Hey guys i noticed some data corruption errors on my cache drive but logs were not showing which files got corrupted, so i ran a scrub test on my cache drive but scrub didn't find any data corruption.

 

So is there any way to find out which files got corrupted.

Start by running memtest, then also need to scrub disk1 since there's a lot of corruption detected there.

@JorgeB could those corruption errors caused due to ATA Link errors cause the thing is from like past month or so i was getting ATA link errors on disk 1 but i had been quite busy with work so i never got around fixing that until last sunday but then by then it had already started showing disk read errors and corruption errors so after some reseating/interchange came to conclusion that it was bad sata power splitter. And after i replaced it those read and corruption warnings were gone so i thought maybe because   of bad sata power splitter it wasn't able to read properly maybe thats why it was showing corruption errors too. I just now realized that its still showing corruption, its just that now its under normal text instead of warning or text.

Unlikely but possible, especially if there's a bad firmware.

Clear the errors and keep monitoring.
