Grant/reject access to USB thumb drive

I am building an information security simulation model using LabVIEW
and would like to grant/reject read/write accesses to the removable
media such as USB thumb drives. I would appreciate if someone can
tell me how this can be achieved under LabVIEW environment.
Thanks in advance.

Hello Belur,
LabVIEW is capable of modifying access rights to files using the VI on
the controls palette found at File I/O >> Advanced File Functions >>
Access Rights. The "http://sine.ni.com/apps/we/niepd_web_display.DISPLAY_EPD4?p_guid=B123AE0CBACD111EE034080020E74861&p...
example shows how to use this VI
to modify file access rights.
If you need more complex security functions, you will probably need to
access third-party DLLs suited for your specific application.
If this does not help, please post more information about the access
controls that you are trying to implement, and which version of
LabVIEW you are using.
Have a good day,
Kyle

I need a way to get usb thumb-drive securely recognized as a apple keyboard

I posted this question over at Developer Discussions also, just to get more eyes on it, not to be disruptive.
So, I would like to utilize a maximum-length Admin. password (255 characters?) without having to manually type it in each time I login, install/update software, or for any other reason. The perfect situation would be some type of script or software installation onto a USB pen drive (2 gig sony)which is inserted into the macbook (via usb) when the Leopard Login screen appears. It logs me in, then, afterwards, it creates a clickable icon on the desktop that achieves the same goal (entering a long admin password securely). And all of the above is achieved using the built-in security of Keychain access, without having to continuously mount and unmount the drive.
Searching google produces many expensive products that do not fit: Securikey, omnikey, smart cards, tokends, and on and on. They seem to have figured this out at microsoft - not that it matters much, except that it appears to be possible.
One problem is that a USB thumb drive is not mounted until after login, it seems, but, I plugged in a friend's usb apple keyboard from the year 2000 and was able to type in my password at login. And, an email reply elsewhere suggested writing a daemon (that constantly runs in the background of the operating system) that could recognize the drive and accept a script from it that inputs the password and executes the 'enter' command.
I don't know how to write daemons yet, but I can stumble around a bit with bash and applescripts, and I can copy any Xcode project out of a book and make it run properly. I'm a beginner.
This project might create security issues for my operating system, but I'm really not concerned about that because this is a computer I don't rely on and can safely perform experiments on. And I would like to use this as an opportunity to learn - so I'm going to give it a whirl anyway - unless someone has already accomplished something similar. In that case, why reinvent the wheel and plug it into the wall, eh?
Basically I am asking for help. Any suggestions would be greatly appreciated.

You don't need to get deep into programming to do much of this.
launchd, the background process that's responsible for launching most of the background processes on your machine, has the ability to launch a script based on disk mount events.
StartOnMount <boolean>
This optional key causes the job to be started every time a filesystem is
mounted.
So you could create a LaunchDaemon script that watches for a disk mount. When a disk is inserted your script is fired off. You'd need to perform some verification to ensure the disk is, indeed, your USB stick and not some other device, then it can trigger the rest of the login process. Off hand I'd look to osascript to run an AppleScript-based keystroke, but there may be other ways, too.
One big question relates to securing your password. Clearly you can't store it in the script, so you'd have to read it from somewhere. You also can't store it on the USB stick unless you somehow encrypt it (otherwise someone can just look at the files on the USB stick and get your password), but AppleScript can use the keychain, too, although I'm not sure what keys would be available prior to login, so it requires some experimentation.

Using USB thumb drive with Parallels and Microsoft Windows XP

I installed Parallels 3.0 because I need to use a few windows applications for work. I am currently unable to find the USB thumb drive when I plug it into the USB port. It is connected and is selected, but I can't figure out how to access it. I check in "My Computer" just like I would on a PC, but the thumb drive is not listed. Any suggestions.
Macbook with Leopard
Thanks.
Jon

You're right, it should show up under My Computer. You may want to post your question over on the Parallels forums: http://forums.parallels.com as they're more geared toward the issue since Parallels is not an Apple product.

