From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Repairing bad sectors in an external drive (discuss.tchncs.de)

So I have this external 2.5" drive salvaged from an old laptop of mine. I was trying to use it to backup/store data but the transfer to the drive fails repeatedly at the ~290GB mark leading me to believe that maybe there is a bad sector on the drive. I tried to inspect the drive using smartmontools and smartctl but since it is an external drive, i was not allowed to do so. Is there anyway for me to inspect and fix this drive? I am on fedora ublue-main. The HDD is a 1TB seagate drive.

Edit : I am a linux noob so some hand holding will be appreciated. Also i am looking to use this drive only for low priority media files which i dont mind losing so please help even though it is not the greatest idea to use a failing drive

Edit 2 : It seems my post is not clear of what i am doing. I dont want to recover data from the drive. I want to try to use more of the drive for storing data

Tell the drive to do a secure erase. If there are still bad blocks after that, it is absolutely garbage

Frankly you should never see bad blocks, but sometimes minor bad things happen and the drive has to tell you that this data is gone forever. If you write over those bad blocks at some point, the drive is supposed to remap them to spare blocks and carry on as if everything is okay. If it has run out of spare blocks, then the bad blocks stay forever. A secure erase might give the drive more wiggle room to re-allocate around a larger bad spot, IDK.
