    I have a 500GB Momentus XT Hybrid drive in my 13" 2.53gHz MBP. I updated from firmware SD24 to 25 with no problems by burning the .iso image file onto a CD and booting from that. However when I now have tried to do the same to update now from SD25 to SD28 (supposed to work better with Lion and the recovery partition), my MBP will not recognise the burnt CD with the new SD28 .iso file as bootable. I have downloaded the .iso file twice and burnt two discs, using different Macs with the same result. I tried to force it to boot from the CD by holding down the C key, while starting - no joy.

    It has been suggested that I copy the .iso file to my iMac, connect the MBP to the iMac with an FW400/800 cable (I have one) and restart the MBP in target mode. However I am not sure how then to run the .iso file on the Momentus XT HD, now in target mode. Both MBP and iMac are running 10.7.2.

    Any suggestion folks?

    I also have a bootable version of Lion on an SD card, so could put the .iso file on that and boot the MBP from there.

    When you open up the disc that you burned, is the ISO file on the disc or did you burn the contents of the ISO file to the disc? Describe in more detail what you did, but it sounds like you just put the ISO file itself on the disc rather than burn the contents to disc.

    Actually burnt the file

    Both times I tried, downloading the file via different routes and using different combo drives, I burnt the file onto the CD-R. I even did a cross verify afterwards to check that the .iso file had burnt properly and a hex peek as well. I am wondering if now that I have two partitions on my HD for Lion, that might be why the CD with the .iso file is not recognised as bootable. Going to Lion is the only thing that has changed on my MBP since I successfully upgraded the FW from SD24 to SD25 by the same method. I am wondering also if the .iso file is corrupt on Seagate's website.

    FW update designed to run in DOS

    I have done a bit more poking about inside the .iso file, which is actually a package. It would seem that the upgrader is designed to run in DOS and has lots of .exe files, so I would be very surprised if it was recognised as bootable by a Mac. I think Seagate may have dropped the ball here. There are multiple levels of folders and dozens of files in the .iso package. There may well be a bootable structure buried in there somewhere but it needs a lot more in the way of instructions from Seagate to extract it and burn the correct bit(s) onto a CD-R. Seagate's latest suggestion to me is to extract my HD from the MBP and update it on a Windoze machine - yerchhhh!

    You're burning it wrong. Open up Disk Utility, click the Burn button and navigate to the ISO file. That will then put the contents of the ISO onto the disc and you'll be able to boot from it.