Format a New USB Thumb Drive

I have a new USB thumb drive I just picked up and I was able to mount in to my Linux machine fine:

Now I would like to wipe and reformat the entire drive since I backed up the data. However before I reformat the drive, how can I set the label name into the format command while formatting as fat32? I don't need to use FDISK since I am not changing anything in regards to the partition table / chunk size. I just want to format as fat32 however I don't have mkfs.msdos or mkfs.fat32 on my Arch Linux system. I checked the Wiki and didn't find anything nor did any search thread results.
Anyone know what package I need to format fat32 & how I can set a label name so when it's mounted, I can see a specific name for the drive?

me spots some inconsistencies. i'd bet if you used gparted instead, it'd warn you and say something like "create DOS Partition table first" or somesuch.
i dunno, this is the one area i like the wipe-my-ass-for-me bloat , could be worth a try.

When I plug in my USB Thumb drive (PNY 8Gb) the MacBook Pro does not see it, nothing happens. Is there something else I need to do?

When I plug a PNY 8Gb USB thumb drive, nothing happens and the MacBook Pro can't see it. Is there something I need to do?

If you are looking for it in Desktop, it's normal that you feel like your Mac doesn't detect it. By default, OS X doesn't show external drives in Desktop, so you have to access to them from Finder. To do it, open a Finder window and choose your external drive in the Finder sidebar, under "Devices".
If you want to show the external disk in Desktop, open a Finder window, go to the Finder menu (on the menu bar) > Preferences > General, and mark "External drives"

How to create a Mac OS X Lion USB thumb drive installation bootable drive on a brand new Macbook???

Hi,
As Apple have decided not to give with new laptops USB thumb drives for installation of OS X Lion (as they did with Snow Leopard), since people on the go might not have access to high speed internet when the system crashes, plenty of tutorials have surfaced about "How to Make a Bootable Mac OS X Lion USB Install Key"
Such as
http://www.iclarified.com/entry/index.php?enid=16149
http://www.pcmag.com/article2/0,2817,2389178,00.asp
These all assume you have upgraded to Lion from Snow Leopard thus purchasing the Lion on the App Store.
Any ideas what people who have purchased brand new Mabooks do? As the system comes preloaded with the OS X Lion and it's not considered purchased on the App store.
I think Apple's new policy to charge customers $69 for this thumb drive is wrong and outrageous since the price of the laptop includes a license for the OS!
Thanks,
Guy.

Sync USB thumb drive as if iPod?

Summary:
I want to use one of my USB thumb drives as a music library that can work on my car's audio system. What is the easiest way to do this?
Background:
My brand new car stereo can play music off of an iPod. This is convenient, but I don't want to just leave my ipod touch in my car. My car stereo can also play music right off of a USB thumbdrive. So is there a way to sync all my play lists on my USB drive? This way I can just leave it in my car and not worry about theft, my ipod melting in the sun, etc.
I don't think iTunes can do this, so maybe there's a script somewhere? It will have to prune out the m4p files since obviously I can't authorize my car stereo to play them... (grrr DRM...)
Considered Solutions:
1) Obviously, I can just copy files over manually, and write a perl script to remove .m4p files. But I'd like to get playlists...
2) I could get the 32 gb USB drive I saw, which can hold all my stuff, but then that's too much data to browse while driving my car.
3) I could manually export each playlist, and write my script to parse and copy those files... but that would still require me to manually export the playlists (so it's not automatic).
4) I could just try to remember to bring my ipod with me whenever i go somewhere, but i'd rather just leave a usb stick in my car. Then there's nothing to worry about, and nothing to forget.
5) I could plug in my ipod, and see if there's a way to access it's file system and then just mirror the usb drive off of the ipod... but i looks like the ipod is hidden in the file directory.
6) If any Apple people see this, I'd appreciate them thinking about allowing iTunes to treat a USB drive as a limited iPod.

