Solved Very high physical memory usage on Windows PC

Very high physical memory usage on Windows-7 PC - when using Western Digital usb external hard-drive: WDBAAU0020HBK

When viewing an mkv movie (4GB) stored on my Western Digital External USB hard-drive on my windows-7 pc my physical memory starts at 22% and creeps up at about 1% per second to 98% physical memory usage.

Even if I terminate VLC.exe after opening the mkv movie within 10 seconds of playing it the physical memory usage still increases to about 98% and will return to normal levels only about 4-5 minutes later.

To Isolate the problem I copied the same mkv movie from my WD usb ext hard drive to my pc internal c-drive, and played the movie with vlc.exe player from my c-drive with NO memory problems at all. So this is clearly a WD ext hard drive (driver/usb related) problem. I cannot find any help or any new drivers on WD-support site.

Any suggestions to fix this problem other than purchasing a new external hard-drive.

Great News - The PROBLEM is RESOLVED....

1. I un-installed the Divx crap
2. I re-created my mkv file (from mkv video only + DTS Eng Audio Track)
But as I did so I monitored the mkvmerge process with my window-7 Resource Monitor, and guess what....
After mmg.exe finished (click ok) the physical writing of the new mkv output file had not finished !!!!
So I WAITED for another 2 mins for all writes (buffer writing out as monitored by Windows Resource Monitor) to the output file to COMPLETELY FINISH BEFORE I accessed the new mkv file.
3. IT WORKS! - no more problems or memory leak.

there is something on the external hard disk causing this memory usage, perform a full scan on the external hard drive make sure its clean of any malware or viruses.
Try the external hard disk with the same movie on another computer and check if the memory problem exists

Sysinternals has a lot of good diag tools if you can't get the internal performance monitor to find the issue.

hi toxist51 - thx for the tip - could be right about malware/virus. now the hi-mem prob is happening also with the same mkv file on my c-drive - so it's the file, the disks are ok. I played other mkv files with vlc.exe on both disks - No probs.

I tried to rename the mkv file - but explorer stoppped responding, memory use went up, and I had to restart explorer after hanging several minutes -- the file will not rename!

I tested the original mkv file (which does not contain audio-tracks) - it's ok. But when I merged dts-audio track to the mkv file -- the new mkv+dts file has the problem! I used this mkvmerge GUI v5.8.0 software (9801 kb)downloaded from mkvtoolnix to do the merge.

I did scan both the software and files with norton internet security - all ok!

I did however manage to merge the ac3 audio with the mkv file using nero-vision and the resulting mp4 file was playable but a little jumpy (skipped frames).

So, I guess I will need to delete the merged mkv+dts file I created.

Updated Sept 9, 12: -
---------------------------------
I deleted the problem 4GB mkv file - it took about 4 minutes to delete - windows reported deleting / calculating, and the memory use went to 98% in about 2 mins (delete part-1) and dropped then to normal, and then went up to 98% again in about 2 mins (delete-part-2) and then went down to normal after delete mkv file completed successfully.

It seems that this mkv file was not created properly by mkvmerge GUI v5.8.0, and was probably missing the end-of-file (eof) indicator mark.

Consider also that your memory was acting as a buffer for the movie when played from an external source to prevent jumping but as an internal file on the hard drive, Windows did not see the need to buffer it.

You have to be a little bit crazy to keep you from going insane.
