Hence, the file is 2 KiB too long, padded with 00. So is that being done by the HDX transfer? I had determined that I am going to have to pull the SD card from my SCSI2SD, so I should have an image to review sometime this weekend.

+mizapf Posted January 14, 2022 Share Posted January 14, 2022 I just backed up a SSSD disk from DSK2 to a floppy disk on DSK1, and as a result I get a file with 361 sectors. 1 Quote Link to comment Share on other sites More sharing options...

+mizapf Posted January 15, 2022 Share Posted January 15, 2022 I loaded the SSSD disk into DSK2 (named "DISK01_1") and put the "meinedisk.dsk" into DSK1. Then I ran DSKBACKUP and selected "backup" from DSK2 to DSK1. (All done in MAME, of course.) Quote Link to comment Share on other sites More sharing options...

It is the creation of a disk image which is giving errant results. e.g. source DSK1 to SCS2.DSKIMAGE.TILES99 The TILES99 file created is 2k too long, padded with >00. I can restore from the image to a formatted disk without issue. Quote Link to comment Share on other sites More sharing options...
+mizapf Posted January 15, 2022 Share Posted January 15, 2022 And when you copy that image file to a floppy disk? I noticed that the 368 sectors on the IDE drive turned to 361 on the floppy drive after I copied it with DM2K. The reason for that is supposedly the AU size of the IDE drive (you can only allocate multiples of 8 sectors). Edit: I have some problems copying a disk to the SCSI drive; after the first 24 sectors are copied (seems to be one pass), I always get a "image error 6". As you obviously succeeded here, I'll have to do some bug hunting. Quote Link to comment Share on other sites More sharing options...

But I ruled that to being a problem with my SD card as it tends to happen irrespective of what program I am using. I should be able to give more details on the process tomorrow as I can make it into the office. Quote Link to comment Share on other sites More sharing options...
+OLD CS1 Posted January 15, 2022 Author Share Posted January 15, 2022 Here is the image file when created from DSK1 to SCS2, file size is 368. And the image file after being copied to DSK1, file size is 369. The rest of the process is in the previous Zip file. Quote Link to comment Share on other sites More sharing options...
+mizapf Posted January 16, 2022 Share Posted January 16, 2022 Hmm, right now I can only check this in MAME with an IDE drive; SCSI reproducibly gives me Image error 6. I just tried it again - when I dump DSK2 on IDE1, I get a 368 sector file, and when I copy it with DM2K to DSK1, the resulting file has 361 sectors. ? 1 1 Quote Link to comment Share on other sites More sharing options...
+Schmitzi Posted January 18, 2022 Share Posted January 18, 2022 This is what Wolfgang answered. See my translation below: - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - DiskBackup erstellt am TI eine exakte Kopie des Inhalts einer Diskette im DF128 Format. Damit entsteht bei einer SSSD Diskette eine 90kB große Datei mit 360 belegten Sektoren. Da diese Datei ja am TI auch eine FDR hat und dieser mitgezählt wird, zeigt sie ein Diskmanager mit 361 belegten Sektoren an. Wird eine solche Datei auf den PC übertragen, weiß das übertragende Programm nichts davon, daß es sich um ein Disk Image handelt und setzt einen TIFILES Header mit TI Namen und Format davor. Am PC sind die Datenblöcke einer Datei 1kB groß. Damit entsteht dort ein 91kB große Datei. Man sollte also bei der Übertragung auf den PC darauf achten, daß nur die reine Daten ohne Header übertragen werden. Der MFM hat im Setup eine Option dafür. Bei anderen Programmen weiß ich leider nicht, ob und wie das geht. Bei der Rückübertragung auf den TI kommt ein Image, egal, ob mit oder ohne TIFILES Header mit 361 Sektoren an und sollte dann vom DiskBackup auch wieder sauber auf eine Disk geschrieben werden. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - DiskBackup 2.1 creates an exact copy (image) of a floppy disks´ content in DF128 format on the TI-99. For instance, with a SSDD floppy disk, a file of 90KB with 360 filled sectors is created. Because this file also uses a counted (extra) FDR, DiskManagers will show 361 used sectors. If you transfer this image-file to the PC now, the transferring tools does not know about this circumstance (that it is an image-file) and adds the TIFILES header with TI Name and Format. Data blocks on PC are of 1 KB size, so on the PC you will have a file with 911 KB as result. Due to this, you should pay attention *not* to transfer the header, just data only. The MFM (Magic File Manipulator) has this as an option. For other tools, I do not know about. If you transfer such an image file - with or without header - back to the TI-99, it has 361 sectors there and the DiskBackup 2.1-Tool will safely write it back to a floppy disk. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Quote Link to comment Share on other sites More sharing options...
+mizapf Posted January 18, 2022 Share Posted January 18, 2022 Unfortunately, this does not seem to be the actual problem; I also got a similar answer. Wolfgang is currently looking for his sources of the latest DiskBackup to send me a copy. 1 Quote Link to comment Share on other sites More sharing options...
+dhe Posted January 18, 2022 Share Posted January 18, 2022 @mizapf I agree with the statement: "We could need a proper name for that. " As you know, this started out with XMODEM needing a way to place files on a BBS and then get them back properly. Then it expanded to whole diskettes pc99, v9t9, etc. Since you have already done a great deal of leg work with chadman and TI Image Tool I hope you will consider creating a new thread of the various format that you know about, that others folks can added to and enhance when things come up.

+mizapf Posted January 18, 2022 Share Posted January 18, 2022 Giving formats a name is not so easy if your name is not IETF, ISO, DIN or whatever. I suggested things like that in the past now and then, and it shows that people tend to stick to the familiar naming after all. Quote Link to comment Share on other sites More sharing options...
