Seagate 5TB Expansion Drive not initialized in MBR or GPT? Drive OK?

If you are running Seatools for Windows, when you select the drive to be tested you will get a menu of Basic Tests you can perform. One of those will be Smart Check. Do that check and see what it indicates.
Only that can be taken as authentic. ( Look out for the latest version of Seatools for Windows and specifically for your drive in the Support section.) You may also talk to their Tech Support, if you feel something is not right.

Thank you, jumanji,

Yes, I had done those tests already, any errors.

Only that can be taken as authentic.

Why is that? Other programs like ChrystalDisk, that Western Digital diagnostic program, HDDscan and so on are not reliable / good?

( Look out for the latest version of Seatools for Windows and specifically for your drive in the Support section.)

There was only one version for Win for all of the drives (not just for mine) of that program I could find. There are more than one? Cannot find another one.

Here the link I posted at the beginning of the thread of the SMART values of SeaTool:

You may also talk to their Tech Support, if you feel something is not right.

Yes, I already did, but no answers, since 1 or 2 days a message shows "maintenance", so I cannot post anymore. I have been there some months ago or so because of another drive, the same has happened. Appears to be pretty trashy that forum.

Thank you for the link, I will have a look at that manual.

Many thanks again

SMART is firmware that resides on the hard drive and continuously monitors drive parameters such as performance and error rates.Different drive manufacturers will have different S.M.A.R.T. specifications and thresholds as well.The specifics of these thresholds are not made publicly available. Therefore a third party software that can have only one common assumed criteria/threshold for drives manufactured by various manufacturers cannot be relied upon. It is as simple as that.

As long as your system does not report a SMART error as per the set standards and threshold you are OK. That is why I directed you to contact the Tech Support if you are overanxious.

Alright, so for each drive one should / must use the software of its manufacturer and not any other.

As long as your system does not report a SMART error as per the set standards and threshold you are OK.

The system? Means the OS? Or a program for a drive of the manufacturer? Well, there was that single error message shown above given by DriveInfo, that made me worry.

That is why I directed you to contact the Tech Support if you are overanxious.

Well, actually more like paranoid...over paranoid. Yes, a very good idea, of course, if only that Tech Support would be useful.

Thank you very much

Your communication to anything that is happening in your system is always through the OS.The smart check by the in-built firmware goes on inside your HDD all the time. The OS has no role in it. If the built-in firmware finds that some performance specification or threshold as set my the manufacturer exceeds the set limit, it notifies the OS and the messenger OS intimates it to you.

Rest in peace. ( not the other RIP. )

Alright, I understand.

Oops, I do not know another "rest in peace". Meaning my time has come now, to check in with the Almighty...that really does scare me a little bit.

Many thanks.
