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.

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.
