I have only ever seen this issue in cases where people were using CloneZilla. > CCing John as he is the original atari patch author > > @john: I am heavily suspecting here the disk signature, but maybe you > have a better idea ? You can just backport this patch that upstream has to workaround this problem [1]. Basically, they just changed the order in which partitions are probed and thus, parted probes for MS-DOS first, then later for Atari. I hope I'll find some time in the near future to properly investigate this issue though. The idea is to have a look at how the kernel does the Atari partition probing, the code there seems more reliable.

Bug#896171: MS DOS partition table recognized as Atari AHDI
Ok i can reproduce the issue using the pc6.mbr posted by bouke: cp pc6.mbr disk.img # otherwise parted complains "Can't have a partition outside the disk" truncate -s 600GB disk.img # fdisk correctly detects the msdos partition table fdisk -l disk.img Disk disk.img: 600 GiB, 644245094400 bytes, 1258291200 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x44a777ed Device Boot Start End Sectors Size Id Type disk.img1 * 2048718847716800 350M 17 Hidd disk.img2 718848 975747071 975028224 465G 7 HPFS disk.img3 975747072 976771071 1024000 500M 27 Hidd # parted fails parted disk.img print Disk /home/manu/Téléchargements/disk.img: 644GB Sector size (logical/physical): 512B/512B Partition Table: atari Disk Flags: Number Start End SizeType File system Flags 1 8323MB 14,8GB 6446MB primary boot Also using the disktype utility (which knows both msdos and ahdi) the msdos partition table is properly recognized. CCing John as he is the original atari patch author @john: I am heavily suspecting here the disk signature, but maybe you have a better idea ?
