I suspect that these groups think that there's actual money to be made in
restoring old media. With a few high-profile exceptions, this is quite far from
the truth.

But for data recovery? Nope. Sorry. Got to be /at
least/ as open as that and
preferably a lot more so. I've seen too much of the squabbling and
in-fighting.
As you know, I've recently discovered TOSEC and have been hoovering up the
media they've been archiving. At least on the Amiga side, the file formats are
completely open: one ZIP file per image, with the contents being a raw disk
dump in the case of floppies (aka "ADF"), and a CUE file plus the raw ISO-9660
filesystem and uncompressed WAV files for CD-ROM media.
I note that my very slow-moving archival project of my Amiga media also
produced files that are bit-identical with TOSEC, which is encouraging. I don't
know what they've been using to do the transfers, but I've been using an Amiga
1200 with a CF card and a copy of "SuperDuper" configured to dump to file
instead of another floppy. On the modern hardware side, I just used a USB CF
card reader on a Linux box (Debian natively understands RDB and FFS) to read
the data, and I slapped together a Perl script to do the postprocessing from
SuperDuper's custom IFF disk image format into the de facto standard ADF
format.
I'm not quite sure how I'm going to read all the HD disks I wrote on my
somewhat ill Amiga 4000 that isn't really up to being run for long periods to
do the data recovery. (Plus it doesn't have a CF slot.)

Fallout from
all of this still being perceived as warez?
Perhaps so, but while that might be a
factor, it can't be all of it, surely.
Reading between the lines, TOSEC pretty much started up as an Amiga warez
operation that was collecting stuff that's basically abandonware at this point.
Piracy of recovery software is another factor, at the
least, I am sure.
If anybody wants my Perl script, they're welcome to it for nowt :)
