I did manage to get my drive changed to Fat32 with free software recommended in this thread. I have over 4,000 cds, and enough albums etc to plastic coat a house.
I have just always liked carrying ever tune with me, overkill I know but I’ve spent years collecting and spend loads of time with MP3 tagging software, I think it may be a case of music ocd, I blame Paul gambacini. Thank you all for your replies.
