I bought a WD SN770 and installed it and strange things happened. At first the computer seemed to boot up properly but after a few seconds it froze and I needed to power down using the on/off button.
Next I went into the BIOS to see if I needed to somehow activate the second SSD drive but it only showed that there was one drive installed.
Then when I went to start the computer after that it wouldn't get past the circle of dots for Windows. So I again powered it down and removed the new SSD and it booted fine. Then I re-inserted the new SSD and looked at the original and noticed a discrepancy. The original SSD (also 1 TB, different brand) shows 3.3V, 2.5A while the new one I was trying to get to work shows 3.3V, 1.8A.
One of the strange reboots with the new SSD installed gave me a "no bootable disk found" message which scared the heck out of me. But removing the new SSD solved that issue.
I know I'm supposed to use a gen4 x4 SSD, and that's what I thought I was ordering with the WD SN770.
I'm sending the WD SN770 back and have ordered a PNY XLR8 CS3040 which specifically says gen 4 x4, but I can't find the volts or amp rating for it.
I never was able to get to Windows Disk Management to partition the new SSD because the BIOS didn't recognize it.
Any suggestions about what I might have done wrong? I'm typing this on the computer in question, so I obviously know enough to take it apart properly and put it back together to keep it working fine. I thought these were just "insert, boot up, partition, format and start using."
Is there some other step I don't know about?
Thanks in advance for any insights!
