Q1: What are the key functions?
The Ninja is compatible with any ATA or SATA hard drive. Main functions include "Duplication (Mirror Copy, Bad-Sector Skip Copy, Data-Only Copy) and Security Wipe (DoD, NSA. Raw Level Format). Additionally, it provides a cross-copy function between ATA and SATA as well as a clipping function (capacity clip for target drive).
Q2: What is mirror copy technology?
Mirror copy is a function where all sectors in a hard drive are copied to a target drive. It does not look at drive structures and can therefore copy any type of known or unknown data and OS system. The finished product is two identical hard drives.
Q3: What is a “Backup copy”?
Backup copy is a copy function that skips bad HDD sectors and copies all good data from the master HDD. Other copy functions, such as "mirror copy," abort the copy process when a bad sector is encountered.

Note: Bit compare function will not be performed for this mode.
Q4: What is the” Smart Copy”?
YEC Smart Copy is a data-only copy method that works for every OS. Other data-only copy methods read the HDD file allocation table in order to map a drive, and are therefore limited to Windows OS. YEC Smart Copy analyzes the hard drive on a sector-to-sector basis, so it has no limitations (Unix, Linux, data-encrypted drives..etc)
Q5: What is the” FS Mapping Mirror copy”?
The FS Mapping Mirror copy function analyzes drive structures and only copies sectors that are occupied by useful files and data. This technology applies to all master drives containing FAT16/FAT32/NTFS type partitions (MS-DOS or Windows).
Q6: What is the” FS Mapping Flexible copy”?
The FS Mapping Flexible copy function analyzes drive structures and only copies sectors that are occupied by useful files and data. It is able to adjust to various drive structures and sizes. This technology applies to all master drives that contain FAT16/FAT32 type partitions.
Q7: What is the Cross Copy function? (*Not included for Ninja )
The Cross Copy function performs duplication between ATA and SATA hard drives. It is commonly used in producing temporary backup drives. Cross Copy utilizes the mirroring function so that all sectors in a given drive are cloned from beginning to end.
Q8: How do I operate the Ninja?
  • Turn on Ninja.
  • Connect Master and Target HDD to corresponding HDD ports.
  • Select corresponding interface for each drive (ATA/SATA).
  • Select desired function and press [START] to initiate.
  • Once completed; Buzzer, LCD and LED will signal the end of the operation.
  • Green LED signifies successful completion, red LED signifies abort or problem found.

Q9: Does the Ninja work operation systems such as UNIX, and HPFS?
Yes, but not for FS mapping mirror copy and FS mapping flexible copy functions. Otherwise operation systems (OS) will work for all ATA and SATA applications. (*Ninja is only for ATA)
Q10: Does the Ninja  work with any ATA and SATA interface Hard Drive? (*Not for Ninja )
Yes, for ATA drives, it supports LBA & CHS addressing as well as PIO and UDMA interface modes. All interface mores are supported for SATA drives. Optional adapters are required for 0.85", 1", 1.8" ATA Hard Drives and 8 bit narrow and SCA SATA Hard Drives.
Q11: What options are available?
There are 1.8, 2.5 and 3.5 inch Hard Drive conversion adapters available. Auto-loaders are available for certain applications. The standard Ninja software host program includes a Terminal setting for script command input for in-depth customization. Please ask a YEC representative for script customization options or availability of other options.
Q12: What does "00:UNCORRECTABLE ERR" mean?
"00: UNCORRECTABLE ERR" means that you have a bad master HDD, meaning that it is bootable but the HDD has bad sectors in some area(s) of the disk. Solution: Test the HDD using Ninja .
  • Set the HDD to Target
  • Perform [3:Once Cycle Test] in normal item mode.
  • Check the results of this test. Device should show error message: UNCORRECTABLE ERR with specific sector #.
    To counter this type of problem and still perform the copy function:
    • Prepare known GOOD HDD.
    • Set the bad HDD to Master and set known good HDD to Target.
  • Perform [5:BACKUP] to copy only good sectors.
  • Set the known good HDD (containing data) to Master and set the new HDD to Target.
  • Perform [8:FS FLEX or FS MIR].

Q13: What is the difference between the Ninja and the Ninja-F?
The Ninja-F has all of the same functions as the regular Ninja duplicator with additions for use in forensic computer investigation. These additions are:
