SSD not recognized

toneman77 · 04-17-2009, 02:41 PM

ok. I found some nice scripts here: http://www.kroah.com/lkn/ (Chapter 7) a way to find which driver is used for a device.
So I started the live CD that recognizes the disk and got:

Code:

looking at sysfs device: /sys/block/sda
follow 'device' link to parent: /sys/devices/pci0000:00/0000:00:0b.0/host0/target0:0:0/0:0:0:0
found driver: sd
found driver: ahci from module: ahci

So I thought: boot up the newer live CD and modprobe these two modules...

Code:

ubuntu@ubuntu:~$ uname -a
Linux ubuntu 2.6.28-11-generic #41-Ubuntu SMP Wed Apr 8 04:38:53 UTC 2009 i686 GNU/Linux

ubuntu@ubuntu:~$ sudo modprobe sd
FATAL: Module sd not found.
ubuntu@ubuntu:~$ sudo modprobe ahci
FATAL: Module ahci not found.

Is there a way to get these modules load somehow? Or did I understand sth wrong here? (drivers/modules)
Any ideas welcomes

Maybe they are built-in and not as modules. Check the kernel config of the Ubuntu kernel. If you're running Ubuntu you can also do:

Code:

bash-3.1$ zcat /proc/config.gz | grep AHCI
CONFIG_SATA_AHCI=y

Here ahci is built-in, so you can't modprobe it. If it says 'n' then it isn't built at all. In which case you need another kernel, either compile one yourself or look for one.

what I found out till today:
Vendor ID for the disk/controller is 0x10de
Device ID is 0x0ab8

Funny thing is that this device id is known in 2.6.28 in the file ahci.c but not in 2.6.22
2.6.22 kernels recognize the disk (ubuntu 7.10 gutsy, debian lenny), 2.6.28 dont.

I dont know if that has sth to do with my problem but it's driving me nuts.

Any further ideas?

anyone with an idea or a push in the right direction?

You haven't answered H_TeXMeX_H's question, except that for the 'buntus that file is /boot/grub/config-*

I'm sorry, thanks for the hint

In the 2.6.28 kernel I get:

Code:

CONFIG_SATA_AHCI=y

In the 2.6.22 kernel (at least debian lenny, can't check the ubuntu one right now) I get:

Code:

CONFIG_SATA_AHCI=m

In that case you could try compiling ahci and sd as modules, not sure if that would help tho. It may help if you remove other potentially conflicting drivers.

Hello
I built a 2.6.28-9 and a 2.6.29-3 kernel with ahci and sd as modules. I got the same error, the disk wasn't recognized

H_TeXMeX_H · 05-16-2009, 04:33 AM

What if you compile a 2.6.22 and use that, does it work ?

toneman77 · 05-16-2009, 04:38 AM

the 2.6.22 kernels i tried have that as a module. these are the only ones (i didnt try older ones) that recognize the disk.
Or do u mean i should try compiling them in a 2.6.22 kernel not as a module but directly?

H_TeXMeX_H · 05-16-2009, 04:56 AM

I'm saying if it works with these kernel versions, compile your own kernel of this version in distros that normally have later/other versions. I can't think of anything else.

Hi everybody,

has there been a solution for the problem toneman77 has described?
I am facing exactly the same problem. All the suggestions I found so far did not help at all.

My hardware:
HAMA SATA 16GB SSD
ASRock ALiveNF7G-HDready (nForce 630A MCP Chipset)

Any help would be appreciated!
