USB Stick Suddenly Write Protected?

USB Stick Suddenly Write Protected?

I have had a Maxell 15 GB, FAT32 usb stick for a few years with several operating systems and it was working fine until recently.

It does NOT have a write-protection switch.

I have Windows 7 Home Premium 64 bit. I used it on a Windows 7 Professional machine and saved several files to it with no problem.

But then I started getting error messages about files not being writeable.

So I made sure the folder they were in and all it's contents were all set to not read only and tried again.

Then I started getting errors that the disk was write-protected and to remove write protection. It does not HAVE write-protection.

I could only save a small proportion of the files I needed.

Then I used it on the Windows 7 Home premium machine and it was still write-protected. I cannot copy anything to it and I can not delete anything from it.

Luckily, I COULD copy the data from it to my desktop.

But the thing is now unusable.

I tried Google and there are zillions of hits for this with Windows 7. Why on Earth would Windows 7 do this and make a usb stick useless?

Any suggestions?

    The most common fault symptom for a USB stick is that it becomes read-only.  It's a characteristic of USB stick technology that it has a limited life [but predictions vary wildly from 100,000 full write cycles to a million].

    It's not Windows 7, it's just usage.

    Try rebooting the computer into safe mode with command prompt. Insert the drive and check the drive letter assigned. Then format the drive.

    They have a very specific life limit so as the drive is a "few years" old the drive may be unusable.

    Yes, I tried that earlier and it got to 100% and said it had a trillion zillion bad sectors and no sector zero or something.

    So is it truly stuffed now?

    But if it is a dud, how could I get the data off it?

    This is not a OS problem. Most likely your USB stick has reach its lifespan. Other things you could try to troubleshoot your USB stick are by running a scan disk to search for a possible corrupted FAT table, trying the USB stick in different Windows PCs or a trying it in Unix/Linux PCs.
