The SDOCK2U33RE Dual 2.5/3.5" SATA HDD/SSD duplicator dock lets you duplicate/clone an existing hard drive without the use of a host computer system -- or dock and swap drives from your desktop or laptop computer simultaneously, using a single USB or eSATA port.

Versatile Features

The SDOCK2U33RE offers convenient dual-function performance. As a hard drive duplicator, the SDOCK2U33RE lets you create an exact sector-by-sector clone from one hard drive to another, including partitions and boot sector information -- ensuring data integrity and consistency for sensitive operations, such as data recovery. As an external hard drive dock the SDOCK2U33RE lets you connect your drives through either eSATA or USB, with each drive slot individually supporting high capacity 2.5/3.5" hard drives or solid state drives, tested up to 4 TB.

Fast Performance

With support for SATA III (6 Gbps) you can maximize efficiency with duplication speeds up to 22 GB per minute, and eSATA docking speeds up to 6 Gbps. The Dock can also be connected through USB 3.0 with UASP for transfer speeds up 5 Gbps (70% faster than conventional USB 3.0). See our UASP testing results below for further details.

Hassle-free Operation

With push button operation and plug-and play installation, the duplicator dock has been specially designed for hassle-free operation.  The SDOCK2U33RE lets you quickly dock your hard drives or start duplicating hard drives with the push of a button. Plus, the built-in LED progress bar saves you time by letting you easily monitor the entire duplication process, so you'll  know exactly when it's time to start your next operation.

For added compatibility with different drive types in duplication and docking applications, the SDOCK2U33RE supports the use of various drive adapters. The below list of StarTech.com adapters have been specifically tested, to ensure compatibility with this drive duplicator:

Frequently Asked Questions

Troubleshooting

Ensure there is no USB cable connecting the duplicator to a computer.

  1. The drive may be damaged. Test with a known-working drive, or test the drive directly to a PC.
  2. The operating system on the computer may not support reading and writing to the file system on the docked hard drive or SSD.  Remember, Windows cannot read Mac or Linux file systems. Also, macOS can read but not write to NTFS drives.
  3. If the drives came from a RAID (Redundant Array of Independent Disks), they would not be accessible in our docking stations.
  4. If the drive uses 4Kn sectors, check the technical specifications of the docking station, and ensure it can read 4Kn drives.

SATA hard drive controllers require a feature called port multiplier to read more than one hard drive per SATA or eSATA port. The port multiplier feature is not standard on many SATA hard drive controllers.

If your computer is only recognizing one of your hard drives, you need to plug the eSATA cable into a SATA controller that includes the port multiplier feature. If none of your current hard drive controllers include this feature, you can add a hard drive controller that does support port multiplier in any available expansion slot (for example, PCI, PCI-Express, PCMCIA, CardBus, or ExpressCard). StarTech.com has hard drive controllers available that support the port multiplier feature. To view the hard drive controllers, click here: http://startech.com/Cards-Adapters/HDD-Controllers/SATA-Cards/?filter_PORTMULTIPLIER=Yes.

If you have a hard drive controller card that does support the port multiplier feature but it is only reading one hard drive at a time, update the drivers of the hard drive controller. To find the most current StarTech.com drivers, click here: http://www.startech.com/Support.

When you troubleshoot issues with a hard drive dock or duplicator, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:

  • IDE, SATA, and eSATA cables
  • Hard drives
  • Hard drive dock or duplicator

To test your setup components, try the following:

  • Use the cables, hard drives, and hard drive dock or duplicator in another setup to see if the problem is with the components or the setup.
  • Use a different cable, hard drive, and hard drive dock or duplicator in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.

When you test the hard drive and hard drive dock or duplicator, it is recommended that you do the following:

Note: For a hard drive duplicator you may need to switch the device to PC mode (if available).

  1. To check Disk Management, press the Windows key + R, type diskmgmt.msc, and press Enter. Check to see if your hard drive is listed.
  2. Do one of the following:
  • If the hard drive is listed with unallocated space, the hard drive needs to be reformatted. Right-click unallocated and click New Simple Volume. Follow the on-screen instructions to complete the reformatting.​

Note: Formatting a hard drive erases all of the data on it. Make sure that you back up all of your data before you reformat the hard drive. 

