I managed to encode my USB device having installed TrueCrypt on my Mac. I want to use the device with other Windows/OS X computers that may not have a version of TrueCrypt installed.  How do I get my USB to have the traveler disk setup that seems to be easily achievable through Windows, but apparently only there?

I need to create a file-based TrueCrypt volume in a 32GB USB pendrive. If I wanted to access my files in offline computers, I'd need to include the TrueCrypt executable in the pendrive as well. I'd like to create a multiplatform disk with all the files required to access my encrypted file-based drive from Windows, Linux, and MAC.  TrueCrypt already has an option for this: Options > Traveler Disk Setup (see ). It copies the executable portable app in the (unencrypted) drive, and has an option for including autorun.info files to automate mounting. In linux and MAC versions of TrueCrypt this option is not available I think, but the app can be run in "portable mode". If this worked (never tried), I'd have to include 3 executables in my USB drive: the Windows portable version, the Linux portable version and the MAC portable version.  So my questions:   Will the portable versions work as intended? The Win TrueCrypt executable certainly does, but what about the MAC and Linux versions? Will I need additional configuration in the host OS, permissions or drivers? I've heard that MAC doesn't support writing to NTFS (lmao). Otherwise this is the best filesystem for the pendrive since it is supported in both Windows and Linux. I could use the old FAT32 but it has a limit of 4 GB per file. My TrueCrypt volume needs to be way larger. So to make the drive RW-able in MAC, I've thought in including the NTFS-3G files in the USB, so that I could install them in a MAC machine should the need arise. Is this a good idea? Will I need admin permissions or make extensive configuration changes? (the MAC machine will not be mine, probably a hotel's or an internet cafe one). If #2 is not a good idea, I could partition the drive and include a Linux bootable distro only to cover the MAC case, and use the NTFS partition normally under Win and Linux. But Windows wont then recognise the second partition in a removable drive. I've read this can be overcomed by removing a "removable media bit" and converting the USB drive in a fixed drive. Is this bit stored or flashed in the USB drive, or is it part of the Windows OS configuration? Will all the partitions be recognised without problems in Linux and MAC? And most importantly, can a MAC run a linux live distro? Regarding #3, I've read about a Lexar tool (BootIt) that flips the bit, will this work with a Kingston pendrive?    Thanks in advance.

Reasons for wanting create such a usb include:   PC is unbootable and you want to prepare a bootable USB using the ISO file that you have on your external hard drive. to install Windows 8.1 on Mac without Boot Camp.   What are the necessary steps to create such a Windows 8.1 bootable usb on a Mac ?

Been running El Capitan since it was officially released. Updated to 10.11.4 a few days ago. I have a WD Elements USB 3.0 drive connected to my Mac mini (directly to the rear ports, not via a hub). Ever since the update to 10.11.4 whenever my Mac goes to sleep and I wake it up again, I get a notification to say the "Disk was not ejected properly".  This has never happened with this drive before, not on Mountain Lion, Mavericks, Yosemite or El Capitan until now.  I have another external caddy also with a full size 3.5" drive in it. This is powered by the mains.  It seems to me that the Mac is now terminating power to the USB 3.0 port prematurely (before the disk has had a chance to unmount properly ?), I do not get the message for my full-size disk that is permanently powered.  Tried adding the disk to the spotlight ignore list but to no avail.  Anyone else notices this issue?

Is there a way to perform an integrity check on a ready-to-use USB boot disk?  I just made a Lubuntu 14.04.01 boot USB, and have not been able to figure out how to run an integrity check on it.  I can't find any .iso file to run an MD5sum hash against.

I want to put 2 partitions on my USB stick: first one (so Windows can see it) with FAT32 (so also macOS can write to it) and a second one, bootable with  on it.  I started looking how to partition the stick and I discovered that Disk Utility will not let me create partitions on the USB stick (the button is disabled), let alone configure the partition as bootable in the MBR.  There is plenty of ways to do that on GNU/Linux, other also works on Windows but I didn't find anything for macOS. Is there any free (as a beer) way to do that?

Does anyone have a Terminal command-line recipe for making a new bootable USB flash drive for one of the new MacBook Air's?  Is there a way to dd copy the USB boot device that comes in the box and make the new copy bootable?  I'd like to make a new backup copy of the USB rescue device for my MBA, preferably on a much larger flash drive with room for a backup of some of my working directories.  Added:  And is it possible to make, not just a rescue drive, but a bootable USB drive that will boot a fully updated version of the OS (say 10.6.8 or later)?  If so how on a MacBook Air 11, and how big a USB stick will this require?

