[SOLVED] Windows 10 Pro not showing other drives after installation (URGENT)

[bhabanisankardas007]

Hi,

HP Z820 Workstation BIOS shows all the 4 drives working properly.

While a fresh installation of latest Windows 10 Pro( Build version 1909 ), I did not find any other drives.

Is there any other thing I missed windows 10 pro installation ?

Any help would be appreciated.

Thanks.

Go into Disk Manager and see if the drives show up there. Also, do you see your platform pending any BIOS updates?

No, Disk Manager not showing any drives.

Latest BIOS for HP z820 installed.

So 3 of the 4 (internal?) drives are not showing in Windows 10. Is this a new install or an upgrade? What is the make/model and size of the drives. When you installed Windows 10 did you disconnect the 3 other drives? How are the 3 other drives partitioned/ formatted? Do they contain any data?

Yes, all are internal, All are not showing in Windows 10.

All 3 disk are from Western Digital (1 TB each).

No, I did not disconnect all the drives while installing Windows 10.

All 3 disks are having 55 to 65% data before fresh installation.

Yes, All important files are on them.

What type of drive is the OS drive? Did your PC have Windows 10 working previously prior to the fresh install? Are the drives hdd or sdd. Was your fresh install similar to the clean install described in this link? https://forums.tomshardware.com/faq/how-to-do-a-clean-installation-of-windows-10.3170366/ Is the BIOS set at the default?

Did your PC have Windows 10 working previously prior to the install?

Yes, It was working perfect with Windows 10. I did not change anything at all.

I just went for fresh Windows 10 installation.

What is the make/model of the forth (OS) drive? Confirm you are using a SCSI Raid array? If so check this link. https://www.tomshardware.com/news/how-to-set-up-raid-windows-10,36783.html

Yes, HP z820 has internal soft raid which is already configured & it is working properly.

I already followed this tutorial too.

I'm left with recommending you unplug the other drives and reinstall Windows. Hopefully another member will be able to pick this up and offer more possible solutions.