  • If the hard drive is listed as healthy but does not have a drive letter, for example, C:, right-click healthy and click Change Drive Letter and Paths. Click Add, assign a drive letter, and click OK.

Note: A formatted hard drive will not show up in Computer or My Computer until it has a drive letter assigned to it.

This docking station allows the hard drive to enforce its own power state, as opposed to enforcing a power state that keeps the hard drive active at all times. Since most newer hard drives have low-power energy conservation modes, this will cause the hard drive to enter an idle state if it is not used for a certain amount of time. 

 

You do not need to format your target hard drive before you begin to duplicate it, because the target hard drive is automatically overwritten during the duplication process.

The hard drive duplicator copies the exact partition from the source drive to the target drive. Since it is required that you use a target drive that is equal or larger in size than the source drive a portion of the target drive appears as free space. You can append free space to the live partition on the target drive so that the full size of the drive can be utilized.

Note: A partition cannot be extended on an operating system drive that is in use. You must extend the partition when it not being used by the operating system, and ideally when it is still connected to the duplicator.

Extend a partition on a computer running Windows

Note: Do not extend a System Reserved partition. Only extend the primary partition, which is typically the largest in size and formatted with NTFS or FAT32.

After you have successfully duplicated a drive and the target drive is still connected to your computer system (for example, through the duplicator), complete the following:

  1. Press the Windows key + R.
  2. Type compmgmt.msc and click Ok.
  3. In Computer Management, on the left side of the screen, click Disk Management.
  4. Find the target drive. It will most likely be at the bottom of the list, have a partition that is the same size as the source drive, and have an unallocated area on the drive.
  5. On the target drive, right-click the last partition on the right side of the screen and click Extend Volume.
  6. In the Extend Volume wizard, click Next. By default, the remaining drive area is the amount of space used.
  7. Click Next > Finish.

The primary partition on the drive now uses the entire drive area.

StarTech.com hard drive duplicators only read from the source drive and only write to the target drives while in standalone duplication mode .  A duplication that fails or halts will not cause a problem with the source drive.

You can use this device to duplicate an internal hard drive with the stand alone duplicator function if you remove the hard drive from the computer and connect it directly to this device.

How To

It is not possible to duplicate from a larger drive to a smaller one.  The capacity of the target drive must be equal to or greater than that of the source drive.

To confirm that the Mac OS detects your USB device, complete the following:

  1. Click the Apple icon.
  2. Click About This Mac.
  3. Click More Info or System Report.
  4. Under the appropriate heading, confirm that your USB device is listed and that there isn't an error. For example, a network card would be under Ethernet Cards.

You may need to refresh the System Information page after you plug in your device.  To do so, press Command R with the System Information page open.

Your USB device is listed according to the name of the chipset. To determine the name of the chipset of your USB device, navigate to www.StarTech.com and look on the Technical Specifications tab for your product.

Before You Buy

Some old hard drives (often low capacity as well) may not work because they use an old IDE standard not supported by the duplicator.  Use a newer drive to determine if the duplicator works or if the drive is not compatible.

StarTech.com hard drive and flash drive duplicators perform a sector by sector copy, which means that the target drive must be the exact same size (down to the sector) or larger than the hard drive or flash drive that is being copied. During a sector by sector copy, each individual sector is copied over to the target drive, regardless of whether or not any data is present. A 500 GB hard drive with 50 GB of data on it will take the same amount of time to copy as a 500 GB hard drive with 450 GB of data on it.

If you have two hard drives or flash drives that are listed as the same size but are different makes or models, you need to check how large both drives are down to the sector to ensure that the target drive is the exact same size or larger.

Solid-state drives (SSDs) use SATA connectors to access power and transfer data. Any duplicator that can copy to or from SATA hard drives will work with a StarTech.com duplicator.

Note: If you use a dock to duplicate SSDs, keep in mind that the StarTech.com disk duplicators execute a sector by sector read and write. SSDs are rated by a number of reads and writes. Repeated duplication and sector by sector reads and writes of SSDs can reduce the life cycle of the drive.

Software-level encryption on the drive poses no issue to StarTech.com duplicators, as the duplicators copy encrypted data sector by sector over to the new drive.

