Hello List mates,
I recently purchased a Western Digital "Black" 500 GB drive with 7200 rpm.
When I create partitions during the install using the "optimal" option, the following appears when I select fdisk.
fdisk -l

Why is 1st partition's last cylinder sharing the same number with the 2nd partition's first cylinder when the gui showed the 2nd partition starting on the next cylinder?
Cylinders are calculated from sectors and different sectors can map to the same cylinder. Look at the partition table in sectors and everything will be fine (no overlap). ciao Arvin -- Arvin Schnell, <aschnell@suse.de> Senior Software Engineer, Research & Development SUSE LINUX Products GmbH, GF: Jeff Hawn, Jennifer Guild, Felix Imendörffer, HRB 16746 (AG Nürnberg) Maxfeldstraße 5 90409 Nürnberg Germany -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