I have the same issue. I have not had a problem copying album folders to the thumb drive from the itunes library but the problem I have is that most of my files are not in the mp3 format but in lossless or AAC.
I have been selecting the tunes I want and, after changing my import settings to high level mp3, selecting "create MP3 version" under the advanced menu. The issue is not wanting to duplicate my library. If I were to burn that selection of non-MP3 files to a CD specifying a MP3 disk I don't get the duplicates. Burning the disks and then copying the files from there to the stick works but you have to put in the album folders manually and that is a lot of disks to burn for an 8G stick. I tried using DVD's but you can only burn a data disk in that format and no MP3 conversion.
A lot of new cars come with the USB option and the usb flash drives are cheap. There will be a rapidly increasing number of people looking to get a playlist to MP3 format onto flash drives. Apple needs to give us a tweak here.

SunRay 3.1 CAM with USB Thumb Drive

Dear SunRay Forum,
I installed Solaris 10 06/06 and latest OS patches in my SF280R server. On top of that, i installed SRSS 3.1 and patch.
I want to access to my thumb drive from my SR150( CAM Mode ). Initially, i had inserted thumb drive and cannot see my drive. So i followed this blog "http://blogs.sun.com/ThinkThin/entry/cam_mass_storage_workaround#comment-11" to enable USB drive. After gone through the blog i can mount thumb drive( ls -l /tmp/SUNWut/mnt/utcu0/ ). Before i left office, i had shutdown my server.
This morning, i powered up the server and found out that, the SR150 can't mount the thumb drive. I also read one of the mailing list mentioned to check any NIC interface error but from my server i don't see any error.
Note: The same problem happens in my Solaris 10 11/06 release.
Appreciate, if anyone can guide me to solve the problem.
Do let me know, if you require any further information.

USB Thumb Drive Not Mounting With Mavericks

I have several Thumb drives (FAT32) that no longer mount on my iMac running Mavericks.
The thumb drives do not show up in finder nor do they show up in disc utilities.
The USB bus still seems to work since other USB devices seem to connect to it, but none
of the thumb drives do. I have done an SMC and PRAM reset with no luck. I do not have
TUXERA nor NTFS-3G so nothing their to disable.
I do have a Mac Mini running Mountain Lion and all thumb drives do work with that.
Out of ideas here.

But given that other USB devices work here — what sorts of other USB devices?
I have 2 external hard drives that work on the very same USB port and an external blu-ray drive as well.
Are there any add-on anti-virus or anti-malware "tools" installed?
None. Never have.
To check the USB bus, remove all hubs and all other external USB devices from this Mac, reboot, connect one of the thumb drives directly to the Mac, and try again.
Everything re-connected except for the thumb drives. External hard drive and Blu-ray drives popped right up but no USB flash drives.
Try a different and newly-created login, and see if the flash drives work there.
I used the Guest login and the same thing, everything works except the Thumb drives.
To check the local OS X installation, see if booting this Mac from the recovery partition (if one is present)
None is present.
or booted from another (external) OS X disk allows access to the thumb drives.
I have en extern HD that is blank, but I do not know how to install Mavericks on it then run it.
Is there anything in common among these failing USB disks? Same brand and model? Or a mixture of different thumb drives?
They are all FAT32, other than that no I have Cruzer, Kingston and PNY brands. 2GB 4GB and 16GB.
Are the OS X systems involved both similar configurations, or are they very different versions?
Mac Mini is Mountain Lion and has no issues with the thumb drive.
Intel iMac is Mavericks and my Mac Book Pro is Mavericks. Neither one of them can mount my USB sticks.
Thanks for your complete reply, you had some items that I did not try but unfortunately it did not help yet.

