Windows 10: DOS format command

DOS format command -- a few questions

1 Format /p:2 would do an initial sector zero-fill followed by 2 random fills. What's in a random fill? Is it a sector-long string of a single non-zero character, or a random string of different characters e.g. x'7f38e2 ...'?

2 Is there any way to break up multiple randomizer runs? Based on % complete estimates, the zero-fill would take 7.5 hours on one of my old HD's, and each randomizer would add another 7 hours. I'd like to be able to break up the work into separate chunks rather than a single big chunk.

Thanks and regards, John

How To Format A Write Protected Flash Memory ?

¿You already tried this one?...

Run CMD


1. diskpart
2. list disk

Then in the 3º step, put the correct number of disk in the list for the usb flash (if it's listed in disk 3, then you'll have to write select disk 3).

2. select disk #
3. clean
4. create partition primary
5. select partition 1
6. active
7. format fs=fat32
8. assign
9. exit

with that commands you will format the flash drive in fat32, if you have a large drive you can select also "format fs=ntfs" in step 7.

good luck!

Need to initialize it as GPT disk type with HD > 2TB:
From Admin command prompt:

Open Disk Management and initialize the disk as GPT, create simple then format.
