Windows 10: Bitlocker encryption stuck and it seems to slow down entire system IO

I have multiple disks on my Windows 10 PC.

I did BitLocker encryption on g: yesterday and it stuck at 94.8%.


After rebooting I can unlock the drive, encryption resumed at 94.8%, but any access to folder or file is very slow.


When I watch task manager, there is no meaningful IO transfer under 500KB/s from g:, but it use 100% of activity time or usage?.

Even in resource monitor, there is absolutely no file access to g:.


Weird thing is - systems is running very slow if it is disk related launching a new program, accessing to any other drive

I guess BitLocker blocks some kind of system IO and slow down entire system IO.


Any of below commands are not respond. It seems to stuck at launching these command


chkdsk d:

manage-bde -pause d:

manage-bde -off d:


It happens again and again after cold reboot. Can't reboot normally because system stuck during shutdown progress

BitLocker encrypting Used or Entire space?


I usually been reinstalling Win10 to get rid of the so called "clutter" on my system to make it more fresh and such.
Regarding BitLocker, I always select to encrypt the entire drive as opposed to encrypting used spaced only.
The entire drive option takes literally 9 hours to encrypt and complete.
So I was thinking, is it wise to always select Encrypt Used Space Only whenever I reinstall in the future or is that option only for new machines and drives?

I just don't have the time to wait for my entire drive to be encrypted as I need to work on my programs and during the encryption process it just slows my system down.

When encrypting the used space only, new and existing data will be encrypted?
Am I correct?

So when I reinstall Windows 10 the next time around, should I select encrypt Used Space Only?

Just want to save time.

Any thoughts or suggestions?

Thanks

 

BitLocker Encryption Process? Used or Entire Disk Space?


Hello everyone,

Since choosing to encrypt the ENTIRE drive with BitLocker which can take very long time to complete, can I encrypt the Used Disk Space only when re-installing Windows 10?
When there is a need for me to reinstall Windows, here is how I do it.

1. Boot from USB to boot the Windows or Windows 10 OS setup process
2. Then, I wipe every drive/partition under the Advanced Page section were you can format or delete all the drives listed. I usually take all the drives listed and DELETE them until I see the only one listed as Unallocated Space. That's it. Everything else is deleted.

Then I continue on with the Windows installation.

Now, this is NOT a new drive. This has been used a lot to reinstall Windows. But I always DELETE ALL the listed drives that I see until the Unallocated Disk is listed only.

So, my question is this. Will I still need to encrypt the entire drive or will encrypting the Used Space Only will be OK since I deleted all the drives and started from scratch when reinstalling Windows 10?
Or does encrypting the Used Space Only applies when getting a new physical disk or PC?

Because the issue I want to avoid the next time I reinstall Windows (in case I get bit from malware or something like that), is to wait 10 hours to encrypt the whole drive again...

Now its too late, because I already began the entire disk encryption with BitLocker.

But I do want to avoid waiting in case I do have to reinstall Windows 10 again.
