Frequently Asked Questions

Troubleshooting

When you troubleshoot issues with a hard drive enclosure, 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:

  • Cables
  • Hard drives
  • Hard drive enclosure

To test your setup components, try the following:

  • Use the cables, hard drives, and hard drive enclosure in another setup to see if the problem is with the components or the setup.
  • Use a different cable, hard drive, and hard drive enclosure 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 enclosure, it is recommended that you do the following:

  • To check Disk Management, press the Windows key + R, type diskmgmt.msc, and press Enter. Check to see if your hard drive is listed.
  • 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.

If your setup components support USB 3.1 but you are experiencing slower transfer speeds than you expected, consider the following:

  • A USB host connection with multiple USB 3.1 ports might not be able to support 10Gbps on each port simultaneously.
  • The type of port on a device does not determine whether the device is capable of USB 3.1 speeds. A USB-C port might not support USB 3.1 speeds, while USB-A and USB-B ports might support USB 3.1 speeds.
  • Any other devices that you include in your setup, such as an older hard drive in a USB 3.1 enclosure, might create a point of congestion and slow down transfer speeds.

To confirm the functionality of your USB host connection, its ports, and any other devices in your setup, refer to the information provided by the manufacturer.

Note: USB 3.1 is also known as USB 3.1 Gen 2 (10Gbps). Devices that support USB 3.1 should have the USB 3.1 symbol on them. If the USB 3.1 symbol does not appear on your USB source or device, refer to the information provided by the manufacturer to confirm whether the USB source or device support USB 3.1.

You should not upgrade your device's firmware if you do not have any issues with the functionality of your device. The only time you should consider an upgrade is if you are experiencing a problem with the device, and you have confirmed that the firmware addresses this problem.  You can confirm this is the case by reviewing the documentation included with the firmware or by consulting with our Technical Support team. Incorrectly upgrading firmware can result in diminished performance so it is best to contact StarTech.com if you would like to perform this operation.

Before You Buy

Yes, this device supports the TRIM command. If the OS issues a TRIM command, the command will be passed to the connected device.

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

  • Make sure that the enclosure supports the storage size of your hard drive. If the storage size of your hard drive is larger than what the enclosure 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 enclosure. For example, IDE, SATA, or M.2.
  • Make sure that the enclosure supports the physical size of your hard drive, such as 2.5 inches or 3.5 inches.
  • Make sure that the enclosure supports the height of your hard drive. For example, 9 mm or 15 mm.
  • Verify that the power consumption of your hard drive doesn’t exceed the power output of the enclosure. 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 enclosure.

USB 3.1 is the most recent version of the USB (Universal Serial Bus) standard for connecting computers and electronic devices. It is capable of data transfer speeds up to 10Gbps, and while it can use the USB-C connector type, it can also use a variety of other connector types. To achieve USB 3.1 transfer speeds, your USB host connection, cables, and device must all support USB 3.1. USB 3.1 is also known as USB 3.1 Gen 2 (10Gbps). 

USB 3.0 is capable of data transfer speeds up to 5Gbps. USB 3.0 is also known as USB 3.1 Gen 1 (5Gbps).

USB 3.1 is backwards compatible with USB 3.0 and USB 2.0, except in the following scenarios:

  • USB-B 3.1 cables are not compatible with USB-B 2.0 ports.
  • Unless you use an adapter, USB-C ports or cables will not work with USB-A or USB-B ports or cables.
  • Devices that require USB 3.1 transfer speeds of 10Gbps might not work with USB 3.0 or USB 2.0, or you might experience lower transfer speeds and impacted performance.
  • Bus-powered USB devices that requires more power than what USB 2.0 can provide are not compatible with USB 2.0.

To transfer data at speeds of 10Gbps, you need to confirm that the following components in your setup support USB 3.1:

  • The USB host connection
  • The USB cable
  • The USB device and any subcomponents (for example, a hard drive docking station and the hard drives in the docking station)

Note: USB 3.1 is also known as USB 3.1 Gen 2 (10Gbps). Devices that support USB 3.1 should have the USB 3.1 symbol on them. If the USB 3.1 symbol does not appear on your USB source or device, refer to the information provided by the manufacturer to confirm whether the USB source or device support USB 3.1.

The included USB cable for this USB 3.1 Gen 2 device has been tested and verified to perform at USB 3.1 Gen 2 speeds of 10Gbps.

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.

Great enclosure, but have issues.

By: Pitman77 - 02/20/2019
This is the second one I've bought, I love these enclosures, super fast and so far very reliable. My only issues is that the power supply is not working, I verified that it works using the power supply from the first enclosure I bought. Also did not come with the stand.

Easy to use, and fast

By: Ar41 - 08/03/2020
The first one worked without a hitch, housing a Seagate IronWolf 16 TB NAS (i.e. 24x7x365 drive), and it has been running for days without problems. Added a heat sink externally, this lowers the surface temperature somewhat. Performance is really good, typically 250MB/s disk-to-disk in Windows 10 using USB 3.1 interface over a good PCIe USB 3.1 two-port card.
