2709.0. "TowerAmiga => Bad Floppies?" by MUNICH::CARLI (Bernardo da Vinci - the Amiga genius) Tue Jul 04 1989 13:26

I'm really a bit frustrated with my Ami at the moment....
Two weeks ago I added a 2090 HD-Controller with a RD53. I also decided
to move my A2000 into vertical position like a tower machine. Now I have 
really plenty of room on the desk for the keyboard and monitor - BUT
it seems that I now have some problems with the disk drives (two original
Chinon drives). The number of read/write errors has raised significantly.
I reformatted some of my disks - but after using the Disks a few days I
encountered the same problems. 

Has anyone of you tried using his A2000 in "tower" position? What experiences
do you have?
Could the problem also have to do with the 2090? 
The last thing I would suspect is a defective CIA (Complex Interface Adapter).

    When I put my Amiga in a tower position I experienced exactlt the
    same problems as you are having, at the time I didn't have a hard
    disk either. Unfortunately, I've resorted to laying it flat again.

    I've used my AMY in that kind of position nearly two months, and the
    only problem that I've had with disk drives is that the boot drive
    doesn't read BOOTBLOCK correctly on some disks, the problem has only
    limited to MFF labeled disks, and the answer might be that the lower
    head doesn't have the same contact pressure when in flat position.

2709.3Mine is o.k.GLORY::SPATOULASDon't Automate the Past...Invent the Future...Wed Jul 05 1989 12:238
I have been using my Ami in the horizontal position for almost a year now. 
I have not had ANY problems ..... Are there any alignment programs ??

In my C64 days I had bought an alignment program and had done it several 
times...

...gss...

    I think I've seen some programs which TUNE the drive, I'll check them
    for tomorrow if I can only locate them. One of them might have been PD.

2709.5maybe different drives?MUNICH::CARLIBernardo da Vinci - the Amiga geniusWed Jul 05 1989 14:067
    
    I suspect that the floppy problems mostly have to with the manufacturer
    of the drives. Here in Germany most of the original drives are from
    Chinon. My old A1000 (yes I still have one...) has a Panasonic drive.
    What drives are in your Amis?

2709.6Check for RFI from Monitor!OTOFS::B_CORBINBRIANWed Jul 05 1989 20:216
    Before you do anything drastic try moving you monitor away from
    the floppy drives. There may be some stray radio frequency interefence.
    This used to be a problem with an AppleII clone of mine when I tried
    to put the floppies next to the monitor from their ususal position
    under it.

    >What drives are in your Amis?
    
    Well, I have in my A2000 model-A an CHINON drive, which has worked 
    quite perfectly.
    
    To the previous note that I wrote about the tuning programs for disk
    drives. I didn't found programs dedicated to tuning but from an
    Lake Forest Logic Inc. I did found some CLI-based utilities that
    have some tuning controls, but I'm not sure about do they tune just the
    info on the disk or something more.

2709.8Towers are great...TEACH::ARTThink the UNTHINKABLEMon Jul 10 1989 12:577
	I've had my A2000 in a tower-stand for over a year now; I've
	got the stand sitting on the floor next to my desk.  I've never
	experienced any problems whatsoever either with my floppies
	or my hard drive.

    Sounds like a nice way to free up my desk.  Where can I get a stand for
    a 2000?
    
    thanks,

    BTW I assume you leave the floppy drives on the top???  Otherwise
        the harddisk would be upside down and I think that may be a no-no.

	I'm just using a standard IBM-clone tower stand, and yeah,
	the floppies are up top.  I've got the whole tower sitting
	on the floor -- saves LOTS of room.
