Solved

SSD doesn't show up after each system boot.

Hello,

my SSD randomly stops working after I shut it down especially at night time when I am off to bed. I did try with different sata cable, different power cable and it won't turn on the next time I boot my pc. it doesn't show up in the BIOS.

here is the weird part, after couple restarts it randomly reappears out of no where! is my SSD dying or there is something else that I am not aware of which I am doing wrong?

system:

SSD health is at 95% too so that is fine.

thanks guys any help would be appreciated.

  1. Why is your SSD showing as a SCSI?

    Probably not the right SATA port.

    sorry, what does SCSI mean? I am not familiar with this lol

    it's still connected to the same SATA port as when I got it. plus my HDD works fine every time.

  3. yes, you should immediately tell us which PSU you have... what you explain is likely problems between SSD and PSU...

    look SSD is bit more sensitive at the point of stable voltage supply compared to HDD. And i have seen your problem quite often in industry - which resulted in many dead SSDs, caused by unstable power supply.

    Another option when thinking again, is the power up sequence of PSU / SSD - if they do not match, they would have problems. Look, SSD gets 3.3 and 5V from the sata power cable. Some SSD use 3.3V other 5, and other both - if the timing when and with which speed the powers come up, does not match the expectetion of your SSDs power circuit - it will refuse to start up.
    If the power sequence of the SSD and the board are close to each other to match sometimes and sometimes not - we would see your failure description.

    hey, thanks for the reply.

    my PSU is evga 600W

    and here is where your problems start... you combined a "priceworthy PSU with "almost" stable voltage and an SSD with older controller generation SF2281 (roughly 10 years old).

    Further i would assume your SSD is not brand new - get yourself some backup and watch it dying - if above 3 years old - if not try to find FW upgrade, that might help a bit - nevertheless, get yourself some backup!
    and last but not least, try to test another PSU, may be you can borrow one - to test if it helps...

    I have been using my SSD for about a year and a half. definitely not above 3 years.

    my SSD is connected to one of the 6 ports, does SCSI have anything to do with, maybe?

  7. 1. Forget about the "SCSI" designation re the SSD. The Microsoft OS (Device Manager) frequently refers to a SATA HDD or SSD as a "SCSI device". It's not unusual at all.

    2. I would doubt the PSU is the root of the problem. If you had a PSU tester that would probably tell you, but I have my doubts it's the PSU. I assume you don't have another PSU that you could substitute for the present one.

    3. And you've indicated (although you haven't PRECISELY stated) that you've tested the SSD with a diagnostic program and it checks out OK. Right?

    4. I assume your 1 TB secondary HDD does NOT contain an OS. But perhaps it does. If so, could you try booting to the OS on that drive?

    5. Or if you did have another HDD or SSD handy could you install the OS onto that drive and trying booting to it? (Or clone the contents of the present SSD to the drive and see if it boots to the OS?).

    6. Have you tried running the sfc /scannow command to check on the integrity of the OS files? If not, do so. If you're not familiar with that command, do a Google search on using it.

    hey, thanks for replying.

    as of now my ssd was able to boot after so many tries, I do have OS installed in my HDD which I was using earlier. the SSD would completely disappear from the BIOS and computer.

    the OS seems to be fine. it's just that my pc won't pick up any signal from the SSD what so ever. it really is strange.
