Disk too small

#1 Post by minieagle » 02 May 2013, 09:31

Hi !
I am new to this forum (and testdisk as a tool) and I have an USB disk where I´m trying to receover the partition. Please let me have your suggestions. I receive the message "The harddisk (500 GB/465 GiB) seems too small!" (<2450GB / 2283 GiB).
The following partitions can't be recovered

Partition Start End Size in sectors
> FAT32 50099 82 49 297953 84 37 3981774625
FAT16 LBA 70520 22 8 191104 193 62 1937192788

Here is the log file:
