Write protected flash drives
I have a macbook pro with OS Lion. I have 3 usb flashdrives and all of them have suddenly become write protected. There is no switch on the stick. I believe the problem started after I bootcamped my computer and began running windows 7. I was trying to transfer files from the windows side to the mac side and now the flashdrive cannot be opened from either, or any other computer. Any ideas to get it working again? It's an 8g SanDisk cruzer facet flashdrive.
Some flash drives have a failure mode in which they are irreversibly write-locked by the internal controller when it detects a write error. If you can't erase the drive in Disk Utility on any computer, that's almost certainly what has happened.

Password protecting a Flash Drive?
When I plug in my FlashDrive it opens up a Disk Image, I was wondering if it is at all possible to set up that Disk Image as a Password Protected disk image?
So when I insert the Flash Drive it will prompt me for a password and then open. I am starting up a small company and I would to keep all my confidential files on a Password Protected Flash Drive.
I know how to set up a password protected disk image using disk utility. But Disk Utility wont let me put a password on the disk image that automatically opens when inserting the flash drive, I have tried reformatting the flash drive, etc. but can't seem to get it to work.
The closest I've gotten is putting a .dmg file on the flash drive and then after opening the drive, open the .dmg file. Which would then prompt me for a password and open a new disk image. but I would like it a little less troublesome.
Please some one tell me if this is possible or not and How to do this?? Thanks
there are no built in tools to do that. the best you can do using built in tools is to make an encrypted disk image and put that on your flash drive. but you say you don't want that. the only other option would be a 3rd party full disk encryption tool like TrueCrypt or PGP. I'm not familiar with either so you'll have to investigate that yourself.

Flash Drive won't Open after Yosemite upgrade
I recently updated my MacBook Pro 13' to OS X Yosemite. I went to pull some files off of my 16 GB SanDisk Flash Drive and I couldn't get my Mac to recognize it. I was able to open it before the upgrade. The flash drive does show up in Disk Utility, but that doesn't allow me to open it. Any help would be appreciated. Thanks!
I just had a scheduled call with apple support. I showed the representative via screen sharing the error message and the accompanying comments I receive each time when I try to open my Kingston DTVP password protected flash drive. His take on it was that the driver software of my flash drive is not compatible with Yosemite. In theory I have two options:
1 - Upgrade the driver software of my flash drive. I suspect there is only a slight chance that this is possible given that Yosemite is so new so Kingston probably doesn't have an update yet. (I will check with Kingston but their technical support is not open on weekends.) Unfortunately replacing my flash drive is not an option because my employer allows only 2 password protected models to be used on company computers.
2 - Downgrade to the previous operation system (I think it's called Mountain Lion) which I cannot do myself because I don't have TimeMachine on. If I want to do this, I most likely will have to pay for apple support.

How do I "un-write protect" USB flash drives?
I recently purchased a new computer that has Windows 8. One of my many flash/thumb drives is now suddenly marked "write-protected" when I did nothing to make it so. I found a solution listed for Windows 7. I applied it to my
own computer, however it did not change the said drive from write-protected to un-write protected. I simply want to move files to another storage device and re-format the write-protected drive for new files. How do I un-write-protect my flash/thumb
drive in the Windows 8 operating system?I ran in to the same problem but none of the instructions here helped. doing some more searching i found a different article that supplied the answer for my issue. wanted to share in case other were still having issues.
If the problem is persistent with the drive and you still can't copy files to it or format it after:-
1- You tried removing read-only permission from the drive properties
2- You tried formatting from Windows
3- You tried formatting from CMD using DISKPART
4- You tried editing the Registry solution (for WriteProtect word)
5- You tried the different free online tools like
HDD LL Format tool and HP Format Tool
Then your drive is corrupt and needs the internal chipset S/W to be flashed, i.e. repairing the USB software The
steps below will lead you to get a small program to run on your USB memory-stick which is specific to your MANUFACTURER (make) and PRODUCT (model). If you don't want to go through the headache of the manufacturer's technical support then
do it yourself as follows (which I source from here):-
1- Get Chip
Genius portable application from here which
you will use to find the VID and PID of the USB stick chip.
2- Search for the tool to repair your USB stick S/W from FlashBoot
website . Search using your VID and PID from the previous step.
3- Search on Google for the name of the application you find in the "UTILS" column in the page from step 2 and the first link on Google Results
(usually) will take you back to the FlashBoot website to download the utility to get your USB drive repaired.
It worked for me for my Kingston Data Traveler flash drive. It didn't work with all the common options for fixing the USB drive having "write protected",
but the above solution I found after hours and hours of searching online and asking my computer-geeks colleagues.
Hope this helps! -

i run into problems working with DIAdem 9.1 on Windows 2000 SP4!
The Diadem installation went quite well.
My problem:
only "Administrator" and "Power User" have the privilige to "WRITE" to the DIAdem install directory.
Trying to start Diadem as non priviliged USER I get something like:
DIAdem Configuration-Drive "C:\PROGRAM FILES\ NATIONAL INSTRUMENT\DIADEM 9.10" WRITE PROTECTED!
I installed & started DIAdem for one
time with Administrator rights. I activated the Product and exported
the KEY to a License Server. Everything works fine for Power Users an
Administrators. Only "simple" USERs are not able to start Diadem due to
missing WRITE permissions. i can't grand this permissions to
normal USERs :-(
Playing around in Registry -> "RegWriteAccessAllow" ("0","1") (DWORD) (HKEY_LOCAL_MACHINE/Software/National Instruments/Diadem/9.10),
didn't solved the problem.
I switched back to "local License" Managment (local Key files) but the Probelm persists.
thanks in advance
P.S.

