## Symptoms

- * User tried to copy files to a USB drive and the encryption stops at 0% and does not progress.
* In some cases, the process will progress to 33% and hangs for a long time again and/or takes an hour to complete.
* DNCLi.log shows `MEUIControl ---> DisplayBarDialog Drive:D:// progress:100 description:Failed Creating encrypted storage on media...`
* The USB drive appears to be running out of space during these events, even when sufficient storage is available.

## Cause

The issue is related to formatting the drive before encryption:  
Here is a sample log:  
1/7/2025 15:46:19 TID=0x49b8 Wipe device D:  
1/7/2025 15:46:19 TID=0x49b8 MEUIInterface.cpp --- IDisplayBarDialog  
1/7/2025 15:46:19 TID=0x49b8 MEUIControl ---\> DisplayBarDialog Drive:D:// progress:0 description:Wiping media...  
1/7/2025 15:46:19 TID=0x49b8 MEUIComm ---\> CallTray  
1/7/2025 15:46:19 TID=0x49b8 MEUIComm \<--- CallTray returned 1  
1/7/2025 15:46:19 TID=0x49b8 MEUIControl \<--- DisplayBarDialog returned Result_Ok  
1/7/2025 15:46:19 TID=0x49b8 BackupPlainDataAction - without backup on HDD  
1/7/2025 15:46:19 TID=0x49b8 \[MediaEncryptionEngine::FsFormatEngine::Format\] start ...   
1/7/2025 15:46:20 TID=0x49b8 FsFormatEngine::Format failed for drive D, last format error = 16   

In this example, Symantec DLP was installed on the machine, preventing format operations and filling up the drive during file copying, which caused the process to hang.
