last summer I replaced my faulty 2TB system drive with a combo of a 250GB SSD (for the OS) and another 2TB HDD (for those large video files, games and stuff). Back then the drive started to behaved strangely, like video playback stuttering, checksums on single files failing and eventually refusing to boot altogether. Now imagine my shock, when yesterday, I noticed stuttering on video playback again (I do a lot of video related stuff on my mint system) and after a quick check with gnome-disks it tells me, that this time my SSD has bad blocks:
What really scares me, that when I first noticed, it was one bad sector. Then I started backing up data, it turned to two, and this morning it's 4 already. What is strange though: all the videos that made me notice this in the first place are stored on the HDD (which is okay, according to gnome-disks) and not on the SSD. Maybe it's because the swap partition and the operating system is on the SSD? A badblocks read test also didn't show any errors:Model:ADATA SU800 (P1021A)
Size:256 GB (256.060.514.304 bytes)
Partitioning:Master Boot Record
Serial Number:2H0720015298
Assessment: Disk is OK, 4 bad sectors (32° C / 90° F)
And smartctl also doesn't seem to show anything unusual:badblocks -s /dev/sda
Checking for bad blocks (read-only test): 87.10% done, 10:00 elapsed. (0/0/0 errors)
done
Is there any way to get more information, to make sure it's the SSD that's failing and not the HDD?[smartctl -a /dev/sda
