Il mio nuovo portatile me lo hanno dato con una tabella delle partizioni che a fdisk non piace molto:

Codice: Seleziona tutto

root@matteo:/home/matteo/DELL# echo -e "p\nx\np"|fdisk /dev/sda

The device presents a logical sector size that is smaller than
the physical sector size. Aligning to a physical sector (or optimal
I/O) size boundary is recommended, or performance may be impacted.

Command (m for help): 
Disk /dev/sda: 750.2 GB, 750156374016 bytes
255 heads, 63 sectors/track, 91201 cylinders, total 1465149168 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes

Sto per rimuovere le prime due partizioni (sda1 e sda2). Poi che ottimizzazioni posso fare?
