Frequently Asked Questions - S351BMU33ET StarTech.com

What type of hard drive can I use with the S351BMU33ET?

The enclosure supports any standard 3.5-inch SATA hard drive (HDD). It does not support 2.5-inch drives or IDE drives.

How do I install a hard drive into the enclosure?

Turn off the enclosure, open the door, insert the drive with the label facing up and the connectors facing inward, push gently, close the door until it clicks, and optionally lock it using a pen. Then turn on the enclosure.

What do the LED indicators mean?

A solid blue LED indicates that the drive is receiving power. A blinking red LED indicates that the computer is accessing the drive.

Can I use both USB 3.0 and eSATA at the same time?

No, you should connect only one interface at a time. The enclosure has separate ports for USB and eSATA, and you choose which one to use based on your computer's port.

How do I prepare a new hard drive for use in Windows?

Go to Computer Management > Disk Management. Initialize the disk (choose MBR or GPT), create a new partition, and format it. The drive will then appear under My Computer with a drive letter.

How do I prepare a new hard drive for use in macOS?

Open Disk Utility, select the drive, go to the Partition tab, add a partition with a name, and click Apply. The drive will appear on the desktop.

How do I safely remove the hard drive?

In Windows, use the 'Safely Remove Hardware' icon. In macOS, drag the drive icon to the trash. Wait for the activity LED to stop blinking, unlock the door (if locked), open it, and gently pull the drive out. Always power off the enclosure first if possible.

What power adapter does the enclosure require?

The enclosure uses a DC 12V power adapter, which is included in the package. Do not use a different adapter as it may damage the device.

My computer does not recognize the hard drive. What should I do?

First, ensure the enclosure is powered on and the cables are connected properly. If the drive is new, it may need to be initialized (see initialization steps for your OS). If still not recognized, try a different cable or USB/eSATA port. Check Device Manager (Windows) or Disk Utility (macOS) for unrecognized disks.

Is the door lock secure enough to prevent theft?

The door lock is not a robust security feature; it is designed to prevent accidental removal. To deter theft, do not leave the enclosure unattended in public areas.

Prepare a hard drive for use

Windows OS

If you install a hard drive that has data on it, after you connect the drive enclosure to your computer, the hard drive appears under My Computer or Computer with a drive letter assigned to it. If you install a brand-new hard drive that doesn't contain any data, you must prepare the hard drive for use.

Warning! When you complete the following steps, all of the data on your hard drive is deleted. If your hard drive has data on it that you require, you should create a backup file or use a different hard drive.

1. Depending on the version of Windows® OS that you're running, do one of the following:

2. On your desktop, right-click My Computer and click Manage.

1. Locate the disk that is labeled Unallocated. To confirm that the hard drive is the correct one, check the drive capacity.

2. Right-click the section of the window that says Unallocated and click New Partition.

3. To initialize the hard drive in the format of your choice, complete the on-screen instructions.
