Hello Bruce!

Thank you for your answer! As Christian Franke (Thanks) already 
suggested I shortly asked Seagate and got this answer:

"Dear Robert Gruber:

Thank you for contacting Seagate Support. From your email, we understand 
that you would like to know about the SMART values from the third-party 
utility 'smartmontools'. We will be glad to assist you with this.

Please note that third-party diagnostic tool test results may not 
reliable for Seagate drives and the SMART values that might be read out 
by third-party SMART software are not based on how the values may be 
used within the Seagate hard drives. Seagate does not provide support 
for software programs that claim to read individual SMART attributes and 

In this instance, we suggest that you run the SMART test using Seatools 
for DOS and provide us report whether it has not been tripped or 
tripped. SeaTools for DOS is a bootable version. You should burn the 
SeaTools.ISO onto a CD.

SeaTools for DOS - Knowledge article:


Note: The Fix All long and Fix All Fast attempts to repair any problem 
unreadable LBAs (sectors) it might detect. It is important to know that 
when the sector is bad and unreadable, any data in it is already lost. 
As an advisory statement, we would like to inform you that repairing the 
disk, deleting, erasing, formatting, or partitioning your drive will 
permanently delete the data (pictures, videos, music, and documents),and 
Seagate may not be able to recover it without it incurring a cost.

Please get back to us with the SeaTools for DOS SMART test results, 
based on which we will analyze and assist you further. Awaiting for your 
response at the earliest.

Please reply to this email if you require further assistance.

Seagate Support"

Probably I should ask HGST ;-)
