Why are 1.92/3.84/7.68TB hard drives the standard?
uz flag

For SSD drive, I often see specifications like 200GB, 400GB, 800GB, 1.6TB, 1.92TB, 3.84TB, 7.68TB (For example, HPE 7.68TB SATA 6G Read Intensive SFF SC Multi Vendor SSD)

Is there a hardware/architectural reason that makes it go from 1.6TB to 1.92TB, instead of having 3.2/6.4TB hard drives?

How to recover corrupted HDD with LUKS encryption?

There's a 1TB HDD which is somehow corrupted. It has only one partition and it's LUKS-encrypted, as far as I know. The password is known. The HDD used to prompt for the password right after it was mounted, but now it doesn't mount automatically as before, and there's no password prompt anymore. Also, the device doesn't appear in the list of available devices in Linux Mint's GUI. However, it's discoverab ...
