# Troubleshooting Filesystem type exFAT not configured in kernel message on the NextSeq 1000/2000

Solid State drives for external data storage may be formatted as an exFAT system. However, this format is incompatible with the NextSeq 1000/2000, and attempting to mount such a drive will result in errors such as "Unable to access drive, Filesystem type exfat not configured in kernel."

Reformat exFAT-formatted drives to the compatible format NTFS to allow the drive to be mounted correctly on the NextSeq 1000/2000.

**To reformat a drive:**

1. Transfer the drive to a Windows computer.
2. Right-click the drive in a file explorer window.
3. Select **Format**.
4. Follow the prompts to format the drive as NTFS.
5. Reconnect the drive to NTFS and mount the drive as explained in the Knowledge Article [Networking and output locations on the NextSeq 1000/2000](https://knowledge.illumina.com/instrumentation/nextseq-1000-2000/instrumentation-nextseq-1000-2000-reference_material-list/000003037/?utm_source=agent\&utm_medium=email\&utm_campaign=kb)

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://knowledge.illumina.com/instrumentation/nextseq-1000-2000/instrumentation-nextseq-1000-2000-troubleshooting-list/000007105.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
