    Ubuntu 10.4 Installation on SATA 6Gb/s

    Hey guys,

    Long time user of Ubuntu, but i've never had this problem.

    I just recently installed Ubuntu on my SSD partitioned with Win7. Everything worked fine.

    I decided to move my SSD from the SATA 3Gb/s port to the 6Gb/s port on my motherboard for better performance. Grub 2 is still recognized and Win7 boots properly.

    However Ubuntu will not boot after selecting it from Grub. I also tried to reinstall over the ext4 partition on my SSD with a live CD and it does not recognize my SSD, only my data drive.

    I am lost. Is Ubuntu 10.4 not compatible with SATA 6Gb/s or am i just missing something?

    Thanks.

    Is your ssd rated sata II or sata III?

    It is rated for SATA II. However, i know that plugging it into SATA III would not hurt anything. Grub 2 and Win7 still work...

    I originally changed ports in the first place to avoid this annoying "HD not found" message from by bios because it always checked the SATA III ports before the SATA II.

    I thought that SATA was all backwards compatible.

    The point is that you are gaining nothing else than avoiding the annoying message by plugging a sata II drive into a sata III port. SATA is backwards compatible in theory, but you may be encountering an unpredictable problem with timing or something. I would change the seek order in bios, if you can, to boot 1st from the slower port.

    I am having the exact same problem as babydanks. The only difference is that my harddrive is actually a SATA III drive and I am still having problems. Windows XP x64 works perfectly, but Ubuntu requires me to plug my drive into a SATA II port on my motherboard. It is somewhat upsetting. I would appreciate any feedback and please explain most of your instructions as I am relatively new to linux. Thank you.

    Just a thought. Try editing in 'rootdelay=90' to the grub menu boot line. If it is helpful you can make it permanent in /etc/default/grub.

    i believe you press "e" on the grub menu and edit the kernel line to say 'rootdelay=90' is that correct? i tried it. i still get the busy box saying that /dev/disk/by-uuid/# does not exist. and it gave up waiting on the device. same thing happened with 'rootdelay=1000'

    It did not work for me either. I got that busybox as well.

    Had this problem also with 64bit 10.04, msi p55gd85 i7 870 and 6 g SATA hdd.

    If anyone got it to work in their installation, post.

SATA 6 GB/s is futureproof I guess, but at this point mostly just marketing. Two drives differing only in the interface will have equal performance.
