Yeah this is what I’m doing now. I tried all of the tricks but they aren’t working. Unfortunately this dock is USB 2.0 so I think it will take quite a while. These are “only” 3TB drives, but I need to clean 2 of them before I can test. Hopefully sometime next week??? Haha.
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.
I want to use RAID 1 but I’ve tried single disk as well.
hdparm wouldn’t let me run the security-erase or security-erase-enhanced commands. It was indicating an IO failure. I thought maybe that was due to me not giving the drive a file system so I went back to Disks and gave it one, but still no luck. When I give it a file system the drive mounts though, so no actual hardware issues that I can see.
I found a thread on another site about using dd to remove the last 1-10MB of a RAID disk in order to make their RAID appliance see the drives as unconfigured. That’s basically what I’m trying to do here so I followed those instructions but this Mediasonic bay is still not coming to life with the old drives. I might be at the point of sending it back and looking for something else.
Just for completeness, the command used to wipe the end of the drive is as follows where you specify the amount to wipe using the “mb” variable and you change /dev/sdX to the correct drive. From a thread on Stack Exchange.
disk=/dev/sdX && mb=10 && dd if=/dev/zero of=$disk bs=512 count=$(( 2048 * $mb )) seek=$(( $(blockdev --getsz $disk) - 2048 * $mb ))
I’ve never used this before so I’m not sure what to make of it. I am currently letting it analyze one of the disks and it’s seeing a lot of HFS+ blocks (I assume that’s what it’s reporting) and a handful of ext4. That makes sense I guess, since I’m not wiping the drive, just trying to delete any partition info and/or formatting.
The only thing that seems like it might affect how the disk looks when inserted is cylinder geometry but I don’t know enough about that to even guess at what to do with it. Is there something I should be looking for in testdisk?

Why governments would ever use a private service for critical use baffles me.

This is s completely incorrect take on the stock market.
Rule #1 of the stock market is that none understands how it responds to inputs.
Rule #2 is that it attempts to factor in future expectations, so if you wait for something to happen, the impact is already accounted for in the price if the stock.
Market frenzy, people piling on when FOMO takes over, etc all make it impossible to have any level of certainty. So it’s a valid question to ask why all of the current fuckery has not translated into market chaos.
