The interval for replacement depends greatly on the type of use. A specific interval cannot be
given.
All drives are monitored with the software tools DiagBase or DiagMonitor on the basis of
their SMART status. As soon the SMART status of the HDD or SSD switches to "Not OK", a
message is sent in DiagBase or DiagMonitor, or when you start up the PC. You should then
back up your data and replace the drive.
