I use SanDisk MicroSD cards daily in development and testing of DietPi: http://fuzon.co.uk/phpbb/viewtopic.php?f=8&t=6#p6
I have a MicroSD card from SanDisk and its now failed after 2 months of usage. So i did the usual thing and sent a RMA request thinking this would all get resolved.
Here is the reply I received from SanDisk:
Image of the email i received: http://fuzon.co.uk/downloads/Sandisk.pngWe received your product replacement request however retail memory cards are not designed to be used as bootable device and may reduce the life expectancy of the card due to the high number of reads and writes.
We do not support this use and for that reason the replacement will not take place.
Has anyone ever experienced this with SanDisk in the past?
Are their any SD card manufactures that will commit to RMA for bootable devices. I'am completely annoyed at SanDisk and confused as they always seemed to be the most reliable.
