How can we confirm with certanty a USB or Harddrive is not infected after reformatting?
Running the following code on a linux machine returns the partition tables and partial config of the hard-drive and USB devices.
fdisk -l
returns
Disk /dev/nvme0n1: 238.47 GiB, 256060514304 bytes, 500118192 sectors
Disk model: PC300 NVMe 256GB
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: dos
Disk identifier: 0xfbbbaaa
Device Boot Start End Sectors Size Id Type
/dev/nvme0n1p1 2048 2361344 2359297 1.1G 83 Linux
/dev/nvme0n1p2 * 2361345 500103449 497742105 237.3G 83 Linux
Are there any manual checks we can do to ensure sanitation(no infection) after performing
- re-formatting
- deleting the partitions
- remove filesystems
Is there any other steps I am missing, and do the above need to be performed in a specific order?
Does a more comprehensive command/solution exist to wipe a storage device and confirm its cleansed after? Ex md5 hash
