Summary0002075: Plextor SSD SMART temperature attribute not recognised
DescriptionI run an Asus U41JF laptop.

Its HDD was a Seagate 640GB, which had no problems being recognised in SpeedFan. SMART data and temperature were also recognised and reported by SpeedFan.

Recently I replaced the Seagate with a Plextor M5Pro 256GB SSD (PX-256M5). Now SpeedFan detects the SSD brand and model but then labels is as a "SCSI" drive.

Additionally, an error is immediately reported in the scanning window after that: "ProbeSCSI: WARNING: hard disk skipped because of invalid returned LogSense data". SMART data from the SSD can be read and is displayed, but no temperature data could be obtained. Temperature also does not appear in the list of Attributes in the SMART tab (but other attributes are).

Interestingly, even though my Seagate HDD is now in a USB 2.0 external enclosure, it is correctly detected by SpeedFan and temperature (as well as other SMART data) are recognised and displayed.

Could this be due to the SSD storing the temperature attribute at a different address/location in SMART?
Steps To ReproduceEvery run of the application.
TagsNo tags attached.

The warning message about SCSI is caused by some partial support for SCSI calls. It's not a real issue in your case, because other calls work fine and, in fact, you can see SMART data.
Are you sure that your SSD can report its temperature? Several do not.
