Re: [PLUG] fdisk partition problem
|
I am not sure what happenned but it appears that the disks c/h/s did
change and the partitions, as I wanted, were there once I rebooted.
I susccessfully mounted and backed up my primary drives partitiions to
identical partitions on the backup drive.
I guess the fdisk change of heads and cylinders worked and it just needed
a reboot - which I guess you should do anyhow when you fdisk.
