Single Red Light of Death?

today when i went to play my 360, a single red light began flashing (the bottom right one) and an error message appears on screen. i went to the microsoft tech site and it said to unplg everything and plug it back in. i did that and nothing has changed, im just wondering does microsoft cover this in their warrenty or do i have to pay $200 to have it fixed? i plan on calling the support line tomorrow, but i just wanna know if anyone else has had this problem.

i have had it for a few months, i hope they will replace it for free

Take off your hardrive and turn on the 360 and tell em if it works. One red light is a hard drive problem.(overheating is 2 red lights) The message is:

E-67

or

E-68

or

E-69

right?

Your hide drive isnt conencted properly or is damaged. ( i would know because mine was when i first got it. I put alot of stuff on top fo the 360 when i was christmas shopping......)
