I plugged in an external drive, (maxtor if it matters) it doesn't show up in finder although it has previously. I followed the other threads on this subject, but couldn't find an answer. If I look in Disk Utility, I can see the drive, although pressing the Verify Disk button renders the following message: Verifying volume WORK Invalid Volume Header Checking HFS Plus volume. Checking Extents Overflow file. Checking Catalog file. Invalid node structure The volume WORK needs to be repaired. Error: The underlying task reported failure on exit 1 HFS volume checked Volume needs repair. The Repair Disk button gives similar results. One thread I followed said to open Terminal and type the following: id ls -l /Volumes ls -l /Volumes/WORK echo --------------- The response to this was "no such file or directory" Any ideas???
