My external HD - Buffalo Ministation 320GB HS-PS320U2 just gave up on me. The drive doesn't show up on the desktop but it does show up in Disk Utility as: 298.1 GP SAMSUNG HM320JI MEDIA Derek Backup (this is greyed out) When I run First Aid in Disk Utility, it says: Verifying volume Derek Backup Checking HFS Plus volume. Checking Extents Overflow file. Checking Catalog file. Invalid node structure The volume Derek Backup needs to be repaired. Error: The underlying task reported failure on exit 1 HFS volume checked Volume needs repair Tried Disk Rescue II Trial Version - it does indicate that there are files and folders, but it won't revive files over 5MB, which most of the files on the HD are. Also, considering getting Disk Warrior, but only as a very last resort. Glad if any of you could help.
