My pendrive is mounting and unmounting again and again there is data in it i want data

how can i recover my data

Do you use Garuda?

yes dragonized version

Without your inxi -Faz output how do I know you are not a closet Ubuntu user?

Generally Garuda users know that output is required for assistance on our forum.

This is not a data recovery forum, but if you post more information about what is happening perhaps someone can help you.

What is the file system on this drive?

How old is the drive?

What types of files are you wanting to recover?

How long does the drive mount for before it unmounts?

Perhaps you could install some software to help you recover the files such as ddrescue.

filesystem is fat32
its more than 7 year old
it took arount 10 seconds before unmounting
there are jpeg file in pendrive

Have you checked what your journal and dmesg show about your USB?

journalctl -b | grep usb

You also may want to consider a lighter edition (although this shouldn’t be related to the USB problem), since I see your HW is quite old and barely reaching the minimum requirements:

PS: I edited your inxi specs post adding ~~~ before and after the text block for raw formatting. Please consider this in the future

Do you have another computer you could try mounting the drive in?

Have you tested this drive on other USB ports?

Do you have another disk with a live boot on it?

If you do, see if it will mount properly from the live environment?

How long have you had Garuda installed for?

Has this been like this since you installed, or did this just start happening?

Are other flash drives mounting correctly?


Further questions:

  • How often is the drive used? When it's used is it only read from, or are files being written to it too?
    -- Has the drive been in a drawer for 7 years? Or rather, has the drive been dormant for an extended period of time?
  • What USB technology? 2? 3? Likely 2 if you said it's 7 years old.
  • Are you connecting to a usb port that is directly attached to the motherboard, or are you attaching to say a USB hub, etc?
  • Has this drive become intermittently operational only when using Garuda? If you were to plug it into say a Windows OS computer, does it exhibit the same intermittent mount/dismount issues?
    -- Furthermore, if you plug the drive into a Windows computer, does it state something along the lines of the drive needs to be 'repaired' or 'filesystem checked'?

e: dang it, so sorry mods, for some reason old threads will pop up in my 'suggested threads' underneath current posts, apologies for re-bumping an old post.

No worries, nothing wrong with reading old threads but try to make a habit of checking the date before you jump in.

I think sometimes the "suggested" threads discuss topics which appear to be similar or related to whatever you are currently reading. You are right: sometimes the suggestions are old.

I'll close this one down.
