Hello,
after buying two Seagate Ironwolf 2TB last week, i installed them in my NAS this weekend.
While running a SMART-Selftest for he two new drives there were two logs-entries, that inform me about an increase of the RAW_Read_Error-Rate-Value from 100 to 117, and then from 117 to 120 for one of the drives.
The status of both drives is instantly green and the Test-Status of the Extended-Offline-Test was „completed without errors“.
Under „More Information“ fort he mentioned drive i found this:
The other drive – for which no notification in the logs was found – looks like this:
Until now i thought, that the SMART-Value starts with 100 (in some cases 200 or 255) an gets smaller, when errors occur. After falling under the „Threshold“-Value an SMART-Alert starts.
That a value gets higher was new to me. Does somebody know this from his / her own NAS-Drives? Eventually the values were wrong interpreted by smartctl and my drive has problems / is defect? The RAW-Value of the RAW_Read_Error-Rate is significant higher for the first drive - but does this mean, that there is a problem with the the harddisk?
Thank you for your answers and nice greetings,
Chris
