IDE disk drivers (`hd*`) however currently do not support more than 2^28 sectors, i.e. 128GiB. The gnumach AHCI disk driver (`sd*`) and rumpkernel drivers (`wd*`) support up to 2^48 sectors, i.e. 128PiB, but the device interface supports only 2^32 sectors, i.e. 2TiB. +To use disks bigger than 128GiB you can either switch your disk to AHCI (BIOS or virtualization) configuration, or switch to [[using the rumpkernel driver|/hurd/rump/rumpdisk]] + You can have a bigger disk, you just should not put disk partitions beyond these limits for the drivers to be able to read from them. |
