Maybe I'll just get the Lenovo and call it a day, if that doesn't work I return that and get the Schenker...

Yeah I know that feeling, never easy to decide. There is no perfect Notebook... I bought the ASUS G501 at a good discount price at first. The first model had a broken GPU, the second one had a defective display bezel. The entire thing had so much flex, I could break it easily by accident. I thought thin was good, but I really wanted something more durable.

Anyway, have fun with your new machine Wink

Weird as shit issue that I thought I would ask you guys about.

So I work in IT and I recently upgraded a companies entire staff to SSDs. They were all using the exact same model system with the exact same bios version and settings. Some of the computers have an issue where they will randomly not detect the SSD at POST. And by randomly I mean you can restart the computer 10 times and maybe 6 out of the those 10 times you'll get a "HDD not detected" message and the other 4 it will boot normally. And sometimes it may even freeze/power off during operation. Again this seems to be totally random and not linked to uptime or system load. Event viewer shows nothing helpful.

I have tried:
-different sata cables which are confirmed working
-different sata ports
-different SSDs
-different SSD models

It's as if these systems somehow have a compatibility issue with all SSDs. Putting a HDD in them exhibits no problems. Yet they are all the same model, bios version, and bios configuration and only about 25% of them have the issue. I cannot figure it out. It seems like a hardware issue with the mobo but then why does it only effect SSDs? Recently I've started seeing tickets from other companies with the same issue on completely different computers with completely different SSDs.

im guessing timing/protocol issue with the mobo effected by the environment (humidity, temperature etc etc).
since replacing the SSD seems to not fix it im guessing its either the SSD model doing it or the mobo's SATA/SSD implementation.

i dont know what you have to your disposal but have you tried a different mobo model ?

Is there a BIOS update for them?

@DacoTaco
It's not the SSD model. The systems that have the problem experience it with any model SSD. A different mobo model would probably work but that's basically equivalent to getting them a new PC. That's not a very easy or cost effective fix for them.

I want to know what is causing it, why only some of them are experiencing it, and what can be done about it as I am beginning to see other model computers experience this issue.

@KHg8m3r

They're all on the latest bios. I've tried rolling back but the problem systems seem to do it with any bios version.

i know its like buying a new system (depending on current hardware) , but it would be a good way to test Tongue

what you can also do is replace the psu with a psu that can give alot more power then the pc needs. maybe its reaching the peak and that is fluctuating. ive seen that happen as well. also worth a shot Smile

like i said, i think its either a timing issue caused by difference in the environment or the power supply.
the only things that can cause an issue actually xD

**KHg8m3r** · 08-01-2015, 07:10 AM **#947**

An SSD draws less power than a HDD, so its probably not pushing the PSU to hard. If the PSUs are bad and can't provide a steady stream of power due to being old that could be an issue.

ye thats true...
changing psu would probably not fix anything ye, but worth a shot.

1) I'm sure you've made sure to check in the BIOS that drive detection is set to automatic?
2) Are the SSDs all using the same controller inside them? Research the brands to see what controller is inside them, and make sure you have the latest firmware installed on them.

**NaturalViolence** · 08-02-2015, 01:55 AM **#950**

1) Yes
2) As explained previously the problem machines encounter this issue with any SSD. I have tried multiple brands with different controllers. And yes I have tried updated the SSD firmware too.
