Re: Small unallocated space automatically created

Hello all,

Thank you for choosing Acronis Disk Director Suite 10.0

Please accept our apologies for the delay with the response.

churin, the exact size of the space created is not clear from message.

However, let us explain one thing, it is related to 7,8 MB's of unallocated
space on each drive.

There are two situations in which partitioning software (i.e. Acronis Disk
Director) can detect an area of unallocated space of up to 7.8 MB in size
that was not created there manually:

1. Up to 7.8 MB (minimum of 1MB) of unallocated space resides in the end of
the hard disk. This area is reserved by Windows (NT family) operating
systems for the purpose of creation of Dynamic Disk structures. This
unallocated space area is not shown by Windows Disk Management; however
Acronis Disk Director is able to merge it with an adjacent partition.
Therefore, after doing that there can be problems with creating Dynamic Disk

2. Exactly 7.8 MB of unallocated space reside in the beginning of the hard
disk. Normally this means that there are no Primary partitions on the hard
drive and the hard drive contains an Extended partition only. In such cases
Windows reserves the minimal amount needed for creating a partition (7.8 MB)
in order to be able to handle the only Extended partition properly. It is
not recommended to remove this area. Even though technically it is possible
to merge it with the Extended partition, this may result in the data on it
becoming inaccessible.

Detailed information about Acronis Disk Director product can be found in
User's Guide.

Thank you.
