Acronis Tech Support: I suspected that TrueImage was failing to copy all sectors from a hard drive that it was supposed to create an image of. That is now confirmed. Here's what happens: 1) Dell sends out warranty replacement hard drives with a preloaded image of the customer's op system, trial and purchased software. When the warranty drive is installed and booted for the first time, a Dell setup program autoexecutes and creates the C partition. This setup program installs the operating system and all other software, and also creates the hidden diagnostic and restore partitions, automatically restarting as necessary. 2) When the autoexecuting setup program has completed its task, the warranty drive is fully functional and includes the C partition, the Dell Diagnostic partition and the Dell PC Restore partition just like the hard drive that was originally installed when the computer was built. 3) I received a warranty replacement drive with the Dell autoexecuting image on it and decided to create a TI8 image of it for later restore. 4) I installed the warranty replacement drive in an external USB enclosure and booted from my BartPE CD with the Acronis plugin. I created an image of the warranty replacement drive and saved it to a second USB external drive. 5) I disconnected the warranty replacement drive and rebooted with my BartPE CD and restored the image from my USB external drive to my internal hard drive. I shut down and disconnected everything from my computer. 6) I tried to boot with the restored image of the Dell warranty replacement drive and after POST, the boot process failed with the message "PBR 2 complete, Missing Loader". True Image failed to copy all sectors of the warranty replacement hard drive. The image was restored but with missing critical boot data such as Dell's autoexecute setup program information. Just to be sure, I repeated this exact process using the TI8 build 937 CD and the TI9 build 2302 boot CD. None of these CD's captured the missing sector information. Then, I tried creating an image of the warranty replacement drive using TI8 build 937 and TI9 build 2302 installed on my internal hard drive. The image was created and saved to the external USB drive and then restored to the internal hard drive and it also failed to boot with the same error messages. Of course, when I actually installed the Dell warranty replacement drive in my computer, it autoexecuted and created partitions, etc. and worked perfectly as it was originally imaged by Dell's facility to do. This indicates to me that TrueImage does NOT capture all sectors of the target hard drive that contain data but rather captures what Acronis developers have previously determined is relevant, in their judgment. What is really happening here and why can't images of these warranty replacement drives be successfully created and restored? Edited to clarify this sentence: Of course, when I actually installed the Dell warranty replacement drive in my computer, it autoexecuted and created partitions, etc. and worked perfectly as it was originally imaged by Dell's facility to do.
