4738.0. "rd53 + mountlist, HELP" by BAHTAT::BAHTAT::HILTON (How's it going royal ugly dudes?) Tue May 14 1991 09:01

    HELP!
    
    I bought a second hand 2090 controller and mon ami jr to plug into my
    A500. It also came with a ST-225 20MB hard drive. I am having great
    difficulties getting it to work.
    
    After I got the Amiga to recognize the hard drive it worked, for a bit
    but gave me guru's and system hangs occasionally. I reckonned it was
    'cos the board was loose in the slot, so I rigged up something to hold
    it firm. Now it works occasionally, but still guru's and hangs. I can't
    even format the disk. prep works, but format hangs and then gurus. So I
    decided maybe all the mucking around at the start had damaged it.
    
    Do people thing it's a h/w problem with the board or the disk?
    
    SO if I assume the actual drive is kapput, then I have an rd-53, I
    could try. SO I switch off, boot and then prep?
     PROBLEM  - I don't know what answers to give prep for the rd53. Do I
    need to alter my mountlist for res0: first? Will I have to create a
    mountlist entry for the rd53?
    
    Could someone post mountlist entries and 'idiots guide'!!
    
    I'm at a customers all week, so if I can't get it working this coming
    weekend it's going back!
    
    Please help, when it worked it was great and the speed differential
    between floppies was good. If it doesn't work that's my birthday
    present down the tubes ;^(

    I think the RD53 is 1024 cylinders 8 heads 17 sectors = 71Mb
    
    But just to test it, make the partition smaller (you waste less time
    formatting the drive), something like 50 cylinders 4 heads and 17
    sectors, the drive will still work with these numbers and you yill be
    able to test the drive/controller faster.

    PS don't forget the 2 cylinders reserved by AmigaDOS and make
       a mountlist to match the size you want.
4738.2Go on, do me a favourBAHTAT::BAHTAT::HILTONHow's it going royal ugly dudes?Wed May 15 1991 10:368
    Aww, 
    
    Go on someone with a working RD53 put their mountlist in here. I've
    searched the plethora of hard, disk, rd etc note sbut to no avail.
    
    Cheers,

4738.3here's mineCGOFS::DREWSteve DrewWed May 15 1991 16:4146

Note: my first partition is 4.5 megs, enough to hold workbench stuff for
autoboot. And since it is defined by prep (using RES0:) is does not have
a mountslist entry except for the RES0: that is only needed when mounting
RES0: in order to PREP the drive.

Note the Unit=1 (that may mean I have my RD53 numbered as Drive 1).

Heres the RES0: mountslist entry and the second partition.

hope that helps,

Steve.