I have a Windows 7 machine with Truecrypt. I installed Ubuntu 12.04 with the intention of converting to an Ubuntu only machine but I can't install Truecrypt on Ubuntu.   I have been looking through the forums and have followed all advice to the letter and still Truecrypt doesn't work; I have only a non-functional icon in "dash". Should I uninstall Ubuntu and start over (ie reinstall)? I love Ubuntu and greatly appreciate your efforts on this forum.

A follow on to . Is it possible to just copy the plist file containing the signature from one Mac to another? Is there a recommended method for exporting and import signatures from one Mac to another I should follow instead?  I could "sign" a blank PDF and take a screen shot of it but but I really want the same password to go along with the image so it's 100% the same signature on the other Mac as the one I'm using on this Mac.

I want to use my flashdrive in Windows XP, which I am currently running in Virtualbox, but when I open up the settings to enable usb usage, I get an error: Failed to access the USB subsystem. VirtualBox is not currently allowed to access USB devices.  You can change this by adding your user to the 'vboxusers' group.  Please see the user manual for a more detailed explanation   Result Code:  NS_ERROR_FAILURE (0x00004005) Component:  Host Interface:  IHost {30678943-32df-4830-b413-931b25ac86a0} Callee:  IMachine {22781af3-1c96-4126-9edf-67a020e0e858}  Does anyone know how to fix this!?

I have a 32 GB USB stick. I was in Mac (VMWare) putting some stuff on. Then accidentally removed the drive. I put it back in, and wanted to format it. Using disk utility, I chose 1 partition, it automatically filled in 312 GB and I just clicked format or whatever. It didn't take long, then I could see the progress bar hanging at "Waiting for device to reconnect". Nothing happened for a while so I ejected it. Now comes the problem:  In Disk Utility (Mac): No sign of the USB drive.  In Paragon Partition Manager (Windows): No sign of the USB drive.  In Disk Manager (Windows): I can see that it's there. But it says: Disk 1 Removable (D:) No Media. When I right click it, I can only assign drive letters to it. No way to format.  In diskpart (Windows): diskpart list will show me the following: Disk 1, Status: No Media, Total Size: 0 B. When I eject the drive, the disk 1 will disappear. So I know that it's this drive. If I type clean, it will say that "There is no media in the device".  In HDD Low Level Format Tool 4.25 (Windows): Doesn't detect it at all.  In Device Manager (Windows): It is detected as USB Mass Storage Device.  In Gparted (Linux): Doesn't detect it.  In HP USB Disk Storage Format Tool 2.1.8 (Windows): It detects device as: "GENERIC USB Mass Storage 1.00 (0 MB) (D:)". When I press Start it gives me this error: "There is no media in the specified device"  In BIOS: Detected  In Spinrite (Live Boot): Doesn't detect it  Any help is appreciated.

I would like my external drives to be readable and writable from Linux, Mac OS X and Windows.   FAT32 works, but the 4 GB file size limit is a showstopper these days. Are there any alternatives?

According to , it is possible to create a portable "Traveler Disk" in the application:      Tools -> Traveler Disk Setup      You can use this facility to prepare a   special traveler disk and launch VeraCrypt from there. Note that   VeraCrypt ‘traveler disk’ is not a VeraCrypt volume but an unencrypted   volume. A ‘traveler disk’ contains VeraCrypt executable files and   optionally the ‘autorun.inf’ script (see the section AutoRun   Configuration below). After you select Tools -> Traveler Disk Setup,   the Traveler Disk Setup dialog box should appear. Some of the   parameters that can be set within the dialog deserve further   explanation:   My problem is I can't seem to find Tools → Traveler Disk Setup.    Am I missing something? I want to be able to share files on this disk with people running MS Windows.

I have a USB drive formatted with NTFS. I would like to use "compress contents to save disk space" option, although it is greyed out.    It works fine on the C: drive. Any suggestions?

What programs can be used to encrypt files that could subsequently be decrypted on any OS? For instance, it should then be possible to easily decrypt the encrypted files under Linux, Windows, OS X, etc.  So how can I encrypt files for maximum cross-platform compatibility?

What USB drive filesystem works out of the box on Windows, Linux, and OS X so that, when I give a 64GB USB drive to my dad, I don't have to tell him to first type in sudo apt-get install exfat-fuse exfat-utils ntfs-3g in the terminal, for example?
