How do I encrypt a flash drive

Hello,
Im trying to encrypt my flash drive, but when I try it says A GUID Partitioning Table (GPT) partitioning scheme is required, but I also want it to work for Mac and Windows if I can, how do I do it?

If you need an encryption you can share between mac and windows, I'd advise you to use something like truecrypt.
You create a crypted container (the name you want) that you can mount as a drive. The app itself can be stored on the key as a portable app for windows.

How to creating a secure flash drive

I would like to encrypt a flash drive; or preferably a folder within the flash drive. Please advise about the proceedure.
Thank you.

Setting up an encrypted disk image is a no brainer. I don't know how much these hardened flash drives cost. It may be they are no more expensive than the usual suspects, but I would imagine they cost more and being restricted to these will limit choice.

How to Create a Bootable Flash Drive to do a clean install of Lion. I have tried to use the InstallESD.dmg but it still will not do a clean install so that I do not have to do a reinstall from the Recovery (That just re downloads and takes over 6 hours)?

How to Create a Bootable Flash Drive to do a clean install of Lion. I have tried to use the InstallESD.dmg but it still will not do a clean install so that I do not have to do a reinstall from the Recovery (That just re downloads and takes over 6 hours)?
The system I'm have is a Mac-mini that had SL on it and no SuperDrive. I have also call Apple Support and they have really have not been to much help over 1st did my up grade to Lion and Installed the Lion Server.... it lost my SSL that I paid for and kill almost on of my server setting, plus kill all my web servers (using apache vhosts), and not to say the LDAP will even let remote users login to your laptops.
PS: There is no way that I'm going to buy a Install USB from Apple... They have over billed me over $300.00 because the Apps Store still has bugs (Glad I did not write that App/Service)
If there is anyone that can give in the information to create a USB install stick, I would be very thinkful.

Here you are bro, courtesy of "softpedia.com"....brilliant site!!!
If you ever had problems with your Mac OS X installation you know that the first thing you should do is to check the startup volume using Disk Utility.
After the check has ended and, if the errors exceed a certain level of seriousness, the Disk Utility application will require you to restart your Mac and use its Mac OS X Install disc counterpart.
Other users may have to reinstall OS X altogether, but will find, or already know, that their SuperDrive (a CD/DVD reader and write combo drive) is not functioning properly and it will not be able to read the Install disc.
Although this might happen to Mac OS X Leopard users due to faultyhardware, the vast majority of problematic SuperDrives will be encountered inside Snow Leopard running Macs.
This is due to the updated SuperDrive firmware included in either the Install disc or the software updates one has to install to reach the latest version of OS X, namely 10.6.6.
This can be fixed by flashing the SuperDrive’s stock firmware using free command line tools that one can find for free online (I will write about this process also, but at a later time because this article only focuses on allowing you to create your own alternative USB boot disc).
If you are reading this last bit of information with skepticism, than you should know that it happened to me too. Despite all my tries to make it work properly, the SuperDrive kept on munching any inserted DVDs and just popped them out in about twenty seconds.
The workaround to this issue was to create my own Leopard bootable USB memory stick. I am not suggesting a Snow Leopard bootable stick mainly because there are lots of users that have decided to buy the cheaper, Upgrade version, which I have not tested and, therefore, I’m not sure if it will work properly once written to a USB disk.
And now, here are the exact steps you should follow in order to obtain a fully bootable Leopard (or Lion) Install disc.
Step 1 (If you already have the Leopard install disc DMG file you can skip to Step 2)
Launch Disk Utility (you can find it inside /Applications/Utilities). Here select the Leopard Install disc in the list of drives on the left and click on the New Image menu entry at the top of the window. A save message will appear where you will have to select the Desktop as a destination.
Step 2
After Disk Utility has finished creating the Leopard DMG, insert your USB stick and erase all data and reformat the disk. To do this select the USB in the list of drives on the left and, after clicking on the Erase tab on the right side of the window, choose the Mac OS Extended (Journaled) format and click the Erase button beneath.
Step 3
After the USB has been reformatted, download the SuperDuper app from HERE and launch it. Once SuperDuper starts, you will only have to select the DMG in the Copy drop-down menu, your USB memory stick on the right and hit the “Copy Now” button.
One can also use Disk Utility for this task but creating a bootable USB stick failed 2 out 4 times when copying the DMG to the stick (with the exact same settings each time). Creating the bootable stick using SuperDuper proved to be the perfect way to do it because it worked each of the 4 times I tested it.
The steps above can also be used to create a bootable Mac OS X Lion USB by using the InstallESD.dmg image you can find inside the Lion installer (named “Install Mac OS X Lion.app”) downloaded from the Mac App Store in the /Applications folder.
To locate the InstallESD.dmg right click the Lion installer, select the “Show Package Contents” entry, go inside the “Contents” folder, and from there into the “SharedSupport” folder. Inside this folder you can find the InstallESD.dmg you can use to create your own bootable Mac OS X Lion USB stick. To do so, go to the third step described above and use the InstallESD.dmg as the DMG to be copied to your USB disc.
That’s it! Once the process ends you will have a fully bootable Leopard (or Lion) USB disk that you can use as an alternative to the Apple’s DVD Install disc that comes bundled with all Macs.
To use your newly created bootable disk you will have to restart the Mac, press and hold the OPTION key until the StartupManager appears. Here, select the Mac OS X Install disk using your keyboard arrows and press return to start from the selected drive.

