Short version: How can one create aligned to the 1MB boundary logical drives in the extended partition, that are still 100% compatible with DOS FDISK? Is it even possible?
The full story: I wanted to experiment with OFORMAT mentioned in this thread but the setup I'm trying to achieve is a primary partition and a logical drive in the extended partition, pretty classic.
So I initially created the partitions using Win10 diskpart, but when I put the SSD back to the old PC, FDISK (of DOS 7.1) couldn't see any logical drive. I thought that the problem was because I created the partitions on a different machine, so I booted GParted directly on the old machine and did the same, with the same results. Photos show what FDISK should display vs what it displays when it doesn't recognize the logical drives, and the actual partitions as they appear in GParted
Now it was the first time I attempted something similar and a brief research, if my conclusions are correct, revealed that the EBRs modern tools create are perfectly fine for Win2000 and forward, but are not what DOS and Win98's FDISK expects (an aligned to 1MB boundaries primary partition is OK, the same for logical drives in the extended partition isn't).
So my question is how can one accomplish this? I imagine that some partitioning tool will be able to align and at the same time write DOS-compatible entries, but I thought to ask here first before I start blindly trying all the different programs.
