Question disks present in BIOS yet absent elsewhere
Question disks present in BIOS yet absent elsewhere
I recently enhanced my PC (HP Pavilion 590-p0063na) with a new 500W power supply (L05757-800) and an RX 6600 XT GPU. The previous power supply was only 180W.
The main problems are that I can't start Windows, and both my 1 TB HDD and 1TB SSD are no longer recognized. Specifically, when connected to a second working PC, neither is detected as a disk, and the Media Creation Tool failed to locate a functional drive during a reinstall attempt. Despite this, the UEFI BIOS can see both drives, and quick diagnostics report them as PASSED.
My PC has been in auto-repair mode for about two years, but it always offered an option to boot into Windows, which is no longer available. After installing the new PSU, it worked initially, but after a few attempts it entered a black disc repair screen. The first one took a couple of minutes and then started working properly, even tests with the discs passed (using Samsung Magician and CrystalDiskMark). However, the second repair screen was the last time I saw my Windows interface. It took an hour before the PC shut down completely. After that, the second PC could no longer detect the drives.
I’ve since tried using my old PSU without success.
I’m uncertain whether the higher wattage PSU destroys the drives (though the HDD still spins and makes noise when connected). Are the drives permanently lost with my data, or does the fact that they’re still detected by BIOS and pass diagnostics suggest there might still be a chance?
I would really appreciate any advice as I’ve been stuck with a non-functional PC for several days, unsure of what to do next.
The SSD was probably around 70% used, while the HDD was about 50%. It's definitely not near being completely full. Neither device or disk manager shows any of them. I looked through all the tabs in the device manager, but found nothing.
If the power supply provides sufficient 4-pin connectors for the drives (whether SSDs or HDDs), then use them to energize the drives themselves, not the motherboard. Clearly, SATA cables are designed to connect drives to the motherboard, but power should come directly from the PSU to the drives, avoiding reliance on the motherboard as it might not deliver adequate power.
