[QUOTE="PGB1, post: 1826662, member: 76746"] Hello All! I have been trying to make an encrypted sparseimage to store the contents of a small PC hard drive that I will erase. (Disk Utility - File - New Image - Blank Image) I asked Disk Utility to make it 8 GB in size. The resulting file turns out to be 52.6 Mb in size. I tried many times and received the same results. I did notice that after changing from the default of 100 MB, Disk Utility will change it back to 100 MB after the password dialog is completed. Going back to change it back to 8 GB still results in a 52.6 MB file. (That's not a typo- It is [U]mega[/U]bytes) My computer's hard drive has 54.04 GB free space left. To be certain I was not misunderstanding, I tried copying files to the new image. The report was that it was too small. Next I tried making a sparsebundle. I got the same results, except the file came in at 26.3 MB. Copying files to it gave the same failing results. [I]Interesting: The sparsebundle file size arrived at exactly half that of the sparseimage.[/I] Coincidence or Clue? I have made both encrypted sparseimage and encrypted sparsebundles many times on this computer with success in choosing the size I needed. Do you know what went haywire on today's attempts? (OS X 10.11.6) Thanks! Paul [/QUOTE]
