SMART error each hour for a SSD, due to "unreadable (pending) sectors"
I have a laptop with a 1TB SSD. The smartd daemon logs an error each hour as follows: -=-=-=-> Device: /dev/sda [SAT], 1 Currently unreadable (pending) sectors Device info: CT1000MX500SSD4, S/N:2027E2B39329, WWN:5-00a075-1e2b39329, FW:M3CR023, 1.00 TB For details see host's SYSLOG. -=-=-=-> When I run: sudo smartctl /dev/sda -a I get a lot of information which I do not understand its implications. However, the device has SMART capability but it is not in smartctl database and: -=-=-=-> SMART overall-health self-assessment test result: PASSED -=-=-=-> When I run: sudo egrep /dev/sda /var/log/syslog I get: -=-=-=-> May 4 00:02:36 c5 smartd[1014]: Device: /dev/sda [SAT], No more currently unreadable (pending) sectors, warning condition reset after 1 email May 4 00:02:36 c5 smartd[1014]: Device: /dev/sda [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 56 to 62 May 4 00:32:36 c5 smartd[1014]: Device: /dev/sda [SAT], 1 Currently unreadable (pending) sectors May 4 00:32:36 c5 smartd[1014]: Device: /dev/sda [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 62 to 59 May 4 01:02:36 c5 smartd[1014]: Device: /dev/sda [SAT], No more Currently unreadable (pending) sectors, warning condition reset after 1 email May 4 01:02:36 c5 smartd[1014]: Device: /dev/sda [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 59 to 64 May 4 01:32:37 c5 smartd[1014]: Device: /dev/sda [SAT], 1 Currently unreadable (pending) sectors May 4 01:32:37 c5 smartd[1014]: Device: /dev/sda [SAT], SMART Usage Attribute: 194 Temperature_Celsius changed from 64 to 59 -=-=-=-> and the above repeats each hour. The laptop seems to work OK with no data loss or such. However I'd like to understand what is going on and if possible how to get rid of the warnings. One more fact which may have bearing: few months ago, had the laptop's 256GB SSD replaced by a 1TB SSD. Any suggestions how can I troubleshoot it? Any additional information I should look at?

odd alert nvme error "The transport type is not indicated or the error is not transport related"
Hi, I'm struggling to get what could mean this odd "The transport type is not indicated or the error is not transport related" error inside nvme error-log which is filling my error log. I also get smart warning of increasing num_err_log_entries , it look like it could correspond to one error for each boot but I do not grasp what could that mean. I don't see any noticeable problems for now other than this alert. output form error-log have errors like this : sudo nvme error-log /dev/nvme0 .
