### Describe the bug

I am trying to download the `librispeech_asr` `clean` dataset, which results in a `FSTimeoutError` exception after downloading around 61% of the data.

### Steps to reproduce the bug

```
import datasets
datasets.load_dataset("librispeech_asr", "clean")
```

The output is as follows:
