how to protect sheet

[govind patel]

Hi, I have created 35 identical worksheet for my workbook. there are some identical cells that I need to lock. is there an easy way to protect all sheets in the workbook in one go rather than protect sheets one at a time.? Thanks

You could run a macro like this:

Sub ProtectSheets()
    Dim w As Worksheet
    For Each w In Worksheets
        w.Protect Password:="topsecret"
    Next w
End Sub

Note: When you add these other drives as system favorites, they will obviously only mount if they have the same password as the system drive (they also won't show up in the volume manager, even though they are already mounted.) Typically you can boot into WinPE and use the portable version (once you install it to your USB drive.) You can use that to backup the volume headers into a separate folder, and even keep all your restore disks in zip format on a single drive (even going in to create restore disks out of the USB drive, so you don't have to have the bootloader stored on the drive itself, if that's actually a real concern.)
