Razr V3ti mp3 player

Hi all
I've got a Razr V3ti and I need an info about the mp3 player. I've got a 1gb card in it with about 150 songs. All are fine I've redone a few that showed a number at the beginning instead of the song and artist name. Here's my problem when I click on digital audio and I go into the mp3 player I then click on songs to play them all by the way they're all alphabetically listed which is fine, I click on song and the first one I've got is #8 I found out which one it is and I've redone it (took the card of the phone read it on my pc and when I click on it it's fine)with an mp3 converter "all music converter" which is what I used to do all the other one it works great. when I cut it and paste it on the card named "my music J usb on my pc" it tells me that it's corrupted. I tried to delete it, it deletes it but it leaves the name there with 0 byte. When I put the 1 gb card back in the phone the #8 is still there I simply cannot redo it. If it's corrupted I will simply remove that #8 all togeter. How can I remove the song once and for all if corrupt or redo it?
If this part of the card is corrupt I will simply remove the song and of story.
How can I do that? I've tried with the pc to remove it and it's not working
Thanks
