I'll explain the full story.
I had a drive i backed up with MP3's about 4 years ago.
It's a Maxtor 40 GB.
It is FULL of them with only about 15 MB free.

I used an old hard drive of my Dad on a new PC we got through the post.
Installed windows, and copied all of the 40 GB Maxtor MP3's onto the big new hard drive which is also maxtor.

Recently i listened to a few of the songs on it to find that 3 of them downloaded from exactly the same site (all 3 were from the same site) infact i think i got them from FTP.
I noticed that they were scrambled (I heard other mp3s in the song that i had ages ago on that drive and they were playing throughout the song a few tracks and it kept going back to the original song.
I don't know whether it would have done this on the original drive i downloaded them to or the new one.
What i do know though is that the drive they were backed up on in the first place had no errors using ontrack recovery it had no partition errors, done a full diagnostic test and it logged no errors.
I then tested C: (the new drive i copied them to from the 40GB Maxtor.
Full Diagnostic Test - Fine
Partition Test - Fine Until half way!!
Then it errored and said critical something.

I then ran the file recovery without ticking the 'deleted files' and without realising i was just getting back files that were already on there but some were coming back in clumps like about 4 mp3s joined together, what does that mean?

It had also changed the QUALITY, some used to be 192 but were now 128 but it doesnt matter cos they were already on the pc.
I was just wondering why it got them back in Clumps and why it changed the kpbs or something?
Would it have changed the uality of the mp3s as in the uality i listen to and made it all MUFFLED or is this impossible cos its digital?

ANYWAY about these 3 mp3s business, i emailed the bloke who had them on his FTP and he said hes were ok.
So i can assume somethings messed them up.

How?
Why?
How can i get them back to normal?

It's crazy!!

I have also noticed that on other drives i have created partitions on with partition Magic using ontrack recovery that on the first second of starting off the partition test it fails.
But all the diagnostic tests run fine!!

I thought it might be useful you also KNOWING these drives are NTFS. I think 2 out of 3 were converted from FAT32 to NTFS.

Cheers guys.ne1 know?ne1 know??if you don't have a copy that isn't scrambled there isn't anything you can do but re-download them. Sorry mate

are they all scrambled or just ones from a spacific site?thass alright mate, only 3 seem to be so far, i was wondering if theres any mp3 scanning software out there to load all the files and so it can tell what ones are scrambled??Sounds like the old drive got corrupted, and if I'm not missing something, you transferred them all over to the new drive. If you still have the older drive with the original files then you can set it as a SLAVE on the new computer and listen to them directly from there too see if it was the transfer or the drive.ooh no the annoying thing is, is that i cut them all from the drive.

I was thinking, surely there must be a bit of software out there which tells u which files are corrupt and which ones arent.

Divfix was a good video error checking tool, surely there must be an mp3 one too..

Thanks 4 the help mate.
