Hi,
I can confirm this does actually work.
Re-tried it when the little one went to bed last night.
Things are always easier when she constantly under my feet lol.
Thanks

Made some progress. Formatted the drive to NTFS and that sped things up considerably. I assume the wiki uses FAT32 specifically for flash drives and windows compatibility, though I'm not sure why they don't suggest exFAT.

Right now I'm working on testing if exFAT is faster or slower than NTFS.

I wish I'd known the usbromservice was more accepting of different file systems from the get go.
