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.

Before You Buy

Hard drive enclosures require power from your system's USB port. Although you can plug in any standard SATA drive, USB ports only supply a limited amount of power and are not able to power all of the hard drives plugged into the system.

The power capabilities of the USB port combined with the power requirements of the attached hard drive will determine if the hard drive enclosure will work in your setup. The power (in mA) supplied by the USB port must be greater than the requirements of the hard drive.

A USB 2.0 port can supply a maximum of 500 mA (0.5 A), and a USB 3.0 port can supply a maximum of 900 mA (0.9 A).

You can usually find the power requirements of your hard drive in the technical specifications on the label of the hard drive or on the manufacturer's website.

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.
