Thanks.

P/S The drive used to work in good conditions exclusively on seldom and light reading operations. One day it started making this noice and has no detected in bios/os.

PP/S In fact i had five drives the same model all of them have failed withing two years, All of them was bought in China.

Hello,

You get such spikes where the LBA region is not allocated by T2. Drive does not read from surface there, only sends empty sectors to the host. This is done much faster than it can read from the surface, you see that there.

What I find strange is that there is no sign of serpentine zones, which suggests that all 40GB is being read from a single head, or that all heads are set to the same BPI.

On smr drives head zones are very large.
Head map bulding in DE doesn't work as usual cmr drives, on smr head map is based on module 190.

two question - what is T2, second - are you saying that everything is working as intended?

T2: Second level translator
SMR drives need this type of dynamic translator which is included in module 190

thanks!

thanks for try but not really helping

just please tell me if SMR disks are good for data storage in long term? with bearing in mind of extremely seldom write operations.

is there other reason i should get rid of all my SMR drives?

i like they are cold, silent and with low wattage
