Not sure why it wouldn't show it to you. Perhaps try another drive?
Thanks Gary, I found the problem. I had partitioned my thumb drive (Mac OS, & MS Dos) and was trying to format the existing Mac partition alone... not sure why this can't be done... do you know of a way?
Perhaps you can't have an encrypted partition -- only the whole drive.
Same Problem Here Garry&Richoff.I am running on a SnowLeopard 10.6.8.All i have is this:MS OS Extended(journaled); MS OS Extended ; MS OS Extended (Case sensitive,Journaled) MS OS Extended(Case sensitive) ; MS-DOS (FAT) and MS-DOS.
Do i have to have this option on my Snow Leopard or how can activate it?
Pretty sure this isn't available in Snow Leopard. You need to have Lion.
If I encrypt by 2 GB flash drive as Mac OS extended (encrypted), will this drive's formatting still allow me to use it on me Windows 7 Bootcamp partition?
I don't think so. Not unless you also have some software installed in that Windows partition to read OS X-formatted drives. I don't think Bootcamp has anything special to read OS X drives, but I've never looked into it.
for those like me not using snow leopard, best to make an encrypted password protected dmg and save/move everything in there.
I meant LION obviously -- sorry for the typo.
Yep. See the old episode 46: http://macmost.com/protecting-files-with-a-password.html
Can this be done with a USB that already contains data, or will the data be erased?
Reformatting will erase the data. So you just copy it to your main hard drive. Reformat. Copy back.
Hi Gary, I don’t see the option for “Mac OS Extended (Journaled, Encrypted)… I’m running OS 10.7.4. I tried a second thumb drive, same problem????
Not sure why you don't see it. Hard to tell where you nay be going on without a first-hand look.
I selected the wrong item, once I reviewed your video and selected the right item it worked. Thanks again.
What if i forgot the password for my encrypted usb drive. There is no info on the drive, i just want to be able to use it. I tried to use disk utility to re-format the drive but it won't allow me to. Any help would be great. Thanks
I haven't tried it, but you should be able to erase it. Try selecting the drive on the left and not the partition on the drive. See if that lets you erase it.
I don't feel very confident in using the Mac to encrypt my drive. For many years I was a windows fan until I switch to Mac. The Mac works great but the recent concerns on the internet about that Apple considers their system to be extremely secure but in fact it is working with out-to-date security measures made me purchase a third party software called "Encrypt Stick" from a company in Canada call ENC Securities. I've been using Encrypt Stick for a few month now and are very satisfied. Just a few days ago I realized that this product also works on my Windows machine which makes it even a lot better because a big draw back of everything that I do on my Mac (i.e. make documents with pages): it is't compatible with any other OS.
Gary after setting a pass word can the Password be changed? How to?
Thanks for your fine work.
Good question. Not sure. Try it -- Control+Click on it after it is already encrypted. But my feeling is no, since it is encrypting the data using the password as a key. So you would need to un-encrypt it and then encrypt it again to get all the data encrypted with a new key.
