Re: SanDisk Cruzer Blade 16GB write protected error

If you figure it out please report back.

 

The only time I've encountered it it was a Windows 7 Sharing option set to Read Only.  An easy problem to fix.  But when it carries over difference OSs it's a different problem and no idea as to the solution, or the cause.

My 16GB SanDisk Cruzer locked up (going into "write protected" mode) in the middle of a large file copy.  I have XP

and the flash drive has never been hooked up to a Windows 7 system.

 

I'm guessing that this is some sort of hardware glitch that SanDisk doesn't want to admit to for some reason, probably because they don't have a fix for it and/or don't know exactly what is causing it.

"I'm guessing that this is some sort of hardware glitch "

 

While I suppose it's possible I'm still leaning toward a software problem.  A virus maybe, or even a Microsoft update.

 

A file can become Read Only via an Attrib setting in Windows Properties, a DOS command, or a Windows 7 Sharing function.  Not being able to format the drive brings it to a different level.  Maybe a Windows function like a Recycle bin or System Restore folder is in use by the system or a bug in a anti-malware app has it open.  If the problem carries over to a different OS then it gets more convoluted.  Maybe the FAT got screwed up.  But the error falls back onto the OS that caused it.

Re: SanDisk Cruzer Blade 16GB write protected error

Looks like there are a quite number of issues about the Write Protected Error. Is this considered to be an ongoing issue? 

 

I hope not.

Gee, according to your other posting it's being worked on and a solution is coming soon.

Re: SanDisk Cruzer Blade 16GB write protected error

Same issue here - brand new SanDisk 32GB USB stick, now being reported by

both windows and two linux systems as being write protected.

 

Tried using the low-level partition tool fdisk on both linux systems to wipe the partition table,

and even that low-level tool was telling me that the partition table on the stick

is non-writable/non-updateable.

 

Sorry, but at this level it's not your choice of OS or any of its particular foibles - it's

the chipset in the USB stick..

 

So now I have a USB stick that I want to return  for a refund/replacement, but

unfortunately it has a lot of files already on it from my fathers PC, some of which

contain sensitive personal data.  So I've got NO WAY to securely erase this friggin

thing before I send it back for refund(where it will pass through -how many- hands)?

 

I'd take a hammer to it, but then I won't get a refund.  I'm between a rock and a hard

place, thanks to SanDisk.

 

 

I'll be extremely angry if this was a known hardware flaw, and SanDisk failed to

do a proper recall after they'd found out.  How many lots of these defective

beasts have they continued to sell?

 

I think it's time for a class-action suit.

Re: SanDisk Cruzer Blade 16GB write protected error

What a joke.

 

Halfway through a copy the 8GB Cruzer gave me the 'write protected' error.

 

Lots of posts about this. Was supposed to have 6GB of data on its way to the US (lots of files under a gig each so its not the 4GB limit problem) ... there is no way to circumvent this problem ... I've wasted money and hours and hours on this thing ... now I have private data on a Cruzer that I can't delete ... and I want my money back and compensation for my time.

 

I have tried everything even the DiskPart command line functions ... using DiskPart I switched to Volume 11 which was the Cruzer (I have a lot of drives connected to my machine) ... even DiskPart came back with a 'This disk is write protected' message!

 

Purchased a Lexar 8GB flash drive ... copied the files in no time at all ... no errors. DO NOT BUY SANDISK.

Re: SanDisk Cruzer Blade 16GB write protected error

this is a serious issue. This is not the first sanDisk product that has turned to ****. You guys must provide a solution rather than blaming windows

Re: SanDisk Cruzer Blade 16GB write protected error

It is definitely a hardware glitch. tried everythng in the forum and still no use. SanDisk should own up to their fault rather than make excuses. Stop wasting our time, by blaming the OS.

Re: SanDisk Cruzer Blade 16GB write protected error

I understand your frustration.

 

It has been my experience where I had a SanDisk USB stick that worked fine in one Win 7 pc be classified as unwritable in another Win 7 pc.  Putting it back in the 1st pc and it was writable just like before.  I got it to work in the 2nd pc my changing the Win 7 Sharing options for it to Read/Write and adding the Everyone user id to it.  SOME write protect / Read Only problems are Windows 7 related.  But I agree, not all of them seem to be.
