To view media statistics

1. On the navigation bar, click Media.

2. Expand the All Media icon, and then select the media that you want to view.

3. Under General Tasks in the task pane, click Properties.

4. Select the Statistics tab.

   The Statistics tab provides the following information:

   Hours in use	The total number of hours that this media has been in use.
   Used capacity	The amount of raw capacity on the media that has been used. Used Capacity is calculated by subtracting Available Capacity from Total Capacity. Used Capacity may or may not equal Bytes Written.
   Available capacity	The amount of expected raw capacity on the media that remains unused. Some tape devices support the ability to read the amount of remaining capacity of the media that is currently loaded in the device. If a tape device supports reading of the remaining capacity amount, then Available Capacity is derived from the remaining capacity amount. Otherwise, Available Capacity is calculated by subtracting Bytes Written from Total Capacity. Because Free Space is reported in terms of unused raw capacity, review Bytes Written and Compression Ratio to better estimate if there is enough free space to accommodate a specific job.
   Total capacity	The amount of expected total raw capacity of the media. Some tape devices support the ability to read the amount of total capacity of the media that is currently loaded in the device. If a tape device supports reading of the total capacity amount, then Total Capacity is derived from the total capacity amount. Otherwise, Total Capacity is estimated based on past usage of the media.
   Compression ratio	The ratio of Bytes Written to Used Capacity. Compression ratio will show the overall effect that data compression and media flaws are having on the amount of data that is being stored on the media.
   Bytes written	The amount of data that has been written into blocks on the media. Bytes Written may differ from Used Capacity due to the effects of data compression and media flaws. Data compression will tend to increase Bytes Written when compared to Used Capacity. Media flaws will decrease Bytes Written when compared to Used Capacity.
   Bytes read	Number of bytes that have been read from this media.
   Mounts	Number of times this media has been mounted.
   Seeks	The total number of seek operations (performed when a specific piece of information is being located) that have been performed on this media.
   Seek errors	The number of errors encountered while trying to locate data.
   Soft write errors	The number of recoverable write errors encountered. If you receive soft errors, it may indicate the beginning of a problem. If you receive excessive errors for your environment, check the media for damage.
   Hard write errors	The number of unrecoverable write errors encountered. If you receive hard errors, check the media for damage.
   Soft read errors	The number of recoverable read errors encountered. If you receive soft errors, it may indicate the beginning of a problem. If you receive excessive errors for your environment, check the media for damage.
   Hard read errors	The number of unrecoverable read errors encountered. If you receive hard errors, check the media for damage.
