Backup to USB fails due to lack of space; but it's an empty drive and there are no files on it!
I've upgraded my NV+ v1 (4.1.14) with 4x 2TB drives and I ran into the 4k block size problem. So I'm trying to backup my device so I can factory reset it.
The current size of the volume is 1.3TB, so I took out one of the 2TB drives to use as a backup via USB. 1.3TB should fit easily into 2TB, right?
I added the 2TB drive to the front USB port and formatted it as ext3, it shows up just fine in the shares and has the expected free space.
So I made a backup task and source=share/ dest=USB/Sharename/ and ran it.
it runs for a few minues and stops with this error:
Error encountered copying data from source path ==> /USB_HDD_4_1//blah due to lack of disk space. [Job 003]
I look at the USB drive and it is FULL. Zero bytes available. It has made a few folders, but they are all empty.
What is going on?
Are there hidden files (.appledouble, etc)? I ran BlueHarvest on the volume before the backup and it deleted a bunch of these. But not 2TB's worth.
I use this volume mainly with my mac... is there anything I'm missing?
Any help is appreciated! Thanks
OK, I figured out the multiple partition problem.
When partitioning a drive with Disk Utility on Mac, it creates a HIDDEN FAT32 partition called EFI which is used for some boot info. This EFI partition is confusing RAIDiator and causing it to try and use the small EFI partition instead of the large main one.
Since I'm not booting this drive (it's only for backup), it's safe to remove it. You need to enable a debug option in order to see the partition in Disk Utility. Search google for 'Remove EFI partition on mac' to see how to do it.
Also, I used EXTfs for mac by Paragon Software which allows you to create and mount ext3 partitions on your mac. http://www.paragon-drivers.com/extfs-mac/
Backup job is running now... hopefully it will complete successfully!

Hello JanSolo,
Did format the disk before plugging it to the USB port? What's file system format?
Regards,
- I used the usb volume page in raidiator to format it as ext3.
Im gonna try to format it manually on my Mac, but macs don't support ext3. What should I use?
