SanDisk Cruzer Blade 16GB write protected error

Its because most of the uasers with faulty devices don’t know what to do and dont know to post in your forum.”

A good point.  

Iam a computer parts sellerand i know how many i got returned back to my shop

How many do you sell in a month’s time and how many of those get returned?

Read that less than 1% of thiese things fail?

have had a 32gb micro sdhc for a week, suddenly came up write protected?

tried all sorts of things,

eventually by loading it into a cheap camera I formatted it.

Back into PC! Write protected! 

well I got the **bleep** thing for £10, so cheap I bought two, loaded the new, unused one in, and straight away, straight out of the box… write protected!.

less than 1% eh? and why are they so cheap? 

Thank you for posting your experience.  I’ve said all along that the problem was a Windows problem rather than a hardware problem.  If it was a hardware problem you wouldn’t have been able to format it even in an expensive camera.

Hi, I have a Cruzer and I mainly use it for my xbox 360 since I dont have that much storage on it by itself. So I put it into my computer (I dont really know why…) but when I took it out and tried to use it back for my xbox 360, when I tried to copy a file over onto it it said that it cannot do it because there is write protect on it. I dont know if this matters but I have MS Windows 7 Home Premium 32-bit. So, is it possible to get write protection off of it?

Do you have a cheap camera?  :smiley:

Referring to a poster’s comment 2 or 3 above yours.

Hi, I had the same problem and tried everything suggested but nothing worked.

Finally I found the answer was to use a Flash drive tester - in Destructive write test mode. You will lose any data not saved but you can now re-format the drive. This is the link to a free program,

Hope this helps,

Thanks Graham.

Does the formatting remove the write protection when the drive is used back in a pc?  It was noted in another recent post that the drive could be formatted in a cheap camera but it was still write protected when put back in the pc.

Works fine on my laptop now, tried everything else including registry hacks this is the only thing that worked.

Thanks for the follow up, gdauphin.  Hopefully this helps out many of the others with problems.

How you did that? Even this software says it’s write protected. I tryed this and HD Tune Pro!!

I Just bought two 16gb sanddisk flashdrives and both of them are with this problem! I bought both on Amazon.

Hi, I am propbably 1 of the 1% who have problems with my Cruzer blade 16gb. It is also write protected on its own accord.

This happened maybe a month or so ago & I finally decided to look for a solution or if someone else has this problem. Well it seems I am not the only one.

I do believe alot of people may have this problem, but are not inclined to search the web for a solution or thinking they did something wrong.

The check flash solution did not work for me. It states the obvious: your drive is write protected, remove the write protection first.

We need some customer service & a solution to your product’s fault.

It is no use blaming Windows. It is a Sandisk problem.

Please provide a solution. I am looking forward to great customer service & a speedy solution to this problem some of us experience with your product.

Return it or contact SanDisk directly for a warranty replacement as suggested above.

That’s not a suggestion. That’s just prolonging a problem that you need to actually fix.

Well, you can do nothing or you can continue to complain but I can assure you neither will solve your problem. The options TapeWorm gave are the only two options that work.

Only two options that work? That’s sad. Either 1.return it, or 2. talk to customer service, who’ll, in the end, tell you to return it. Great options.

Sandisk needs to figure this problem out. My mother ordered a sandisk camera sd card usb stick, only to have it stop working after 2 uses.

Sorry, two different types of “returns”.  One means “return” it to where you bought it, the other means contact SanDisk who will have you “return” it to them.

As with most problems if they are easy to reproduce they are easy to determine a fix.  This write protect problem is not reproducable.  Many people experience it, on different machines and different OSs and different uses but not everybody and not all the time.  It could be static electricity, low power voltage from the power supply, heat, bent wires, broken wires, dust.  Anything.  hard to fix if you don’t know what to fix.
