Questions[smart](ubuntu)

Installed Smartmontools, I'm able to get disk info with smartctl, but I can't get smartd to work.

When I run smartd -q onecheck, I get:

smartd 7.4 2023-08-01 r5530 [x86_64-linux-6.8.0-53-generic] (local build)
Copyright (C) 2002-23, Bruce Allen, Christian Franke, www.smartmontools.org

Opened configuration file /etc/smartd.conf
Configuration file /etc/smartd.conf parsed.
Device: /dev/sda [SAT], open() failed: Permission denied
Device: /dev/sda, not available
Unable to monitor any SMART enabled devices. Exiting.
smartd is exiting (exit status 17) 

My laptop SSD is acting up and the number of errors soared since the last time I posted.

Is this drive dead / dying?
It's on now and I'm writing this on it - I have all my data backed up and all, but I am still unsure if it's usable or not?

Contacting the manufacturer didn't help much: they asked me to install Windows and run the disk check utility from there or connect it as an external drive to a Windows host and test it there.
I did both and no errors were encountered.

I also checked it with the utility they provide (see screenshot below). I then used the image I made with clonezilla to return to Ubuntu, and I found that the SATA PHY error count is nearing 300 errors!

I've also checked the connectors, but since the SSD is in a laptop I cannot change the cable (easily).

These are the test results generated by the manufacturer's utility

And the smartctl output on Ubuntu, later:

I have a year-old drive that's giving me trouble. Copying data to it fails after about 8-10GB of transfers. It spontaneously changes to 'read only'. It's properly formatted ext4, I'm the owner. Searching online, it looks like this is a symptom of a failing drive.

How do I confirm this, since the SMART tests indicate otherwise?

I did the obvious like check the Disk Utility, and ran the extended SMART test. All results from Disk Utility come back perfect. Read error rate and reallocated sectors are showing zero.

I'm guessing this disk is bad and SMART isn't detecting it, though I don't understand why. I'd like to confirm what the problem is.

I'm having no problems with the other disks in the machine.

Last but not least is the read/write screengrab, this is new. It used to stay pretty consistent over the duration of the test.

EDIT- When I powered on this morning the drive had changed from /dev/sda to /dev/sdc, strange. I'm certain that hasn't happened before and I'm certain it was /dev/sda. I swapped SATA cables with a known good one and saw that same failure at about 10GB transfers. I didn't change SATA ports yet, I'll try that next. (Edit #2, it was the SATA port, changing it fixed the problem. Flagging this as too localized.)

I'm getting these errors ramdomly, and I don't know if its normal or not.

I'm also pasting smartctl -a for sda, sdb and sdc.

Thanks in advance for your help.

Whenever I start my computer Ubuntu pops up the following error:

A hard disk may be failing
one or more hard disk report health problems

A friend of mine ran some test and it was found that my hard disk has 74 bad sectors.

Is this merely a software issue that will be solved after a complete format of my hard disk, or is it a hardware issue and I will have to replace my hard disk?

Awaiting your responses.

Thanks,
Sneha Kamath.