Prepare an usb thumb drive, to boot windows 7 or 8 in UEFI mode

Purpose of this post:
Prepare an usb thumb drive, to boot windows 7 in UEFI mode and install the system in pure UEFI mode.
Why am I writing this:
I had a hard time finding out how to make a custom installation of windows 7 in pure UEFI mode, and avoid using the factory restore disks. After hours of research, experiments etc I finally got the point and found a solution. And I'm happy to share my research with you. I hope this will be of help. If something is not clear, or more information is needed, I will be glad to explain things further.
History:
As most of you already know, BIOS was developed for PC in early eighties and has remained unchanged in recent years. But, since 2000, Intel started working on a new firmware interface, called Extensible Firmware Interface, abbreviated EFI. And since 2005 United EFI Forum has been handling the responsibility for development, management and promotion of UEFI specifications. Bigger companies like Intel, AMD, Microsoft and Dell have already started to bring out their products in accordance to UEFI standards which has more stable, secure and easier to use interface.
How does UEFI works (in a nutshell):
Once you power on the UEFI based PC, the Pre-EFI is executed which initializes only the CPU, memory and the chipset. This followed by Driver Execution Environment (DEX) where other hardware is initialized.
Advantages of UEFI:
    It can integrate various drivers this will not require to load during booting so saves time.
   PC can connect to network without OS.
   Also integrated drivers allow rendering GUI based control panel which out dates the old school bluish BIOS screen.
   Not all the installed hard drives are scanned as boot drive is set during the installation of OS in UFFI.
   Applications like anti-virus and diagnostic tools can be stored on virtually any non-volatile storage devices attached to a PC.
For a system to boot and install in UEFI the partition table of the HDD should be GPT (GUID Partition Table), not the old school MBR (master boot record). GPT has many advantages, can have virtually an unlimited number of partitions (windows will allow only 128) and impressively big partitions.
Since UEFI has a lot of advantages why not having a system install and boot in UEFI mode? AFAIK new Lenovo notebooks/netbooks are UEFI capable and OS’s are already installed in pure UEFI mode.
So, let’s go now to the point. Do you want to have more control over your HDD? Let say, you have a 320GB HDD and you have divided it in two partitions, one of 50GB, for your Windows 7, and the remaining for your data. If something goes wrong and you need to restore your system to factory default, with the recovery disks, it will wipe your partition scheme, set the system to default and this way your data will be lost.
You may want to make a “vanilla” installation of windows from a USB thumb drive and avoid using factory recovery disks. Now here things get complicated. A standard preparation of the USB with Microsoft’s software (Windows 7 USB/DVD Download Tool), or other tools, will give you a bios installation, not a UEFI one. So for the system to boot, you will need to change some settings in bios, and changing it from UEFI to legacy bios. The installation will prepare the HDD in MBR partition table, and you will lose all the advantages of UEFI, described above.
Now this can be avoided, by properly preparing an USB to boot and install in UEFI mode. Here are the steps:
Step by step tutorial:
1.   In a windows computer, download a legal copy (although trial) of the windows 7 os. You can do this from here: http://www.mydigitallife.info/official-windows-7-sp1-iso-from-digital-river/
Be sure to download the same version that came preinstalled in your computer. For example, if you have a Lenovo x120e, with a Windows 7 professional, 64bit, download an iso image of the Windows 7 professional 64bit.
2.   Once downloaded burn the iso to a USB thumb (at least 4GB) using Windows 7 USB/DVD Download Tool.
3.   After preparing this, create a folder on your computer, name it whatever (i.e. W7pro64bit). Go to the root of your USB
and select all the files and folders there (9 in total) copy, and paste to your folder you created, W7pro64bit.
4.   Using windows format the usb again in FAT32. Windows 7 USB/DVD Download tool, formats it in NTFS. We need a FAT32 formatted disk to achieve our goal. Formating again the USB in FAT32 will not touch the MBR of the USB thumbdrive. And after copying back the files (see step 6) the USB will still be bootable. (nice, and simple, isn't it?)
