ROMidsq, SMSQ/E v3.31
Reading and writing a DD disk FAILs

B) Machine 2
= Aurora + SGC + ED drive + QUBIDE, SMSQ/E v3.31

Hi Bob,


This problem also exists on the HD drive of my Aurora or QXL-PC.
If I can find a working DD drive I may test this later.



Again just to be clear : yo also cannot read/write/format disks when  
they are HD (1.4 MiB) disks, when using he Aurora. Does this need a  
GOldcard or Supergoldcard (and if so, which do you use?).



Just to add some clarity I did some testing.

A) Machine 1 = QL(i6)+SGC +ED +HD drives, SMSQ/E v3.13 booting from  
ROMdisq.

Reading and writing a DD disk was OK on both ED & HD!
When I replaced the HD with a DD drive reading & writing was also OK.

B) Machine 2 = Aurora +SGC +ED drive, SMSQ/E v3.21 booting from Qubide  
disk.

Reading DD disk OK, writing hangs the system, hardware reset needed!
When I replaced the ED with a DD drive reading was OK, writing hangs.
No null length files were opened on the DD medium.
Also reading an msdos DD was OK but writing hangs again.
On this Aurora under QDOS, reading & writing a DD disk was not a problem.
Repeating this test with SMSQ/E v2.91 confirmed DD was OK there.

C) Machine 3 = msdos 7, QXL plus HD drive, with SMSQ/E v3.21.
Reading and writing a DD disk was OK!
My earlier claim that QXL also gave problems was based on older PC  
hardware which is no longer functioning and may have been a faulty disks.


All testing was done with QPAC2 Files using the Backup and View options  
and performed on the same disk.
I no longer have a GoldCard to compare with but these tests seem to  
suggest an Aurora/SMSQ conflict. Both SGC's report a v2.49 ROM.


Reading and writing ED or HD disks may give occasional problems which I  
suspect are individual disk faults and usually only report medium errors.
I have not done any formatting tests but problems on Aurora in the past  
made me adopt the practice of always doing this under QDOS, the whole box  
of 10 in one go.


I hope this helps,
Bob

I was just guessing, because it theory there could have been some 
implicit byteswapping on the QL Qubide driver or hardware side, 
making up for CPU endianess.

Re: [Ql-Users] QxlwinReader

2017-06-21 Thread John Impellizzeri via Ql-Users
Hi all,

I’ve been following this thread with some interest as I still have some QL 
hardware (SGC/Qubide/Aurora) which I recently converted from a spinning IDE 
hard drive to a Compact Flash card using an adapter.  I then added an 
additional adapter with an external slot to use as a backup medium.

As a further backup I moved the backup CF card to a Mac with a card reader and 
used dd to make an image file of the card.  By writing the image back to 
another card with dd and verifying that the QL could still read it I knew that 
this process was successful.

When I read about QXLwinreader I was interested as I’d like to start playing 
with the various emulators again but moving software to them from my real QL 
via floppies wasn’t sounding like much fun.

I tried QXLwinreader on my dd image but it was not recognized as a valid image 
file.  Then I read the post about the file possibly needing conversion due to 
the 68K being big-endian.  Since I was running QXLwinreader on a Mac with an 
Intel cpu (little-endian) I ran dd on the file again using the conv=swab option 
and I can report that QXLwinreader happily accepts the converted file and I can 
peruse through files and directories in it.  I haven’t tried copying any files 
yet in either direction as I have to set up a QXLwin file yet but it looks 
promising now.

For reference the converison process was quick only taking seconds on my 7 year 
old Mac.  One image file was 512MB and the other was 1GB.

Here was the command I used:  dd if= of= 
conv=swab

As for the floppy format problem I have a Gold Card here somewhere, I will try 
to find it and hope it still works and do some testing with it.

I can confirm that my SuperGold Card system with Aurora running recent SMSQ/E 
versions does have some trouble formatting floppies although I’m pretty sure I 
can format HD but not ED disks in ED drives.  I’ll have to test again with DD 
disks as I don’t remember if I tried this.  I can read an existing ED disk, not 
sure if I can write to one.  I know I have been able to read and write to DD 
and HD disks.

The format command does seem to cause the drive to make some strange sounds at 
first before settling in to the normal stepping routine as it formats the disk.

If it were possible, it would be nice that with QXL, you should not have

configurable as with QPC in any subdirectories

This can be simulated on the PC side in the AUTOEXEC.BAT with a DOS  
command like SUBST: e.g. SUBST X: D:\qxl\data
This way you can point win2 to drive 'X' and put your QXL.win inside the

For 'X' you can use characters that do not upset anything on the PC side.

