Last week, in the middle of debugging Kermit (and making headway) the 6070 disk dropped dead (I think the technical word for it is 'sh*t the bed'). I was operating it remotely (ssh to host machine w/minicom) so I couldn't see that the power-OK led went out. Unloaded the heads, powered off, checked for massive damage, etc, powered on, no POWER OK or LOAD. Off for the night. Next day, powered on OK, (power OK led on), LOAD, READY (headload OK) but can't boot; the bootstrap always seems to get wiped out whne the machine shutsdown badly. Can't write bootstrap (from tape). Diags failed; long story short, all of the disk logic seems good, media is fine (whew!), seek and format, but no read-data at all -- can't read sector address headers post-format. All four surfaces the same, so it's not heads or stuff up to the input mux, diags seem to think it's likely in the disk drive. I hope to put the 'scope on it tomorrow and begind debug. The power-OK failure bugs me, though if some driver was able to drag a power supply out of spec for many minutes you'd think there would be evidence of, let's say, excessive power consumption (aka smoke'n'flames). This ain't CMOS. We'll see. Lost a bit of work, but everything was backup onto tapes (multiple tape files each tape, plus multiple tapes). Can't wait til Kermit is running!
