No filesystem on USB NTFS drive that worked perfectly fine
I disconnected a 1TB USB seagate drive from my ReadyNAS Duo v1. The drive was working totally fine and formatted as NTFS. I keep all of my movies and video files on it. I connected the drive directly to a linux machine I've got, but never even mounted the drive successfully (I am not fluent in linux and didn't have time to figure it out). So I disconnected the drive from my linux box and plugged it into my Mac running Snow Leopard. The drive popped up and all of my files and folders are there.
Then, I eject it from my Mac and plug it back into the ReadyNAS. The Duo sees the drive, but in the USB volumes page in Frontview it says it has "No filesystem." This doesn't make any sense to me. It worked just fine 15 minutes ago, but simply unplugging it and plugging it back in makes the Duo unable to recognize the file system.
To troubleshoot I double checked the drive by plugging it back into my Mac and it once more recognized the drive. I plugged it back into the Duo and rebooted the NAS but got the same results "No filesystem." I tried both of the rear USB ports and got the same result. The front port is currently in use by another USB drive so I couldn't try it. But like I said, it was working fine plugged into the rear port earlier.
I'm running Raidiator 4.1.10 and I just rebuilt the NAS from scratch so it's all pretty stock at this point. The only add-ons I have installed are Twonky and iStat but I don't see what those could have to do with anything.
I downloaded the log files and here's all I found that seems relevant (but still not that informative) from user.log
I can post any other logs if they could help.
In summary...I got problems. Any advice?

- You could try restarting the duo with the USB drive attached.
- Thanks stephenB. Tried that :D Any other suggestions?
- I just tried to clean the USB list using the Clean_USB_Storage add-on as a long shot. No help.
I plugged the drive back into my Mac and again, all the files show up no problem. Disk Utility says the disk is formatted NTFS with 1 partition. The Partition Map Scheme is Master Boot Record. - Problem solved! I plugged the drive into a Ubuntu system and it told me there was a problem with the file system and it suggested that I run chkdsk /f on a windows machine. I did that and viola, I'm back in business and all of my files are there. The ReadyNAS recognized the drive after I ran chkdsk and I'm backing it up right now in case it's on the edge of failing. I should have thought of chkdsk before, but I'm glad I got it.
