303.0. "DISKCOPY problems" by ECC::JAERVINEN (impersonal name) Thu Feb 05 1987 03:41

Since last night I am a (happy?) Amiga owner... but I had a couple of
problems, too, so I have a few novice questions:

The first 'useful' thing I tried to do was obviously to copy the
original floppies that came with the machine. I bought some TDK
floppies for that purpose (anyone have experience with that brand?).
For the time being, I only have a single-drive system.

TFM says you don't need to format the target floppy when doing a
DISKCOPY, but I found out that it didn't seem to work mostly without
it, the copy would abort *at the end* with something like 'illegal
sector id, copy abandoned' (I got some others I guess too).

Sometimes I managed to copy the disk without any errors but it still
had read errors when using (to the extent of creating a non-bootable
workbench even when the copy ran without error messages).

This was all pretty late last night so maybe I did something wrong...
but I tried to make sure not to remove any floppies while the drive
light was on.

Eventually, I seemed to have made a copy of the workbench that seemed
ok, but I am still a bit worried - do I have problem (in myself, the
drive or the empty floppies I use).

The drive sounds not probable - I could read all original floppies
every time without any problems and could run all the stuff in the
workbench, basic demos etc.

These TDK floppies have a 'lifetime guarantee' - if they turn out to be
so bad, I think the lifetime is a bit short, though...    :-)

And what is the difference between DUPLICATE in the workbench and
DISKCOPY in CLI? At least the volume labeling is different - DISKCOPY
keeps the original name, DUPLICATE seems to call it 'Copy of ...'.

303.1Sounds like the floppiesTLE::RMEYERSRandy MeyersThu Feb 05 1987 05:3010
Re .0:

It sounds like you got bad floppies.  You might want to verify that it
is the disks by buying a box of double sided Sonys to see if your problem
persists.

The manual is right, a disk copy or duplicate do format as they go.

A disk copy and a duplicate are the same except for the differences
you noted.  Both cause the program sys:system/DiskCopy to run.
303.2Some Simple RulesAUTHOR::MACDONALDThu Feb 05 1987 08:0423
    Choosing DUPLICATE is the same as DISKCOPY from CLI.
    
    A few things to keep in mind:
    
    1.  You cannot use the RUN DISKCOPY command line. You will
        almost certainly get a failed DISKCOPY if you attempt
        a background DISKCOPY with the RUN command.
    
    2.  Don't try to save money with single-sided diskettes. Buy
        the double-sided. I prefer Sony after testing many brands
        including Maxell, TDK, Fuji, etc.
    
    3.  Never attempt to remove a diskette until that red drive
        led goes off. I'd recommend waiting an additional 5 or 10 
        seconds after the led goes off before removing the diskette.
        Failure to with for the led to go off is the single greatest
        cause of read/write errors on the Amiga! Rule is to watch
        the led not the requester. The requester always appears on the
        screen before the led goes out!
                                                                
    Enjoy!

    Thanks for the advice... I'll give some other brand of floppies
    a try tonight.
    
    I'm pretty sure I waited long enough (I've read the warnings in
    this file) before removing any disks but it *was* late at night...
    
    But are there two DISKCOPYs? see below...

Note 207.6                   Building a RAM disk...                      6 of 10

Lest someone become confused, there is a program named DiskCopy in both
the c and System directories.  However, c/DiskCopy gets its arguments
from the CLI command that starts it while System/DiskCopy gets its
argument from an Intuition message from the Workbench.  These are two
distinct programs.

    
303.4BAGELS::BRANNONDave BrannonThu Feb 05 1987 13:185
    Are you running Workbench 1.1 or 1.2?
    
    I think 1.2 is when they switched to having one DISKCOPY program.

303.5Only oneAUTHOR::MACDONALDThu Feb 05 1987 14:372
    I believe in V1.2, there is only one diskcopy and its located
    in the system directory, not the c directory.
303.6Was true awhile ago...TLE::RMEYERSRandy MeyersThu Feb 05 1987 16:084
Re .3:

My information in 207.6 was indeed old.  V1.1 had two different diskcopy
programs; V1.2 has one.
303.7ECC::JAERVINENimpersonal nameFri Feb 06 1987 04:3525
    I'm bringing it back to the shop today... sigh.
    
    I bough another brand (BASF) floppies; the first attempt to copy
    promptly failed.
    
    I did some testing last night (a bit earlier so I think I was in
    my full mind). Doing a diskcopy to a brand-new, completely blank,
    unformatted disk almost always fails (mostly after all tracks were
    written and the program does it's final actions; looks like it is
    rereading something, maybe the track(s) containing volume info or
    something).
    
    If I format the disk first and then copy, the copy operation sometimes
    finishes without any error messages, but the disk is still bad.
    Depending on where the error is, I can e.g. work with a copy of
    the workbench but sooner or later I hit a bad track.
    
    Running diskdoctor on the disk (right on the copy, before doing
    anything else with it) *always* found at least one track with a
    hard error (sometimes more). These were on random tracks even on
    the same disk, after reformatting and recopying.
    
    This time I am sure I didn't remove any disks while the light is
    on. FORMAT does one disk access after a *very long* time...
    
303.8...LEDS::ACCIARDIFri Feb 06 1987 07:5318
    Sounds like you must have gotten a bad drive, since I have never
    heard of anyone getting so many bad disks.  Too bad, I hope this
    experience doesn't sour you on the Amiga.  NEC makes the drives
    in early Amigas, you can tell an NEC drive by the loud gronking
    noise that the stepper moter makes when the drive seeks.
    
    Later Amigas use the Panasonic drives, which are quieter, and consume
    less power.
    
    By the way, it is really not necessary to wait any longer than after
    the red LED goes out to eject the disk.  In fact, under 1.2, I don't
    believe an 'Change Disk' requestors pop up until the red LED is
    out.
    
    Anyway, if you find that you need a replacement drive, try to get
    the Panasonics.  One other friend had problems with the NEC, replaced
    it with a Panasonic, and has lived happily ever after.
    
303.9ECC::JAERVINENimpersonal nameFri Feb 06 1987 08:0718
    Don't worry, I love it!! I don't know what drive it has, but I found
    it very quiet, so maybe it's a Panasonic.
    
    Yes, finally I thought it must be very unlikely to get so many bad
    disks - I had 20 TDK disks and tried 6-7 of them, no way - the BASF
    disks failed as well, so...
    
    Anyway, I brought the whole thing back, and as I had grabbed their
    last Amiga and they didn't know when they will get more, I had my
    money back - just checked a couple of other dealers to make sure
    I get a replacement for the weekend... I can't wait to *really*
    start playing with it (so far, I've used 99% of the time to fight
    the bad drive).
    
    BTW, I like the VR241 also - the picture is a bit tiny (as mentioned
    elsewhere in this file, but it can be adjusted). But it's really
    sharp - selecting suitable colors I could even display about 62
    lines of text in interlace mode.
303.10ECC::JAERVINENimpersonal nameMon Feb 09 1987 03:1914
    Well, the saga has ended (almost) happily... I went off to another
    store with my money and got a new one. It works perfectly, no problems
    whatsoever with diskcopy.
    
    Only gripe was that Commodore has run out of German keyboards -
    the thing had a French keyboard!! But not by mistake, they had
    ECOing instructions to turn it into a German keyboard (sticky labels
    for the keycaps). A nice color printed ECO instruction - so this
    hasn't been a surprise even to them. Seems like the Amiga is selling
    better in Germany than in France...
    
    (The broken one I had before had a real german keyboard; in fact,
    I would prefer an American keyboard, but they don't deliver them
    here).
