I tried transfering some files from my macbook pro to an external drive using the drop and drag/command last night. I also dragged a few things to the trash. I thought everything had went well, until I got the message my startup disk was almost full. I think I forgot to empty the trash before ejecting the external drive. From what I can tell My macbook harddrive is still accounting for all of the hard drive space used from the files I transfered, as well as the ones I deleted. I transfered like 18 to 19 gigs, and mayby deleted a gig if that. any idea on how I can get my hard drive to recognize its not full?
