Securely wipe disk media.
dskwipe [options] device(s) [byte(s)]
bytes can be one or more numbers between 0 to 255, use 0xNN for hexidecimal,
0NNN for octal, r for random bytes, default is 0
Options:
-l | --list List available devices and exit
-p | --passes n Wipe device n times (default is 1)
-d | --dod Wipe device using US DoD 5220.22-M method (3 passes)
-E | --doe Wipe device using US DoE method (3 passes)
-D | --dod7 Wipe device using US DoD 5200.28-STD method (7 passes)
-S | --schneier Wipe device using Bruce Schneier's method (7 passes)
-b | --bci Wipe device using German BCI/VSITR method (7 passes)
-g | --gutmann Wipe device using Peter Gutmann's method (35 passes)
-1 | --pseudo Use pseudo RNG (fast, not secure, this is the default)
-2 | --windows Use Windows RNG (slower, more secure)
-k | --kilobyte Use 1024 for kilobyte (default is 1000)
-y | --yes Start processing without waiting for confirmation
-x | --exit mode Exit Windows. mode can be: poweroff, shutdown, hibernate,
logoff, reboot, or standby.
-f | --force Force poweroff/shutdown/logoff/reboot (WARNING: DATA LOSS!)
-q | --quiet Display less information (-qq = quieter, etc.)
-z | --refresh n Refresh display every n seconds (default is 1)
-n | --sectors n Write n sectors at once (1-65535, default is 64)
-s | --start n Start at relative sector n (default is 0)
-e | --end n End at relative sector n (default is last sector)
-r | --read Only read the data on the device (DOES NOT WIPE!)
-i | --ignore Ignore certain read/write errors
-v | --version Show version and copyright information and quit
-? | --help Show this help message and quit (-?? = more help, etc.)
dskwipe -l & lists devices, and exit
dskwipe \\.\PhysicalDrive1 & erase disk once using the byte 0
dskwipe \Device\Ramdisk 1 & erase disk once using the byte 1
dskwipe \Device\Ramdisk 0 255 & erase disk twice using bytes 0 then 255
dskwipe --dod \Device\Ramdisk & erase disk using DoD 5220.22-M method
dskwipe \Device\Ramdisk 0 0xff r & same as --dod (bytes 0, 255, weak random)
dskwipe -p 2 \Device\Ramdisk 0 1 & erase disk 4 times using bytes 0/1/0/1
dskwipe -p 2 --dod \Device\Ramdisk & erase disk twice using DoD method
dskwipe -1 \Device\Ramdisk r r & erase disk twice using weak RNG
dskwipe -2 \Device\Ramdisk r r r r & erase disk four times using strong RNG
Here are some device names that have worked for me:
\\.\PhysicalDrive0
\\.\c:
\device\harddisk0\partition0
\device\harddisk0\partition1
\device\floppy0
\device\ramdisk
To verify a release, download the .zip, .sha256, and .asc files for the release (replacing dskwipe-1.1-win32.zip with the release you are verifying):
$ wget https://github.com/rasa/dskwipe/releases/download/v1.1/dskwipe-1.1-win32.zip{,.sha256,.asc}
Next, check that sha256sum reports "OK":
$ sha256sum -c dskwipe-1.1-win32.zip.sha256
dskwipe-1.1-win32.zip: OK
Lastly, check that GPG reports "Good signature":
$ gpg --keyserver hkps.pool.sks-keyservers.net --recv-key 0x105a5225b6ab4b22
$ gpg --verify dskwipe-1.1-win32.zip.asc dskwipe-1.1-win32.zip
gpg: using RSA key 0xFF914F74B4BB6EF3
gpg: Good signature from "Ross Smith II <ross@smithii.com>" [ultimate]
