Question SSD randomly disappears ?

[srknfzt]

SSD Model: ADATA SU750 2.5-inch

There is no specific event that causes this SSD to disappear. After a shutdown and reboot post a few hours, the BIOS doesn't detect the SSD and I have to do 2-3 shutdown and restart iterations to get it back.

Right now I have a couple of solutions:
1st - Restart while in BIOS screena few times
2nd - I'm unplug the cable then plug it back in while in BIOS , and it gets fixed.

I'm looking for a permanent solution.

-Ive checked wires OK
Pins : OK
BIOS : Updated to latest version
Motherboard : Asus a320

Back up your files ASAP and consider replacing the SSD.

I've already formatted . I'll buy a new one if I'm sure the problem is caused by the SSD

Best way to troubleshoot would be to have another known good SSD, and assuming SATA, another cable to hand.

I've just replaced with another SSD which is working for sure , but did not work. After 2-3 shut down it detected same as previous ssd. What else can it be the issue ?
Why does everything go normal afte 2-3 shutdowns whilst in BIOS ?

Seagate :
Ive replaced Sata cable . Right now there is no issue . And I went to the technician we tried 3-4 times with old cable and it did not happen. And we replaced new cable its still good But later I changed again to the old cable and ssd disappeared .Now its working with new cable. I m still not sure what is the reason. I m gonna test it and let you guys know about results.
