Image format

HDI

Application that created the image

NHC for Linux Ver.0 alpha49 2021/10/03; MAME v0.238

What were you doing when it failed?

  • I was converting the image to another format...
  • I was retrieving image information...
  • I was retrieving filesystem information...
  • I was listing the filesystem contents...
  • I was extracting the filesystem contents...
  • I was creating a metadata sidecar...
  • I was checksumming the image...
  • I was verifying the image...
  • I was calculating the image entropy...

Destination image format

No response

Filesystem

FAT12

Description

Created this blank HDI image with NHC, formatted it in MAME's PC-9801RS driver using MS-DOS 6.22 (mame pc9801rs -hard1 test.hdi -flop1 msdos62:flop1). Removing the 0x1000-long header gives a raw image that parted can identify properly:

Model:  (file)
Disk /home/logan/download_rom/pc98/test.img: 51609600B
Sector size (logical/physical): 512B/512B
Partition Table: pc98
Disk Flags: 

Number  Start   End        Size       File system  Name         Flags
 1      65536B  39387135B  39321600B               MS-DOS 6.20  boot

However, unlike other .HDI images (presumably made in other emulators), attempting to list the files on the image in aaru led to failure.

Exact command line used

aaru i info test.hdi

Expected behavior

Similar output to a supported HDI image

Originally created by @einstein95 on GitHub (Dec 13, 2021). Originally assigned to: @claunia on GitHub. ### Version 5.3.0 ### Commit hash _No response_ ### Tested debug version? - [X] Yes ### Which operating systems have you used? - [ ] Windows - [X] Linux - [ ] macOS - [ ] Other ### What is the architectural bit size you're using? - [ ] 32-bit - [X] 64-bit - [ ] Unsure or unknown ### What processor are you using? - [X] An Intel or AMD - [ ] An ARM or Apple Silicon - [ ] Unsure or unknown ### Image format HDI ### Application that created the image NHC for Linux Ver.0 alpha49 2021/10/03; MAME v0.238 ### What were you doing when it failed? - [ ] I was converting the image to another format... - [ ] I was retrieving image information... - [X] I was retrieving filesystem information... - [ ] I was listing the filesystem contents... - [ ] I was extracting the filesystem contents... - [ ] I was creating a metadata sidecar... - [ ] I was checksumming the image... - [ ] I was verifying the image... - [ ] I was calculating the image entropy... ### Destination image format _No response_ ### Filesystem FAT12 ### Description Created this blank HDI image with NHC, formatted it in MAME's PC-9801RS driver using MS-DOS 6.22 (`mame pc9801rs -hard1 test.hdi -flop1 msdos62:flop1`). Removing the 0x1000-long header gives a raw image that `parted` can identify properly: ``` Model: (file) Disk /home/logan/download_rom/pc98/test.img: 51609600B Sector size (logical/physical): 512B/512B Partition Table: pc98 Disk Flags: Number Start End Size File system Name Flags 1 65536B 39387135B 39321600B MS-DOS 6.20 boot ``` However, unlike other .HDI images (presumably made in other emulators), attempting to list the files on the image in aaru led to failure. ### Exact command line used aaru i info test.hdi ### Expected behavior Similar output to a supported HDI image ``` Image format identified by Anex86 Disk Image. 1 partitions found.

@claunia commented on GitHub (Feb 7, 2022):

The image is incorrect.

It indicates it has an HDD of 100 cylinders, 16 heads and 63 sectors per track.

However the partition indicates an HDD of at least 600 cylinders (with that HDD size it would indicate 17 sectors per track and 8 heads), with the DOS partition indeed found at byte offset 73728 (4096 + 1cyl = 4096 + 1178*512 = 4096 + 69632 = 73728).

Please open a bug report to MAME so they can correct their HDI implementation.

Parted, not knowing the size of a cylinder, is making the same assumptions and you can see it's telling you incorrect values (that the partition is half the size it really is, as 600 cylinders 8 heads 17 sectors would be 41779200 bytes.

If you want to manually fix the image with Aaru, take the latest commit and use the following command line:
aaru.dll i convert -g 600/8/17 test.hdi test.aif

Then it works:
