Archos 40 Titanium : could it crash my microSD cards ?

[Consommateur5829]

I own the smartphone Archos 40 Titanium since 2 weeks. I used it without microSD for one week without issue.

Now I have put microSD cards into, and I get very strange behaviors (phone crash, can file folders but nor files, can not open MP3 nor JPG files, Android say microSD are corrrupted and ask if I want to format it while they still work fine onto a computer).

Is it possible that this phone corrupt my microSD cards ? is it a known issue with this phone or ever happen with other devices ?

My microSD cards (FAT32) :
- SanDisk microSDHC 16 GB (class10)
- PNY microSD 8 GB (class4)

I have tested with my old microSD card, and asked Sandisk, the origin is my Sandisk microSD card that is faulty.
