SOLVED !!! Internal SSD Drive (not OS) disappearing when copying files.

EDIT - SOLVED !!! (new PSU/power cable solved issue)

-----------------------------------------------------

A bit stumped on this.

Bought some new gear recently and having issues in testing.

Copying large numbers of video files from se card to an Internal SSD (not C Drive)
I intend to use this as a working SSD on video projects

The copy process works up to around 30% (say 100gb) then grinds to a halt. The volume disappears in Windows and I get an error “specified volume does not exist”

I’ve tried alternative data cables, motherboard, changing drive name, disk checking through windows)
(Actually the disk didn’t format properly when I tried that am when the volume disappeared during that too)
Windows is saying the driver is up to date and no better ones are available.

To a normal HDD I’ve had no issues at all.

Don’t understand this. Can anyone suggest a way to fix?

What SSD is it? Have you run the manufacturer diagnostics?

Any information in event viewer around the time it disappears?

Honestly, it sounds like it is broken. I suppose it could be overheating, but they usually just throttle rather than disappear. Have you tried a different power cable on the PSU?

Assuming you are copying to the Samsung SSDs in your list, have you used Samsung Magician to check for any available updates for each of the drives?

Also, is your motherboard on the latest BIOS? The latest version, 7B93v1G1(Beta version), was released a little over a fortnight ago.

Could also try some live Linux to see of problem persists.
But definitely sounds like drive might be broken.

I've had this in the past and changing the SATA cable fixed it. I had it several times with the 3rd party AKASA short/thin ones and the problem went away when I put the motherboard supplied ones back in (just in case you had tried swapping similar cables).

Also had a similar problem with my HTPC, HDD kept disapearing in windows.

Changed the sata cable with the locking clip to a normal friction fit and the problem is solved.

I tried a different data cable and no joy.
Also, as above I did look for some software on samsung's website but I couldn't find any downloads for diagnostics, only a copying tool which only works if you have an OS on it, this one doesn't) I think they just take them back and look for repairs. (Or perhaps I'm a noob and couldnt find it)
I had tried installing up to date drivers (didn't flash bios, but didn't see any BIOS updates that looked like they had better SATA controls or anything.
I had ordered a new PSU and with that (and new cables) it worked without an issue. Same SSD used.


My thought would be it was either the Power cable or the PSU itself, either way. All good now.
After weeks of issues in my last build, I'm finally set up with a working Rig
Thanks for your suggestions and help.
