16gb usb shows only 8mb space after using ventoy. - aniruddha1947 - 12-14-2022

Hi,

I am a noobi linux user. I started using ventoy to try different distros of linux.
I successfully used ventoy with my usb drives except one usb drive.
After install installing ventoy and putting iso on usb drive, usb shows only 8 mb space out of 16gb.
I am not able to access the other partiton as it is not visible.

Could anyone explain what could have happened and how to resolve the issue?

I did diskpart and assigned letter. Then it was showing unknown capacity so performed following

select disk
clean
create partition primary
active

now it is still showing only 8 mb space.

Upload log.txt here for analyze after install Ventoy.

ventoy drive is sde as there was another pendrive attached while performing above commands

The system indeed recognize your USB with 8MB space, I don't know why.

I tried many tools to explore this usb using windos os and linux, but no luck.

Is there anything else I can do?

Hi again,

I had given up the hope to solve the issue so I decided to f*ck around to know more.

I started exploring articles about how to recover data. I came across the below article.

https://www.digitalocean.com/community/tutorials/top-best-linux-data-recovery-tools

I started using tools mentioned in the article.

As mentioned in earlier posts, it was clear that there was problem with partition table and usb was not corrupted as cat command reveled that block size was 16384 (I think it means 16*1024mb=16384MB=16GB).

So I used ddrescue and changed the structure using other articles but it did not solved the problem.

Then I came across below article

https://www.easytutorial.com/flash-usb-drive.html

I followed it and it solved my problem. It did not recover the data but It allowed me to use the flash drive again.

I am no technical expert so I could not understand information reveled using ddrescue tool and could not recover the data but I am sure experts can. I think in problems of corrupted usb, ssd and hdd devices, ddrescue tool can definately give some insight to define the issue, which can allow to lay the strategy to troubleshoot the issue.

I hope this information can help to solve such problems in future.

Thanks to all of you again.[img]data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7[/img] Smile
