Erroneous entries in the MFT were found during the defragmentation. The drive<br />
should be checked for errors.<br />
O&O <strong>Defrag</strong> guarantees you complete data integrity and security. Only functions that are implemented in Windows<br />
by the operating system itself are used for defragmentation and synchronization of all file accesses.<br />
File attributes (Date, Time, System, Archive etc.) and the security settings for NTFS drives will not be changed.<br />
Access rights also remain unchanged. In addition, only one file per drive will be processed at any one time. This<br />
ensures that even in a worst case scenario, only one file will be lost (e.g. if there is a power cut). If you have more<br />
questions concerning data security, we can provide you with more information. Do not hesitate to contact us at:<br />

Supported hardware<br />
O&O <strong>Defrag</strong> supports all hardware components that are supported by Windows. Please note the software requirements<br />
of the corresponding manufacturer.<br />
As a rule: if you can access your hardware with Windows as you would a normal Windows partition, and this partition<br />
is formatted using a supported file system, this hardware can be defragmented. Removable drives such as<br />
streamers or CD-RWs are exceptions, since defragmenting them might not be useful. You can also set network<br />
drives as target for defragmentation.<br />
RAID<br />
Striped-, Mirrored- and RAID5-Volumes: The advantage of these drive types lies in their superior speed, which on<br />
the one side facilitates accessing and storing processes, and on the other hand offer a higher degree of data security.<br />
O&O <strong>Defrag</strong> supports all known RAID systems. According to many hardware manufacturers, defragmenting RAID<br />
systems is especially important: as their files are spread over several hard disks, their fragmentation level is likely to<br />
be very high.<br />
Supported File Systems<br />
O&O <strong>Defrag</strong> supports all Windows file systems. The following paragraphs will tell you more about each of these file<br />
systems.<br />
File System Explanation<br />
exFAT Starting from Windows Vista, the exFAT-file system is supported.<br />
