This is a strange one..
Four different memory sticks this has happened to, I bought 3 x Verbatim Pinstripe 8Gb Sticks and one Sandisk Cruzer Blade 8Gb for use in VU+ Duo and a Skybox F5s.
All now appear to be ok but when inserted into either box, for example to reflash latest openvix image (090) - not seen, cannot load the loader or the image, same thing on all four sticks!
They have been unwrapped, inserted into PC to copy the necessary files to and then put in the VU+ Duo...
Is it possible the PC is damaging them in some way ?
Have just re-inserted to PC and copied some files to them and then back from the stick to a different location, no problems.
They are formatted to FAT32 out of the box, have also reformatted to FAT32 and still get same issues.
Any ideas ?
It's baffling me !
