    HDD in BIOS but not in Windows (not unallocated)

    by snadge1 ·



    I had an issue which required me to switch out motherboards with an old replacement with a second-hand board from 2012, the Intel DQ77CP for £50 – a bit expensive I thought but ALL i could get that had what I needed to get back up and running.

    now, I got it all set up with just the SSD, reinstalled windows, drivers installed – fully updated – Norton on, restarted, everything fine…now i start adding my other disks, it picks up my 2TB WD but won’t pick up my other 500GB of which is 2.5″ – they show in the BIOS but do not show in DISK MANAGEMENT or any other tool like Mini-tool Partition wizard

    another strange (but unrelated and not important) thing i noticed is that the windows drive (C:\) only has 1 reserve partition of 579MB and every single time ive installed it for people its always had 3-4 partitions..hidden obviously

    now – the BIOS is NOT in UEFI mode – is this why? and..should I change it? I am in AHCI mode on the BIOS, the SSD is running on ‘Standard AHCI Driver’ even after running the intel INF program, before it would be some form of Intel driver?

    can anyone help or tell me why these drives are not been shown to windows by the BIOS?

      There could be various reasons for the HDD to become unresponsive or undetected. The drive may get detected by the system if you connect it to another PC, but it doesn’t respond.

      You can try the below options to resolve the issue:

      1. Run CHKDSK
      2. Use an Antivirus & Anti-Malware tool
      3. Re-install the drivers

      Apart from that, if your hard drive is giving any of the below indications or warning signs then there are chances that your drive might be failing:

      1. The drive is undetectable or unrecognized.
      2. The system fails to boot.
      3. The drive begins to make strange noises.
      4. The system gets heated soon.
      5. BIOS is unable to detect the drive.
      6. Files or folders become invisible or corrupt.
      7. Slowing down of the system.

      Well, one has to keep backup of their data so that if there is any data loss situation or anything bad happens to their storage device at least they had a backup of the files, but when your drive got corrupted and you also don’t have any backup of your critical data in that case performing data recovery operation is the only option.
