Re: SanDisk Cruzer Blade 16GB write protected error

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. Smiley LOL

Re: SanDisk Cruzer Blade 16GB write protected error

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.

Re: SanDisk Cruzer Blade 16GB write protected error

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 Happy

 

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.

[ Edited ]

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.
