I guess that for some people is easier to criticize, find errors instead to follow really simple instructions. Why I think so ? Really, you needed weeks to find "(I just tied it I can just modify the sector count" . So excuse me, but this is just too annoying. You say that you appreciate, but all your responses just bring new critic and new questions, even about what is already explained.
So, yes, my instructions are not good, my English is not good - I would say only for people like you, who can't write some value in standard Windows dialog edit box .
OK, that was my reaction part, and you should really think about yourself a bit. Because it is really not so hard to use program. Actually, I did not get so many questions over 10 years as only from you in last 1 month,
This program is like all my utilities what I programmed for Atari ST and Windows, Linux: you will see not buttons, some 'wizards' to perform some concrete action like making image of attached Flash card, and then it will lead you step by step in that process. My approach is 'control panel' like - user needs to set certain fields and then press some action button. Surely, it requires some knowledge about computers, storage, but it is just faster and is more flexible.
Program is made with concrete purpose: to help retro computing, to help usage of in that time (2006 ...) relative new Flash cards. Extra support is added for 2 retros which I used and did some HW, SW for: Sinclair Spectrum and Atari ST serial. I made first IDE adapter for Atari ST in 1992 and used it first with some 40 MB Seagate disk. Little later made IDE adapter for Spectrum, what was much harder (because 8-bit bus) . I bought in those years diverse used hard disks of capacity between 60 and 160 MB. Some died after short usage, some are still working. And that was era of CHS hard disks. LBA came later. It is easy to look after those abbrevs, to look historical development of IDE disks. Not for all indeed - some like more to write new manual - please don't do that, results will be catastrophic and embarrassing for you. I mean this is absurdest thing I seen here, really. You lack totally basic knowledge.
So in short: early hard disks used CHS addressing - like floppy drives. To access some concrete sector on disk you need to give cylinder #, head # and sector # . That requires extra calculations in SW. Easier is linear addressing - for user, not for hard disk's controller. But as capacities grown, CHS became limited. I don't even remember at moment what was actual limit - 128 or 512 MB (not talking about BIOS limits of PC motherboards) with CHS. Or maybe 2GB .. totally forgot it So, they introduced LBA addressing, which was btw. used by SCSI already. First LBA was with 28-bit sector addressing, therefore max supported capacity was 128GB - pretty much for year 1995 for instance. About 2005 it became too little, so we have now LBA 48 too - you are free to calculate what max capacity it can address
All in all, CHS is there only because historical reasons. And RAW images will not save any CHS info. Only HDF format supports it - what is not needed for modern storage. I even removed CHS support from my later hard disk drivers, because nobody uses those old hard disks now - if there are some working ones still (I have couple, but use only with Spectrum - once in 5 years) .. Btw. you will get absurd values in CHS for any modern storage with larger capacity (GBs) - way too big cylinder values. Probably should just write there lines in such case. And of course HDF format can not even hold so large cyl. values.
There is no explicit button/option for drive backup . My opinion is that if someone can not get what those few buttons are for, better don't use this program. Because it is very dangerous. You can kill your Windows very easily by mistake.
First problem is to recognize which detected drive in list at left is what.
To finish this long reply only one thing more:
There is section in help file, in WEB page "Atari ST GemDos, DOS16 & BigDOS file transfer & partition extract"
Quote from it: "Sunken button 'Partitions:' is for extracting image file of only selected partition. From drive or image file. In case of swapped L/H it will be saved in normal order, so may access partition with common tools. It also sets 'Sectors from start' and 'Sector count' to position of selected partition in main window (just close file selector without save). So advanced user may insert partiton with new content in disk or image file. It is dangerous operation, so do it only if know what are you doing."
And yet, you used CHS. Additionally, you wanted to save only first partition, some 2GB. Why would be easier to mess with CHS calculation instead using simple math and convert 2GB to sector count ?
I gave you answers to your questions, gave you some tips how to make it easier, and what I see is not "thank you", but some silly talk about confusing instructions. Yes, they are confusing for you, because your approach is totally wrong.
