[CRASH+DISPLAY] Analysing an empty drive

I tried to scan une of my SD/MMC/CF or whatever card drive, empty, and the program crashed.

Here is the error log :

Recuva v43===========System Info: MS Windows XP SP2, Intel Pentium 4 CPU 2.93GHz, 2.0GB RAM, NVIDIA GeForce 7900 GT/GTOH?[19:54:27] ErrorNo: 536870913 OtherInfo:cundeletedrv_gtdisksz:ERROR_FREESPACE, syslaserr21, 21

By the way, again another display error conserning different drives. Only a screenshot can describe the problem :
