Re: P50 does not detect 950 Pro M.2 SSD at BIOS level

2016-03-08, 21:55 PM

I have tried moving it from M.2 bay "0" to M.2 bay "1" yesterday, but it did not fix anything. Still had the same problems.

I'm going to try temporarily installing the 950 Pro in a friend's Dell 7510 to see if the Dell BIOS can recognize the drive. That should tell me if the problem is with the Lenovo BIOS or the 950 Pro drive.

Re: P50 does not detect 950 Pro M.2 SSD at BIOS level

I'm very interested in BIOS issues with the Lenovo.  When I bought my Lenovo W520, which this P50 is replacing, I never could get it to work with an Intel 520 Cherryville SSD.  It recognized a Samsung SSD fine, but it simply refused to recognize the Intel drive.  I spent *hours* troubleshooting that issue before I gave up.

I have the same problem, my boot driver is samsung 2.5 inch ssd.

Then I decided to use another M.2 drive to be data drive, it cannot be detected as well.

Let me know if have a solution, thank you so much.

It appears that my problem was with the Samsung drive, not the Lenovo BIOS. Another Dell computer didn't recognize it either, so I think the drive is dead. I sent it back to Samsung for replacement.

It's always funny when it *actually* does turn out to be defective hardware.  We, as users, always blame ourselves when things don't work properly.  Occasionally it actually *does* turn out to be defective hardware.  That was the same outcome I had with my Corsair memory; it really was incompatible with the Skylake motherboard.  I kept thinking I was doing something incorrectly, or I was mixing modules inappropriately, but it turned out they simply wouldn't work in that machine.  I did the same thing with a different brand of memory, and I was in *great* shape.

 

Best of luck when you receive the new drive from Samsung.  It will be interesting whether they force you to take a "reconditioned" drive.  They did that to me when their BIOS update bricked my brand new 850 Pro.  I'm still mad at them for that, but I keep buying their products.

Re: P50 does not detect 950 Pro M.2 SSD at BIOS level

I ended up returning the laptop and ordered a new one with pretty much the same configuration. I've had the new one a couple of weeks now and only once it froze when running under Ubuntu 14.04 but after turning it off the hard way and turning it on again everything was fine.

 

Either there was actually something wrong with the first laptop or the bios 1.19 (which came out after I sent back the laptop) solved the issue.

Re: P50 does not detect 950 Pro M.2 SSD at BIOS level

My new one, with BIOS 1.19, is running really well too.  I have 16GB of Crucial Technology memory (none of the factory Samsung memory is in the machine) and two Samsung 950 Pro drives.  (The Seagate 500GB spinner is long gone.)  I sent my first P50 back today, finally.  I did a backup from one NVMe to the other and it took less than 2 minutes.  The only issue I had with it was the Pantone Color Calibration Software had to be reinstalled, but that was a simple fix.

 

I guess we'll never know for certain about the BIOS changes.

Re: P50 does not detect 950 Pro M.2 SSD at BIOS level

2016-05-13, 20:58 PM

I have been working on this issue for a few weeks now and, was only able to do the Windows 7 Enterprise intall to a MBR partition. I would like a GPT partition. I've burned the ISO to a USB flash drive as MBR/Both and GPT using Rufus and still joy. Does anyone know what I'm doing wrong?

 

I've tried:

https://support.lenovo.com/us/en/documents/ht103541

in addition to Legacy boot, Both, UEFI Only, with CSM options.

 

This is very annoying and frustrating and, I will not recommed any Lenovo purchases in the future. In fact, after my experience with their 1st level support and Customer Service, I will GO OUT OF MY WAY TO DISSUADE ANY FUTURE LENOVO PURCHASES.

 

Thanks,
gn

Re: P50 does not detect 950 Pro M.2 SSD at BIOS level

2016-05-13, 21:30 PM

I have no answers for you yet.  But I'm about to embark on some research next week, when my newly ordered ThinkCentre M800-SFF desktop machine arrives (ordered for my cousin, but I do the after-market hardware upgrades and Windows/software customization and then ship the finished machine to him in NY).

 

The M800 is arriving with Win7 pre-installed on a 500GB HDD spinner, and I'll be installing a second Samsung 850 Pro SSD to be the new boot drive.  The HDD spinner will be retained and re-purposed for "data".  My plan is to use Macrium Reflect to "clone" the Lenovo-provided Win7 system over to the SSD and apply a few tweaks (for SSD),  rather than doing a from-scratch Win7 install.

