[comp.sys.atari.st] Extened Format Programs...

Yonderboy@cup.portal.com (Christopher Lee Russell) (12/10/90)

What is the current verdict on all of the extened format programs I have
ran across.  Is it safe to format a disk with these programs (is the data
going to be secure).  I have a program that formats 82 track and gives
me near 800K is this OK?  Also what is the twister format, is this good?

        ....Thanks ahead of time... .....Yonderboy@cup.portal.com

I've been formatting my disks at 82/10 (828K -- the damn GEMDOS bug won't
recognize two sectors on the disk, so I don't get 830K) for 3 years, ever
since I've had an ST.  No problems.  I also format them with a 'twister' or
'skew' option.  I recommend DC Format (version 3.2 is the latest, I think)
and Mystic.  Mystic automatically formats with skew and the nice 
thing is that it formats in the background.  I also recommend DESKFMT 
which is in RAMPLS12.LZH (or similar filename).  I have NeoDesk 3.0 
and TOS 1.6 so I use those.

(Damn vi editor!  ARGH!)

Probably, but that depends on your particular drive.  It's beyond the specs
for the drive to ask it to go to track 81 (track 80 is the "official" max
number of tracks.) There is no error returned from the drive if it can't get
to track 80 or 81 (the first track is track #0), it will simply go to track
79 and act like everything is fine.  The only time you'll know if it worked
or not is if you fill the disk completely and see if all of the files are
complete and intact. Some drives can do it, some can't.  I don't even think
you can generalize between manufacturers, it depends on the individual unit.
If it works the first time, however, you should be able to count on it.

Some software will put extra sectors on every track, 9 is standard, I think,
but some will try to go for 11.  Once again, I don't think that you'll get
an error if it fails.  Instead of the head not making it to a track, as
above, the extra sector method will try to keep writing sectors to the same
track, hoping that the last sector doesn't overwrite the first one(s).

Some software will combine both of the above methods and can get up to around
1MB, I think.  However, I advise you NOT to do this on your backup floppies.
Especially not method #2 above.  I just don't trust pushing the hardware beyond
specs. I bet that over the months/years, you'd end up with a corrupted disk.

>Also what is the twister format, is this good?

Twister is to get better speed from the disk, not more storage.  What happens
is the sectors are staggered from track to track in such a way that reading
long files will be quicker because you save some extra revolutions, the drive
won't have to wait for the sector to spin under the head.  Twister is reliable
since it just staggers the sectors. You don't get any extra storage.

While I had my ST, I ALWAYS used 10 sector formats and I don't I
ever lost any data due to that.  As Ed mentioned, you'll get 
slightly speedier performance if you set the interleave for
1 sector.  I always used HyperCopy and Format11 by Matt Orsie.
Almost any formatter will do the job, but you should look for
one that also VERIFIES the format to make sure everything is OK.
As for 11 sectors, well....it never worked on my ST and always
munged files.  Apparently, your drive has to spin at EXACTLY the
proper speed (300rpm) for it to work.  I wouldn't trust any
important data to this format.

Cheers,

Chris

Does FORMAT.{PRG,ACC} (posted to atari.archive, I believe) VERIFY the
format?

Hyper Format by A german chap that gets on here "Brod" is i think part
of his name, Please excuse not knowing it, but his Formater works very
well, and has the Option to Verify, and will do PC Formats, and 11
sector formats, and this one works !, but don't know if it has the
3 sector FAT option, as the Atari uses a none standard 5 sector format
this can play havock with PC's, The Program Name that i have is 
HYPFM320.PRG, i don't know if there is a later one, also this Program
will do 1.1 Meg and 1.2 meg Formats, with Hardware Mods, this i don't
have the details on, but from what i gather, you speed up the clock
to the controller ic..

I don't know about this one, but I posted my formatter to
comp.[sources binaries].atari.st, which formats 10 track, 80 sector
disks and verifies them.  It runs as a program or accessory, and
writes 800K disks such that single sided drives can read 400K of that.

It's called DUBL_VIS.PRG and it should be on the archives, I suspect.
It doesn't have any interesting options like ms-dos boot sector or
sector skewing, but someone could add that if they liked...

It doesn't do any weird tricks and has been completely reliable in my
experience.

HYPERFORMAT indeed does all these things, but it's not PD. It's part
of my book 'Scheibenkleister', therefore it can only be obtained
legally by buying the book. Just to put in a grain of salt 8-)

You're right with your theory concerning the hardware mod for 1.1 MB
disks. It was published last year in the German computer magazine
'ST-Computer'. In late summer 89, a friend of ours developped the
High Density solution for the ST (1.44 MB, PC-compatible disks),
and HYPERFORMAT supports these formats, too. It packs up to 21 sectors
on one track, totalling a whopping 1.7 MB on a standard 3.5" HD disk.
In Germany, several other PD programs are available that do extra
stuff with your disks; most of them also include some kind of
twister format.

Well, at the moment I have about half a dozen disks that I use daily that are
double sided, 84 tracks and 11 sector - gives me about 930 Kb.  I've been using
them for about 8 months now with no problem - BUT I do use high quality BRANDED
disks (mainly TDK and Sony), lesser quality disks just do not cope.  Anything
past 10 sectors is risky, and to find out how many tracks your drive can cope
with you can (though not really recommended) tell it to format 85 tracks and
listen to the drive - when it stops going clunk after every track then you've
gone to far (ie you can format to one track less than the one you're on).

MOST drives will happily cope with 82 track/10 sectors...

Thank you for giving us more information, sorry did not know that it was
not PD. Please I would like your help on another matter, I have been
having Problems in getting in touch with ST-Computer, I don't think the
First Address that I had was correct, I was after the info, on the
Article on 'Patch as Patch Can', Six Patches for the Bugs in TOS 1.4,
do you know what issue this was in. ??, the Address than I know have is
ST-Computer, Heim Verlag, Heidelberger Lanstr. 194, D-61 Darmstadt,
Gemany, Is this correct..?? Thank you...

Whether or not you can use 11 SPT is not up to the quality of the disk but the
speed of the drive doing the writing. The slower a drive is, the more chance
you have of using 11 SPT. A faster drive will screw up the data though.
Using beyond 80 tracks is dangerous. I know from bitter experience because
using 82 tracks trashed my drive years ago and I had to replace it.
If you use beyond 80 tracks and it works with your drive, fine BUT I don't
think it would be fair to give your disk to someone else and trash their drive.
The use of disks formatted this way is forbidden in our ST lab for just such
a reason.

The maximum sensible format is 80T, 10SPT, 3SPF.

I did write to a Address in Eschborn and enclosed 3 Iternational reply
coupons, with also a PostFach No. obtained from the German Embassy 
here in Wellington New Zealand, but did not get a reply, well I don't
know what to do now, I will try your Address, and see if that works
Thank you, and a Merry Xmas to you...
