How did you format the external drive? It needs to be FAT32 if you want it to be able to be read and written by both PC and Mac. Sometimes when LR says "cannot be read" it also or instead means "cannot be written".

it was in nfts format, i just changed it over to the newer version of fats32 and will let you know how that works as soon as I am able to work with it again. Thank you for the suggestion....
it worked like a charm,, thank you so much for the assistance. I appreciate it!!!!
I just tried to import some new photos using the same external drives that I was successful with before, now they are giving me the same "cannot be written" message but all of the hard drives are formatted to fats...any other suggestions on what I can try next?
