USB live media boot error

Dear all,

I burned opensuse 13.1 live iso to USB 8GB pendrive using dd:

At boot, I get some "Assuming write though" errors and various other, and gives a 120 second reboot timeout.

I also tried "Verify" rather than "Live Boot" at gfx boot prompt. It said iso verification failed. Hoever, I was able to run the same ISO file with KVM and worked fine.
Once I boot the live media, it seems I need to redo "dd" again, since the drive is not anymore detected as bootable. Opensuse is trying to do something on the live USB media - like creating some other paritions. (probably a boot flag need to be switched but that not the main problem).

I think this problem is somehow specific to *me* since I also tried burning arch linux on the same drive with dd, but it also failed telling it cant mount so and so things. My media is fresh - I just bought it today!

I also tried doing this on a 4GB microSD connected through my phone, using both dd and unetbootin - both failed. Its weird because I've done this a 1000 times - and that was just about 6 months back. What has changed so much ???

Here is the photo of the errors it showed: http://imgur.com/jOhM5yl

Please help me fix the issue.
