besides, you don't have to erase the hard drive if all you are trying to do is clean it. just kidding i know what you mean. you can erase a hard drive with just about any type of OS install disc. just delete the partitions using the partitions manager then exit without installing. Linux Ubuntu is probably your best bet if you can't find a Microsoft disc.
/dev/sdb tells me you are running a Linux system, not windows. And dban is a "secure" disc wiper program. Finally, /dev/sdb is not necessarily a USB device. Since nothing in your post indicates that this is a USB device, why did you make that assumption?
only new when it comes to linux ,and only use a live Linux ,but i think /dev/sdb is the second disk in the boot menu ,and a usb would show as sdd1 because it a removable device and not hard disk
OP cold be using a bootable disk like Dariks Boot and nuke on one of the many othere boot disk around , on a windows install

No, not really. With current systems, usb drives appear as /dev/sdx where x depends upon what slots are available. If you have one physical drive and then boot, then it is /dev/sda. If you then plug in a USB drive (hard drive, thumb drive, it doesn't matter) it will be /dev/sdb.
Understood. As each drive is detected by Linux, it is assigned the next available device id/slot. The boot device should be /dev/sda. Assuming /home is in an LVM group, then each physical drive will be /dev/sdb.../dev/sdx. On my system, the /home lvm is a 4 drive group, so it goes from /dev/sdb.../dev/sde. Then I have a 4 drive array which is detected next, and each physical drive is /dev/sdf.../dev/sdi. Finally, my other drives are /dev/sdj.../dev/sdm. After the system was started, I plugged in a USB thumb drive, which registered as /dev/sdn. Are we confused yet? :-)
Anyway, this is why I label my drives / file systems. Mounting them is a lot easier. So, in /etc/fstab, I mount them using the LABEL=name syntax. My array is named afs-ts02, the /home lvm is mounted by its lvm device name, /dev/mapper/VolGroup00-LogVol00, and the additional drives are labeled as afs-esata-1 through afs-esata-4. I had another drive (afs-esata-5), but it is starting to fail, so I leave it off most of the time. When I get a new drive, I'll copy it to the new drive and it will then become /dev/sdn instead of the thumb drive.
lol. many many years ago ,,i say new to linux but actuall made my first live cd/dvd 7 or 8 yrs ago ,i have a Live Puppy Linux on a multisesion DVD [can make changes and save to the dvd when i shut down,],play it with rarely

Well, I use Linux almost exclusively at home, and mostly at work as well, though I have Windows XP running in a VM at home, and my work laptop runs Windows 7, but with a Linux Vm on it for system software development and testing!
