1571 H1 format fails with empty .g71 #340

Open Jusalak opened 1 year ago

Jusalak commented 1 year ago

When an empty .g71 image is created with F5 > Create, and then sides are formatted separately with 1571

OPEN15,8,15,"U0>M0":CLOSE15 OPEN15,8,15,"U0>H0":CLOSE15 OPEN15,8,15,"N0:SIDE1,01":CLOSE15

OPEN15,8,15,"U0>H1":CLOSE15 OPEN15,8,15,"N0:SIDE2,02":CLOSE15 The drive gets stuck on side2 (H1).

But when using a .g71 pre-prepared with Z64K emulator (one is attached in thread (".D71/.G71 disk image with 1541"), then formatting of side2 proceeds fine.

radius75 commented 1 year ago

I can confirm it. D71 and G71 created with Ultimate and also created in Vice have an error when formatting with this program in U2+ 1571format.zip

As mentioned in https://github.com/GideonZ/1541ultimate/issues/324#issuecomment-1519130298 , .d71 is not compatible to U0>H1 from its design, so it cannot work.

The back side of a standard 1571 disk has track 36 to 70 in its header, bur for "U0>h1" the back side has headers with track 1 to 35. Since the d81 format has to way of storing the sector headers, that difference cannot be included in the d71 image.

But g71 should have worked...

radius75 commented 1 year ago

I checked G71 and D71 created in Ultimate can be formatted in Vice with this prg. Both can switch H0 and H1 on Vice and read directories. Probably d71 is damaged as you wrote. On U2+, from these formatted floppy disks only g64 can read the directory $, U0>H1.

radius75 commented 1 year ago

@markusC64 Out of curiosity, I saved two demos on Vice to d71: Side H0 - Coma Light 13 side1. Side H1 - Uncensored side1. And both work until prompted to change the floppy. Vice in the 1571 emulation. They save the catalog on track 18 (H0), and 53 (H1). d71.zip For copying, I just use ActionReplay.crt obraz obraz

Side H1 / TR18 SE00 Everything seems to be as it should be obraz

Jusalak commented 1 year ago

With this blank .g71 from Z64K emulator the H1 formatting proceeds normally, but on ejecting the disk the message "not all tracks were saved" appears and a prompt to save with another filename.

blank.zip

Jusalak commented 1 year ago

Conversely, I tried formatting (as described in the beginning) an empty .g71 generated by U64, in Z64K emulator. From the standpoint of Z64K, the .g71 image seems perfectly valid, behaving in the same way as formatting (again in the aforementioned manner) a Z64K-generated .g71 image. After formatting both files were saved; they then had the same size (556 456 bytes), but their contents were different.

VICE had the same result: U64-generated .g71 is valid, but this time file sizes were different: after formatting, U64-generated file had size of 506 480 bytes, VICE-generated file 667 476 bytes.

And I also confirm that when formatting VICE-generated .g71 in U64 the drive gets stuck (but, as mentioned above, with Z64K-generated did not).
