absolute weirdness...
I have an old Iomega drive with a double option for connection: FW 400 or USB (2.0)
I haven't used it for years (occasionally on Windows 7 and MacOSX, which version I don't remember)
So I plugged it to my Powerbook, started from OS 9.2.1, the "initialize" window came up, I did it: MacOSExtended => fine, it mounted
Ok I then decided to partition it: the process failed, the disk was unmounted
I restarted and surprise, surprise the disk was there on the desktop but with a lock: write protected !!!!
Kay, I started with Tiger, using Disk Utility I managed to partition it. Restarted with OS9, dang, both locked !! They're usable with Tiger (read and write)
Now, the funniest part comes with this: I plugged the Iomega drive via USB. Window "can't be read, initialize blah blah popped up again" and you know what: disk mounted on the OS9 desktop, read and write
What follows is even greater in terms of weirdness: USB 1.1 on a G3 is not a feast so I reconnected the Iomega drive via the firewire port, relaunched OS9 and dang: read only, write protected !!
Leaves me speechless. But I think my dreams of having bootable partitions on an external FW drive are rather uncertain. Mother Puss Bucket !
