Solved RC10: Samsung EVO 850 SSD Issues
-
@Dalton-Childers Hmmm… Not to send you down too many rabbit holes, but I wonder if you can take a working system that is using a EVO 840 and use clonezilla to clone it to a system with an 850. The source and destination computers should be the same. So the question does a current version of clonezilla work vs FOG. Both use the same underlying tool (partclone) to move the image around. So we need to answer the question does clonezilla work better/same as FOG when you use it to clone hard drives.
-
@george1421 Are these new Samsun EVO 850s or did they have an operating system system already on them at one time, and that operating system being Win10?
-
@george1421 One other test. Install a target OS on this system (with the EVO 850) from source media. Make sure it boots and runs acceptable. Use FOG to capture this image to the fog server. Then use FOG to deploy that same image back to that same computer. If that works deploy the captured image to a like computer. Its also not clear in my mind is it the EVO 850 at fault or your image (for some reason).
-
I’d lean more on the side of there actually being a problem with the flash rom on the EVO 850. What makes me say that? I’ve imaged many systems that contain an EVO 850 drive with no issues. I’m no longer with that work place, but I assure you EVO 850 is not the culprit itself.
-
For confirmation of “said” disk vs. firmware issue, have you tried a different EVO 850 disk?
-
@Tom-Elliott @george1421 Something I should have noted in the beginning is the Samsung EVO 850s work fine with FOG 1.2.0.
@Tom-Elliott Per your questions, yes we tried a different EVO 850. When I original came across the issue I tried multiple EVO 850 drives with the same result.
-
@Dalton-Childers then maybe try with an older kernel version? Maybe the driver changed and is causing this issue. I don’t know fully just trying to lead to a potential solution. Does this occur simply booting into fog or at a certain point in the imaging process?
-
@Tom-Elliott The error appears after the image has finished and the system reboots.
-
@Tom-Elliott sorry reading further thr issue isn’t in the cloning process just when it’s trying to boot
-
@Dalton-Childers can you go into a debug and get output of
fdisk -l
? Of course this on a disk that was just imaged to. -
@Tom-Elliott Exactly, the image deploys fine. The same image will work with the EVO 840s on FOG 1.2.0 or 1.3.0, and works with the EVO 850s if deployed from FOG 1.2.0.
-
@Tom-Elliott It doesn’t make it far enough into the boot process to do that with installed OS, but I could try it by other means not sure that would yield any usable results.
-
@george1421 Per your questions about the drives, they were both straight out of the box with no OS installed previously.
-
I hooked the drive into my Mac Pro and ran
diskutil list
, which return the above bit of information.The above image is
sudo fdisk disk
. -
@Tom-Elliott I’ve reverted back to kernel 3.18.2, because I found refers to that being the primary kernel for FOG 1.2.0. I’ll let everyone know if that resolves the issue…if not I’m going to try imaging a working computer (done with FOG 1.2.0) and drop the image on the EVO 850 using FOG 1.3.0.
-
@Dalton-Childers To Tom’s point about " go into a debug and get output of
fdisk -l
"What he was recommending is on the system you just imaged. Schedule a new image right away, BUT on the scheduled task page enable the checkbox for debug deploy. Then pxe boot the target computer. This will tell the FOS Engine to boot on the target computer, display a bunch of text and after a few presses of the enter key drop you to a command prompt on the target system. This is the command shell for the FOS Engine (the linux OS that captures and deploys images on target devices). Obviously this OS can see the 850 EVO. Then run the
fdisk -l
command and post the output here.BTW: I don’t think kernel 3.18 will work with the new initz. You will probably get a kernel panic when your try to pxe boot it. But that is only a guess, and I’m a bad guesser.
-
@Tom-Elliott @george1421 The kernel test failed.
Also, when you press F12 and select the hard drive as the boot option. It responds with the standard can’t find a bootable drive error. When you let it run thought pxe then fog then boot from hard drive you get the error I posted above.

-
@Dalton-Childers While I can’t answer anything about the command Tom posted I will give you a hint. If in the FOS command shell, you give root a password with
passwd
you can connect to the FOS linux via ssh (putty or what ever). That will allow you to do screen grabs and what not instead of having to take pictures with a mobile.Now that I look at that picture again, are you deploying linux to the EVO 850 or Windows? That looks suspiciously like a windows disk structure.
-
@george1421 The image is a windows image.