Hardware-level encryption or BIOS level hard drive locks cause the duplication to halt and fail, as the drive is unable to read or write the sectors that are encrypted.

Duplication of Hidden Protected Area (HPA) Partitions or Extended Industry Standard Architecture (EISA) cause the duplicator to halt and fail, as the drive cannot read and write the protected partitions on the drive.

Note: Our UNIDUPDOCK, SATDOCK22RE and SATDOCK4U3RE do include the ability to copy HPA partitions, but the duplication is still dependent on how the HPA partition is written to the hard drive, whether or not it is encrypted and how it is encrypted.

StarTech.com duplicators were not designed to recover failing or damaged drives. If the duplicator encounters a corrupt or unreadable sector, the duplication halts and fails.  If the source drive has bad sectors, use the Read Error Skip feature if your model of duplicator has it; however, if there are too many errors, it may still halt and fail even with this feature. If this happens, you will need third-party recovery software or custom-built recovery hardware to copy from a failing or damaged drive.

To determine if your hard drive will work in this device, on the product page, click the Technical Specifications tab, and do the following:

  • Make sure that the device supports the storage size of your hard drive. If the storage size of your hard drive is larger than what the device was tested with, the hard drive will likely still work with the enclosure.
  • Confirm that your hard drive uses the same interface type as the device. For example, IDE, SATA, or M.2.
  • Make sure that the device supports the physical size of your hard drive, such as 2.5 inches or 3.5 inches.
  • Verify that the power consumption of your hard drive doesn’t exceed the power output of the device. If you’re using multiple hard drives, make sure that the combined power consumption of all of the hard drives doesn’t exceed the power output of the docking station.

Hard Drives

Windows 10 

Before you can access a new or formatted drive in your operating system, you need to initialize it first and then create a partition on the drive. A partition defines an area of the drive to use for storing data. The partition uses a file system (for example, ex-FAT, NTFS, and so on).

Initialize a drive

Note: You typically only need to initialize a drive if the drive is new. If you cannot find an uninitialized drive in Disk Management, skip the following steps and try to partition your device.

  1. Press the Windows key + R, type compmgmt.msc, and click Run to open Computer Management.

  2. Navigate to Disk Management.

  3. When prompted to, initialize your disk(s). If you are running Windows® 7 or later and are using a drive larger than 2TB, initialize the disk(s) with GPT. If you are running an earlier version of Windows, initialize the disk(s) with MBR. For more information, visit the following FAQ: https://www.startech.com/support/faqs/technical-support?topic=hard-drives#mbr-vs-gpt.

  4. Click OK.

Create a partition in a drive

Note: The following steps create an NTFS partition that uses the entire drive space. To use a different file system, select a different option in step 6.

  1. Right-click Unallocated or RAW volume, and select New Simple Volume.

  2. In the New Partition Wizard, click Next.

  3. Select Primary partition.

  4. Leave the partition size set to default, and click Next.

  5. Assign a drive letter or leave it set to the default, and click Next.

  6. Enter the following settings to format the partition:

  • In the File System field, enter NTFS.
  • Set the Allocation unit size to Default.
  • In the Volume label field, enter <your name/reference>.
  • Select the Perform a quick format check box.
  • Clear the Enable file and folder compression check box.
  1. Click Next > Finish.

The new drive should appear in Windows Explorer.

Mac OS

Before you can access a new or formatted drive in your operating system, you need to initialize it first and then create a partition on the drive. A partition defines an area of the drive to use for storing data. The partition uses a file system (for example, HFS+, ex-FAT, NTFS, and so on).

Initialize a drive

Mac OSX detects a drive that needs to be initialized and automatically prompts you to initialize the drive. If you are prompted to initialize the drive, click Initialize. If you are not prompted to initialize the drive and you cannot find the drive in Finder, you will need to create a partition on the drive.

Create a partition on a drive

Note: The following steps create an HFS+ (Mac OS Extended (Journaled)) partition that uses the entire drive space.

To create a partition on a new drive, complete the following:

  1. Open Finder.

  2. Navigate to Applications and click Utilities.

  3. Open Disk Utility.

  4. Select the new drive and click the Partition tab.

  5. Click Options and verify that it is set to GUID Partition Table.

  6. Enter a name for the partition.

  7. Click Partition.

The drive should now be accessible in Finder.
