Hey guys,I have 3 hard drives connected to my computer 1 contains my operating system which is windows 7 and the 2nd contains all my games and the 3rd contains information which i dont want which is a total of 72gig. I wish to erase the 3rd hard drive. I have downloaded "DBAN" and put it on a cd to boot of. Do i need to take the other 2 hard drives out for safety and boot of my cd via the bios.Regards Alan

I wish to erase the 3rd hard drive.

If you simply want the drive to be empty there's no need to do more than format it under Windows 7 - if you do not select the Quick Format option, then the drive will be zero-filled, obliterating its previous contents and making it available as an empty drive.

This assumes the drive is not partitioned into more than one partition.

If you particularly want to use DBAN, then it is indeed safest to disconnect all but the drive you wish to wipe, to save having a disastrous accident. But it would seem to be rather a waste of effort if a full format will suffice.

If you need more direction, give more detailed information about the setup of the drive in question, especially if this is not for the system in your sig.

Thanks for the reply Platypus, i just would like to totally erase everything on the drive and then use that drive for my video editing. I have no partitions set up.I was thinking of using DBAN as i read that just right clicking on files and deleting them does not get rid of everything correctly.I was going to format the drive after i erased it. Whats your view.

To simply clear the drive for re-use, DBAN is way overkill. It's tedious to completely empty a drive by doing multiple file deletes, and they'll unnecessarily be put through the recycle bin first unless you specify otherwise, and some will be left there unless you finish by emptying it. So since you don't want to make any change to the drive beyond emptying it, there's little need to do more than a quick format. This rebuilds the file system to the state of a fresh empty drive.

What you may have seen about files not being properly deleted is probably the consequence of a delete leaving the old file contents still on the drive, and able to be recovered later, which can be a security risk in some circumstances. In some cases this is a good thing (accidentally formatting the wrong drive...), but for your purposes doesn't matter at all. What you put onto the newly formatted drive will just write over the top of what was there before.

If you do a full format, it will take longer but in Windows 7 will overwrite the old files with zero values (this didn't happen with XP or earlier). One possible advantage of this is if there are any bad sectors on the drive awaiting re-assignment, it will probably be done at this time. But if the drive has bad sectors, it's not in good condition anyway.