How do I see the flash drive?

I have a flash drive plugged into the computer. I see its icon in the Sidebar. But it would be more convenient if I could see its icon on the Desktop. How do I get the flash drive to appear on the Desktop?

Finder -> Preferences -> General. Checkmark to show external disks. That should do it.

How to boot from USB flash drive - Portege R500

Hi,
I have a Portege R500 running Windows XP, brought about 2 years ago, and recently contracted a worm virus that has infected some of the start up files as the minute I log in it logs out again, even in safe mode! Quickest way I can think of sorting it is to reformat it with the XP recovery disc and reinstall windows.
Problem!! The CD/DVD drive on the laptop stopped working a while ago, have tried pretty much everything in the thread on this site but had no luck.
So my plan was to boot from a USB flash drive and do it that way. However in the boot settings I only have the options of HDD / FDD / CD-ROM / LAN, neither of these will work. Does anyone know how to boot from USB flash drives?
Any help would be really appreciated

Hi
As far as I know it should be possible to boot from USB FDD
Im not sure if you would be able to boot from USB flash drive but its definitely worth a try
Generally you could try to press F12 button when notebook powers up.
Then a boot menu should appear on the display and you should see all bootable devices.
PS: As far as I know the USB booting was available in ToshibaHWSetup (Toshiba tool which changes the BIOS settings in windows OS.) Therefore I assume booting from USB should be possible.

How to install (using usb flash drive) os x snow leopard on 10.5?

i have a version 10.5 (leopard), but i would like to install snow leopard (10.6). i tried using bootable usb flash drive using the "utility drive". However, it did not quite work as i expected. Does anyone know how to use bootable usb flash drive to install snow leopard on leopard?

How to Install OS X Updates Successfully
A. Repair the Hard Drive and Permissions:
Boot from your current Leopard installer DVD. After the installer loads select your language and click on the Continue button. Then select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
B. Make a Bootable Backup Using Restore Option of Disk Utility:
Open Disk Utility from the Utilities folder.
Select the destination volume from the left side list.
Click on the Restore tab in the DU main window.
Check the box labeled Erase destination.
Select the destination volume from the left side list and drag it to the Destination entry field.
Select the source volume from the left side list and drag it to the Source entry field.
Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.
C. Important: Please read before installing:
If you have a FireWire hard drive connected, disconnect it before installing the update unless you will boot from this drive and install the update on it. Reconnect it and turn it back on after installation is complete and you've restarted.
You may experience unexpected results if you have installed third-party system software modifications, or if you have modified the operating system through other means. (This does not apply to normal application software installation.)
The installation process should not be interrupted. If a power outage or other interruption occurs during installation, use the standalone installer (see below) from Apple Downloads to update. While the installation is in progress do not use the computer.
D. To upgrade:
Insert the USB flash drive.
Restart the computer.
Immediately after the chime press and hold down the "OPTION" key.
Release the key when the boot manager screen appears.
Select the icon of the USB flash drive and click on the arrow button below the icon.
When the installer finishes loading follow the onscreen instructions.

How to make a bootable flash drive Disk Utility's "Owners Enabled" function

Being as Apple does not have a discussion group for this wonderful little utility and because Apple has neglected to fix the "Post New Topic" link in the "Special Interest Area>User Tips Library", I have no choice but to post here. I think what I found is useful and I have accomplished it in a way that avoids the need of using the disheartening Terminal.

How Do You Test a Flash Drive for Errors Using OS X?

HI. In Windows there are Flash Drive tester that tests if there's something wrong with the Flash drive's chips. How do you test a flash drive for errors on OS X? I bought the HP v220w which is tiny for a 16GB and it's metal. The whole thing goes into the plug. Design wise, it is great, it's very elegant like a jewelry. Thanks in advance.
Gbu.

Format it for OS X and run a surface scan on the partition. That should show any hardware problems that don't keep it from working altogether.

