I have some drives of various sizes, 1TB, 2TB etc. I am currently working with a 2 TB drive. I place it in a powered external USB-3 drive enclosure. I can see it in lsblk as the correct size (as SDA) , but the disk manager does not see /dev/sda, and fdisk only wants to let me create a 5 GB partition.

If I dd if=/dev/zero of=/dev/sda bs=400K status=progress writes 5 GB and claims my 2 TB drive (In this case) is full.

Is there a way to reclaim this drive? Any information on the drive is unimportant.

Some drives work fine. Some fail. Some work fine then fail later. But it seems hitting them with gparted to create a single ext4 partition works, brining a 5gb drive back from that state and allowing writes if I write to the partition. If I try to zero the raw device it still fails at 5gb.

Drive(s) because I have a 2tb drive (I am currently working with) and several 1tb drives and many smaller ones.

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.