 

I know from my P70 experience (which also came with Win7 pre-installed on a 500GB HDD spinner) that Lenovo creates GPT partitions on the P70 which has UEFI BIOS enabled and CSM=YES.  And this supports both Win7 and Win10, on GPT with UEFI. I know this because after installing two Samsung 950 Pro NVMe cards into the two M.2 slots on my P70 I used the same Macrium Reflect "clone" approach from Lenovo HDD spinner to one of them, leaving 85GB available for me to then install Win10 as a second bootable Windows.  This was all successful, and GPT is used and UEFI BIOS with CSM=YES is specified.

 

So back to the M800 story.  Given the opportunity to get some questions answered, I intend to build a bootable Win7 USB drive using my Win7 Pro x64 ISO and RUFUS, formatting the USB drive as FAT32 and configuring for UEFI/GPT.  I will then use this boot media first to see if I can install Win7 from scratch on the M800 (which I assume will again have UEFI BIOS and CSM=YES delivered, same as with my P70), targeting a blank Samsung 850 Pro 2.5" SSD I'm installing (there is no M.2 involved).  Specifically I want to confirm that I have built a proper bootable USB Win7 install media that can actually be used on a UEFI machine with CSM=YES and which creates GPT partitions.  Worst case, if this fails, I will simply move on to my planned Macrium Reflect "cloning" approach over to the SSD to get the job done and complete the machine.

 

Then, since I use Macrium Reflect to do my normal "system image" backups on the P70, I have no problem attempting the exact same experiment on the P70 (although I am already running happily in "production" with my two 950 Pro NVMe drives and the original 500GB Lenovo HDD spinner replaced with a 512GB Samsung 850 Pro 2.5" SSD).  I will complete erase the contents of the NVMe0 drive, and attempt to use the exact same bootable USB Win7 Pro boot media (UEFI/GPT) from the M800 story to attempt to install Win7 onto the now blank NVMe0 950 Pro in my P70.  This should duplicate your P50 situation, to see if a properly built Win7 USB bootable install media can "see" the 950 NVMe as a target.

 

NOTE: I had actually attempted something like this back in early January when I got my P70.  I had to locate the INF files equivalent to those installed by running the Samsung 950 Pro NVMe Controller Driver install into an operating Win7 system.  These INF files were then provided to the Win7 install via the F6 opportunity early in the installation, to feed in any required additional drivers not provided by MS on the Win7 install ISO (and these for the 950 NVMe drive were exactly that).  I can't remember if I provided them through an optical disc (possible on my P70, which has an optical drive) or through a second USB drive, but I know I provided them successfully through the F6 install-time option.  And I know I actually DID get Win7 installed onto the 950 (although I had other problems after that).

 

Anyway, four months later I now have MUCH MORE EXPERIENCE in fooling around with all of this.  The M800 is also a Skylake machine like the P70, and the 950 Pro NVMe is still not recognized and supported natively by Win7, and install-time INF driver files MUST be provided via F6 in order for the 950 NVMe to even be "seen" by the Win7 installer as a valid target drive to put Win7 system on (if trying to do that experimental from-scratch Win7 install to the blanked 950 Pro NVMe0 drive on my P70, for research reasons, to see if I can succed with UEFI BIOS and CSM=YES and getting GPT partitions).

 

Should be a fun time next week.  Two separate Win7 install from bootable USB stories likely, one for the M800 experiment (onto a blank 850 Pro  SSD) and a second for the P70 experiment (onto a blanked NVMe 950 Pro). Note that in both cases there needs to also be a way to have access to all of the Lenovo-provided drivers and software utilities that are not part of the base MS Win7 ISO installer.  So these need to be pre-downloaded and placed somewhere that is then accessible to the "bare bones" Win7 just installed.  I'm talking about USB 3.0 drivers, Intel network adapter drivers, Intel chipset driver utility, graphics card driver, etc.

 

I need to keep a detailed log of the two separate experiences, to share my discoveries and "paths to success" whatever that might have entailed.

I think Windows 7 did not ship initially with native NVMe support.  It was added in a hotfix.
