ps if you use fdisk then you can easily switch between sectors and cylinders using the "u" command option
No this is not normal what you describe. It means it don't find a harddisk. Most likely it is not formatted correctly and the bootloader cannot read the disk
The sector size you mention indicates that you have an advanced format format disk. If that disk can not emulate the classic sector size of 512 bytes and you formattted it using GPT partition table the and your nwsp2 is a classic one then the bootloader of the nwsp2 will not be able to read it.
Did you format it using a GPT table? If so then it won't work as the nwsp2 classic can not read disks formatted in GPT. If you you have a nwsp2 Lite then it should be able to read the disk but it won't boot as the kernel of fvdw-sl doesn't support yet GPT (EFI) formatted disks. The kernel of version 13 supports it, but it is only of use for the nwsp2 lite.
If you hae a nwsp2 classic then and the disk is < 2.2 TB then you should format it using fdisk (=ms-dos partition table)
So to solve your issue we need to know a little more
(1) what nwsp2 do you have
(2) what harddisk are you using size, brand and advanced format yes/no
(3) how did you format it
lf you have an advanced format disk the you should modify the partition table to be used to align partitions with physical sectors, if you don't do it then it can cause severe performance loss on reading and writing to the disk. Some brands have special measures in the software of the drive that let you use the drive just like a 512 bytes one. You need to check on the internet.
