After looking in= to various solutions, I'm not getting the warm fuzzies about finding the ne= cessary hardware on my first shot, these sorts of hardware specifics are no= t my strong suit. The story I got is it is from a working system, so could= possibly have artifacts, but at the same time, I've already sunk a little = over $1,000 into getting this, I'm hesitant to drop more on hardware I'm no= t 100% confident is correct for the job. The later SCSI specs are pretty forgiving as far as backwards compatibility goes, a U320 drive will run fine on basically anything with 68-pins other than HVD which you aren't likely to encounter. U160 and up are alwasy LVD. There are some U320 PCIe cards but they seem to be pricey these days (on the order of $100). If you have a system with PCI (or PCI-X) you can pick up a capable card for $10. An internal cable with a built in terminator is about $15 and that is the only other thing you need. Typically you can just do a 'dd' of the drive to get a raw image from any fair modern UNIX. Then you can try 'binwalk' to see what the disk structure is like.. hard to say where to go from there without seeing the output of this. > > Does anyone have any recommendations, whether a service, hardware, anythi= ng, that I could use to try and get at what is on this disk? Even if it's = just sending it off to someone along with enough storage for them to make m= e a dd image of the thing, I just feel so close yet so far on finally figur= ing out if I've managed to land a copy of DMERT. If you really need to outsource it, I have the requisite equipment. Might take me a couple weeks to turn around due to work pressures. > > Thanks in advance for any advice, I'm really hoping that the end of this = story is I find DMERT artifacts to get archived and preserved, that would b= e such a satisfying conclusion to all this 3B20/5ESS study as of late.
