New HDD

[Mr.Lindblom]

My hdd is broken and i wonder in i just can replace it with any other sata disk? :hammerhead

[fvdw]

in principle yes. But if you have a nwsp2 classic with old bootloader software then the max size is 2 TB
We have a new bootloader making it possible to use bigger disks on those devices as well, but flashing the bootloader is always a risk.

Further I would advise to use a low power disk that runs at speeds of 5900 rpm, those generate less heat and that is a benefit because the nwsp2 doesn't has a fan and can overheat.

I have a new hdd "WD caviar green 2TB" but it starts on sector 64 in fdisk?

[Mr.Lindblom]

I figured it out my self. U can switch between sectors and blocks in fdisk with U.

[Jocko]

You are right :thumbup

(but in lowercase ;) )

[Mr.Lindblom]

Now i have a new problem.
I have bought a WD Caviar green 2TB and cant get it working.
I think it is in Advance Format and should have a diffrent partition table .
Can some one help whit this?
I am new to Linux and i am sorry for my bad english.

Hi Mr Lindblom,

Yes, if your disk is an AF HDD, you mustn't use the standard partition table.

but easy to do same instructions : just change the start and end of each partition.

So with fdisk and using cylinder (option u), the new partition table is for the 2TB HDD:

Partition 1 start 9 end 72
partition 2 start 73 end 136
partition 3 start 137 en 200
partition 4 start 201 end 243200
Partition 5 start 209 end 312
Partition 6 start 321 end 328
Partition 7 start 337 end 400
Partition 8 start 409 end 243200

(See post http://www.plugout.net/viewtopic.php?f=11&p=4394#p4394)


Note : if in your fdisk output the logical sectors size is 4kB see this post http://www.plugout.net/viewtopic.php?f=7&t=991

Note 2 : what thing you make think that you have an AF disk ? (wrong align warming when you create the partition ?)

[Mr.Lindblom]

Hello again!
I think that for the sector size is 512/4096.
And partition 6, 7 and 8 does not start on physical sector boundary.
Feel free to correct me if I'm wrong.
I have almost no experience in Linux

Your partition table is not right (~ standard table : for example partition 1 the end cylinder is 64 :disapprove )

Note : please post the fdisk output with cylinders layout

So you must change this in the howtodo :

Step (i). create the new partition table and store on the disk
Start again fdisk
fdisk /dev/sdb

create partition 1
use the command: n
it will respond with
command action
e extended
p primary (1-4)
type p as command and hit enter
now you get as response
Partition number (1-4):
type 1 behind it and hit enter
then you get as response
first cylinder 1-243201, default 1):
type 9 behind it and hit enter
response
last cylinder or...:
type 72 behind it and hit enter

create partition 2
n
p
2
73
136

create partition 3
n
p
3
137
200
make partition 3 type swap
type t as command
enter partition number 3
enter as hex code 82

create partition 4 (this is an extended partition)
n
e <---note the difference !!
4
201
243200(not 243201 !)
create partition 5 (no choice possible anymore for primary of extended, the additional partition will be made automatically in the extended partition)
n
209
312

create partition 6
n
321
328

create partition 7
n
337
400

create partition 8
n
409
243200

Now use the command p to check the partition table
if it's right the command w to write the partition table

And resume the following steps described in the howtodo

[Mr.Lindblom]

Works fine now!
I thank you very much.
Now I'll just learn how it works
