HDD vanished once SSD was inserted into the M.2_3 port
HDD vanished once SSD was inserted into the M.2_3 port
My BIOS isn’t current, I’m stuck on version 0820 while the latest is 1801. Updating seems impossible in the BIOS settings—EZ Flash Utility doesn’t offer an update option. I checked the ASUS AI suite tool for an EZ update feature but it just says there’s no need to update. On Windows, the MEASTE tool won’t open, and the BIOS image file shows a mismatch error when inserting the TGZ590P file. My HDD is listed in BIOS stats but disappears entirely from Windows—no DiskPart, File Explorer, or Device Manager shows anything. This situation is getting worse. TL;DR: how do I update my BIOS when everything seems to say it’s not necessary?
Yes, ensure your BIOS recognizes the drive. Have you attempted using Diskpart in Windows? Launch Command Prompt, type "diskpart", press Enter, then enter "list disk" to view all available disks. Your drive should appear at least here. For instance, as shown in my screenshot, only Disk 0 is listed, but since my laptop has only one NVMe, that aligns. If you notice the missing disk, type "select disk X" and then "clean" to erase it and any partitioning issues. Once you've completed this, proceed to Disk Management, initialize it, format it, and assign a drive letter.
you only have a z390 board. but when bios switch from 0xxx to 1xxx, or now to 2xxx, they require conversion. by using the last 0xxx available, it would handle the change. then apply the first 1xxx version. after that, you can move on to 2xxx bios versions.
Sorry, I need more details to understand your message. Could you clarify what you're referring to?
installing 1203... if that succeeds then proceed to the next step. in advanced tools under bios you’ll locate the EZ flash utility for updating your bios directly inside the bios interface. avoid using any windows programs. save the file on a USB drive formatted with FAT32, then boot into bios. you should see an option to update bios there. insert the USB and load the file to perform the update; this method works for 18xx models as well. note: if the bios file name exceeds 7+3 characters, rename it to a shorter format such as bios570.bin or cab, matching its original name. otherwise, some bios may encounter issues with lengthy filenames.
If turning off or removing the SSD causes the HDD to appear again but the connection port works with the new SSD, it might indicate an issue. Make sure your BIOS is current and all drivers are up-to-date. If the problem persists after those steps and the HDD still isn't visible in Windows, it could mean a hardware fault. In that case, contacting ASUS support directly would be the best next step.
