them as appropriate.
18 Steps from
UDMA-6 133MB/s
(default) to
PIO-0 3MB/s
AUTO SKIP Automatically skips bad sectors where an error
occurred.
[Configuration Tips]
This setting is useful for recovering data on good
sectors from a damaged hard drive. However, it does
not guarantee the integrity of the extracted data,
because all the unreadable sectors are skipped.
ON: enabled
OFF: disabled
(default)
RETRY COUNT Specifies the number of retries when an error occurs.
* The operation automatically stops if a sector cannot
be accessed after the specified number of retries.
[Configuration Tips]
Setting RETRY COUNT at 0 in combination with
AUTO SKIP is effective for extracting data on good
sectors from a damaged hard drive.
1-99 (5 at default)
TIMEOUT RETRY Retries accessing the hard drive on device response
timeouts.[Configuration Tips] Setting allows retries
when no response from the hard drive. It is
recommended that you stop the operation when the

6. Troubleshooting
If the KD25/35PRO fails to function as expected, check the list of common problems below:
•The KD25/35PRO not recognized by the host PC
oConfirm that both the USB cable and the AC cable are connected.
oConfirm that the power LED light is on.
oConfirm that HDD is set to Master (or SingleDrive).
•Cannot start up the OS from the KD25/35PRO.
oStarting up an OS from the Main Unit through USB is not supported.
oFor eSATA, check you eSATA I/F configurations.
•Slow data transfer speed.
oUSB1.1 has a lower transfer rate—approximately 1MB/sec.
•“Formatting failed” dialog is displayed when formatting with Windows2000
oWindows2000 does not allow you to create a FAT32 partition larger than 32GB. Use NTFS or
format with other OS including Windows98SE/Me, in advance.
•Cannot copy or stops during copy process.
oYour hard drive may be damaged. Check your drive in the Standalone Mode first.
•Only one of the two connected hard drives is recognized in the Standalone Mode.
oFor Windows2000, confirm that ServicePack4 is installed.
oFor eSATA in the Standalone Mode, only DISK1 is recognized, but not DISK2.
Note for some Maxtor HDD, including Seagate HDD manufactured by Maxtor, it appears they are only
designed for use with mounting frames or cases, thus they show different data transfer speeds depending
on the angle and position of the connection when used without the proper mounting frame. *
*This problem is not limited to use with the KD25/35 PRO: it will when directly connecting to a computer
motherboard as well.
Possible Solutions:
•Connect HDD upside down
•Find a way to hold HDD away from the ground
•Put metal frames around HDD
*Hitachi and Seagate hard drives do not have this problem.

7. FAQ
Q: Can I copy a smaller drive to a larger drive, and vise versa?
A: Yes. If the target drive is larger than the master, you can copy entire data. If the target is smaller, the
operation stops when the target drive reaches its max capacity, allowing you to copy only part of the data
on the master drive.
Q: When the target drive is larger than the master, what happens to free space on the target drive after
duplication?
A: The KD25/35PRO copies partitions as well. If the master drive is 40GB and the target is 80GB, it copies
40GB of data, and the target drive will have 40 GB of free space remaining.
Windows2000/XP Free space usable by disk management.
Macintosh Free space not usable.
Q: Can I copy drives of different rotational speeds and transfer rates?
A: Yes, but you need to change the transfer rate configuration in OPTION for ATA hard drives not
compatible with UltraDMA. SATA hard drives do not need any additional configuration.
Q: Can I copy unsupported OS drives, including Linux?
A: Yes. The KD25/35PRO can perform a sector-to-sector copy, and does not differentiate file systems and
data formats on drives. If the copied hard drive is exactly identical to the source drive in size, brand, and
manufacturer, you can use it on the OS, but if the drives are different, use the copied drive at your own
risk.
Q: Can I use a hard drive for copy that has bad sectors?
A: The product is not a repair tool, and does not read bad sectors that are unreadable with PC. It can,
however, copy data on good sectors to another drive by skipping the bad sectors. Because it does not
recognize where the bad sectors are in the drive, we do not guarantee the integrity of the copied data.
Although it is technically possible to copy data to a hard drive with bad sectors that have writing issues
by skipping them, it is not recommended in terms of data protection.
Q: When I try to copy a 40GB drive of X brand to a 40 GB drive of Y brand, a warning message is
displayed.
A: Hard drives of different brands do not have exactly the same size even though they are both 40GB.
Hard drives with the same model number could also have slightly different capacities due to a lot size
difference.
Q: Are SCSI hard drives supported?
A: No. The KD25/35PRO only supports ATA and SATA hard drives. We are not responsible for the use of a
SCSI to IDE adapter (if there is any).

18
Q: Can I use an internal hard drive for copy?
A: You need to remove the drive from your PC first and then connect it directly to the KD25/35PRO in
order to be able to copy it.
Q: My source drive has very little used space. Can I copy it to a smaller target drive?
A: Yes, but you may not be able to copy all the data, because the operation stops after reaching the capacity
of the target drive.
Ex: Copying 20GB of data from a 40GB drive (20GB free space) to a 20GB drive:
-There is no information as to where in the master drive the data is written by the OS.
-The KD25/35PRO regards the blank sectors as sectors with null values (thus not empty).
For the reasons above, the integrity of the data is not guaranteed. To ensure complete duplication of the
data, use a drive of the same size or larger for your target.
Q: How long does it take for a copy to complete?
A: Copy time depends on the speed of the drives, but it usually takes about 1GB-4GB/min.
Q: Do I need to format the target drive before copy?
A: No. It will wipe the target drive, and write in the file system and format of the source drive to the
target.
