What does the smart Program_Fail_Count_Chip attribute mean and what should its value be?

Question

Solid State Drives

Hi friends!
smartctl -a /dev/sdbproduces the following:

The line worries my soul:

175 Program_Fail_Count_Chip 0x0033   100   100   010    Pre-fail  Always       -       17190814348

I would be grateful for any comments, including useful links.

Answer 1

This parameter indicates the number of failed attempts to write to the drive's internal flash memory. That is, either the entry in the SMART itself was failing, or firmware errors.
Most likely, this is some kind of glitch visible as an overflow, or somehow a sign value got there ...
In general, it depends on the drive model. Sometimes this parameter is increased when the blocks are not aligned to the 4k border, or have a size other than 4k.

Answer 2

Although the question is more than a year old,
most likely the disk is not in the smartctl database (and this is clearly written in the missing header). All of these fields are vendor specific, and often model specific. At the same time, there are certain fields that are standard for all manufacturers - you can see them like this:
smartctl -l devstat /dev/
sdb Their field 175 means something completely different. Learn more - https://communities.intel.com/message/286989