5.   Now go to the folder W7pro64bit and do the following:
a.   Browse to W7pro64bit\sources\ and open install.wim file. It’s a big file, and can be opened as an archive with 7zip (free software). Do not extract it, do not modify it, just browse the file with 7zip. Just to be sure you do not mess with that file, you can copy it somewhere else in your computer, and than procede.
b.   Browse this file (install.wim) to \1\Windows\Boot\EFI\ and locate the file bootmgfw.efi. Do not move, delete it, but just drag that file to the desktop. (if you have copied the file install.wim to another place in your computer, than you are safely do whatever you want with that file ) Close the 7zip program to release the install.wim file.
c.   Rename the file you just copied to the desktop from bootmgfw.efi to bootx64.efi.
d.   Now go back to w7pro64bit folder and browse \efi\Microsoft. Form there copy the folder boot and paste it one level up, on the folder: \efi. It will look like this: \efi\boot.
e.   Now copy the file you saved on your desktop and renamed (bootx64.efi) to \efi\boot (inside the boot folder you copied on step 5d
6.   Now go to the root of the folder W7pro64bit and select all folders and files (9 in total) copy, and paste all those files back to your USB thumb drive. (see step 4 for more info)
7.   Go to the computer that you are going to reinstall, and before restarting it, use the program ABR (activation backup and restore) to backup the license of your windows os. (use google to find ABR). Advanced Tokens Manager (ATM ) is great too. This link may be of help: Backup and restore W7 activation. After the program finishes its magic, it will create a few files inside the folder where the program itself reside. Copy these files to a new folder in your usb. Rename it to ABR so you will quickly find it later. (if you decide to use ATM, the procedure may be a little different. But you are smart enough to figure out how to use it)
8.   Backup to an external storage all your data before continuing.(reminder: are you sure you saved the license as explained in step 7, to a safe place? To a external drive, to another computer? If you are sure, than go on with step 9)
9.   Now restart your laptop, and enter your bios settings. Go to the boot settings, and set the computer to boot in UEFI only. Not both, not UEFI first, or legacy, BUT UEFI only. Save and restart.
10.   Press f12 (or the corresponding key for your machine) to choose the boot device and chose to start from the USB thumb drive with your windows 7 pro 64 bit.
11.   If everything is done correctly, your computer will boot from the USB.
12.   Follow the wizard and choose a custom install, not upgrade. At the disk partition window delete all the partition you see there until you have only one unallocated space.
13.   Select it, and click next to install windows, without making partition in this point. The installer will create a GPT partition table not a MBR since the USB booted in UEFI mode.
14.   Immediately after the first restart remove your USB thumb, and the installation will continue from the HDD. Wait until installation finishes.
15.   When you will be finally on your desktop, on the installed OS plug your USB go to the ABR folder and click on restore.exe. It will restore your license and your copy of windows will be activated.
16.   Now you can go in computer management/disk management and shrink the HDD to create your partitioning scheme. Make sure to leave enough space to your windows os. (30gb or more for extra programs you will install at your choice)
17.      Download from lenovo.com thinkvantage system update and update your system. Windows update too can install all the necessary drivers, if you need only basic drivers support.
Note: if tvsu will fail to work, see this:
http://forums.lenovo.com/t5/ThinkVantage-Technologies/ThinkVantage-System-Update-Servers-down-the-wh...
It may look a looong tutorial, but once you do this for the first time, it will look a piece of cake.
Final words:
From now on, you can install windows 7 in UEFI mode with your special USB without changing your partition scheme anymore. If you have a data partition beside your os partition (see the example above), when you reinstall the system using your USB thumb drive, at the disk partition window chose the partition where windows is installed, delete it, and reinstall windows to the unformatted area. Your partition with your data will be intact and the installation will automatically mount your data partition to the system. And, all the scope of this procedure, you will always have a pure UEFI installation of the system, with all its benefits.
Have fun!

