Hi guys! I’ve been self hosting for a while and been using am 2 tb HDD I bought on aliexpress two years ago to host movies and series… I bought a second drive to separate them and organize my media.
For 2 months everything went awesome but suddenly I started getting IO errors from my old drive. specially when I download and watch a movie at the same time.
Is my drive going die or could it be something else?
Dmesg showed these messages
[345778.390949] sd 0:0:0:0: [sda] tag#23 access beyond end of device
I/O error, dev sda, sector 3833662344 op 0x0:(READ) flags 0x3000 phys_seg 1 prio class 2
The weird part is the sda device stops showing unless I turn the PC off and take the sata cables from it and restart the PC. Then I can watch movies for a while before getting this error again… Regular reboot does not work.


Well there’s the first red flag. Who’s it made by? Have you verified the capacity with one of those verifier tools? Fake ones will report a huge capacity while having very little, and writes past it just disappear. The error you’re seeing certainly sounds like that kind of behavior.
Yeah I suspected that too. Specially after downloading a lot of movies at once but I haven’t used any tools besides fsck and fdisk and they read 1.8 Tb…I’ll look into that to make surr… Thanks!
Use f3 tools
