We use the WindowsAPI functions to determine the user names. Unfortunately, the Netware client for Windows does not provide information about the owners through the normal Windows API functions. That's why Novel and Linux (some Samba versions) have this problem. However, all other functions are also available on Netware drives without restrictions.
Open the Configure Scans dialog ("Scan > Configure Scans") and choose "Check Data Consistency" on the tab "Expert Settings" for the relevant scan. This option will check and correct the database consistency of the selected scans. The operation could take some time. In the meantime there will be "Check data consistency" shown in the status field. You must not terminate SpaceObServer while this operation is performing. Please execute an update scan after the operation is done. In case the update scan did not resolve the problem, please contact us.
Select in the Details view ("Tools > Options > View > Details") only the columns you need and hide the other ones. Please find a list of very costly columns in the chapter "Available Columns". In case the selected directory is on a network drive, the detection of the file icons could take some time. To prevent this please activate the option "Determine Icons based on File Extension only" ("Tools > Options > View > General").
The Windows Explorer shows the space that is physically allocated on the drive while SpaceObServer shows the space that is occupied by all files under a certain path. Please make sure that you have the view option "Allocated Space" activated when you are interested in the physically allocated space. Beyond the space that is needed for storing the files itself, additional space is used for storing management data like the File Allocation Table of the file system or the boot sector. This is usually 0.5 - 2% of the occupied space. It is not possible to free this space with SpaceObServer or any other tool. Another possibility is that you are using a Software RAID - like Windows offers it - which spreads the data with redundancy over several disks. These disks will appear as one logical volume and the failure of a single disk will not cause any data loss. But for storing the redundant information additional space is needed.
On Thinkpad laptops the Rescue&Recovery feature may use a lot of disk space in the folder "RRBackup" which is not accessible to other applications.
If a drive letter points to a sub folder of a network drive, the allocated space (correctly) reported by SpaceObServer may also be much smaller than the physically allocated space on this drive reported by the Windows Explorer because it is possible the whole drive is not accessible through the network. A further possibility is that not all parts of the drive could be scanned due to access restrictions. Turning on the Option "Track NTFS Alternate Data Streams and NTFS Hardlinks" in the "Configure Scans" dialog may result to more accurate results but slightly slows down scans.
This is possible with the help of our monitoring tool ServerSentinel. It is designed to automatically monitor local resources as well as server and network services. For more information, as well as an overview of these and other available functions, please visit our website.
