Issues reformating a read-only flashdrive

Question

Here's the link to my previous question regarding the flashdrive: http://discussions.apple.com/thread.jspa?threadID=2255840&tstart=0
It was suggested that I reformat it but I'm having issues. I tried following instructions off another website but that got me nowhere. Could someone give me the idiot proof instructions?

Answer 1

When mine became partially defective, long out of warranty, there was
no trouble using Disk Utility in the Mac OS X to erase & reformat it.
The cost of these has come down somewhat, even in my state where
most everything is marked up well beyond the real costs involved. I
can get good name brands with a warranty from warehouse or big-box
stores when I am in the largest town in my state, from national resellers.
So, I look at the Flash USB drives as a disposable commodity, when
compared to a CF camera card for my Nikon DSLR, of equal capacity.
And this comparison also adds the read-write speeds of the camera.
+A new 64GB Flash USB drive is under $150. now, since more products+
+are using flash memory and the market has driven some prices lower.+
+The 16GB Flash is about $30. or so, even among good brands.+
But if it does not work, there still may be a warranty or guaranty.
Some have a two-year limited warranty, so it is worth a look.
In any event, if disk tools and formatting can't help, it does not matter
what the item cost; the value becomes zero.
Good luck & happy computing!
