SOLVED - how to ID if my hard drive is using SMR or PMR Technology


Recommended Posts

I am looking at purchasing some large TB's hard drivers, but then I read up on the specs a lot of them don't mention SMR, CMR or PMR.  

 

I have seen the following on Amazon - 

 

Seagate Enterprise Capacity v6 10TB Internal Hard Drive ST10000NM0046 SATA 3.5" HDD 256MB Cache

 

MDD - HGST He10 (HUH721010ALE601) 10TB 7200RPM 128MB Cache SATA 6.0Gb/s 3.5inch Enterprise Hard Drive (Renewed)

 

I have google around and found that you can find out via the Smart data of the hard drive, but running smartctl, so as a test I have ran this on one of my old 10 TB hard drivers, below is the test.

 

I have looked through and I can't see anything that talks about the technology,   can someone please point to the right location

The info isn't reported by smart itself, but if smartctl knows about it in its database it'll be mentioned next to the model on top. In this case 

 

Quote

Device is: Not in smartctl database 7.3/5577

so it doesn't know. 

 

Best is to check the manufacturer's specs/lists or actual drive datasheets, e.g. for Seagate https://www.seagate.com/products/cmr-smr-list/

 

There are also user-contributed lists around.
