576XE Posted January 15, 2022 Share Posted January 15, 2022 (edited) Hello Dear Atarians! Recently I've tried to create new Atari environment in Altirra 4.0 (4.10). I used FDISK from SDX4.49. And YES, Writeprotecting checkmarks are cleared both from IDE+2 settings as well as HD disk settings! 1. FAT16 (16 MiB) - good. 2. APT SDX (32 MiB) - good. 3. 4. - Can not be formatted... Your suggestions are very appreciated!!! zen Edited January 15, 2022 by 576XE Quote Link to comment Share on other sites More sharing options...

576XE Posted January 15, 2022 Author Share Posted January 15, 2022 Hello sup8pdct! This 'magic 65534 sectors' works both in 'Black Box HD Utilities Disk' (Thousand THANKS) and in MyDOS native environment too. Best wishes from iced and Snowed Moscow !!! zen 1 Quote Link to comment Share on other sites More sharing options...

My guess is that not enough buffers have been declared to handle more than drives D1: and D2: (yup, it is not SpartaDOS, which handles this automatically).

576XE Posted January 15, 2022 Author Share Posted January 15, 2022 Hi Drac030, Hi Konrad Really it's only 65534 error. As you may know the filesystem in MyDOS and TopDOS Pro is almost the same. (Toms Navigator reads TopDOS HD DIRs) Bennet and Marslett have a good contacts in time. I know that TopDOS is VERY sensitive to buffers amount and is not silent while error occures. I've successfully created and initialized TopDOS Pro partition (first preparing it in MyDOS as 65534 sectors). TopDOS uses magic 8192 number but 65535... I think it's simply miscalculating of sectors quantity between FDISK and 'I'-command from My / Top doses. Case for honored MAD-team friends... Warmest wishes from Moscow. zen Quote Link to comment Share on other sites More sharing options...

576XE Posted January 16, 2022 Author Share Posted January 16, 2022 (edited) Hi Stephen. Wombats are used to it. More skunk, less skunk no mean... All around die quickly and painlessly... Where the problem? And when I play on 'Wobbleboard' I hope that their rectangular anus became slightly rounded and more circular... Talking about australian mammals I can say that it's a good habit to find a bottle of beer in your 'pocket' even in the middle of the desert. Just having a 'poket' you are decide a half of problem! Beavers in contrary opens every bottle momentarily whith their teeth. Worlds Harmony! zen Edited January 16, 2022 by 576XE Quote Link to comment Share on other sites More sharing options...

576XE Posted January 20, 2022 Author Share Posted January 20, 2022 Hello Friends! Yesterday I've created normal HD environment (Magic number was standard = 65535). It's a good news! Bad news I don't know how I did it at all !!! I just launch Altirra 4.0 with Administrative privileges. I beleive that it's Win10 jokes with Atari emulators. We all awaiting Win11 orders ... The way took 2 weeks because of different sporadic errors... (No drive, Time out etc.) zen Quote Link to comment Share on other sites More sharing options...
flashjazzcat Posted January 20, 2022 Share Posted January 20, 2022 The magic number is 65535 because that's the highest value which can be represented by 16 bits ($FFFF), and the Atari SIO subsystem uses a 16-bit sector addressing system. 1 Quote Link to comment Share on other sites More sharing options...
576XE Posted January 21, 2022 Author Share Posted January 21, 2022 Hello, FJC! Thank you for reply. Glad to hear from you! I named this number 'magic' because 'Black Box HD Utilities Disk' uses 65534 instead .?! I know that counted number of Atari address field is 65536, and index to addresses is 0-65535. By the way TopDOS Pro added byte to 'counter of files in directory' and they say that DD based densities can contain 256 files/dir if the modifier /D in format string added !!! zen Quote Link to comment Share on other sites More sharing options...

Logical sectors on the Atari are customarily numbered from 1, so a partition whose last sector number is $FFFF commonly has 65,535 sectors. I don't know if BB deviates from this, however (perhaps partitions include logical sector 0 for some reason, even though DOS will never write to it). This is why specifying 65,536 ($10000, exactly 32MB) as the partition size in FDISK will make the partition unusable with SDFS, MYDOS, etc; any file system using 16-bit cluster addressing will see $0000 clusters. SDX is capable of observing the upper bits of the size reported by the PERCOM block, however, and - via the 'XDCB' (32-bit block addressing extension used by IDE Plus, U1MB/SIDE, etc) - can address very large (>32MB) partitions using a suitable file system (e.g. FAT16, which still uses 16-bit cluster numbers, but is capable of 28-bit LBA sector addressing).

576XE Posted January 30, 2022 Author Share Posted January 30, 2022 Hello, Friends! Now I have two messages: 1. To achive some success with Altirra/IDE+2.0 I just launch Altirra as Administrator and Voila ! It's simple. 2. And this is much more serious !!! PreHistory: - Some truly advanced zoologists here carefully explored specific shapes of a.m. mammals I/O-connectors and particular penetration methods to achive their internals... BUT! Please, look at the picture... - Evidently you can see here that left kiba-dachi mammal very poor protected from front/rear attacks being mightily protected from side-directed attempts. - And look, please, at right participant, particularly on it's teeth, katana-sharped biver tail and it's (tail's I mean) exact position. (I've never see anywhere a sword between own legs!) - This Samurai is Hard as Rock, Cool as Sea, Accurate as Chronometer, Powerful as Tornado, what's more?.. Attack? - No chance! i.e. You are observe here NEW clearwater strategy/tactics method effectively protective against highly skilled and deeply motivated gatecrash-oriented zoologists. zen Quote Link to comment Share on other sites More sharing options...
