Hello there, I have a: Samsung HM321HI (apparently same as Spinpoint M7E 320Gb ST320LM000) fw 2AJ10001 which was ok until I put it on a machine (for backing it up) with a faulty SATA power cable which caused a write failure. Drive signaled End-To-End SMART error after that, although it works fine and passes read tests.
I DL firmwares from here but has no tool to upload them to the drive. I do have a serial TTL to usb adapter if needed.
Is there a way to reset SMART attributes so BIOS and windows stops asking to replace the incorrectly flagged faulty drive?

Here's Smart log:

Thanks, will try to do that (if I can find SRT), it's annoying to know that drive failed due to bad cable and SMART not being so "smart" to acknowledge problem is gone.

s.m.a.r.t only predict failure.
there is different opinion among professional about s.m.a.r.t, yet the ability to predict failure is almost accurate.

Yes unfortunately sometimes it's data might get corrupt as happened because of false contact on power cable. I had just received a Fujitsu drive whose raw Smart Power on time is in seconds instead of Hours. I wonder if Smart fields are updated every second and where that data is stored (normal flash memory has a limited amount of write operations)...

Greetings,
The S.M.A.R.T. Tables are stored on the platters on the service area !

In that case, this Fujitsu drive writes smaart powerontime once per second, it probably will overuse that area, besides it might slighly affect drive performance (moving heads outside working zone every second), although it's probably neglectable.
What happens if smaart area becomes bad?

If it is well designed it's probably like that.
Could you please answer my post (about SRT) on the other forum (hddoracle)? Thanks!
