I’ve been messing with my flash drives trying to follow some random documentation with dd and now both of my flash drives are reporting 0 bytes of free space. I was trying to clear out everything and start from scratch as if they were new. I wonder if there are any program out there that can just sudo reset-everything /dev/sdX
Use something like Gparted and delete all partitions on your flash drive and just make a new single primary partition.
Block devices are simply devices that hold data. That’s all. For a block device to be “formatted,” you typically want a partition table, a partition, and a filesystem in that partition.
For flash storage, the most common off-the-shelf solution is a DOS partition type with a single partition that occupies the entire storage, and a FAT32 filesystem.
On larger or more modern devices, you’ll typically see a GPT partition table with a single partition with exFAT. This setup allows you to store files larger than 4 GB.
You can simply use
fdiskto create or modify a partition table and create a partition. You’ll want to use a mkfs tool to create the filesystem.…
$sudo sgdisk --zap-all /dev/SD{x}
$sudo wipefs -a /dev/SD{x}
The first wipes any existing partitions or data that exist.
The second wipes any data in the table headers if anything is left?
Those have worked for most times I needed it
sudo gparted /dev/sdXYou have blanked the partition table, gparted can create a new one with a friendly GUI
