f3probe

Probe a block device (e.g. a flash drive or a microSD card) for counterfeit flash memory. See also: f3read, f3write, f3fix. More information: https://manned.org/f3probe.

• Probe a block device:

sudo f3probe {{path/to/block_device}}

• Probe a whole block device destructively, without preserving any data (required for raw devices with no partition table):

sudo f3probe {{[-n|--destructive]}} {{path/to/block_device}}

• Use the minimum amount of RAM possible:

sudo f3probe {{[-l|--min-memory]}} {{path/to/block_device}}

• Time disk operations:

sudo f3probe {{[-t|--time-ops]}} {{path/to/block_device}}
