If restoring to another drive, it may be best to create the partition as desired and then restore into it or restore the Entire Disk Image and then use Disk Management to resize it. It would only allow fractional values: 0.461, 0.954, 1.446, etc.
In some tests, TI would not let me enter 1MB into the box. I think this alignment should still be okay, but I don't understand why TI is changing the entered offset. However, this resulted in the restored partition having 2MB before (starting sector 4,096) instead of 1MB (starting sector 2048). In several tests, I could enter 1MB into the "space before" box. Restoring the first partition to a unallocated drive also reverted to the 63 sector offset/alignment. If left at 0, the 63 sector offset/alignment is used for the restored partition. When I tried to resize the first partition as part of the restore process, TI would reset the "space before" value to 0. For example: After restoring the first partition, the starting offset was still 2048. Restoring a partition back into its existing space kept the offset/alignment. This is consistent with previous versions. Restoring an Entire Disk Image keeps the offset/alignment. All tests were done using the Full Mode (Linux-based) version of TI. The first partition was 20GB and started at offset 2048 (1MB). My test drive had two partitions created with Vista. The results are not what I expected, but they're better than previous versions.
I've run several tests in a VM using TI 2010 (build 5,055) to check how the offset is handled.
