How to deal with the problem that copying drives with different block sizes is not supported? Refer to this article and solve the problem with the best software.

The case

I've been running into clone problems lately with 1TB hard drives. HDClone gives me an error saying different block sizes aren't supported. Clonezilla won't work either and it's really a bother to do a clean install and migration manually. Karen's Replicator is another possibility that I've considered but it's a bit time-consuming, especially with hard drives that have multiple partitions.

Why copy drives with different block sizes?

When it comes to copying drives with different block sizes, you first need to know what the disk block size is. In computing, a sector is a subdivision of a track on a disk. A block is actually a group of sectors. As for the disk block size, it is the size of a block in file systems and data storage.

In our daily life, we often need to clone hard drive with different block sizes for various reasons. There are two main reasons as below.

  •  Hard drive upgrade. Users usually clone their old hard drive to a larger hard drive for a big capacity because of insufficient disk space. Some people also clone the old hard disk drive to a solid state disk for a good performance.

  • Hard drive backup. To prevent data from being lost, some users choose to clone the hard drive to another hard drive just in case.
