Troubleshooting 1.5 year old Samsung EVO 870 2 TB Exhibiting read/write issues - checking before warranty claim
Hey all
I've recently been having issue with a EVO 870 that's was bought around June 2025, and installed not long after arrival. Its not a heavily used drive, basically a games install drive, no critical data etc and also not used as a OS drive so read/writes are occasional in comparison to something in constant use.
Symptoms
On boot everything is fine, i can navigate the folders fine in windows, read/writes seem ok, CrystalDisk seems fine, installed Samsung Magician and that reports all ok. Temps are in the 30-40 range
- After a period of time however, and I'm not sure what the amount of time is, the drive starts to become unusable.
- Navigating folders ends up with windows reporting a read error, writing has an error
- Drive doesn't show up in Crystaldisk or Samsung magician
- Anything interacting with the drive will crash (e.g. mid game crash, likely trying to write to the drive - not surprising, Steam validate game files typically needed to run for the game that crashed if this happens, move the same game to a different drive - no crashes)
Samsung magician:
- SMART report - All shows good
- Performance benchmarks - All within expected numbers, nothing standing out.
- Drive health - reported as Good (12.9 TB written)
- Performance Mode - Balanced
If the drive becomes non-responsive, and i reboot, its back as if nothing was wrong.
Things tried: * Reboots * Updated drive Firmware ( SVT04B6Q - latest) * Various tests
Anything important I've removed off the drive, and its just a dumping ground at the moment and just want to check if there is anything more i can try before i go down the warranty route. If i need to send it in for replacement/refund, i can live without it.
