General Information:
|
|
|
|
This test suite is designed to be used with volumes of 1GB in size,
|
|
which allows for a really short processing time.
|
|
|
|
It is used on a virtual machine to test the algorithm.
|
|
|
|
The following file systems are supported:
|
|
|
|
1) FAT
|
|
2) FAT32
|
|
3) exFAT (1)
|
|
4) NTFS
|
|
5) NTFS compressed
|
|
(with compression enabled)
|
|
6) NTFS mixed
|
|
(with 25% of compressed files, which mimics a regular system disk)
|
|
7) UDF v1.02 (2)
|
|
8) UDF v1.50 (2)
|
|
9) UDF v2.00 (2)
|
|
10) UDF v2.01 (2)
|
|
11) UDF v2.50 (2)
|
|
12) UDF v2.50 with duplicated meta-data (2)
|
|
|
|
The fragmentation utility from http://www.mydefrag.com/ is used to create
|
|
fragmented files.
|
|
|
|
For cloning the disks to test different settings on the same data you may use
|
|
HDClone available freely at http://www.miray.de/products/sat.hdclone.html
|
|
|
|
You can change the number of fragmented files by not formating the drive.
|
|
This way the current files will be fragmented.
|
|
|
|
(1) exFAT is only included with Vista and above.
|
|
For Windows XP SP2 and SP3 you need to download and install
|
|
the driver from http://support.microsoft.com/kb/955704/en-us
|
|
Windows XP SP1 and below do not support exFAT.
|
|
|
|
(2) UDF is only included with Vista and above.

!!! CAUTION !!!
|
|
|
|
If you select to format the volume make sure to not use a volume,
|
|
where you have valuable data stored else your data is lost.
|
|
|
|
It is best to use virtual test volumes without any existing data.
|

Setup:
|
|
|
|
1) Prepare separate volumes, 1GB in size with the disk management utility
|
|
|
|
2) assign a volume letter and any file system, so it can be found by the utility
|
|
|
|
a) You will be asked for the volume to process, which you select from the menu
|
|
|
|
b) If you format the volume you will be asked to select one of the supported file systems
|
|
|
|
3) CHKDSK is executed before and after the fragmented files creation process,
|
|
to make sure the volume is consistent.
|
|
|
|
4) It is best to always format the volume to always start with a fresh volume,
|
|
this will detect bad clusters.
|
|
In addition do only use volumes of 1GB in size, since quick format is not used, which
|
|
would only clear the file allocation table and would not detect bad clusters.
