I believe that there is a known issue w/ Sandisk and the Toshibas. If you want to save yourself the possible headache, go with a different brand. If you want to take your chances and save some money, try the Sandisk. Why do you think it's so much cheaper than the others? :? I asked the same thing before I bought mine. I bought it locally, JUST IN CASE, so that I could return it, but thankfully, mine works well thus far.

It's been about 4-5 months.
Someone else mentioned that it appears to be a bad batch in the CA area? Hope it's resolved for you.
