Acronis Migrate Easy supports disks of any size

Acronis Drive Cleanser 6.0 works with disks of any size

Two or more disks that make a dynamic volume show the size of the volume itself in Acronis Disk Director Lite

If there are both ShadowProtect and Acronis Backup & Recovery 10 Agent for Windows installed on the same machine and you back up with VSS enabled, the incremental and differential backups will be of the same size as the full ones

When running Acronis Disk Director 10.0 under Windows the only limitation of disk capacity is the one of Windows. If you are running Acronis Disk Director 10.0 from bootable media, then you can work with disks of any capacity without limitations.

When creating a master image using Linux bootable media, the size of created image is bigger than expected - the image is created in sector-by-sector mode. This issue occurs only, when using Windows Drive Management tool to resize partitions before.

You need to have unallocated space on the disk with the partition the size of which you intend to increase

Acronis Disk Director only supports disks with 512 bytes logical sector size

If the capacity of the cloned drive is the same with original drive, whereas it should not be, then the issue is caused by Host Protected Area

MS Virtual PC cannot boot from a .vhd disk larger than 127 GB

This is a warning that is safe to ignore. Warning has been removed from the latest build of Acronis Backup & Recovery 11, please update the product.
