Are these file types the real file types?

By dariquew ·
There are mp3 files that a client is paying me to upload and organize on their XP machine. There are several folders full of mp3 files that are not recognized as audio or (or even video). WMP screams wrong file type, VLC won't even give an error message, and windows media classic brings the following as its error message:

C:\Documents and Settings\Delta Bravo\My Documents\The Eminem Show\01_Curtains_Up.MP3:utput

Media Type 0:

Notice that the file is listed as filename.mp3. I assumed that the file may have really been an mpeg1 file just renamed to assume an mp3 role (if that even makes sense). I attempted to use a batch editor and the batch editor wouldnt acknowledge files as audio of any type (the reason i assumed video) I am completely at a loss and I rely on you, my technical brethren to shine some light for me.

By 'upload' I am assuming you mean to COPY onto their XP machine - to upload would be to send onto a site within the internet.

Thus, if you are indeed COPYING these files onto a computer running XP - where did the files come from? Where were the files prior to them arriving on this XP machine?

The files are on a 150gb WD External Hdd. According to the client, before then, the files all played normally.

Before when? Before you started to do whatever it is you're being unclear about doing?

"A bicycle made for two" ...

by OldER Mycroft In reply to bad phrasing

A slow bicycle at that - I'm also not quite getting this.

This 150gb WD External Hdd - does it appear normal within Disk Management? How does it seem inside Device Manager? How much of it is populated?

If there are files OTHER than the supposed MP3 files, do they appear normal - can they be read without difficulty?

BUT - I'm with Ron K on this. "According to the client, before then, the files all played normally." Is this client aware the files don't 'play' properly and has this client tasked you with recovering them (as opposed to just transferring them)?

This situation appears to be a little light on detail.

files transferred onto a hdd. client hires me to configure new pc and upload files. i upload files and forget to install sound drivers. i go and install sound driver. check mp3 file to test. mp3 file not playing. re check the driver installation. no problems there. i check meedia player (media player classic, windows media player, and vlc) they are properly installed. i check mp3 from different location. no go. check another random location. mp3 works fine. spend ( a very long) time checking mp3 and video files. only certain folders of music are not playing. i ask client if these files were ever played. client assured me most of currently broken files were recently used and working properly. tried some random (somewhat thoughtless) solutions, including attempting file conversion, tag editing and codec pack. above error is from media player classic (most detailed error message). external hard drive functioning properly. not sure if i left anything pertinent out.

Delving into the murkiness ...

by OldER Mycroft In reply to details

I'll deal with the salient points in the order you presented them above...

#1 Firstly, I would ask that you refrain from using the term UPLOAD because it just confuses what's left of my logical brain. I keep thinking of an online connection to a website. What you are actually doing is TRANSFERRING, by either Copying or Moving these MP3 files.

#2 You mentioned forgetting to install the sound drivers - by the time you realised this, had you already connected to the M$ site and updated the install? If the sound driver is from 'Realtek' you CANNOT install it successfully once you have contacted the M$ site and updated the system - Realtek drivers are not authenticated and will not be accepted by an updated Windows installation.

#3 Associated with #2 above: you said "i go and install sound driver. check mp3 file to test. mp3 file not playing." - by "not playing" can I assume that means there was no error message but you just didn't HEAR any sound? (That would relate to having installed sound drivers after an online system update)

#4 "i check meedia player (media player classic, windows media player, and vlc) they are properly installed." - How exactly could you tell they were 'properly installed'?

#5 "i check mp3 from different location. no go. check another random location. mp3 works fine." I have to say that different location and random location doesn't really tell us much - different to WHAT? You have yet to illustrate WHERE these files have been copied to in terms of directory tree. What is the way you have 'organised' these files?

#6 "..only certain folders of music are not playing.. ..client assured me most of currently broken files were recently used and working properly."

So now we're getting somewhere - the client clearly was aware of file corruption prior to handing you this can of worms. If, as you say "only certain folders of music are not playing" it is NOT UNREASONABLE for me to suggest that you are banging your head against the wall, looking for (and asking us for) a solution when your current problem files are very probably exactly the SAME as the ones the client already knows DO NOT WORK!

What on earth is a client doing giving you known corrupted files? That is a nonsensical arrangement that can only result in frustration, searching for a non-existent answer.

**I would add this - ascertaining why MP3 files are not playing properly is NOT part of your remit. You were contracted to setup a new system and organise a directory tree of suitably arranged music files.

If you have been given corrupted files, that is not your problem. You can only work with what you are given.
:)


Edit for **

Yep.

As far as the info you have given indicates.

What computer was the external drive originally attached to? Was it the same machine which you are trying to play the files on now?

Some possibilities:

1) Look at the file size. Is it unrealistically small? It could be a link only, not a true media file.

2) The machine you are playing them on now does not have the proper codecs.

3) They are infected.

4) They are corrupt.

4) Direct Show and both media players are broken. (Not very likely, is that?)

5) They are protected by a DRM scheme which is broken, so you get no warning, but the files are unplayable.

Anyway, if you are a bit more clear as has been previously suggested, you might get better answers.

hmmm.....

by dariquew In reply to Yep.

my current thoughts are either corruption or broken DRM scheme (idk what a drm scheme is but other options are not true)
