    Deleting files from removable drive

    I am trying to wipe a hard drive from a Win 7 laptop that died. (There was a lot of financial information on it.) I am using Win 7x64 on the new machine, and have a gizmo that accepts the bare drive, it appears in Explorer as H, I, & J. Most files on each partition are deletable, but some are remarkably stubborn. One for instance is an empty folder "J:\CTemp". I have no idea what created that! I checked the Properties, Security, Permissions, it shows "Everyone" & "Full Control". However, Delete is not listed under the Permissions, and it won't go away. This might not be a big deal for just an empty folder, but the H partition there's the original Windows folder, and needless to say it isn't going to go quietly either.

    I tried Move on Boot, but it won't delete files on external drives. I tried Disk Management. The H partition is shown as Primary & Healthy; I & J are shown as Logical & Healthy. One of the options is to Delete the partition, if I do that will I leave recoverable information on the drive? Should I delete all the partitions and then format the drive (not quick format)?

    Any suggestions appreciated,

    David

    Yes, delete the partitions, create one or more new partitions, then format each partition.

    Thanks Coochin, but I had already launched into the Delete/Format before I saw your response. I don't suppose Boot & Nuke would find much now.

    You have to be careful with DBAN as it wipes any disk it can find - not necessarily what you want if you want to wipe just one attached disk. At least that's what I understand from the documentation.

    Re-partition and format doesn't necessarily clean the data but DBAN definitely does. It depends on how much security you want.

    cheers, Paul

    p.s you only need one random data pass with DBAN.

    The old DOS "FDISK" command will remove ANY partitions on a HD. (DOS, NTFS or Linux)

    And the DOS Format command will scrub a HD, writing over every sector, to prove whether the sector is 100% reliable or not.

    I keep both DOS commands on my DOS Utilities CD (bootable, of course)

    There's no need for any Retail software to do such a simple job as refreshing a Hard Drive.

    Note that MS-DOS utilities only support the old FAT file systems, not NTFS.

    If wiping any possible chance for file recovery on the old drive is important to you then a simple deleting of partitions, reform partition(s) and quick format will not wipe the drive. Files can still be recovered until they are overwritten.

    If you did a normal (long) format during the Win7 install--which would have taken some time to accomplish--then the surface was completely overwritten and no file data is recoverable.
