time machine backup is full
hello, first let me start off by saying i am tech challenged. i've been following steps online to clean up my time machine. via finder, i moved the majority of files to the trash. i have been trying to empty the trash for over an hour now. no success. i have a late 2012 iMac with 3 TB storage, and this external hard drive that is now full. how do i clear the trash, or how can i erase all content on the external drive and reformat it. unfortunately i really need step by step guidance ( old and tech challenged! forgot to mention the old part! ) i believe the external hard drive is a seagate.
currently my computer was showing 285,000 and now it says it cannot complete the deletion.
would anybody be able to assist. thank you
