Micropolis - moon or bust?

Hi! Have anyone noticed that Micropolis hung up their website and fallen off earth's face? This done, I have a question: I have a 340MB micropolis scsi, model 1684-7 that has problems, terminated properly BTW. I'm not sure which bad platters or sick logic board? Everything were set right. I used spinrite 3.x to test the surface for short time at level 6 after proper LLF and fdisked (lot of seeking but finally goes through), Again seekings during the formatting. I get 16K worth of bad sectors in 2 places but what about the first few tracks which I got the clue of appox 290mb formatted that I suspect due to bad sector reaasignments instead of correct appox 330mb. I hate to break it open, finding out it's good platters! So, I have your expert experience on this! If there is so cheap 400 to 500mb SCSI hd and with gusto in performance then I would know that bad hd I have can be tossed without concern. By the way, I have a ST11200N, giving me problems as well, spin sounds good to me but logic board could be at fault, I get errors in r/w and formatting. Any known problem histories are what I'm looking for. Thanks! *AND* Merry Christmas and Happy New Year to all! Jason D.
