# TntDrive

TntDrive mounts a Zata bucket as a network drive on Windows. The bucket gets a drive letter in **This PC**, and you use it like a local disk.

## Before you start

* A bucket — see [Create a bucket](/buckets/create-a-bucket).
* An access key from the same region as the bucket — see [Access keys](/access/access-keys).
* TntDrive installed — [download TntDrive](https://tntdrive.com/download.aspx).

## Test it

Copy a small file onto the new drive. Check that it appears in the bucket in the Zata console under **Buckets**. Then copy it back to a local folder to check that downloads work.

## Troubleshooting

| Problem                              | Fix                                                                                                                                           |
| ------------------------------------ | --------------------------------------------------------------------------------------------------------------------------------------------- |
| The bucket list is empty             | Check that the REST Endpoint matches the region of your key. Sub-user keys never list buckets — type the bucket name in **Amazon S3 bucket**. |
| Access denied or invalid credentials | Copy the keys again from **Access Keys**, without extra spaces.                                                                               |
| Connection errors                    | Make sure the REST Endpoint starts with `https://` and **Use secure transfer (SSL/TLS)** is ticked.                                           |
