Intel 540s periodic refresh blocks broken?

ssd have old partitions and old files around 4-5 years old on them. These partitions have enough free space (spare blocks, never touched). I tried ddrescue on these partitions&files, the reading's speed was very slow compared to another fresh partitions, 33mb/sec average with often drops to 0. Some files had badblocks around some tens.

Smart values:

E9 - 100%

F9 - 3.5Tb on 1tb ssd

Spare blocks - 100-300Gb were never used.

My questions:

1) Why didn't the firmware refresh degraded blocks on such huge period?

2) What does mean huge smart BB counter with thousands value after reading old partition? I have badblocks, but not so much. Are the data still consistent with exception known badblocks?

3) Why didn't the firmware refresh degraded blocks after 5+times readings in row?

4) Is it warranty case?

Hello, andrey_v1.


Thank you for contacting Intel® Memory and Storage support.


As we understand, you need assistance with your Intel® SSD 540s Series. If we inferred correctly, we would appreciate it if you provide us with the following information:


1- We would appreciate it if you can provide us with the system details by extracting the SSU logs.


A- Go to https://downloadcenter.intel.com/download/25293/ (for Windows*) and to https://downloadcenter.intel.com/download/26735/ (for Linux) download the software.

B- When you finish downloading it, open it.

C- Attach the file generated by the tool in your reply.


2- We would like to check the SMART attributes of your Intel® SSDs and review them to see if they show any error, using this system or another system that recognize the drives:


*Please extract the following logs by using the Intel® Memory and Storage Tool:

The statement about firmware is a lie. It contains OPTIMIZATION, not BUG FIXED.

My questions still the same:

 

Spoiler

1) Why didn't the firmware refresh degraded blocks on such huge period?

2) What does mean huge smart BB counter with thousands value after reading old partition? I have badblocks, but not so much. Are the data still consistent with exception known badblocks?

3) Why didn't the firmware refresh degraded blocks after 5+times readings in row?

4) Is it warranty case?

 

But actually they are the statements. My position:

You have an old device model(s) with undiscovered Refresh Period bug due to firmware update descriptions. My host was powered everyday, with some breaks, to do enough reprogramming stuff in background. Firmware algo even didn't try to refresh blocks after slow read.

Also, i  noticed, that 09 counter contains 500hrs, but should contain  10000-16000hrs. Your firmware even have overflow bug on simple counter. I guess on 16384 value.

I am asking you:

0) To invite proper engineer or team

2) To investigate the problem with refresh period and poweron counter.

( It's interesting case, this device (and all others loyd stars) is under expiring warranty period and has such a longplay bug. And the old information on it is close to death. And i don't understand how to use it in future without autorefreshing blocks (or trust into working autorefreshing ) Probably, it's not warranty case. But i've  bought it  because of 5years warranty period and now wanna to get a good customer service.  )

3) to extend warranty period for a problem device with low usage PE blocks (or better solution).
