Retrospect said this is not their software cause. Fine but I asked them for help to remove a locked Retrospect file, whether it needs unlocking before trashing or not doesnt matter to me.
Been on the forum at Lenovo who now handles the iOmega product line support and pretty much the same Unix commands. I tried it both with sudo and no sudo while in Administration control of my machine on both osx 10.5 and 10.7.x machines but still nothing.
I did wind up getting a full working trial copy of Retrospect for both OS's but that doesnt help.
Although the Finder's inspector window says its now formatted in Mac Extended format, it actually isnt. It is still not available for drag and drop or Time Machine access.
It does show up in Disk Utilities just once before I try force reformatting (erase is only available in the app, not format) with hopes this would work but it doesnt. Unix commands dont give me this response but the disk utility app does: "optical erase failed; not completed or completed with errors. See diskrecording.log (from in console) for more information"
Console app shows this error in more detail:
"Disk Utility: Erase started, Sat Oct 26 11:23:05 2013
Disk Utility: Erasing CD-RW media in Iomega RRD 83.B with generic profile via FireWire.
Disk Utility: Erase failed, Sat Oct 26 11:23:07 2013
Disk Utility: Erase sense: 5/20/00 Illegal Request, Invalid command operation code
Disk Utility: Erase error: 0x80020022 The device failed to respond properly, unable to recover or retry."
It does show up in Retrospect Express accessibility, but dislike the software so much I would prefer to not use it. Looks to me like the same interface and horrible GUI from the OS 9 days, when it was a pain to use too.
Pretty much out of ideas...
