| | Testing
For testing the software I tried uploading and downloading songs to
the player on both Windows ME and Windows 2000. It worked great on
Windows ME, but I did experience a problem on Windows 2000. After
installing the software the Unplug or Eject Hardware icon would be
displayed in the systray. If I attempted to stop the device by right
clicking on Unplug or Eject Hardware and then selecting Stop D-Link
DMP-120 NTJCMP3.sys MP3 USB device, I would receive the blue screen
stop error with the infamous Driver_IRQL_NOT_LESS_OR_EQUAL error.
The error pointed the finger at the uhcd.sys as being the culprit
of the problem. If I just removed the device without ejecting it via
the software it worked without a problem. I did however have the player
actually lock up twice if I just unplugged it without ejecting via
the Eject Hardware icon.
I researched some bulletin boards and found that there is an updated
uhcd.sys available in a hotfix from Microsoft for Windows 2000,
which fixes another related problem with a USB keyboard. This problem
may fix the MP3 error also. Unfortunately, I did not have access
to the hotfix to test it out.
The Digital Voice Recording portion of the player worked without
a problem. I was able to record my voice and play it back with good
quality.
Conclusion
While there are still some issues with Windows 2000, I had no
problems with Windows ME, the player worked without a problem. The
software is very simple and easy to use. The only problem one might
have starting off is distinguishing the appropriate button to upload/download/delete
files, as the buttons are not labeled with text, just icons. As
the majority of users will probably be users with Windows 98 or
ME, I would see no problem in recommending this product. If you
are a Windows 2000 user, I would consider maybe researching this
product some more and see if any others are experiencing some issues.
Bottom line, if you are in need of a simple MP3 Player to upload
files to and listen to on the go, this is a player you should look
at. The Digital Voice Recording feature is great for people on the
go that need to remember something, but either don't have access
or time to some paper to write it down on. Plus, its also easier
to carry this player than to keep track of things you were going
to do on a piece of paper.