Message Edited by DirkT on 08-01-2005 04:02 PMHi DirkT,
Running DIAdem with User rights has different aspects we need to look at.
1) Registry Write Access
Launching DIAdem the first time with administrative rights registers some OLE components in the registry. After this step no more Admin rights are necessary for the registry. However running DIAdem as user might result in error messages as DIAdem tries to re-register the components again. You can avoid this by setting the RegWriteAccessAllow Key to 0 (see online help under "Administrator Notes")
2) File / Folder Write Access to the DIAdem Installation Folder
DIAdem needs write access to certain files e.g. the error logfile DEM_ERRS.001 or DESKTOP.DDD when saving configurations. You may change the folder where these file are being stored and searched for to a writeable folder by launching DIAdem with the "/d<NewFolder\MyDesktop.ddd>" start parameter or by setting the environment variable "DemDDD" to that folder. Then move the following files from the DIAdem installation folder to your new writeable folder:
*.ddd
userpar.par
dem_errs.*
3) File / Folder Write Access to other Folders
There are a number of other folders that DIAdem 9.x needs write access to and which cannot be changed. All of these folders are located by default under "%ProgramFiles%\National Instruments\Shared". Currently you need your Admin to give you write access to that folder and below
For future versions of DIAdem the team is working to make running under user rights easier.
Hope that helps,

HP SimpleSave md1000h write protected! - can't initialize drive
The drive does not show up under windows explorer. Under Disk Management, the drive shows up as Not Initialized and Unallocated. When I try to initialize the drive I get "The media is write protected" Restarted the PC and also the external hard drive and the same thing.
I am running Windows 7 Professional 32 bit.You need to be an admin and also go to Control Panel --> User Accounts and turn off UAC for your account. You can set the level back later.
When in Disk Management, did you right mouse click on the new drive and select initialize?
You might have bad hardware.

When I try to use the internal hard drive as a scratch disk I get this error "unable to set scratch disk- the selected directory is on write protect or non-writable media. Any ideas on how to fix this. It only happens in fcp.
By internal, I assume you're referring to your systems (boot) drive. Is it, by chance, a partitioned dive?
Also…although many people successfully use their systems drives as scratch disks, over time you'll have better results using a dedicated drive for your media.
Good luck.

Is it possible to resize partitions on a write protected internal hard drive?
Hi everyone,
The internal hard drive on my computer has been created into two partitions, one for Mac (350 GB) and another for Windows (150 GB).
Since I rarely use Windows (only for one scientific application from CambridgeSoft), there are a lot of free space on Bootcamp (115 GB). So I would like to resize these partitions to make it the Mac partition maximized, like 450 GB, and 50 GB for Bootcamp.
And the problem is that I'm unable to do that by using Disk Utility, Stellar Management Partition, iPartition.
It says something about write protected (images below).
So are there any ways to undo the write protected or resize those partitions?
Another small question is why the total volume as seen in the second image (iPartition) is not 500 GB, but just 465 GB (50 + 415).
All comments or suggestions are highly appreciated. Thanks!
p.s. I'm the only user.To resize a Bootcamp partition you must use Bootcamp Assistant to remove the partition then create a new Bootcamp partition, or, use a 3rd party tool such as CampTune.
If you use Disk Utilities you will mess up your hard drive and it will be necessary to erase, format, and reinstall OSx and Windows again. You will lose all your data in OSx and Windows if you try to use Disk Utility to resize a Bootcamp partition.
And, 50 GB is too small for Windows, especially if you install programs and create/use data. 100GB minimum wouls likely work.
Back up all your data before messing with partition changes. -
Thumb Drive write protected after plugging into MacBook Pro
So I recently plugged my 64GB thumb drive into my MacBook Pro to transfer music from my old mac to my new one. Although as soon as I plugged into the MacBook Pro, it write protected it rendering it useless as I do not wish to use it as a storage drive for 60 songs! It is not even 1/2 full and because I plugged it into a MacBook Pro I can't use it anymore!? It is formatted to MS-FAT, and previously I had plugged it into my 09 MacBook with no problems! Please help me Make it a read and write again!!! The thumb drive is only a week old!!! There are no virus' as I have had the music on my Mac for 5 years and it has all come from the iTunes store!!!
Choose Utilities from the Finder’s Go menu, open the Disk Utility, and try running the Repair Disk command on it. If that command’s not available or doesn’t work, copy your files off and try getting a replacement.
