Copied MP3s are corrupt

I'm having a problem with MP3 files becoming corrupted when I copy them to an external device. The MP3s reside on my 15" MBP retina's internal flash drive. When I copy them to a microSD card in the MBP's SD card slot using an SD to microSD card adapter the files become corrupt. I've tried different SD cards, different adapters, and I've even tried copying directly to an external device (MP3 player) using a USB cable. No matter what I do the files are corrupt.

Another clue could be that the first 10 or so files copy fine, and the rest are corrupt.

I'd like to try copying in safe mode, but in safe mode the MBP's SD card slot is unavailable.

Does anyone have any ideas what could be going on, and how to resolve this issue?

Thanks!

Can you describe how you know these files are corrupt?

Do you get an error message when you try to play them? If so, what is it?

Or do they play, but with hiccups and stutters?

Or do they have a different icon? Or what?

Can you copy these files to other media devices -- DVD, external hard drive, USB flash drive -- without problem?

Thanks for the reply.

I know the copied (destination) files are corrupt because they won't play on the device (phone). Also if I check the files with MP3 Scan and Repair it says the format is unknown.

After the copy process, the copied files won't play on any device.

It seems like a clue must be that the first few files copy fine and the rest are not.

One more thing, after copying the MP3s ejecting the disk hangs as well. I have to restart the machine or force eject which I don't like to do.

Were the MP3s created in iTunes? Or something else?

Has this process ever worked in the past, or is this something you've never tried before?

And the MP3s play correctly on your Mac? And they are definitely MP3s, not m4a or aac...?

Does it matter which files are the first 10? Or not? (i.e. if you copy 10 files at a time, does that work?)

How many files are you copying in one go?

takoateli, I have had this same problem.. Unfortunately the only solution I have had success with is with re-downloading the individual MP3.

As the curruption seems to have only effected a select few tracks, I mark down the corrupted songs in the notepad on my phone as I come across them and re download them at a later time.

Its a small project but unless anyone else has had success using another method this seems to be it

Guys, I'm sorry for being AWL on this. I'm in Venezuela with limited internet access and limited time. I will get back with more answers soon.

Let me answer what I can now.

Q. Were the MP3s created in iTunes? Or something else?

A. Something else. I picked up these files from varous sources. I acquired them as MP3s

Q. Has this process ever worked in the past, or is this something you've never tried before?

A. It worked in the past. I'm not sure what changed.

Q. And the MP3s play correctly on your Mac? And they are definitely MP3s, not m4a or aac...?

A. They play fine on my Mac, and they are MP3s.

Q. Does it matter which files are the first 10? Or not? (i.e. if you copy 10 files at a time, does that work?) How many files are you copying in one go?

A. I'll need to research that and get back to you. I'll try to do that soon.
