USB Backup fails unmount... Maybe? CRITICAL

Please click "Sending Logs" in my signature.

Thank you. I will send logs and continue to update this thread.

Since I last posted I've amassed more information on the ReadyNas's condition.

The scheduled backups (two jobs going to USB drives HDDA and HDDB) were attempting to write to the RAID volume, thus filling it.

I deleted both backups and deleted the HDDA and HDDB shares that were created.

I installed USBClean and rebooted. Same behavior the next day.

I installed SSH and poked around (gently) to see if I couldn't find some config file that was causing the problem.
Installed apt-get and then performed the dreaded upgrade which required that I reinstall the firmware.

Which I did and now I'm back to square one. No SSH, no backup jobs.

Here is what confuses me. When I plug in the USB drive, the USB storage page shows USB_HDD_1 and USB_FLASH_1 even though there are no flash drives connected to the ReadyNAS.

I really think something is wrong with the USB settings or the USB drive itself.

I'm currently testing with another USB drive/enclosure.

Also, I get "UPS has been disconnected." errors when the UPS is in fact connected and is certainly compatible.

Further info:

NV+
Firmware: RAIDiator 4.1.10 [1.00a043]
Memory: 1024 MB [2.5-3-3-7]

Further further info:

I cannot format the replacement USB HDD I plugged into the front usb port.
The drive in question is a 500GB Seagate formatted NTFS in a generic USB2.0 enclosure.

Which USB enclosure do you use?
I checked logs, there are some error for USB device,

2x Bytecc 3.5" esata/usb SATA enclosure (the one with the penguin leds)
2x Seagate 1TB 7200RPM SATA 3.5" HDDs.

1x generic USB2.0 enclosure (maybe Bytecc as well)
1x 500GGB Western Digital 7200RPM SATA HDD.

None of them mount. Cannot run a backup.
To me it seems that the problem is in the NAS settings rather than all three drives coincidentally exhibiting problems.

Let me know what else I can do to help you help me.
:)

Hi Davide-NYC,
I don't have Bytecc 3.5" esata/usb SATA enclosure to reproduce the issue.
Could you open a technical support case here?
