I join the long list of customers who have had their SanDisk die on them.  Customer service from SanDisk has been helpful.  They pay for UPS shipping for the return and promise a 7-10 day turn around once the defective disk has been returned.  Still it's a pain to deal with and I lost some photographs.UPDATE: SanDisk sent me a replacement and it seems to be working.  If the replacement goes bad, I'll be back to complain:)SECOND UPDATE: All is well with the replacement so I'm giving it three stars.
