Dead Crucial SSD ?

I have a 512GB Crucial MX100 SSD which I've been using for some time in a Zalman ZE-400 enclosure (wonderful ideally totally flawed in execution with the dead keyboard).

Anyway, I took it out to re-use to install W10 on my new desktop. The PC would see it, but when I tried to format, it wouldn't take it because it was in MBR instead of GPT. OK, so I bring up the console to change to GPT and it won't do it, saying the media is write-protected even though it is not.

In the end I use another SSD I had so got my W10 up and running. But now, if I have this SSD plugged in, my machine won't POST - I presume it hangs trying to detect the drive.

I then change the SATA port to be a hot-pluggable one so I can boot without it connected into Parted Magic / GParted to see what's going on. I plug the problematic drive in and then get a load of errors. It is detected as a 500GB drive, but I can't seem to do anything with it. See screenshot.

If I hot-plug it once booted into W10, it does not see it at all in Disk Management.

Drive is now out of warranty. So it it totally dead?

Have you checked to see if it works in another system? Occasionally you'll get seemingly random conflicts between hardware, sometimes helped with firmware updates.

Have you check UEFI / BIOS to see what drive has priority if you're trying to boot with multiple drives? I have multiple HDD and every now and then the preferred list gets jumbled. It won't boot (cos it's trying to boot from a drive which isn't an OS drive)

Could be a cable fault.

Failing that, what does the "Crucial Storage Executive" program have to say about the drive? You might be able to perform a drive reset from there, return it to factory fresh if the firmware has freaked out. There seems to be a recent firmware update too so that would be worth applying.

I don't suppose you have one of the sata to usb cables that were sometimes bundled with ssd's as an upgrade kit? Maybe windows will detect it then?
