I want to protect my USB flash drive in general so these files and directories are readable but not copyable so no one can make a copy of these files in my USB flash drive.  Is that possible?

I have customers who want to buy large amount of flash memories but he wants to copyright all files inside it.   The flash will contain files that will be delivered for his customers but they're not allowed to copy or delete any of the files the only allowed permission is to ready the files.   I searched and found many solutions but all have on function it WriteProtect the USB though I can't add files to Drive at all but I can delete or copy any file in the drive.   Is there any way to protect the flash memory so I can't copy data out of it?

How to make some file that contains crucial data protected? For instance, suppose I have some files that are important, is there any method or strategy to make these kind of file more protected on Ubuntu? I even want to make some files ask for a password whenever someone tries to open it. Does it affect the version of Ubuntu in terms of security policy? May I use any encryption algorithm externally? Regards.

I want to encrypt a USB stick, and be able to decrypt it on Windows as well as Ubuntu. How do I do this &amp; what programs do I need to use?

When inserting a USB stick or device to computer, there is always the risk that the device is malicious, will act as an HID and potentially do some damage on the computer. How can I prevent this problem? Is disabling HID on specific USB port sufficient? How do I do that?

I am trying to encrypt an entire USB drive with Truecrypt 7.1a. But as long as there is a partition it will only encrypt that. This will make it appear like the USB is full instead of completely empty, which isnt what Im aiming for.   I've tried with DISKPART, USB Partition Tool, and the built-in storage manager. When I delete all partitions, Windows still assigns the drive a letter and assumes that it has a partition covering the whole space.  I know that it is possible as I have done it with another USB, but I just don't remember how I did it.  Ideas?

Whenever I try and copy a file to an USB flash disk, the progress bar runs till the end very fast and stops for an indeterminable time before it is complete.  Is there an issue with ubuntu or my flash disk is what I am not able to figure out. All I want is a realistic copy dialogue

Say I have a directory with these permissions:  drwxrwx---   Inside this directory, a file with these permissions:  -rw-rw-rw-   Is the file readable/writable by everyone or not ?  If not, how secure is this access restriction?  What if a random user makes a link to my file inside his home directory? Could he access the file then?  Or could he access the file by guessing its inode number and using some system calls on inodes?

What permissions should a udev rule have for a USB device? 644? 755?  For example on Ubuntu I'm looking at this file: /etc/udev/rules.d/99-lpcscrypt.rules

Out of the box, Windows will not allow you to partition a USB Thumb / Flash Drive. How can you do this?  In case anyone is wondering Why you would do this?  It's interesting in the case of a  drive where you can take a large thumbdrive (like 4 or 8 GB) and format a small amount of the drive to be used normally as a Fat32 drive and leave the remaining partition encrypted using BitLocker. This allows you to keep some non secret data on the unencrypted partition(like portable apps).

How can I find all files I can not write to?  Would be good if it takes standard permissions and acls into account.  Is there an "easy" way or do I have to parse the permissions myself?

How to edit label of USB drive easily without formatting it? I tried right clicking the device and go to the properties but cannot find anything to edit.

Sometimes I unplug my USB drive only to find out files were not written to it.  I suppose the only way to ensure files are written to it is to right click on the USB drive on the desktop and then select "un-mount", but sometimes I forget.  What is the best way to ensure files are written to the USB drive instantly? This way I can remove the USB drive as soon as I notice the LED light on the USB drive stopped blinking.  OS: CentOS 6

Environment: Windows 7, but applies to other EFS-compatible Windows versions  I have a file that is encrypted using standard Windows EFS encryption. When I copy that file to a USB drive using Total Commander or Explorer, the file stays encrypted at the destination.   Such encrypted file is inaccessible on any other Windows PC where my USB drive gets plugged in. I could import my personal certificates on that PC, but that's about the last thing I would like to do.  I would like the copying process automatically decrypt my file when the file is copied to a removable drive. Is there a way to tell Windows to do that?  A brute-force way to decrypt the file on-the-fly would be to switch to FAT as a file system on my USB drive, but I don't want to do that either.  Thanks in advance for any hints!

Sometimes when I follow the process to safely remove a USB flash drive, I get told that I can't remove the drive because some programs are using it. However I'm unable to tell which programs these are, so I end up having to close programs - sometimes even randomly.   How do I find out which program is using my USB flash drive?  I've searched the Internet but have found nothing promising; one solution might be via Process Explorer since it shows handles, but I don't know how to use it to solve my problem.  The best solution would be to have a program that can automatically close these programs for me, or at least tell me which programs these are.

Some kinda voodoo, indeed.  Bought a new boot drive, and it's time to use the old drive for data. I thought I'd save some time by just wiping the unneeded system folders, instead of backing up, formatting, and restoring. Wups!  I have a single Adobe file that absolutely will not be deleted. G:\Windows\SysWOW64\Macromed\Flash\flash9.ocx - though it may have started with a different file name. I'm able to rename it, oddly enough.  To be clear, the drive is currently plugged in externally. So I can boot the computer, plug this drive in afterward, and immediately attempt to delete. "File in use" box reads "the action can't be completed because the file is open in another program".  I'd format at this point, but it's my white whale, and I have to know if Adobe has inserted some nasty little registry hack - or whatever it is - making this impossible.  Since I'm sure it'll come up, I've taken ownership of the file - and this was the trick preventing me from deleting anything else on the drive - full rights on the file permissions, you name it, I've fiddled with the file itself.   I'm about to try uninstalling flash from the system drive, in case that aligns the planets properly. Sometimes I wish I were less stubborn, and could just format already.

I'm looking for a solution to write-protect the contents of a USB key. The idea is to prevent its contents from being inadvertently removed by the user or changed by malicious programs -- not to restrict the re-cycling of the key for something else.  Here is a summary of my findings so far:   Some keys have a switch which makes them read-only. Unfortunately this is not always the case.  With a FAT32 filesystem the only solution seems to be setting the files "read-only". But this protection is too weak. There is a slightly stronger write-protection available for NTFS, which can be achieved by removing write privileges from "All Users" it will make the files read-only to every account, except "Administrator". Formatting the disk as UDF makes it read-only under Windows&nbsp;XP SP3, but read-write in Windows&nbsp;Vista, Windows&nbsp;7, Linux and Mac&nbsp;OS&nbsp;X. Formatting as ISO9660/CDFS makes it read-only under Linux and Mac&nbsp;OS&nbsp;X, but unfortunately the contents are not readable anymore from Windows. With microcontroller-specific software is possible (if supported by the chip) to re-partition the key so it displays for example a write-protected and a read-write partition. The problem is that it is very confusing for the users: the write-protected partition can appear as a CD-ROM drive (which it is not), after insertion some drivers are apparently installed on the computer (in fact they are not really drivers), and it can lead to prompting for reboot. Besides, this solution cannot be applied universally because it requires knowing which chip is used in the drive, and the existence of publicly available tools to re-program the device.  John Reasor mentions utilities able to fill all free space on the device, making it impossible to create new files (see below).   Does there exist a general solution to store non-modifiable contents on a USB key?   It protects the contents from modifications typically done from the shell (e.g. delete, rename, move) or from the files and folders being modified by a standard applications (e.g. save-as) It should work with most of the devices The user can still re-format the device into a regular key to re-cycle it for another usage (for example, with )
