Trouble with nbperfchk

This issue has been solved. See solution.


I have a issue with nbperfchk. My write test was successfull. I used the command nbperfchk -i zero: -o T:\test -s 80g -syncend.

Now I want to do the read test and use the command: nbperfchk -i T:\test -bs 1M -o NUL.

All i get in the console are the following lines:

9 MB @ 0.0 MB/sec, 0 MB @ 0.0 MB/sec, at 1382082483.

The last number counts up every line by 3, the rest stays the same. for over 2 hours now. 

Am I doing something wrong or is there a hardware/software issue?

Thanks for your help

I believe your command prompt is "run as administrator", isn't it?

What if you just try with C:\somefile.txt   (assume somefile.txt exists in C:\) ? 

Might want to check with Symantec support...

Hi Bublebeeman85,

Sorry, I'm editing my earlier comment. But essentially you can try experimenting with different buffer size value, e.g. 4096k.
