are you sure you are not have set fdisk to sectors instead of cylinders ?
(you an toggel between the two using the "u" command in fdisk (without the quotes)

Also if you have an advanced format disk then the story becomes different (see other posts for instance in nwsp2 forum)
On a conventional disk sector size is 512 bytes, on advanced format 4096. if your sector size is 2048 then its a strange setting

dd if=/path-to-mbr-img/spd8020-mbr.img of=/dev/sdb bs=512 count=1
dd if=/path-to-file/spd8020-sda1.img of=/dev/sdb1

both commands do not work

:tapfoot you must replace "path-to-mbr-img" and "path-to-file" by the actual path.
For instance if you stored them on the pc running linux in a folder with name /test
then the command becomes
Code: Select all
dd if=/test/spd8020-mbr.img of=/dev/sdb bs=512 count=1

no not on a spd8020, the bootloader only supports a dos partition table which means you are stuck with max size for HDD of 2.2 TB.
To use a bigger disk you need a GPT partioned disk but the bootloader will not be able to read the disk and load the kernel. The kernel in our firmware supports GPT disk but of course first it must be loaded.
There are tricks which could enable use of bigger disks but not in standard setup. I could compile a new version of the bootloader to enable GPT support but it is big risk, if the new bootloader doesn't run your spd8020 will no longer boot and is will become a brick that only can be revived with special tools.

Thanks for fast reply,
if it's too complex it's no problem - I can also use the hdd 2TB.

Anyway, thanks for your professional work
