Determining whether a data storage is encrypted
A method, program and/or system reads first data through a first path from a location in a data storage. Second data is read through a second path from the same location in the data storage. The first data is compared to the second data. A match between the first data and the second data indicates that the first path did not encrypt the first data. A mismatch between the first data and the second data indicates that the first path encrypted the first data.
1. A computerized system, comprising:
a means for storing data;
a means for reading a first data through a first path from a location in the means for storing data, wherein the first data was written through the first path to the location in the means for storing data;
a means for reading a second data through a second path from the location in the means for storing data;
a means for determining whether the first data matches the second data by comparing the first data to the second data; and
a means for determining whether the first path encrypted the first data;
wherein a match between the first data and the second data indicates that the first path did not encrypt the first data, and a mismatch between the first data and the second data indicates that the first path encrypted the first data.
2. The computerized system of claim 1 , wherein:
the first data and the second data are a same portion of a same file stored in the means for storing data.
3. The computerized system of claim 1 , further comprising:
a means for requesting a starting location of the first data in the means for storing data, the means for requesting the starting location using a device driver with access to the means for storing data;
wherein the means for reading the second data through the second path uses the starting location.
4. The computerized system of claim 3 , wherein:
the means for requesting the starting location uses system and defrag APIs to request a starting disk sector location of the first data.
5. The computerized system of claim 3 , wherein:
successfully receiving the starting location, upon a request by the means for requesting the starting location, indicates that the means for storing data is a physical volume.
6. The computerized system of claim 1 , further comprising:
a means for requesting a starting location of the first data in the means for storing data using a device driver with access to the means for storing data; and
a means for requesting a name of a device driver for the means for storing data when a request from the means for requesting the starting location to the means for storing data does not result in successfully receiving the starting location.
7. The computerized system of claim 6 , wherein:
not successfully receiving the starting location, upon the request from the means for requesting the starting location, indicates that the means for storing data is a virtual volume.
8. The computerized system of claim 1 , wherein:
the second path involves a device driver that bypasses an operating system file system driver.
9. The computerized system of claim 1 , wherein:
the first path involves an operating system call to the means for storing data.
