The ones I have are the slider in/out with a spring function; USB3 32G

Slide the plug all the way out and if it can be pushed back in but
resists by spring action - that is the one to avoid!

When I try to push the USB stick into a port the USB Stick spring
action keeps me from pushing the USB Stick in all the way!

So now you feel the need to send an off-topic crossposting to badmouth
SanDisk? There are newsgroups about hardware, you know.

I have several SanDisk flash drives:

- SanDisk Cruzer Micro 512MB
- SanDisk Titanium 4GB
- SanDisk Cruzer Contour 16GB
- SanDisk Cruzer Extreme Pro 128GB

None of them give me trouble.

When I think it is in I try to get data on or off the stick and it
fails half way through the transfer. Sometime screwing up the USB
Stick making it unusable for Wn XP. I have to plug the USB Stick into
a Win 7 PC and do a disk check to get the functionality back.

AFAIK SanDisk offers warranty:
