Windows 10: Fast startup locks access to storage devices on shutdown?

[80251]

I read the following off the 'net (in the comments of: https://www.windowscentral.com/hibe...ats-best-your-pc#xenforo-comments-static_data). I have had problems using the Ultimate Boot CD utilities to access one of my SSD's (i.e. to secure erase it before using it again). Is the below true?

"You must perform a full shutdown (ie, Fast Startup must be disabled) if you want to be able to access the drive from the other OS (whether it be windows, linux, etc.). The same issue exists with Hibernate. Windows locks the operating drive so it can't be access. Also, some UEFI/BIOS settings may be disabled if you use Hibernate or Fast Startup due to similar issues."

I don't even have the option to disable "fast startup" in Windows 10 Home, the checkbox is greyed out and unselectable in Control Panel\All Control Panel Items\Power Options\System Settings. As a matter of fact ALL the settings in Shutdown Settings are greyed out and unselectable.

I think it has to be turned on in the motherboard bios before you can turn it on and off in windows

do you not have this option.

A couple side comments. There is no reason to perform a Secure Erase on an SSD unless you are getting rid of the drive and it may end up in the hands of a scumbag.

Also, most SSD makers provide a utility the can perform a Secure Erase on their drive. I recommend going with the maker's utilities rather than a 3rd party solution.

It's not anything related to fast boot, it's drive hibernation.
if you attempted to run a command to read/edit the file system while it wasn't booted, like ntfsfix in unix for common troubleshooting - you'll get a report that the drive is in hibernation state.
This happens as most microsoft disbtributed machines have hibernation enabled by default, and when the machine is suspended/shutdown (in some cases when the shutdown is actually a hibernation command) it will suspend the system environment information into hiberfil.sys

This can be disabled via a powercfg command call in CMD: powercfg /h off

must also disable fast start up in bios if u have such a setting

So if fast start isn't disabled in both the BIOS AND Windows 10, I can't access them from another OS or perform off-line scans of any of HDD's or SSD's? Or just the OS SSD?

Never seen "fast startup" in BIOS for Windows, where does anyone see that? That guide from WC is also pretty outdated.

The fast boot or something similar is not just for Windows & has nothing to do with Windows fast startup!
