The most common issues that this function identifies are:
- Power circuit failure, such as a failed fuse or power converter chipset
- Motor seizure or heads sticking to disk platters, for example, a mechanical issue preventing the drive from spinning up
The function also identifies some other failures, such as a failed motor controller chipset or a failed CPU. However, identifying these failures may require some expertise. You must compare graphs taken from a failed drive with graphs from a good drive of the same family, because the lower level diagnostic is drive-specific.
In general, taking into account the fact that most 3.5” drives consume 5V for CPU and voice coil actuator operation and 12V for motor-related circuitries, it is possible to identify an area of the drive where the problem lies. Since all 2.5” drives consume 5V only, their diagnostic is a bit less functional; however, common issues such as the two failures mentioned above are still easily identified.
The hardware package for DeepSpar Disk Imager is sold separately either with a purchase of a new DeepSpar Disk Imager or as an add-on to your existing DeepSpar Disk Imager. You will need to solder a mini printed circuit board to the main printed circuit board inside DeepSpar Disk Imager’s enclosure. It also requires upgrading DeepSpar Disk Imager’s firmware using its USB port.
