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

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

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. > > ....Thanks ahead of time... .....Yonderboy@cup.portal.com ---jb

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.

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. -sam

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. ---------------------------------------------------------------------- Claus Brod, Am Felsenkeller 2, Things.

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. +----------------------------------------------------------------------------+ !
