Samsung 512GB 840 pro issues

[jimjam81]

Hi

I have had this SSD for almost 3 years as an Steam gaming drive on my various PC's.

Last night my X99 based system with Windows 10 would not boot up the OS. Windows would just hang with the logo and spinning dots.

As soon as I unplugged the 840 pro from the Motherboard Windows 10 would boot up fine from the primary drive (Samsung 850 Evo).

If I plugged in the 840 Pro again the same error would occur and the bios would not pick it up and Windows 10 would refuse to boot from the 850 Evo drive its installed on.

This morning I took my Crucial 512GB SSD gaming drive from my laptop (P35x) hot swappable bay and put in the 840 pro SSD.

The same error occurred and Windows 10 refused to boot on my laptop from the Micro Raid SSD that came with it, the same error as above with Windows logo and spinning circle.

However the laptop bios did detect the 840 pro drive but only detected it as 0.9GB in size.

I swapped the SSD back out for the Crucial on the laptop and Windows 10 booted just fine with the Crucial SSD detected.

So I am coming to the conclusion that my 840 pro is knackered. I have got one more test to do which is try on my original Windows 7 PC just to rule at minor possibility of Windows 10 issue.

I just want to know if anyone else has had similar issues with secondary drives causing Windows 10 failure to load up. I don't quite understand as Windows 10 is installed on a sound drive but still fails to boot when this secondary drive is plugged into the motherboard.

I think the 840 Pro warranty is 5 years but I am loathed to send it back due personal data on the SSD.

Are there any other tests I can do? Would it be possible for me to get the data off this drive?

Thanks

Jim

Have you got it set up correctly in the bios? UEFI or AHCI?

Hi, thanks for the reply.

I am pretty sure it was UEFI and I also sure now the drive is dead

I managed to get the Windows 7 machine bios to eventually detect and more importantly boot into Windows without freezing. (took a little while with changing cables and such for bios to pick up both drives)

As soon as Windows 7 boot up it said installing driver for disk drive ( note it was previously installed on this machine and Windows 7 has not been re-installed in the interim)

I then went computer management and storage to check the drive out and it detected it 0.9GB of space left. It could also not wipe over it or install NTFS on it. I could practically do nothing with it.

Samsung magician detected the drive but had a big red X next to it, and a lot of broken text characters for the name of the drive. I have a screenshot of this.

I installed the latest version of magician and it detected the drive but did not recognise it as a Samsung SSD and I could run no tests on it.

Therefore I have come to the conclusion its dead.

If I return it under warranty what happens to the data on the drive, will it get destroyed or would it be recoverable?
