All you need to do is incorporate the blood sacrifice into the FPGA.
That's the way we fixed SCSI issues in the old days.

The advantage would be that there are iSCSI devices and implementations
already out there. There are downloadable VMware appliances to handle it,
which makes the contemporary end a snap.
I think there'd be a reasonably big market for a USB breakout device
of some kind. I've tried several USB to IDE/SATA gizmos on dozens of
semi-flakey drives, and WinXP tends to go into la-la land if the
USB side isn't responding the way it should (which it'll do if the
hard drive isn't responding the way it should.)
I'd pay $200-300 for a device that would show me in great detail
what's wrong, allow for a write-protect to keep Windows from writing
to it, and/or allow me some alternative methods of getting to the
drive's data. Sounds almost like some forensic recovery devices,
but with more debugging output.
Same for old SCSI, no? Somewhere in my junk piles I have a SCSI
pass-through board with an LCD display that showed a count of
blocks read/written. Why not more info?
