Seagate Momentus XT firmware SD24 upgrade on OSX via USB
I am having a hard time upgrading my Seagate Momentus XT ST95005620AS to firmware SD24 on Snow Leopard 10.6.7. My main problem is getting a USB drive to boot the firmware.
The ISO image I am trying to use was downloaded from here:
http://www.seagate.com/staticfiles/support/downloads/firmware/MomentusXT-ALL-SD2 4.iso
I am using a 4 GB Kingston DataTraveler G2 pen drive.
The first thing I've tried was to open DiskUtility, partition the pen drive to a single MS-DOS (FAT) partition (using MBR) and then restoring the ISO into the drive. I did that by:
1) Selecting the partition I created on the usb stick.
2) Selecting the "Restore" tab.
3) Dragging the ISO image file into "Source".
4) Dragging the USB partition into the "Destination".
5) Clicking Restore.
The error I get is: "Restore Failed" "Could not validate source - Invalid argument".
I've tried fiddling with the options by first mounting the ISO and then dragging the mounted volume into Source, as well as dragging the USB Volume into Destination. I've also tried other partition methods (GUID).
I've also tried copying the ISO image straight to the USB disk via the Terminal, by:
1) Unmount the USB Partition (diskutil umountDisk /dev/disk1).
2) Copying the ISO into the USB stick (dd if=SD24.iso of=/dev/disk1) or (of=/dev/disk1s1) or even (of=/dev/disk1s2 when using GUID).
Although I manage to (apparently) put the data in the stick when using the Terminal method, the USB is not bootable (pressing Option on during boot doesn't show any options apart from my main disk).
What am I missing?
