Subject: Tech: Removing write-protection on USB drive
From: Bonnie Shaljean
Date: 31 Jul 14 - 08:48 AM

I've been saving back-up copies of my files on a Kingston 32g USB stick, and have used this particular one quite happily for about six months or so (less than a year anyway). But for some reason it has now decided to write-protect itself and won't let me add or change any of the documents on there, though I can still access them. It says now that they're read-only. I never did anything to it, it just decided to start behaving this way.

I normally use this drive on my Mac (10.6.8), but Disk Utilities can't repair or even verify it. I then tried it in my PC (Windows 7), which reads it OK, but I get the same freeze-out. The PC says to remove the write-protection, but I'm damned if I can figure out how. I can't find any option to untick, and clicked everything I can think of to click, on both computers. I'm out of ideas.

I really want to sort this because it's going to be a huge hassle setting up a new back-up drive (I have a lot of folders-within-folders shortcuts set up in my filing system, plus other joys... don't even ask...)

Any help out there? Thanks!

Use another USB.

This one is sending you a very clear warning. Back up your backup.

I was told a number of years ago NOT to make permanent backups on USBs - they are unstable.

CDs or DVDs are much more stable and trustworthy. Yes I know they are a pain to set up and take more space but surely worth the effort.

Alternatively use remote Hard Discs - these are more affordable these days and can be accessed more easily than CDs or DVDs. The only question is how stable they are?

Personally I back up all my original live sound recordings, photographs and live movies on DVDs and Remote HDs I also back up photographs on CDs. That is as well as the basic copies I download from the respective sound recorder, cameras or camcorder to my main PC.

Edited stuff I back up only to Remote HDs.

It can be tedious at times but so far - touch wood - I have lost nothing.

Thats interesting Bonnie, I've had the same thing happen to me with some USB's used with Mac. Even stranger I can read/write to it on a PC but then again not on the Mac.

Right clicking on your drive should give you the Get Info screen and show you the applicable permissions to your USB stick. You should see your username and Read & Write next to it. If something has changed, lord knows why, you might be able to reset your access by clicking the little padlock at the bottom of the window.

Re the other comments about reliability of USB drives, I agree. I have a hard drive or CD back up and then basically use the USB to carry things around on without having to sweat on losing the stick and something rrrrreally important…. but I guess you'd probably be aware of all that anyway so no need to labour the point :-)

Cheers,

Andrez

This was an answer from the link in your first reply

"Saga Lout said:
The files could have been marked as Read only somehow. Check the Properties of one of the files and see what show up at the bottom of the Properties page.

If it shows Read Only, change the attribute of all the files on the stick using the Command Prompt and by typing:-
attrib -r x:\*.*
then press Enter. The x above has to be replaced by the actual driver letter of the stick at that time.


You are a genius man:) Thanx for the Trick:) "


Might be worth a try.

CDs and DVDs are not as reliable for long term storage as one might think. They consist of plastic bonded around a thin layer of metal into which billions of tiny holes are burned. The differing materials may delaminate over time or due to temperature humidity variation. Check on the internet to make sure you've got a reliable brand and it is stored appropriately.
I find that magnetic storage is reliable over long term provided I find a safe place for them in external hard drives.
Then you need to be sure that methods exist for getting data off these storage media at some interval in the future. It's getting harder and harder to find LP players, cassette players, slide projectors, and ditial tape players.
Think things through.
