Hi, 

So i have task sequence that runs ok. It does everything, i even implemented bitlocker logic to encrypt the disk. If however i try to rebuild machine that is already enctypted my TS fails on start with error 0x80070070.

To fix this i pres F8 and then do manual DISKPART. Then after reboot the Task Sequence runs ok. I tried to implement the DISKPART in the TS in the very begining.

I have created package containing .txt with 2 instructions:

"sel disk 0 

clean"

Then i execute diskpart /s textfile.txt as 1st step of my TS.

Unfortunately this doesn't seem to work for me. Any suggestions?

create a batch file to copy it somewhere in c:\temp and then include your command to run from there.

If you're deploying Windows 8.1 then you can use PowerShell to remove the dependency on a separate file. For an example see: http://www.cloudoscommunity.com/blogs/How-to-automatically-clean-your-disk-at-the-start-of-your-task-sequence

Try to add the step "Disable Bitlocker" at the beginning of your task sequence.
(next step is "restart in windows PE"). Start the task sequence from Windows.

I think the error code is inherent to Bitlocker.

Hello,

0x80070070  ERROR_DISK_FULL  There is not enough space on the disk.

I think the installation process allocate a small partition which is not large enough for a system. If in that case, there could be some problem with your diskpart settings or apply image settings.

Ivan, you don't have a disk to write to, so you need to "build" a command file with the diskpart steps in it by echo'ing them to a file on the RAM drive. Then call diskpart with the setup file created and "clean" the old disk so you can then partition and get started.
