DOS疑难解答 & 问题讨论（解答室） » Software for partitioning 2T hard drives in DOS

Recently bought a 2T hard drive. When partitioning under DOS, it cannot be recognized. (Used dm9.57, fdisk, gdsk, gdisk, sofdisk, pqmagic, etc.) In a last resort, I partitioned it under Windows. But when booting, the 2T hard drive can boot alone, and the 250G hard drive cannot be used as a slave drive. Only when the BIOS is set to PATA mode can the 250G hard drive be recognized. Currently, can large hard drives not be partitioned under DOS? Is there a DOS large hard drive partitioning software? Attachments f32.gif (17.37 KiB) 02.gif (15.06 KiB)

gdisk should support up to 2TB, but still can't recognize?

There is the same problem, the 1T one just doesn't work.

It is estimated that this has little to do with DOS, but is due to the BIOS's hard disk addressing. MS-DOS 7.1 supports a maximum capacity of 2TB per hard disk (it is a full TB, not the 10^12 bytes of hard disk manufacturers)

For motherboard issues, then you can only partition in PE or Windows.

I also encountered this situation. I couldn't use the disk management in PE to partition. But I couldn't boot finally. In the end, I rewrote the MBR with WinPM, and then I could boot.
