I'm using an old eMac with Tiger, and have connected a WD Passport external hard drive, a very small one. I reformatted the drive with the help of WD's support line, but seem to have a problem transferring my iPhoto library to the Passport; it stops transferring info when it runs into a given photo, saying that the particular photo is in use. I'm not a technical person, and there's no Tiger update for the Passport drive, and the only things the drive needs to protect is My Documents and iPhoto. Can someone tell me how to go about this simply? I could really use some advice here. Thanks for reading. Sincerely, Sparrowhawk.
