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.

Handling USB-attached Hard Drives. Am I doing it wrong? (lemmy.one)

I have a stack of SATA hard drives that I need to erase.

I have a USB drive dock, a box that a drive can be set into that connects to my computer via USB-3.

I am using DD to write zeros to the raw device, in this case, /dev/sdf.

No matter the actual size of the drive dd stops at about 3 to 7 gb. These are 300 gb to 3 TB drives.

I am not mounting the drives, but I do ensure they are visible to the system with lsblk. To change drives I turn off the dock. The drive then disappears from lsblk. When I insert a different drive and turn the dock back on again /dev/sdf re-appears.

Are all my drives bad? If they are I will need to have them "professionally" destroyed at about $25 a drive.

It seems more likely that your usb adapter is at fault here ...
