(OT) SmartMedia un-erasing - help?

You probably want conv=noerror,sync - check the manpage - but that's not the problem. I'm not that familiar with Tiger, but I feel reasonably sure you're using the mount point rather than the mount-from device node. Check mount(8) and see what it prints; if there's a line listing /Volumes/Untitled and it has a path under /dev/ on it, that /dev/ path is probably what you want. (If not, this is a way in which Tiger is non-Unixy and I'd have to ask someone who really knows Tiger.) This is the flash analog of opening up a traditional drive in a cleanroom and using an atomic force microscope to image the magnetization domains. I'd be surprised if it could be done at all without taking the top off the chip and using something like an AFM on the memory cells, and possibly not even then. I've never even heard of it being done, but I'd be astonished if it were cheap. But, until you get a good dd image of the unit, I'm not going to go pessimistic about recovering it. /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML mouse at rodents-montreal.org / \ Email! 7D C8 61 52 5D E7 2D 39 4E F1 31 3E E8 B3 27 4B
