Explorer.exe hangup during move large file into external drive
- by PiotrK
During move large files (700mb+) to external drive formated NTFS via USB 3.0 I've noticed strange things about explorer.exe (I am using Windows 7 up to date)
Sometimes after move file the explorer get stuck (ie. it can happen after few files during move of several large files) - moving window freeze and I am unable to kill explorer (via taskmgr, or cmdline TASKKILL). In command line I've got something like this (taskmgr shows that explorer.exe is still running - I've got the same PID every time I try to kill it and no diagnostic message):
C:\Windows\system32TASKKILL /F /IM explorer.exe
SUKCES: proces "explorer.exe" o identyfikatorze PID 6296 zostal zakonczony.
C:\Windows\system32TASKKILL /F /IM explorer.exe
SUKCES: proces "explorer.exe" o identyfikatorze PID 6296 zostal zakonczony.
If I try to run another explorer.exe process at this point, I got desktop icon and start bar back but I cannot open any explorer window
After few minutes explorer.exe finally dies and I am able to rerun it without rebooting
File that I moved have two copies - one local and one on the external drive (the original file wasn't delete after move); Both copies seems to contain the same data (same length and CRC info)
If this happen during move of multiply files, only some files are moved and one of them have two copies (both locally and on the external drive)
What can I do to fix those explorer hangs?
Added:
The same problem exist when copying files, it hangsup between large files
Similar problem exist when I tried to use TotalCommander (x64): copying paused at 80% of one of files, TC didn't hung up (but clicking cancel in copying dialog box doesn't have any effect). During this pause I can't kill TotalCmd.exe just like Explorer.exe
Added (2):
This problem seems to disappear when I use 32 bit applications (like TotalCommander (x86) ), but I need to do more testing to be sure of this
Added (3):
There are several errors in event log, source: disk, id: 11, qualifiers: 49156, task: 0, level: 2, keywords: 0x80000000000000
(This may be important, and I forgot to mention this): Main disk is encrypted via Truecrypt (boot-in password)
