I did a quick experiment this week in the lab. I had a Toshiba 80GB SATA hard drive that was showing signs of failure. I wasn’t able to install windows on the disk. I ran a HDDScan on the drive and collected the data (Fig 1-1 below) and then I ran Spinrite software on the drive in “Deep Scan Maintenance Mode” on the affected hard drive. The maintenance scan took nearly 14 hours to complete. Afterwards, I ran the SMART test feature of HDDScan again and recorded the details. (Fig 1-2)
As you can see, the empirical data is nearly the same. There is not enough data to determine whether or not Spinrite can be considered a drive repair tool in this case. More tests will be required. Subscribe to follow this experiment as we adjust variables and re-test.
