i1000 · 30 Jun 2019

Set up:

Laptop: Lenovo Ideapad 520 Type 81BF
Processor: Intel i7 8550u
RAM: 16 GB
Graphics: NVIDIA GeForce MX150
Hard Drive: 128 GB SSD + 1 TB HDD
Software: Windows 10.

OS is on SSD.

Laptop running fine for over 1 year and suddenly when computer restarted HDD missing from File Explorer.

HDD was not showing in Disk Management but it did used to come in Device Manager (hidden)

Tried out all of these below repeatedly in different sequences:
1. Windows update
2. Driver updates from Lenovo, Intel and 3rd party apps
3. Uninstall from Device Manager (hidden in Disk Drives, Portable Devices, Storage Devices etc)
4. Registry repair using Tweaking.com app
5. Windows start up repair option
6. Command prompt - Check disk, scannow
7. Safe Mode
8. Uninstalled unnecessary apps, disabled 3rd party antivirus
9. Run Malwarebytes
10. Different BIOS Settings, changing sata controller

2 times during Restart the disk was detected and working fine but disappeared during restart. While the disk was detected complete Disk Test was done using Lenovo utility, Windows Disk Check, Defragment, Command prompt check disk, scannow was also done all were fine.

Last thing done was restart with Boot Log:
The following drivers did not LOAD according to it

BOOTLOG_NOT_LOADED \SystemRoot\system32\drivers\wd\WdFilter.sys
BOOTLOG_NOT_LOADED \SystemRoot\System32\DRIVERS\NDProxy.sys
BOOTLOG_NOT_LOADED \SystemRoot\System32\drivers\dxgkrnl.sys

All of these were mentioned multiple times in the Log. The start up time (boot time) is fine. No issues with it.

The Driver List from System Information has been attached.

Please let me know if any additional details are required.

Have you tried checking the connections and cables?
Try unplugging it and re plugging it. It may be just a loose connection.

No I actually did not try that as it is laptop and never been opened before and not fallen or damaged so I assumed that connections are fine..

No I didnt do that actually because the laptop has never been opened or damaged in any way so I assumed the connections were fine

Just a thought, The drive showing and then not showing usually a hdd going bad or loose connections.
Since all the tests cane off well, checking the connections was the next thing to check.
check to see that the drive caddy or bar that holds the drive down are tight.

There is a board that mounts on the dvd caddy blank for the second drive. Pull the problem drive and use an external enclosure to see if it can be seen. If it can, then you can narrow it down to a bad interface board on the caddy or bios issue.

. In the Bios on the System Information page, it should list your drives. If the drive is not seen in the Bios, it will not be seen in Windows. If so, then there is a connection issue (ie) cables, or connector, or the drive has failed. Removing the drive and attaching it to another computer via a USB Adapter, Dock or Enclosure with a power adapter on another computer would tell you that.
