Re: [Ql-Users] QLTools - 2.15.5 available
Hi, this is the comment I wrote to myself for SMSQmulator in this respect: " Patch for badly constructed drives, like those built by qxltools. These drives do NOT have cluster entries for the FAT(). They just indicate the number of sectors taken by the FAT. I presume that it can then be presumed that the FAT's sectors are all contiguous and start at sector 0. " Treated like this: int nbrOfSectorsInMap=firstSector.getShort(WinDrive.QWA_SCTM)&0x; // that many sectors are supposed to be in the fat int temp=nbrOfSectorsInMap/(firstSector.getShort(WinDrive.QWA_SCTG)&0x); if (nbrOfSectorsInMap % (firstSector.getShort(WinDrive.QWA_SCTG)&0x) !=0) temp++; // these are the number of clusters needed to hold the map if (temp!=this.fatClusterChain.size()) (...) // if they both agree, all is ok, I have a valid drive map HTH Wolfgang Can you give me an example of how to reproduce the problem(s) you are seeing? I've just created a 20 MB qxl.win with no problems. (So far!) Unfortunately not right now, and my memory is vague. I think that all issues were gone with 16 MB and less. My next image size step was probably 32 MB, not just 20 MB. It could be, that just recompiling the latest qxltool source with an up-to-date compiler and library makes the issues disappear. I've created a couple of qxl.win files (at coffee time - I'm working) and checked them with my own QXLWin program. The headers looks strange to me: On the 4 MB I see these dubious fields: * Sectors per map = 21 * Number of maps = 100 * Root directory length = 58 On the 20 MB I see these dubious fields: * Sectors per map = $A1 (161) * Number of maps = 100 * Root directory length = 58 I've had a quick look at the definition of a QLWA header in the code and it appears slightly broken. Some of the fields I would think essential are not being used - sectors per block for example. That changes as the files grow bigger and might be related to your problems. I'll see what I can do - there are still quite a few compilation warnings I need to get rid of first. Cheers, Norm. ___ QL-Users Mailing List

You may want to try a older Version of QPC2 but Some THINGS` work better on the old Version Then the New Version you just see what works Right for you On Saturday, 2 February 2019, 22:18:33 GMT, Norman Dunbar via Ql-Users wrote: Hi Peter.

Hi Peter. One of the reasons I did some work was a recent almost total loss of over 300 floppies going back many years. They had all seized in the cases and refused to rotate. I have "ripped" the ones that still work onto my Linux laptop for posterity. Qltools comes in handy as I cannot get QPC 4.0.5 to read a floppy image. I get not found errors. But I'm running under Wine, which might be contributing. I have qxltools on my laptop but haven't looked at it for ages, I think I had problems compiling it - but I can't remember. It might well be in line for some tittivation! Cheers, Norm.

Re: [Ql-Users] QLTools - 2.15.5 available
Hi, That's quite a changelog! Wolfgang Revision 2.15.5 1) Now compiles under Windows with Gcc. I used CodeBlocks with the built in 32bit gcc to do the builds. There's also a makefile for shell usage. 2) Fixed 32bit bug in formatting an ed image file. It would segfault on Windows 64bit when compiled as 32bit, but not as a 64 bit build. Turned out to be a bug in my 'ed' formatting code. 3) If the image file doesn't exist, it will now be created when formatting an image. 4) Files were being corrupted when extracted from an image with the '-n' option. This was because the 'DOS_LIKE' define was not being done on modern C compilers/operating systems. It is now! The corruption was to add a CR in front of every LF in the file. 5) When changing the dataspace of a file with '-x' the dataspace size was allowed to be an odd size. I'm sure this causes trouble on a QL, so it now gets rounded up if it is odd. 6) The '-M' option to create a level 2 directory wasn't working. This was because it was opening the image file in read only mode. I may have been responsible for breaking this - but don't quote me. It's fixed now. 7) Dumping an ED cluster with the '-u' option (ASCII dump) was only dumping 32 lines of 16 bytes - 512 bytes in total. The number of lines was hard coded. It has been changed to calculate the number of lines from the sector size. This option now works for ED drives as well. 8) Windows uses the '/' character for command line options, unlike Linux which uses '-' and while there was some code that allowed the '/' when 'DOS_LIKE' was defined, it wasn't in all the places it needed to be. Now it is. Windows users have the choice of whichever flag symbol they like. (Well, '-' or '/' is all the choice actually!) 9) Slightly weird. If the '-w' option was used to write a file into an image, and that that file was already there, it didn't prompt to overwrite. I spent ages tracking it down and it turned out that running in a Windows command session does prompt, only running in a bash shell, on Windows, does it not prompt. As most users won't be in my development bash shell, I'm not fixing this. 10) Source Code is available from https://github.com/NormanDunbar/qltools. 11) Compiled binaries for 32/64 bit Windows and Linux are also available from https://github.com/NormanDunbar/qltools/releases - along with a new user guide. If you enjoy using this half as much as I've enjoyed amending it, then I've had twice as much fun as you! :o) Cheers, Norm. ___ QL-Users Mailing List
