File System Driver Test for Flash (Compact 7)
3/12/2014
The File System Driver Test is designed to uncover problems with a file system driver (FSD) that uses the Win32 application programming interface (API). You can use this test to find problems with a storage device block driver that runs under the file allocation table (FAT) FSD. You can also test a custom FSD.

5022 |
Attempts to create more than 999 files with the same file name extension and the same first eight characters in the file name. This test fails if it creates more than 999 files or creates fewer than 999 files. If this test fails on a volume that is not a FAT volume, failure does not necessarily indicate that the implementation of the file system is faulty. This test will automatically be skipped on any media formatted as ExFAT or TexFAT. |
5023 |
Creates a 100-byte file on a volume that has only two clusters available. This test fails if it cannot create the 100-byte file. If this test fails on a volume that is not a FAT volume, failure does not necessarily indicate that the implementation of the file system is faulty. |
5024 |
Creates a directory on a volume that has only one cluster available. This test fails if it cannot create the directory. If this test fails on a volume that is not a FAT volume, failure does not necessarily indicate that the implementation of the file system is faulty. This test will automatically be skipped on any media formatted as TexFAT. |
5025 |
Creates a 100-byte file on a volume that has only one cluster available. This test fails if it cannot create the 100-byte file. If this test fails on a volume that is not a FAT volume, failure does not necessarily indicate that the implementation of the file system is faulty. This test will automatically be skipped on any media formatted as TexFAT. |
5026 |
Creates directories on a volume that has only one cluster available. This test fails if it cannot create at least one directory. If this test fails on a volume that is not a FAT volume, failure does not necessarily indicate that the implementation of the file system is faulty. |
5027 |
Attempts to create a directory on a volume that has no clusters available. This test fails if it successfully creates a directory. If this test fails on a volume that is not a FAT volume, failure does not necessarily indicate that the implementation of the file system is faulty. This test will automatically be skipped on any media formatted as TexFAT. |
5028 |
Attempts to create an empty file on a volume that has no clusters available. This test fails if it cannot create an empty file. If this test fails on a volume that is not a FAT volume, failure does not necessarily indicate that the implementation of the file system is faulty. |
5029 |
Attempts to create a 100-byte file on a volume that has no clusters available. This test fails if it successfully creates a 100-byte file. If this test fails on a volume that is not a FAT volume, failure does not necessarily indicate that the implementation of the file system is faulty. |
5030 |
Attempts to write a file using the WriteFileWithSeek function, if the function is supported by the file system, when there is only one cluster available on the drive. This test fails if the WriteFileWithSeek function writes no data to the file. If this test fails on a volume that is not a FAT volume, failure does not necessarily indicate that the implementation of the file system is faulty. |
5031 |
Writes data to and reads data from the volume using the WriteFileWithSeek and ReadFileWithSeek functions. This test fails if the data written does not match the data read. This test is skipped if the file system does not support these operations. |
5032 |
Attempts to move a directory that contains a file with an open file handle. This test fails if the directory move does not succeed or if the file handle cannot be closed after the move completes. |
8001 |
Creates, writes, reads, and verifies files in multiple directories using a separate thread for each directory. This test fails if it cannot create, write to, or read from a file using multiple threads. |
9001 |
Formats each partition of the specified storage profile. This test fails if it cannot format a FAT partition or if Fatutil.dll is not available. This test does not format volumes that are not FAT volumes and automatically passes. |
Setting Up the Test
To run the default command line, the flash file system in the platform must use the "FlashDisk" profile name. If another profile name is used on your device under test, please update the command line to use the new profile name.
The onboard flash memory can be partitioned and formatted using the Storage Manager Control Panel Applet. This applet can be added to the image using the SYSGEN_STOREMGR_CPL. After the image has been built, the Storage manager applet can be accessed by My Device->Control Panel->Storage Manager.
Running the Test
The following table shows the command line parameters for the File System Driver Test.
Syntax:
tux -o -d fsdtst -c "[-p PROFILE] [-s FILESYSTEM.DLL] [-r PATH] [-c clusterbytes] [-d maxrootdirs] -q -f"
| Command line parameter | Description |
|---|---|
-zorch |
Runs all test cases, destroying all information on the storage device. Test cases write to and read from sectors on the storage device without preserving the contents of the sectors. |
-p <profile> |
Specifies the storage profile to which to restrict testing, found in the registry under the HKEY_LOCAL_MACHINE\System\StorageManager\Profiles key. |
-s <filesystem> |
Specifies the file system to which to restrict testing. The default file system is Fatfs.dll. You only need to specify a file system when testing a new FSD. |
-r <\root> |
Specifies the root directory in which to run the test. If you provide this option, the test only runs in the specified directory and ignores the -s and -p options. This flag is useful for a file system driver that does not use storage profiles such as a network file system driver. If the name of the root directory includes spaces, surround the name of the directory with single quotation marks; for example, -r '\Storage Card'. |
-c <clusterbytes> |
Specifies the size of a cluster used by the FSD. You can use this option to specify the size of a cluster for a file system that is not a FAT file system. Specifying this option does not affect the cluster size for a FAT volume. By default, the test uses a cluster size of 4096 bytes. You can use the default value if the file system being tested does not have a cluster-like data structure. |
-d <maxrootdirs> |
Specifies the maximum number of directory entries that the test attempts to create in the root directory. Specifying this option does not affect the number of directory entries for a FAT volume. The default value is 255 directory entries. You can use the default value if the file system being tested does not limit the number of directory entries that can exist in the root directory. |
-q |
Disables quick filling of partitions. Quick filling is enabled by default and, for a test case that requires the creation of a large file to fill the partition, a large filler file is artificially created by calling the SetFilePointer and SetEndOfFile functions. If you specify this option, disabling quick filling, a large file is created by repeated calls to the WriteFile function. |
-f |
Disables automatic formatting of each mounted partition before testing. Automatic formatting is enabled by default and each mounted partition is formatted as a FAT volume before each test case runs. If you specify this option, the test does not automatically format each mounted partition. If this flag is used, it should always come at the end of the command line; otherwise, the command line will not parse correctly. |
Verifying the Test
When the test completes running, verify that "PASS" appears in the test log for all sub-tests.
Troubleshooting the Test
* Make sure that the profile name in the command line after the -c is correct. If your device is not using "FlashDisk" for the flash file system, please update the command line with the name of the profile your device is using.
