    I have installed a OWC SSD into the second tray on my Mac Pro 2010. However, when I shut down and start up, it always starts up on the original 1TB WD that came with the unit. I cloned my SSD from WD and everything works fine. The start-up of the SSD was a little slow and I was told to do a PRAM reset, which I did, but then I noticed that it was the WD 1TB again on startup.
    I even locked in preferences after choosing the SSD for startup disk, but on shutting down and starting again, still starts up on the WD.
    How do I choose the SSD and keep it as the startup disk.

    System preferences --> Startup Disk ---> select your disk. Apply. TaDa

    The only method I know is by selecting the boot disk you want in system preferences and then restarting (not shut down and start up). It always worked for me however lately I am not able to see my Windows partitions. :(

    I don't know why it is not working for you. Wait for others to shed more light on the situation.

    There is always the option of removing the HDD from the drive bay (or formatting it) thus forcing it to always boot from the SSD.

    Edit: talmy and beto2k7 beat me to it.

    if you format the disk in windows without doing it by bootcamp assistant first, or if you format it in a PC, the disk will have MBR partition table instead of GUID, and Startup Disk will not see it

    I have a Windows Vista partition on my iMac that was partitioned using bootcamp. It was working on 10.5 and on 10.6 but after a point update I lost the functionality.

    On my Mac Pro I have an SSD that was formatted using Windows 7 and I had the functionality when using 10.6.4 (the version the Mac Pro shipped with) however after applying the combo update 10.6.6 I lost the facility.

    I can not say what is the partition type as I am on my iPad I will check later on today.

    Thanks for the info

    ntfs-3g or the tuxera NTFS driver will cause windows boot disks to disappear from the startup disk control panel as well. it's still possible to set them as the default boot drive for the machine by using the bootcamp control panel in Windows.

    Sorry for the big delay but I was extremely busy.

    Mac Pro - The SSD is set up with a MBR partition table. However the strange thing is that when I was on 10.6.4 I was able to see the Windows 7 partition.

    iMac - The Windows is on a partition on the main drive and has a GUID partition table. I have a NTFS driver (as far as I know it is paragon) I got it as a limited functionality demo from it think Macworld or some other Mac related print magazines. The thing is that the NTFS driver was installed when I was still on Leopard. I jumped to Snow Leopard in the first week it was released and the Windows partition was visible under system preference. I think the partition was visible under System preference until 10.6.5.

    P.S. Due to performance and stability issues with 10.6.6 (regarding NTFS drives) the Windows partitions are in the exclusion list for spotlight indexing.
