Dell R640 and Seagate Exos ST2000NX0253 Drives

We have a R640 with a Dell PERC740P mini Controller.

Currently we have a raid 5 array using 2Tb ST2000NX0423 Seagate Drives (official Dell fw NB33)

I wanted to add to this by adding a new 2TB drive to act as a hot spare. 

I have added a brand new 2Tb ST2000NX0253 Seagate exos drive and from what i can see the spec is identical to the existing drives however the controller refuses to allow it and keeps marking it as failed, I have tried the change to the stsvc.ini file as this is a non certified drive but no joy, Is there an issue here I'm missing or have i just got a Dud drive.

The PERCH740P Mini is on fw : 51.16.0-5150

BIOS 2.19.1


Existing Drives 2Tb ST2000NX0423 fw:NB33

New Drive 2Tb ST2000NX0253 fw:SN05

Hello Stuart,


Non-certified just means it's not a Dell drive. Typically it could work if it is the same technology and capacity but because it a non-Dell drive, it may not work. Dell doesn't guarantee it to work.


You indicated it is marked failed.

Try running the built in diagnostics and check results.

Boot to  F11 on Dell Splash screen, selecting  Boot Manager -> System Utilities -> Launch Dell Diagnostics.  Note any messages and continue testing.


Also take a review of the LifeCycle Controller (LCC) log <F10> on boot up to enter the LCC. Do you see any errors or faults for drives?


You may want to try to get identical drive as existing drive, if possible.
