My USB drive is suddenly Read-Only

Wasn't entirely sure where to post this, but here goes.

I've been using a Sandisk Cruzer 32 BG USB Stick for a few months now with now problems whatsoever. I turn my Mac on this morning, and suddenly, for no reason at all, the USB stick is in Read-Only mode with no option to change it. I press cmd +i to get info, I can't change the permissions to write and read, there's no lock symbol, it just says "You Can Only Read".

Before any of you ask, the USB drive does not have a little physical switch on it, to change from read only to write.

Next, I go to Disk Utility, and try to verify and repair the disk. Sounds Simple. Under First Aid, 'Verify Disk' is the only option that isn't grayed out. I can't repair anything. And when I click Verify, I get the Error:

First Aid failed

Disk Utililty stopped verifying "NEAL STUFF" because the following error was encountered:

The underlying task reported failure on exit.

And in the Log, I see:

***** FILE SYSTEM IS LEFT MARKED AS DIRTY *****

Error: The underlying task reported failure on exit

1 non HFS volume checked

Volume needs repair

I successfully was at least able to backup my files on my harddrive. So, I figured I might be able to reformat it. But then, all of the options for erasing it are grayed out as well. It's been formatted as fat32 since I got it, so I wouldn't really want to format it differently, as I do have to get on windows occasionally.

So, I'm reading up on "solutions" and tutorials all over the net, and can't find a single one that works. 95% of all of them are tailored to windows. I have a windows laptop, and tried some of them on there as well, much to my impatience for the inferior system. Of course, all of the tips involve all sorts of regular windows cryptic BS and whatnot.

I'm starting to think that it's just a crappy stick, but I still want to refuse to believe it, seeing as I've only had it for a couple of months and worked perfectly until now. I know they're pretty cheap, but it's the precedence of not wanting to be ripped off.

I'm not extremely computer-savvy, so I'd rather not mess around in terminal, but I will if it gets the job done. So, I haven't been able to find one definitive solution to the problem, so any help would be greatly appreciated.

If any of you can't figure it out, or that you find that's it's unfixable, I'd at least like to know what could've caused it, if anything besides crappy construction.
