Introduction
Our Storage Device Viewer applet allows you to send a few Command Descriptor Blocks (CDBs) to your storage device. The return data is graphically decoded for you. You can download it here.

We allow the following commands to be sent:

• Device Inquiry
• Inquiry - Supported VPD Pages (Vital Product Data)
• Log Sense - Supported Log Pages
• Log Sense - Device Temperature

Please note that some of these commands are only supported by high-end storage devices such as SAS, Fibre, iSCSI, and others.

This application does require that you "activate" the software prior to use. Activation occurs only after you allow the program to upload information about your storage devices to our web server. The information you provide will help us to keep our CDB decoding engine up-to-date, look for additional firmware bugs, and more. NO PERSONALLY IDENTIFIABLE INFORMATION IS RECORDED.

When you run storinfo.exe, you select your storage device in the available "Select Device:" drop-down list. You then select the CDB you want to send from the "Send Command:" drop-down list. Once you do that, the CDB is immediately sent and the results are shown to you.

This program only allows you to submit a handful of CDB requests. Our retail product, busTRACE 8.0, allows you to submit any CDB to your storage devices.

Below you will find sample screenshots of return data from a Hitachi SAS hard drive.

First we start with an Inquiry CDB. As you see in the screenshot below, we decode the command going out to the device and the data returned from the device.

Next we issue an Inquiry CDB - Supported VPD Pages. Here we see the Vital Product Data pages that the Hitachi drive supports:

• Supported VPD Pages
• ASCII Information
• Unit Serial Number
• Device Identification
• Extended INQUIRY Data
• Mode Page Policy
• SCSI Ports
• Hitachi Ultrastar Page D1h
• Hitachi Ultrastar Page D2h

Next we issue a Log Sense CDB - Supported Log Pages. Here we see the log pages that the Hitachi drive supports:

• Supported Log Pages
• Write Error Counter
• Read Error Counter
• Verify Error Counter
• Non-Medium Error
• Temperature
• Start-Stop Cycle Counter
• Application Client
• Self-Test Results
• Background Scan Results
• Protocol Specific Port
• Informational Exceptions
• Hitachi Performance Counters
• Hitachi Counters

Lastly, we issue a Log Sense CDB - Device Temperature. We see that the drive is running at 46 degrees Celsius or 114.8 degrees Fahrenheit.
