After erasing 80 gigdisk,
went to get info
80 Gig Drive
Capacity 74.52
Available 74.49
Used 34.3 MB

So what does used mean ?
Does it mean that 34.3 has already been written on the Disk but its somehow made redundant and probably available as recoverable ?

I attempted a 'zero disk erase' but have discovered that my drive is not an Apple recommend disk and therefore can't perform this. Conducted a search for third party ware to do this but the only two apps I found are for the corporates.
Anyone heard of a freeware or shareware app that performs 'zero disk erase' suitable for using with Jaguar ?

Please don't refer me to Terminal, I'm a novice.

Try initializing the drive again and see how it comes out...I've had to do it a few times in a row in the past in order see nothing as being "Used"...especially on certain brands of USB Memory Keys, etc. etc....

I give up what piece of Apple or other software do use to initialize with. I can't see anything in Disk Utility that says that word ?

I got given a copy of Norton Systemworks this morning and ran Comletely Wipe Disk. And what you know after two hours ana then went to get info only to find that it still said 36 Gigs Used. Must still be recoverable even though when running Nortons the program warned me that nothing will be recoverable and if this is so why does get info still tell me that 36 gig is used ?

A certain amount of space is always used for the disk directory, and the space occupied grows larger as disk size increases. I wouldn't worry about it.

If you are keeping it for yourself, no need to worry. If you are giving it to someone else, remember that files on an erased disk can be recovered with common tools from Norton, Alsoft and Micromat. Your idea to zero it would be the ideal solution, but if Jag won't do it there is shareware on www.versiontracker.com that will. Here is an example I found, got 5 stars. (I have not used it nor do I have any affiliation with whoever makes it .)

Best of luck
