Unable to mount Mediasonc Proraid HUR5SU3 USB drive(s)

[ankitrana]

Hi,

I have a mediasonic proraid device with two HDD (4TB each) configured as single to show up as separate USB devices.

I have used this before and it used to work perfectly, and now for some reason it does not show up both devices but randomly shows up either 1 of 2 HDD as usb.

I googled around and some suggested to SSH and mount the device but that is not what i want to do... hesitatingly i SSH into the ready nas. With absolutely limited knowledge of anything tech is just found out that it is indeed discovered but not mounted.

I have another Seagate USB plugged in and thought may be it is due to another USB attached, i tried it with Seagate USB connected and all the USB ports but the result is same.

SBPD is Seagate backup plus device (another USB)

T3 and T4 are the two disk label for Mediasonic USB device

i dont even know how to mount them and is looking for some guidance. If need more outputs to be shared please share the command as i might know how to do that

TIA

The NAS does support NTFS (your other drives are formatted that way).  But it does use a third-party package to do that.

I'm guessing it might be the Paragon software.  If I'm right, then 

# mount -t ufsd /dev/sdg2 /media/USB_HDD_3

might work.

[StephenB]

As you can see from the df command, normally it would be mounted as /media/USB_HDD_x

So you can look in /media, and find a USB_HDD folder that isn't being used (for example USB_HDD_2), and try mounting with

# mount /dev/sdf2 /media/USB_HDD_2

Then see if the expected files and folders show up in /media/USB_HDD_2.

However, this might not be enough to access the drive with file explorer or the web ui.

Hi there, first of all thanks for your response, really appreciate it.

So i had all the USB drive plugged out, so after pluging in "the USB", this time around the other drive came up.

so i modified your command and ran

root@BhaiyaJi:/home/admin# mount /dev/sdg2 /media/USB_HDD_3
mount: mount point /media/USB_HDD_3 does not exist
root@BhaiyaJi:/home/admin# ls /media/
USB_HDD_4

so i created a new folder and tried to mount

root@BhaiyaJi:/home/admin# mkdir /media/USB_HDD_3
root@BhaiyaJi:/home/admin# ls /media/
USB_HDD_3  USB_HDD_4
root@BhaiyaJi:/home/admin# mount /dev/sdg2 /media/USB_HDD_3
mount: unknown filesystem type 'ntfs'

So there you have it....well why does it say so ??

Yes that did work, i can access all the folders and it seems it has all the data.

And as you said they did not appear in the GUI or shared folders list...

Can you help me to fix this issue, it should have mounted and available accross share automatically

Sorry, I don't know an easy way to get it to mount and share automatically. 

Since this worked before, it sounds like a bug in 6.10.2.  Perhaps the mods ( @JohnCM_S or @Marc_V ) will have a suggestion and/or can follow up with Netgear development.

[ankitrana]

Thanks @StephenB appreciate your help.

@JohnCM_S and @Marc_V can i look up to you for further support ?
