How to check new hard drives with badblocks

badblocks.txt

badblocks -b 4096 -p 0 -s -t 0 -v -w DEVICE [LAST_BLOCK] [FIRST_BLOCK]

	-b block_size (4096 only works up to 16TiB drives, consider using 8192 for up to 32TiB, or 16384 for up to 64TiB. Default is 1024)
	-c Number of blocks which are tested at a time (Default is 64, consider increasing to speed up the process, 64*4096B=256KiB)
	-p num_passes
	-s Show the progress of the scan
	-t test_pattern
	-v Verbose mode
	-w Use write-mode test

Shows output similar to this: Checking blocks 0 to 1953512447
When cancelled with ctrl+c: Interrupted at block 284489984
To continue: badblocks -b 4096 -p 0 -s -t 0 -v -w DEVICE 1953512447 284489983

A more modern equivalent would look like this:
badblocks -b 16384 -c 512 -p 0 -s -t 0 -v -w DEVICE [LAST_BLOCK] [FIRST_BLOCK]

It writes/reads 512 blocks of 16KiB (so 8MiB) at a time on drives with a capacity of up to 64TiB).
