Windows days, when a 200GB drive could no longer be formatted as FAT, and reuqired NTFS. Hopefully, EXT4 can handle whopping 8TB drives. I personally, have only dealt with 1TB and 2TB drives.

Typically, the DISKS utility is perfect for formatting external drives, to EXT4. The other option, would be to use Gparted to handle that task.


Here's what happened:

Error Message: Input/output error during read on /dev/sda

The backup GPT table is corrupt, but the primary appears OK, so that will be used.

Hmm ... did You checked the Cable? And maybe replace it with a different one and try it again.

Do You still have a Windows PC or an You ask someone who has one to use it? If yes: connect the Drive with it and check if You there can format the Drive or if it behaves the same. When it behaves the same, it seems to be an Issue with the Drive.

I think you can just click on ignore. It says the primary table is OK.

Just writing to add that ultimately, I wasn't able to make any solution work so I have decided to return the SSD's and will be getting something different.

If anyone has any recommendations I'd greatly appreciate them! I'd prefer to get something that's high storage so that I can put my games in there and save space. But definitely something compatible.
