[gentoo-user] After sdcard failure / filesystem corruption...out pf pure curiosity...

Hi,

ok, seems that at least the data of one of the three partitions
of my sdcard is toasted...

But it would be interesting to check, what the initial (?) reason
for that failure is: Hardware or logic -- sdcard or filesystem.

Is there any flash-memory-friendly and -aware checker out there,
which detects sectors which cannot be recovered back to functioning?

Thank a lot for any help in advance!
Cheers
