Package: Hurd Severity: normal I have tried to install July 2020 version of Hurd on a real (Dual Core 3 Ghz) computer.  AHCI was not working (with a message Phy0? from memory).  So I change in the BIOS, AHCI to IDE.    Then the 500 GB disk was detected as:  hd2: ST500DM002-1BD142, 131071 MB CHS=16709/255/63    I booted a Puppy Linux on it, and in Gparted,  CHS=60801/255/63
