![]() However, unless the third-party software vendor consults with the drive vendor on correct SMART attributes, their definitions and thresholds (when applicable) are likely to mislabel the attributes and can lead to false-positive or false-negative failure reports. There are several third-party utilities that can retrieve and report a drive’s SMART data, often available in freeware and shareware. The attribute descriptors will vary between SSD and HDD, and even between the various SSD vendors. ![]() Unfortunately, regardless of the storage technology, there is no industry-wide standard to tell you which numbered SMART attribute describes a specific physical property of a drive. SMART was originally implemented on HDDs and was adapted for SSDs when this new technology was invented as a drop-in replacement for spinning hard drives. SMART has been around for many years and predates the birth of the SSD. The drive can only report if certain attributes have passed over pre-determined thresholds, and then only if thresholds have been programmed in firmware. SMART data can be a valuable tool, providing an early warning if a drive is having problems or has reached the end of its useful life, leading to the possibility of replacement before a failure.Įasy reporting to a user or system administrator is important because the drive itself is not capable of an in-depth analysis of the data. As the name suggests, it is a tool that records the health data of a hard drive disk (HDD) or a solid state drive (SSD). They had packed the drives in a very loose package and the hdd (although protected by bubble wraps) could easily move in the outer packaging.SMART stands for Self-Monitoring, Analysis and Reporting Technology. What the hell is going on?! This drive isn't even in use and reacts to what the other drive is doing? Because the sounds are on the right side of the laptop where I have the caddy installed. I know for sure that the noises come from the HDD. I must say that I have not even partitioned the HDD yet and I'm only using the SSD to write/read data (sth I didn't have in mind until now).Īnyway, I was installing Adobe Photoshop on the SSD and after 15% of the progress, the HDD started to make noises (about 10 times!) which is weird considering that I was working with SSD. And actually, something really weird happened right now. It cannot be a regular thing, 'cause it happens on specific occasions. You can use Bing or Google's calculator for hex/decimal conversion: Normal SATA SMART Attribute Behavior (Seagate): Seek Error Rate, Read Error Rate and Hardware ECC Recovered SMART attributes: In fact the actual number of seek errors is 0. The Read Error Rate and Seek Error Rate raw values are sector counts, not error counts. These correspond to the max, min and current temperature values for the current power cycle. Those look like 3 temperature values, namely 22C, 21C and 22C. I suspect that the upper 16 bits (or 20 bits) might be the fractional part of an hour, say milliseconds. The lower number is 0x20 which is 32 in decimal. They can consist of two or more values.įor example, Power On Hours appears to consist of two numbers: The raw values in many cases are not single values. I couldn't believe that someone would be able to make sense of hex values.
