Re: [MiNT] mv does delete when fail of fat (was: 1-18-cur trunk stability issues)



We do need a more comprehensive undelete tool for Mint that
can handle FAT32 and longfilenames properly.

I did mention a couple of candidates on this list a few years
ago and managed to build Photorec but it doesn't recognise the
mint file systems.

Regards,

Peter
