I have a transcend 1TB external Drive.

I recently ran into an issue where the drive won't mount on macos or windows. I also tried using SMART tools to scan and the following output is pasted below.

Please can anyone tell me if this disk is recoverable or if i can copy my data out, if so, how can i achieve this.

Thanks in advance

The disk is dying, currently with 1279 bad sectors. Get a new disk at least as large as the old one, then use ddrescue to salvage as much data as it can from the old disk. Then you can see what it takes to fix up the copied disk so that it can be mounted.

Thanks a lot for your response.
I'd plan for this.

Do you happen to know anyway/tool i can recover select data from the drive if its still available? i have a folder of extreme importance i won't want to lose.

testdisk can often recover files from filesystems too damaged to mount. I've never used it for that purpose, so I probably can't be of much help.

Thanks a lot.

I am currently trying to use testdisk to see what i can recover by following the guide on the linked page. Using ddrescue would require some time for me to set it up and understand it fully, i see some python codes and ubuntu/fedora OS. I do not readily have any of those environments set up, would look into setting one up for this purpose

Thanks a lot, you've been of immense help

I wish you the best, (intact files/dirs)but all you're likely to get is clusters which you have to piece together.

The key is to backup important stuff. That's what to take away. There's also a lesson to check the drives regularly. I've been caught out so often I now install a 'save my butt' distro and keep a usb key in case grub goes.

Just download SystemRescueCD and put it on a USB stick. It has testdisk, photorec, and a bunch of other useful utilities all included.

Be careful not to initiate any write actions - except recovering partitions, if you're very sure.

If you need that folder you mentioned to pay a few hundred $$ for it, there's professionals at this sort of thing you can pay.

thanks a lotttt!!! got the folder out and i think the drive gave up right after!!
was able to see my directories and most files too..phew!!

Great! Now buy yourself a usb drive and back things up. There's also places online (I use mega.nz) where you can back up vital stuff. It's wise not to rely on one backup, because that usb drive will fail also. I have a usb caddy with the controller going funny, so I fluttered €60 on ebay for a 500G drive. That's after the 1 TB my son left me went AWOL. But as everything was backed up twice, it's no harm done.