Encrypted USB Flash Drive with Lion OS X questions

Like many of us, we don't want our USB flash drives lost with our valuable data on them. So I've used the encryption function in Lion OS X in Disk Utility to make an encrypted flash drive. This has some limitations as I read but what I want to know is can I use this usb drive on a DIFFERENT computer that also has OS X Lion? I don't have another mac w/ lion to test it on.
This is important to me because I've got a laptop and God forbid, but if it was stolen or destroyed, will I be able to access my USB drive with important data on it by plugging it into another mac computer w/ lion?
Also, as a follow up question - I haven't yet made an encrypted DMG file (tho I plan to soon) and place that on a usb drive for multiple platform use, but how functional is this? Can you add and copy files within the DMG file? I thought a dmg file, once created, couldn't change in size, MB's, etc.
Basically, I'd like to use the most user friendly type of way of securing my files and data on USB flash drives. I have tried TrueCrypt and have it installed but I just don't prefer using it. I like the simplicity of the former approach, though it has it's limitations.

How about any computer instead?
Hardware based encryption is superior to software encryption which can be hacked or not available if your needs change.
This will work with any computer, and has a nice keychain so you can attach to something like your wrist or retractable key cable.
http://www.amazon.com/IronKey-Secure-Hardware-Encrypted-Flash-D20402A/dp/B000RXY V5U
There are also hardware based encypted external hard drives with their own keys and password keypads, also work with any computer if your needs are larger then a USB can handle.

Disk Utility / Encryption on Flash Drive used on Windows & Mac

I am interested in using a flash drive whose contents are encrypted. I will be using this flash drive to open/trasnfer files between a Windows computer as well as a Mac. Does anyone have any solutions for running an encryptiont that can be used on both platforms.
I have come across the opensource GNU Project. Is this the best technology use? Also there are different apps for each platform that use this standard. If this is the best solution, do you have any suggestions which are the best apps to use on the Mac and on the PC side?
Thanks,
Tim

"In most cases we recommend you select Microsoft’s exFAT format: this will give you full read and write access in both Windows (Vista or later) and OS X (Snow Leopard 10.6.5 or later)."
That's what I've done so that the flash drive can be read in Win 7 and OS 10.6.8 and above.

How to remove document from Flash drive after printing from a PC

Hi All,
Here's my problem: Today I needed to print an MS Word file at a printshop, so I saved the document onto my Flash drive and took it to the shop. There, the staff printed the document from a PC and handed the drive back to me.
Now, back at home, I want to delete this document from the Flash Drive. I plug in the drive, select the document and drag it to the trash. But then I get this message: " The operation cannot be completed because you do not have sufficient privileges for document X".
This is a document I created from scratch, so I should have read/write privileges, yet the document on the drive is Read Only.
I went back to the shop, and they get the same message.
If I try to use disk utility to erase the disk, it appears as an MS-DOS FIle System (FAT 16) disk, and the erase buttons are "greyed out".
How can I erase this document? Or how I can I reformat the drive?
Any help much appreciated!~

I think I just solved my own problem. Just tried pressing the option and command keys at the same time while dragging the document into the trash and now it's gone. For good, I hope....Phew!

How do I eject the flash drive from an Officejet 8610 after scanning a file into it.

I used the front panel controls of my Officejet 8610 to scan an image into a flash drive plugged into the front panel of the 8610.
The 8610 recognized the presence of the drive just fine, and placed the scanned image on it as desired.
But for the life of me, I cannot figure out how to do a controlled ejection of the flash drive. (I finally did a controlled power-down of the 8610 and removed the drive after the 8610 turned itself off.)

How to reformat a USB flash drive?

I have 1.33 GB available on my Buffalo USB 2.0 GB Flash Drive that is formatted as MS-DOS File System (FAT 16).
Suddenly, every time I try to copy a MS Word document from my iMac to the flash drive I get the following message.
+"The item cannot be copied because there is not enough free space."+
I reported this to the Buffalo customer service and they responded with,
+"When you look at the files in the USB flash drive, do you see a lot of temporary files? Please delete these. If there is no other solution, I would like you to copy your good files onto your computer hard drive, reformat the USB drive, and copy the good files back onto the USB drive. "+
I did not see any temporary files, so I'm thinking that I have to reformat the flash drive.
But how do I do this?
I've backed up the files on the flash drive to my iMac.
I insert the flash drive and click on Disk Utility.
I select the flash drive icon and...
What do I do now?
The choices at the top are First Aid, Erase, RAID, Restore.
BTW, I am running on a iMac 2GHZ Intel Core 2 Duo, 2 GB 667 MHz DDR2 SDRAM, OS 10.4.10.
As is evident, I have no idea about computers.
Please advise on a step-by-step basis.
I thank you in advance for your assistance.
