Could someone give me a short leasson in 1581 usage?
Could someone give me a short leasson in 1581 usage?
I would like to know how to create partitions/subdirs and how to go to such a directory. I need it for making a test .D81 file for possible PRG Starter .D81 support.

You should download a copy of the 1581 user's guide from here and direct your attention to page 77 where you'll find information about partitions and sub-directories.Boray wrote:I would like to know how to create partitions/subdirs and how to go to such a directory.
In the end it will be as if nothing ever happened.

If you have a C64 or C128, you can use 1581 Toolkit, and that program will easily make partitions on a 1581 disk.Boray wrote:I would like to know how to create partitions/subdirs and how to go to such a directory.

I tried this in VICE but nothing happens:
10 open15,8,15
20 print#15,"/0:subdir,"+chr$(80)+chr$(0)+chr$(240)+chr$(0)+",c"
30 close15
Nothing shows up in the root dir. Is something wrong or isn't subdirs supported in VICE or .D81 files?

I managed to test partitions by using the Bible.D81 to try with... I've concluded that VICE doesn't look inside the partitions when autostarting so I don't have to bother with that either.

I'm just starting to play with Partitions... There are only 80 tracks, and 40 sectors per track but in your example above you start the partition at track 80 and try to allocate 240 sectors, which goes beyond the capacity of the disk. Make sure you select the 1581 as your drive type in Vice.Boray wrote:Thanks!

I am able to create partitions using vice that appear in the directory, but so far am not able to get into those partitions to format them or store files on. I've created up to 4 partitions of verious lengths but when I try to select them I get error "77, selected partition illegal"....
Anyone else have any experience with these without using a utility?

The 1581 has 80 tracks with 40 sectors each, 3200 blocks total. 40 blocks are required for the directory track, which gives 3160 blocks free on an empty 3 1/2 inch disk.
For the two Bible disks I created the partitions (which contain the chapter files as SEQ data) manually. I used no other method than the one described in the 1581 manual, so there ...sjgray wrote:Anyone else have any experience with these without using a utility?
So my original reply is correct then? The OP was trying to create a partition that would spill off the end of the disk. Specifying a lower start track would be the answer.
It still doesn't explain why I can't get into my partitions. The user's guide says the ending sector must be a multiple of 40, but if sectors start at zero then 39 is the last sector. I've tried xx=39,40,80 etc as my "number of sectors" in the "/0:name,tsxx,c" create partition command, and still I can't get into it.
I'm looking for a D81 image that contains multiple partitions, formatted with files. Can anyone help?

Hi, Steve,
For a 120 blocks partition at the start of the disk (the minimum size which can be formatted), you'd specify:
then change into that partition, and format it with the same ID that was used for the whole disk.

In these two threads you find example *.d81 images:I'm looking for a D81 image that contains multiple partitions, formatted with files.
