confidential info on old harddrives.

Let's see. I have enough old 4096s to make a decent R.A.I.D. And 225s, 412s, And a lot of other old drives and diskettes. But many of them were parts of systems on which I worked on source code of a little bit of value. (enough so that there was actually a break-in attempt at theft once! But the casing was so clumsy that all that they got were some diskettes clearly labelled "V2.4 source code self-extracting archive", that actually contained a trojan to wipe hard disk directories.) It would be a hassle to reassemble a machine just to check the drives to make sure that they were all erased properly. So, should I give the ones that I no longer want to somebody who acknowledges intellectual property rights and would HELP if I screwed up and made a mistake; or should I let somebody have them who feels that whatever is on them is now theirs, and would RUN a self-extracting archive? -- Grumpy Ol' Fred cisin(a)xenosoft.com
