"Insufficient Space on Target Volume" Error Message Moving a Folder with SBS Move Folder Wizard

• Microsoft BackOffice Small Business Server version 4.5

SYMPTOMS

When you try to move a folder by using the Move Folder Wizard, you may receive the following error message:

Insufficient space on target volume.

CAUSE

The problem can occur because of an overflow error. The variable type used for the free drive space is a DWORD. This variable type has an upper limit of 4294967296. If the amount of free space on the drive is larger than this number (4 gigabytes, 4096 megabytes, or more) the value is truncated, resulting in a smaller value.

For example, a drive with 4100 megabytes (MB) of free space will appear to have approximately 4-MB of free space. The same process occurs at approximately 8-GB, 12-GB, and so on when the overflow re-occurs.

RESOLUTION

To work around this problem:

1. Create a temporary folder on the destination drive.



2. Copy the source folder to the temporary folder on the destination drive by using Windows Explorer.



3. After the folder is copied, use the SBS Move Folder Wizard to move the original source folder on the source drive to the destination drive.



4. Delete the temporary folder on the destination drive to free disk space.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.
