SanDisk Cruzer Blade 16GB write protected error

I’m having exately the same problem, my Cruzer Edge 16GB became read-only from the nothing. 

No resolutions yet ? 

Brazilian Thanks.

“No resolutions yet?”

Have you tried writing to it after booting to Safe Mode?

Have you tried detailing what your environment is?  ie what OS are you running, Linux or Windows?  XP or 7?  32 bit or 64 bit?what other apps are you running, especially what anti-virus and anti-malware?  Are you using a personal pc or a school pc?  Schools and corporations can impose write limitations on their pcs.

If a personal pc and WIndows XP or 7 have you tried this option:

1. Open Start Menu 

2. Run, type regedit and press Enter, this will open the registry editor. 

3. Navigate to the following path: 
     HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies 
4. Double click the key WriteProtect in the right pane and set the value to 0 In the Value Data Box and press OK button 
5. Exit Registry 
6. Remove your Blade

7. Reboot your pc.

8. Re-connect your Blade to your pc. 

Without knowing what your running and what you’ve tried it’s hard to suggest a solution.

i’ve already did it and don’t worked for my cruzer.

thanks

and i tried programs like HS Utility repair, uRescue, but no one works with my pendrive, says pendrive not found. The same error appears at Windows XP and 7.

Just to be clear, you tried booting to Safe Mode then writing to the Cruzer?

BTW A “pendrive not found” is different from a “pendrive write protected”.  In order to be write protected the pendrive is found by the OS.

Guys please help me I’m stuck here. I really need to use my memory drive. I can’t delete or cut or format the drive. I have test it in so many computers (windows, Linux &…) Please give me a solution

please!! please!!

Friend, the utility program who should format the pendrive says pendrive not found. I can see what is on the pendrive, but i can’t format, add new files and remove files, says ‘Your pendrive is write-protected’.

I’ve tried to boot at secure mode and don’t worked. 

Thanks.

I’m still confused RickDan.

The utility to format the drive runs under Windows?  Or is it a standalone utility that boots from a CD or USB?  If the utility runs under Windows and Windows can read the drive it could mean that the utility doesn’t support removable drives or Windows security is preventing it from seeing the drive.

As for “I’ve tried to boot at secure mode and don’t worked.” does that mean you couldn’t boot to Safe mode or you booted to it and the format utility didn’t work.

Another option might be to try a utility like Parted Magic to format the drive or at least see if it can write to the drive.  If it can write to the drive the problem is Windows.  If it can’t the problem is the drive.

Friends,

I have the same error on my 8 gb cruzer edge and tried 2 format it with windows(7,xp)linux(debian,ubuntu,redhat) and tools like Gparted…, but no use… In linux it can be mounted only as a ‘read only file system’…Wasted so many days trying to fix it…:frowning:

Any help would be greatly appreciated

Thanking You

guys there is really no way of fixing this ive tried everything from fileshredding to uninstalling the only thing you can do is probably call sandisk and see if they can send you one or you can ask you to wipe yours it may cost you unless you have a warranty on it but thats what i di and there gonna send me one around 2 weeks :cry:

Who posts to a USB Flash Drive forum? I just registered to join in the fun. How many of these do people get through? Anyway it’s loquacious & erudite, so.

I think luckaduck’s right for the wrong reason. Fat32, Dell, Vista, forget it. The drive will store the data it says, less a small amount for who knows why. Here it is: the drive has two write caching policies : (a) pull it out quick; (b) ask Windows to let you pull it out. Default is “Ask Windows” - see that little green tick thing in the System Tray? (If you don’t believe me, go Computer>F-drive>Properties>Hardware>Sandisk Cruzer Blade Device>Properties>Policies). So, that’s how it is, you forget to ask permissionle, pull it out (you might as well marry the thing), no green tick, it says"No way" and uses write protect to stop your barbarity.

Try this: Computer>F-drive (or whatever - call it Mabel if you want)>Properties>Sharing>Advanced Sharing>Share this folder>Permissions>Everyone>Full Control>Apply>OK>Apply>OK (it’s a different box)>Close. Then ask Windows to let you take it out. Then: in Windows run a mega-destructor data erasure program like East Tec or Cyber Scrub (hint: 15 day free trial). When you’re done, leave it for a while, then stick the drive back in, and - yes? No? If the mofo can remember it’s write- protected after your whole system’s been East Tec-ed, it’s more human than I am.