Hi Davide,


... The DD Unix utility might
be of course an interesting option but maybe it could be more useful for SD
cards written with the QL-SD interface rather than a Qubide hard disk
(especially if it has more than one partition)


Whilst it's true that this was written with these cards in mind, I'm not 
sure about this statement. If you have a PC that still has the 
connections for your hard disk (I presume it's IDE ?), using DD (or 
equivalent) might be the fastest way to get your data off that disk.


I think I can confidently state that if I had an image file with several 
partitions, I could probably figure them out pretty quickly and amend 
QxlwinReader so that it can handle them.


Tracks/cylinders/heads would be more difficult.


Talking more in general I think it is a pity that some possibile
implementations or bug fixes are becoming very difficult if not impossible
just because lack of the native hardware to test to the few people which
have the knowledge to solve these issues. I wonder how this could be
improved. 


Yes, not being able to reproduce and trace a bug is a problem. For 
example, some time back, a problem with SMSQ/E for the Atari was 
reported to me. I used to have some Ataris (and still had/have them but 
not in working condition). So there wasn't much I could do, until I 
stumbled upon an Atari emulator for the PC, which at least allowed me to 
see and even test the problem, and eventually figure out what went 
wrong. That was pure dumb luck!


As you rightly point out, without the actual hardware this is going to 
become practically impossible - not only to fix, but even just to check 
whether the problem exists (a case in point : some recent QXL screen 
problem, one user (Andrea) reported a problem, I had a look at the code 
to try to find out why but couldn't, and then another user (Bob) said 
that it worked OK...).


I'm not sure what can be done about this situation. Perhaps your 
solution, to supply actual hardware to people still fixing things might 
work. Without false modesty, I think I can safely say that most recent 
development for SMSQ/E has been done by Marcel, and to a much lesser 
degree, by me. I won't presume to speak for Marcel, so this only goes 
for myself : I'm just not sure that I'd want more hardware here!


Also, don't forget that working on SMSQ/E is purely a voluntary work.
For me, there is a big difference between writing something new like the 
recent Thing, and then fixing the problems I inevitably introduce on the 
one hand, and fixing other bugs, on the other hand.


Since I've become the "regsistrar", which was supposed to be a purely 
administrative job, I'm often being asked to fix problems in some old 
code which I didn't write nor know about. It then takes me a lot of time 
to look at the code to try to understand it. In most cases I then just 
chicken out and refer this to Marcel :-), on some rare occasions, I 
manage to find the problem myself and fix it. For me, this is less fun 
than writing something for myself. I still do it just because I like 
SMSQ/E... But the point is that I do it because I want to, not because 
there is any obligation to.



Finally just a not-so-related question: There is a bug reported here 
that precludes formatting disks on a SuperGoldgard - does anybody know 
whether that is also true for a simple Goldcard? I ask because I know 
that I can get my hands on one of those.

[Ql-Users] QxlwinReader

2017-06-18 Thread Wolf via Ql-Users

Hi Davide,

Just to try and clear up some things about QxlwinReader.

This program reads Qubide image files. These are copies of a whole 
qubide disk, copied to a simple file. I should indeed have mentioned in 
my reply to you that the "dd" program I referred to is a utility that 
comes as standard with Linux and allows you to copy all or part of the 
content of some device to a simple file on another device. As others 
have mentioned, something similar also seems to exist for windows, 
though I have never tried that.


QxlwinReader cannot, and will never be able to, read a disk directly. To 
do that, I would either have to be able to access a real disk for a raw 
read/write which, unless I'm mistaken, java doesn't allow me to do (at 
least not in an OS independent way), or write a filesystem driver: one 
for Linux, and another for Windows, probably yet another for Mac etc - 
you can see why this isn't feasible.


Moreover, please note that QxlwinReader can only handle "LBA" type image 
files, i.e. ones where files are written consecutively to the disk (FAT 
allowing), without taking into account that they should be split up 
between tracks, cylinders and heads. If I had an example of a Qubide 
disk image file actually making use of tracks, cylinders and heads I 
**might** be able to figure this out, too. I believe that Alain Haoui 
has written a driver for these types of disks.


Moreover, for the time being, QxlwinReader only handles the first 
partition of a Qubide disk image file. There is no reason why it 
shouldn't be able to handle the other partitions, too - except that, 
there again, I don't have an example of an image file with several 
partitions, and so would be unable to test this. Knowing myself, letting 
out untested software would not be doing you a favour...

I understand the effort to write such sw might not be negligible, but
a utility which could manage to read native Qubide hard disks on a PC

If you have a PC with IDE port anyway, then where is the problem to use dd
