hfs harddrive corrupted get data

[tiblop]

While I was transfering pictures on my external hardrive (HFS+, 1To), it got accidentaly disconnected. When I plugged it back in, my mac recognised it, show me all the folders but they were all empty. I wanted to eject it to replug it in but it didnt work, I couldn't eject it. so I unplugged it without ejecting it. then replugged it, now its not recognised by my mac anymore. It appears in diskutility but it cant mount. I tried the first aid , on the main partition (disk2) it says no problem, on the subpartition (disk2S2) it can't do it. Error message gives exit-code 8

I ran photorec on it for over 2 days, and it gives me error reading sector for 100% of my sectors , 0/10 header found, estimated time of completion over 2 months... So I ended up closing it...

I tried to run testdisk but it just says "please wait" at begining and that's it... I tried to copy the whole disk into another disk using dd command but it keep telling me "ressource busy" (the corrupted one) when i unmounted both drives ...

I don't know how to get SMART infos from my harddrive, i tried smartmoontools but it gives me:

Operation not supported by device

I have a similar harddrive so i tried to copy the partition hierarchy using pdisk ( following this : https://perrohunter.com/repair-a-mac-os-x-hfs-partition-table/) but it gives me :


pdisk: Unable to write block zero (Input/output error)
pdisk: Unable to write block 1 (Input/output error)
pdisk: Unable to write block 2 (Input/output error)
pdisk: Unable to write block 3 (Input/output error)
pdisk: Unable to write block 4 (Input/output error)
The partition table has been altered!

What else can I do do get my data back?

Thank you for your help

With what you already tried, your next step would be to send the disk to a data recovery shop to be looked at.

I agree - - professional data recovery.

There's nothing you can do with it (except may be make the chances of recovery even harder if you continue trying).
