I have 4 machines i am working on all four have same problems Hard drives are not being detected ( even after a Motherboard replacement ) The Bios will not detect any drives but when in Device configuration you can the see the drives . 3 machines have Intel® VROC Standard raid controller ( all 3 machines are using NVME M.2 SSD in all four bays )
The other Machine has 3 SATA Hard drives using hdd 2.5" drives ( i tested each drive and they work properly )
I know that the problem could be anywhere raid controller card , flex bay daughter board , cables, SSD M.2 etc. Has anyone seen this before ? seems to be happing to often
I am wondering if it is in the setup in device configuration ?
I assume you manually loaded the needed Intel RSTe (rapid storage enterprise) driver while the windows installer is booted, before reaching the installation location selection ?
Also to my knowledge the 5820 and 7820 can have only 2 flexbays converted to u.2/nvme . Do you have an optional raid controller installed to handle all 4 flexbays (and so both backplanes have been changed) ?
Is the 4th machine having non converted/standard backplanes for the flexbays ?
Hello Thanks for answering, to answer your question "NO" i would assume the driver was already there ( the machine is 2 years old was working fine until last week )
And yes the machine does have 4 conversion drive bays and has 4 1 TB NVME ssd m.2 ( 2 are connected to the raid controller the other two plug into the mother board )
THE 4TH machine is using standard backplanes using SATA 3 connections ( NO CONVERSIONS ) i recently updated the Bios Firmware
Well, with a pre existing install that was working, the driver was already loaded in it obviously. But maybe it got updated on auto with a wrong version (just an idea).
The 4th machine is more troublesome since it should just work, unless again something got drastically altered by an update.
Would I be right in assuming that all 4 stopped working ( as in started having this issue ) at the same time ? Was the bios updated just in one ?
Hi so to answer your 1st question it did not get updated . ( there are 3 machine with almost the same configuration that are not detecting the 1 tb ssd drives all 4 of them
2. the 4th machine did not have any updates within the past 2 weeks
3. the 4th machine that has 3 SATA 3 DRIVES ( sas ) the mobo was just replaced and the drives will not show up in the bios , al the cables were check along with the backplane , the system has a raid 1 configuration along with a raid controller card . The drives do show up in the device configuration . but when the system is turned on it will post but can not find the O.S.
No the machines did not stop with the problem at the same time
For the 4th machine ( mb replaced ) , chances that the raid controller somehow lost the raid configuration data in between being removed and reinstalled ?
(if you have a backup of the data, you could recreate the array and reinstall the os)
