Can I dd if=/dev/sda of=/dev/sdd3 (copy drive to partition) ? Will it be a problem?

The source and destination drives with their respective partitions are as follows:

--Source Drive details--

Disk /dev/sda: 250.1 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x000551f2

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1       29300   235346944   83  Linux
/dev/sda2           29300       30402     8849409    5  Extended
/dev/sda5           29300       30402     8849408   82  Linux swap / Solaris

Yes, it will be a problem. Drives contain a partition table, partitions do not. What is it that you are really trying to do?

Yes it will be a problem , Because Each and Every partition Using Different UUID, So Try to Get the UUID Information of Both Drive Which u going to restore and backup , Here u have mentioned the destination Drives are in NTFS Format so sure u going to face issue
