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.

Trying to re-use some drives with no success (lemmy.dbzer0.com)

I have 4 old hard drives that I pulled from an old Drobo that needs to be trashed. I bought a Mediasonic 4-bay RAID enclosure that I thought would be a good upgrade, but knew going into that the drives may not work because the manual for the new enclosure specifically says to use new drives to avoid problems. The exact product is this Mediasonic one.

I don't care about the existing data on these drives, and that was originally what I thought was meant by "avoiding problems". So I tried just putting the drives in to no avail. They don't show up as drives in the file explorer. They don't show up in "Disks".

I also have an external hard drive dock - the 15 year old version of this one which does let me mount the drives and see them in Disks.

I have tried running "wipefs -a" and I've tried formatting them in Disks with no filesystem specified. I've also run parted on them, but anything I try in parted gives me the error "unrecognised disk label".

If I can't reuse these old drives then the enclosure is of less use to me than I had hoped as I don't intend to buy new drives any time soon.

Is there anything else I can try to reset these drives to a state where they'll act like new drives that have never been used before?

Update: The "tricks" haven't worked so I'm doing the full disk write using dd. It'll be a while before I have 2 disks prepped to try.

Thanks, this looked really promising but didn't work for me. lvremove said it couldn't find the volume group and dmraid said that I have an unsupported sector size and it didn't see any raid disks at me drive location.

I'm currently using dd to write zeros to the drives. I'm not sure how long that will take me on this old USB 2.0 dock.

Hoefully that works. It was hours of trying different formating, zeroing etc, the error it gave me lead me to search and finally get a one liner that fixed it all. But why I didn't add it to my notes is a mystery LOL