I can’t promise it’ll work, but I’ve done it, and it’s worth a go.

The weird stuff people want you to do - I’m surprised nobody wants to stick a needle in the hole and get at the little write protect man.

Don’t format, don’t mess about with drive recovery programs, and DON’T BLAME THE PRODUCT!

Good luck

Here it is: the drive has two write caching policies : (a) pull it out quick; (b) ask Windows to let you pull it out. Default is "Ask Windows”"

Wrong.  The default is (a), on Windows XP, Vista, 7-32bit & 7-64bit. 

see that little green tick thing in the System Tray?”

Yes, and it’s present when option (a) is used. 

But thanks for posting. :laughing:

Well, if (a) is the default, how is it that drives I’ve never modified both came out of the packaging set to “Optimize for performance”, i.e. I have to stop them using the system tray instruction before I remove them?

All I can say is that I had the problem myself and what I described solved it. It could just be luck or coincidence.

If you follow the steps you posted:

(If you don’t believe me, go Computer>F-drive>Properties>Hardware>Sandisk Cruzer Blade Device>Properties>Policies

you will see on the Policies tab “Removal policy” and under that heading you will see “Quick removal (default)” and under that option “Better performance”.  The word “default” is put there by Windows and doesn’t change if the “Better performance” option is selected.

So, that’s how it is, you forget to ask permissionle, pull it out (you might as well marry the thing), no green tick, it says"No way" and uses write protect to stop your barbarity.”

Unfortunately if the Better performance option is used and the USB is simply yanked out, it doesn’t say “No way”, it doesn’t say anything.  At least not on my machines.  And what is this “write protect” you refer to?  Is “it” a Windows thing, a hardware thing, …?

Don’t format, don’t mess about with drive recovery programs, and DON’T BLAME THE PRODUCT!

Now that is something I agree with. :smiley:

My personal theory as to the USB drives getting screwed up is they are used on machines that have the “Better performance” option enabled, they are indeed yanked out without using the Safe Removal option and the FAT on the USB drive gets screwed up if they have written to the USB drive.  The files on the drives and the FAT are out of sync.

do you know what’s causing this??  i had this problem wind a cruzer edge 16GB that I returned to the shop, then they gave me a cruzer blade 16GB, 3 days later is write protected as well!! iam trying everything and nothing seems too work! the only thing that changed in my computer last week was some win7 optional updates that I installed… I have no virus, spyware or malware!! scanned dozen of times. Iam going to return the second flash drive but iam afraid it happens again…

a little help here…

Are you using it/them with Windows 7 and Homegroup access?

windows 7 yes, homegroup no, been using them for a few months.I have another cruzer blade 8GB and this never hapened

The only time I have had a USB stick that was writable suddenly not be was when I used it on Windows 7 and somehow it became part of the machine’s Homegroup and I either clicked on the drive’s option to make it Read Only or that was a Windows 7 default.  Once I changed the Sharing setting the stick was writable again.

The problem was not the stick’s fault, it was a pc, or noobie’s, fault.

However, there are other things that can protect a USB stick’s files.  A business’s/university’s/school’s security settings.  A machine’s user settings.  A machine’s AV or other app’s security settings.  Some of these things can be circumvented by booting the machine to Safe Mode.

Here same problem to SanDisk Cruzer Edge 16GB write protected error

I tried solve this problem until now.

I tried many ways on XP,  win 7, vista and Apple MAC.

Tried used Partition, format, Regedit, Low format, Unlock s/w and utility.

almost a week when i have time tried solve this problem.

i think i tried almost all when i got and found information from internet .

also i have 2 more SanDisk Cruzer Edge 16GB but working well

please help me

Thanks

Professor SanDisk,

a quick search on the internet will bring up hundreds of results of people with the same read only problem. I am an IT expert and my 16GB Cruzer Blade made it to 24 hours of use before it to went into a ‘read-only’ lock.

I stopped buying SanDisk products after the catastrophic failure of my 4GB Extreme III SD card.

The current 16 GB Cruzer blade was a gift.

Either post a solution to this problem or post a procedure where we can exchange the unit or receive a refund.

I rather suspect the SanDisk chinese production is biased towards quantity rather than quality.

Regards
