How to access data via USB
I've posted a separate topic on probable failure of my ReadyNAS Duo's network card.
In the meantime I've got important data I need to get off the NAS. I tried plugging my laptop directly into it via USB in the hope it would recognise it as a USB device and give me access to the drive.
But no luck, so I wondered if it's possible to access the data any other way other than via the network card?
I did pull one of the disks out and attach it to a Win7 PC as a second HDD, but it wanted to format the disk so I guess it is not formated as NTFS in the NAS.
Thanks
Ian

- You can't access Duo via USB cable and also Duo is running Linux so it will be not recognized under Windows.
You still can access your data but it requires Linux know how. If you have Linux machine you can and you know what LVM is then you can access your data.
Otherwise I would strongly advise to contact support if you still haven't or get in touch with someone who knows what LVM is. - Thanks bbaraniec - I thought it was a long shot with the Win7 connection but I have urgent financial stuff I need daily on the NAS so thought I'd give it a go.
Thanks for the LVM pointer - I may be able to get a Linux machine, and someone (not me) who knows how to work it.
Does the LVM connection run via the USB port of LAN card? If it's the LAN then that looks out of action so I'll have to wait until that problem is fixed. - You will need to take our drives from Duo and "mount" then in any Linux supporting LVM.
Make sure that whoever will be helping you out knows what he/she is doing!
You can read more about LVM here: http://en.wikipedia.org/wiki/Logical_volume_management
Basically your HDDs are PV (physical volumes) they are in VG (volume groups). In VG is/are LV (logical volumes).
PV1 PV2

LV1 LV2 LV3
ReadyNas has one VG called "c" and within it one LV "/dev/c/c" - Do you have USB-HDD?
You can plug USB HDD to the NAS then set a backup job from 'share folder' to 'share:USB_HDD" or USB device"*** port" - I do have a USB-HDD, but the problem is how do I access any sort of GUI interface to run a backup job without being able to use the LAN port?
Unless the 'backup' button on the front of the NAS would dump all the data from the NAS to an HDD connected to the USB port on the front? You can program the Backup button on the front of this device to execute one or more backup jobs that you have defined above. The jobs will be executed in the order that you specify here when the Backup button is pressed. If no jobs are selected for the button, depressing the button will backup the content of the backup share to the storage device connected to the front USB port.
So this isn't solution.
