What does this really do?
AFAIK it overwrites the drive instead of just wiping the directory.
Is this the best way to go before re-formating, or does
"erase drive" in the disc utility give you enough of a fresh surface?
which might have been what you were talking about - but yes - in the end secure erase and secure empty are doing the same thing, which is writing random data over data to ensure that the original data cannot be recovered...
I am refering to external drives.
In Panther (I have an unfinished project) the "secure erase' is not an option.
Erase there is so darn quick, I doubt it is overwriting, as does 'secure empty trash"
which takes so... much longer.
So what is the best option for a clean external media drive in Panther?

this really totally depends on your needs - trashing a file erases it just fine...the only difference that secure offers is that it renders the file unrecoverable should someone take your drive to a recovery center or the likes...
(and even plain erase after a while makes it unrecoverable - the secure just intentionally writes junk over the spaces the file took up right then and there, whereas over time the computer will use that space again and again which is the same thing in the long run)
if you have data on that external drive that is sensitive, i'd consider encrypting the volume with on-the-fly encryption with something like truecrypt - that way nobody can read the data to begin with...but if you just have plain old files on there, a simple empty trash should suffice...
the reason for this question is that a Windows machine with MacDrive is being used to encode video. The resultant file is either incomplete (does not write to the end) or has artifacts at odd points.
My thoughts were that it is reading some undeleted files.
The only other reason I can think of is the 4-pin firewire port in the windows machine is inadequate for the Data comming via the 6-pin FW 400 port on the Mac formatted external drive.
Any ideas please?

ahh - and by "undeleted" you mean non-completely destroyed files? that would be almost impossible - files are deleted from the file system and the fs won't use them again...they just might be findable if you took the drive to a recovery specialist...
