I have been futzing around with this problem for almost three weeks now. I have yet to find the right solution. Here is the scenario. Am running XP Pro on a 120 GB drive with SP3 and IE7 installed. It works perfectly. This is a PATA drive on a P4 system. I would like to clone the 120 GB drive to a 150 GB drive. I have done it with TI 10, T1-11, directly (PATA to PATA) and indirectly with one drive in an external USB case. The cloning goes AOK - proportionally - according to TI. But the resulting product will not boot. It starts to load Windows XP, and then keeps going with the passing blue squares until it gets a BSOD flash and reboots. I have tried AS IS and porportionally. I have used Windows ASR.m Nothing really works right. Is the problem SP3? Suggestions?
