msi 770-c45 with AHCI ubuntu 12 does nt reconize the hdd
 

what can i do?
if i go to disk utility i see the hard drive.
but the installer does nt.
if i use IDE mode it does work but i guess it will work slower.

thxs in advance

Try this, this seems to help sometimes:
1. Start Ubuntu in live mode.
2. Start a terminal and remove the dmraid program:3. Now start the installer and try it again.

i get this error when i did that

ubuntu@ubuntu:~$ sudo apt-get remove dmraid

ubuntu@ubuntu:~$ sudo apt-get remove dmraid


any idea?