In the case of Windows 8, I needed to copy the files away, reformat my USB key as FAT32 and copy the files back, and viola I was able to boot from my USB install media with the BIOS set to only boot UEFI. From there, there rest was easy (for Windows 8, the copying and renaming is not necessary, the key is having a FAT32 partition on the USB media, rather than an NTFS one; the EFI files are already in the right location).
Thank you again good sir.
You are welcome... and I'm happy that the change of the file system helps with windows 8 too. Thanks for confirming that.

Using a usb thumb drive with a mac

So, I'm a recent windows user and when using a USB thumb drive, if you erased something, it would automatically update the thumb drive and show the right amount of free space.
I've noticed with the mac, if you delete an item, it doesn't update, and you need to go into disk utility and format in order to show the appropriate amount of free space.
Is there an easier way to do this?
I searched for a few minutes on this topic, but couldn't seem to find anything. All apologies if I missed it.

Choose Empty Trash from the Finder menu, or from the menu which appears when you control-click or click and hold on the Trash icon in the Dock.

How can I create a Lion USB Thumb Drive with the 11E2068 build?

It seems that the Lion build from the Mac App Store is not compatible with my Macbook Pro Retina 15''. It's seems I would need the the build 11E2068 for my USB thumb drive to work properly.
I don't want to go through the internet recovery and loose 8 hours.
Is there anyway for my to get that build(11E2068) on my USB thumb drive?
Thanks,

keg55's given you article that allows you to capture the installer. These are the critical portions:
Once that data has been downloaded, Lion Recovery restarts your Mac, immediately installs the OS, and then deletes the installer data. The trick is to interrupt that process—safely—so you can grab the installer data and keep it. Here are the steps to take:
IMO, Apple needs to rethink this process. Unless users with machines that had Lion preinstalled, like yourself, let Apple know this process is terrible, they'll not change their minds.
7. IMPORTANT: Monitor the download’s progress. As the progress bar gets near the end, get ready, because once the status reads About 0 seconds remaining, the progress bar will disappear, the installer will spend a minute or two cleaning up, and then your Mac will restart. As soon as the screen goes dark, unplug your external drive. If you wait too long, your Mac will boot into the Mac OS X installer on that drive, starting the installation process. Interrupting that process can leave your Mac unable to install OS X unless you restart it and—I’m not joking—zap PRAM.

How to dual boot from usb thumb drive in lenovo x1 carbon

How can I boot Lenovo x1 carbon 2014 from an USB thumb drive? It has Windows 8.1. And I have tried disabling secure boot in bios setting. And set usb drive to boot order 1. But that still does not work.

I use the
Windows USB/DVD Download Tool too to create the usb thumb drive. And I use the tool to copy the iso file there.
And when I use that drive on an older laptop runs windows 7. it works.

USB thumb drive crashes MBP and PowerBook G4

Hi!
I have a USB thumb drive. It mounts on the Desktop (as two drives, which is not strange because it has both an internal 6 MB of memory and a 2GB SD card) and I can open them. But if I attempt to copy a file either to or from the drive, the Finder hangs forever.
This problem exists both on a shiny new MacBook Pro with 10.4.7, and a PowerBook G4 with 10.3---in either case, I must hard-reboot the machine.
DiskUtility says that the drive checks out OK.
Any thoughts? I tried reformatting the thumb drive, which worked temporarily; but when I added a file to the drive on another machine and tried to transfer it to the Mac, the thing hangs Finder again.
I don't have any problems with the drive on PCs, and I don't have the problem with other USB drives on the Mac.
Xcott

It sounds like the file system is corrupt. I am assuming it's FAT32. I would reformat the drive partitions on a Windows machine and see if that helps.
Also, because it's a dual, you might want to make certain that you do not plug it into a hub or a keyboard but directly into your Mac's USB host port. It may need additional power...
Good Luck!
