Rekorbox Export Problems To New External Hardrive

Hi.

I have a couple of problems which I need help with.

1. I have recently moved my data base from one EHD which was on my F: drive to a new and bigger EHD. I followed the instructions about migrating the Pioneer files and what I did was once I had moved all my tracks to the new EHD I applied the new EHD to F:drive which is what is linked to my Rekordbox and then changed the old drive to G:drive as a backup.

Now for some reason on certain files I downloaded to Rekordbox as wav files ripped from CD's these are not being found on my Rekordbox, but it doesnt come up on display all missing files it will only show file not found when you double click on the track or have exported it to your device.

1. Since I have done the above when I try and add new wav files to my Rekordbox they do get imported and will play but when i change the info say from Electronic to Drum & Bass or add the album name the file becomes currupt, it will then not play and if I delete it from Rekordbox and try and re up load Rekorbox will not do it, I have to delete all the files and re rip the cd to wav and then re import !!!

I am proper stuck and am pulling my hair out !

I am using windows XP Pro, have the latest version of Rekordbox, 2.2.3. and all my files on my Rekordbox are pointed to my EHD on my F: drive, what have I done wrong ? I also have my Rekordbox program files on my F: drive, should I have left it on my PC harddrive ?
