When detecting stripe size and member disk ordering, use...
ZAR data recovery software uses two kinds of patterns to detect RAID parameters -
"doublets" and "triplets". "Doublets" are shorter and encountered more often.
However, they are less reliable than longer, rarely encountered "triplets".
"Doublets" tend to produce more false positives for the algorithm to cope with.
Per gigabyte of typical volume, 10 to 20 "triplets" are typically found, which
is quite enough to determine the array layout. The same amount of data probably
contains about a hundred of "doublets", half of which are misleading. Larger the
array, less the need for (and value of) "doublets".
Default setting ("triplets") should be used for any array containing more
than five gigabytes worth of data.
Use NTFS MFT entries, if any.
With this option enabled, ZAR will take into account any MFT
entries found on the volume. Leave it enabled as per default settings, unless
the RAID reconstruction is very slow (possible with an extremely large array,
containing more than a million of files and/or directories).
This should be enabled unless the array reconstruction fails and any of
the following conditions is met
The filesystem on the array is NTFS formatted to FAT or vice
versa (i.e. fragments for both filesystem types are on the array).
The filesystem on the array is NTFS version 1.2 (volume
formatted by Windows NT 4.0).
