-	// Most of the time partitions are aligned to whole MiBs so the writing of zeros
-	// at offsets -64 KiB and -8 KiB will be overwriting zeros already just written
-	// at offset -512 KiB, length 512 KiB.  This will double write 12 KiB of zeros.
-	// However partitions don't have to be MiB aligned and real disk drives generally
-	// aren't an exact multiple of 1024^2 bytes in size either.  So zeroing at offsets
-	// -64 KiB and -8 KiB with their smaller rounding / alignment requirements will
-	// write outside the -512 KiB zeroed region and needs to be kept.  Because of the
-	// small amount of double writing it is not worth the effort to suppress it when
