i got a normal message for a update as usual today. as the update was half way done.i got a error code for lost signal. so i tried again but this time my x box was making "scratching" sound and got a e68. I used the trouble shoot guide and no dice. so i decide to use my old 4gb hard drive and the Xbox run finds. so todays update corrupted my 250gb hard drive. did any1 ever had this problem and able to fix this?
