I have a new Hard Disk which I want to use for NAS drive. The requirement is that the partition as seen in fdisk should be as below.

Device    Boot      Start         End      Blocks   Id  System
/dev/sda1               1          37      297171   83  Linux

Normally I am able to partition but start sector comes as either 1024 or 63. I want it to start at 1. The HDD is 2TB.


You can't because of the reserved sectors for the bootloader allocation. In normal situations, there's no practical reason to do this anyway.

  • I want to add bootloader of the NAS on it. – Samir Sogay May 2 '14 at 10:03
  • Then use whatever tool the OS of your NAS provides. – Nathan C May 2 '14 at 14:01

I am quite sure, the 1 / 37 geometry is meant to be cylinders (in the old CHS-speak), not blocks: STarting block 1, Ending block 37 might not easily result in 297171 blocks ...

Switch to blocks as display unit on the original disk, I am quite positive, it will show up as 63
