I've never had to do that, I just write to 'em. for what purpose or need would one format one? thanks! -- ---- Fred Smith -- fredex at fcshome.stoneham.ma.us ----------------------------- Show me your ways, O LORD, teach me your paths; Guide me in your truth and teach me, for you are God my Savior, And my hope is in you all day long. -------------------------- Psalm 25:4-5 (NIV) --------------------------------

I am assuming (and we all know what that means :) ) that the OP has such a disk. Otherwise, I can't think of another use case where one would format an unused drive, but there may be one. -- Scott Robbins PGP keyID EB3467D6 ( 1B48 077D 66F6 9DB0 FDC2 A409 FA54 EB34 67D6 ) gpg --keyserver pgp.mit.edu --recv-keys EB3467D6

I am assuming (and we all know what that > means :) ) that the OP has such a disk.I write to RW media all the time without formatting it. I might "blank" it, but that isn't the same thing. After posting I realized that one might want to use a UDF filesystem on RW media, and I suppose for that purpose one would need to format it, though I've not done that on a CD or DVD, only on USB. -- ------------------------------------------------------------------------------- .---- Fred Smith / ( /__ ,__. __ __ / __ : / / / / /__) / / /__) .+' Home: fredex at fcshome.stoneham.ma.us / / (__ (___ (__(_ (___ / :__ 781-438-5471 -------------------------------- Jude 1:24,25 ---------------------------------
