*
* In full mode, the program writes a test pattern on the entire disk.
* The test pattern (device offset and timestamp) is written at the
* beginning of each 4kB block. When the whole device is full the read
* operation is performed to verify that the test pattern is correct.
*
- * In fast mode, the program writes data at the critical locations
+ * In partial mode, the program writes data at the critical locations
* of the device such as start of the device, before and after multiple of 1GB
* offset and at the end.
