SSD trouble?

I post this one here, it is more SSD ( hardware ) related, than something else...

I'm trying to install arch on a Kingston SSDNow (S-series) 16 Gb SSD, and I've notcied something.
Following the SSD wiki, I've tried to run fdisk to get a new partition table, etc ( I don't want to use gdisk here ) with the command :

CODE -------------------------------------------
# fdisk -H 32 -S 32 /dev/sdb # where my SSD is /dev/sdb

but the command does not give me anything like in the Wiki:

CODE -------------------------------------------
# fdisk -H 32 -S 32 /dev/sdb

command ( m=...

later on, it said that the first cylinder was number 2048...

strange

I don't really want to mess it up, so am I right, if I think that something is wrong here?
(I dont want to have 31277232 sectors, dammit! )

So, what is wrong? I've missed something?

I JUST WANT TO FDISK IT to have 512 KiB alignment!

Re: SSD trouble?

I did it the easy way

1- booted into a parted magic disc
2- Used GParted + chose default msdos partition table
3- created new ext4 partition as / (single partition), it auto-aligns the start to 2048
4- install arch on /

You can do this with multiple partitions obviously. I didn't want to risk aligning by command line I'd say this is a safe way you can't go wrong.

Edit- why is 2048 bad? It doesn't matter as long as it's divisible by 512 and it's fine to use 2048 if your erase block size is 512

Re: SSD trouble?

SOLVED!

Re: SSD trouble?

Yea, I did it the parted magic way after trying to partition it using Arch install, but it ended up unaligned and TRIM didn't work. I don't mind doing things by command line but partitioning is annoying, esepcially after you've installed Arch then find out it's wrong. GParted is the easiest and most reliable way for me you can't go wrong with it
