When adjusting settings, keep in mind that:

  • changes to recovery parameters do not apply to recoveries already in progress;
  • changes to display and visual parameters do not apply to currently open pages.

FAT16/32 filesystem settings

Short file name encoding

FAT filesystem uses Unicode for long file names, but DOS OEM encoding for short file names. You only need to adjust this setting if the locale of the PC on which you perform the recovery does not match the locale of the original filesystem and short file names in the national language come out garbled. In practice, this situation is rare because, in most cases, the driver writes Unicode long file names anyway.

NTFS filesystem settings

Filesystem parameter detection

This option controls how Klennet Recovery determines the filesystem parameters, notably the cluster size. NTFS keeps these parameters in the boot sector. If the boot sector is damaged, the recovery algorithm determines the correct parameters based on the data on the volume.

However, the task becomes complicated when the volume stores virtual machine disk images (like VHDX images) also formatted as NTFS. In this case, the volume holds several incompatible sets of metadata, one for the volume itself (the "outer" set) and one for each disk image stored on the volume (the "inner" one). The algorithm often gets confused because it cannot differentiate between the "inner" and the "outer" parameter sets.

On the other hand, even if the volume is formatted, the format procedure selects the same parameters because the parameter set is chosen based on the volume size.

In summary, the recommendation is to select Use boot sector if available unless you know the volume was re-formatted with a non-default cluster size.
