"Hello,
I created a bootable key to install the latest Linux Mint, and by mistake (in haste), I created the "bootable key" on the 1.5TB HD where I kept my backups. As a result, I lost all my data.
I ran TestDisk, but it couldn't find any partitions initially. Then, while trying to go back (pressing 'q'), it started a 'cylinder analysis'.
The result of this analysis is as follows:
TestDisk 7.1, Data Recovery Utility, July 2019
Christophe GRENIER grenier@cgsecurity.org
https://www.cgsecurity.org
Disk /dev/sda - 1500 GB / 1397 GiB - CHS 182397 255 63
The harddisk (1500 GB / 1397 GiB) seems too small! (< 3000 GB / 2794 GiB)
Check the harddisk size: HD jumper settings, BIOS detection...
The following partition can't be recovered:
Partition Start End Size in sectors
It's better to see it in an image:
Does anyone have an idea of what this means?
Could creating a 'bootable key' on my HD interfere with TestDisk's analysis of the disk?
Would it be better for me to remove the Linux installation files from the disk to have a greater chance of data recovery?
Or any other suggestions, of course.
Thank you for your responses.

There is a small partition at the end of the disk.vince99 wrote: ↑27 Jul 2023, 11:43 "Hello,

You should not create another one before having finished all your recovery efforts.
Could creating a 'bootable key' on my HD interfere with TestDisk's analysis of the disk?
Do not alter the crime scene unless being in certain corner cases where Testdisk is awakening the death.
Would it be better for me to remove the Linux installation files from the disk to have a greater chance of data recovery?
Re: External hard drive mistakenly formatted while creating a bootable key
Thank you recuperation.
I must have made a poor translation.
While searching on this forum, I found Jamsah's case and I was wondering if I could try this solution?
Is it dangerous for the data? Should I create an image of the disk first?"
Thank you.
