Please help (Dear God, I promise I will be good if this can be fixed)

My System XP SP3

I have Acronis True Image Home 2009, and performed a full back up to an external usb HDD October 2011, creating a 6 gig tib file. I performed a full system restore (using the same Oct 2011 file) in February 2012 with no problems. Today I have to perform a system restore again (using the same file from Oct 2011). I clicked "restore", then "browse for backup", then "Restore whole disks and partitions" pointed to the tib file on the usb drive. Under "content selection", i clicked "Disk 1" and it automatically checked "NTFS (unlabled c:) and "mbr and track 0" (which i have no idea what mbr and track 0 means). then the partition destination box popped up asked me to select the disk. i chose the unallocated disk1 (not the usb hdd disk 2) . Then clicked Next. The "Congratulations" box popped up and it asked me to click summary, which i did.

Then the summary operations box popped up, saying the following: Restoring partition, hard disk 1, drive letter c:>h, file system ntfs, volume lable (blank), size 111 gb. i then clicked "Proceed"

Then the "operation progress" box popped up and the restore started - 1 of 1 restoring partition - 34 minutes remaining, the countdown continued, 15 mins, 10, 8, 5, then it stops with an error message "Restore operation failed". no other messages given. I have tried this 4 times with the same result.

I need help badly. Thank you
