Cannot Write to USB HDD on RN314

That is the latest BIOS.

It may be useful if you can try reformatting the USB disk to see if that resolves it.

With 6.2 (coming soon) you will be able to reformat the USB disk from the Dashboard.

OK. A few interesting developments. I hooked it up to the PC, and ran a ChkDsk in Windows 7 on it. It found 4 files it was unhappy with the name (had a pipe symbol in them). Could not delete from Windows 7. Hooked it up to the Mac, and it only displayed the filename from the point after the pipe symbol. I was able to delete the 4. Went back to the PC, and ran ChkDsk (from the Explorer properties), and it still had the errors on the same files in the index section. I said to Fix automatically, and now it says no errors. I cannot write/delete/rename in Finder, but I can rename/delete in ReadyCloud. (I did have to set the permissions to Read/Write for Everyone again.)

Data on disk is important. My VB program detects new/changed files, and creates a time-stamped sub-folder, and moves the current backed-up copy to it before copying the new one. I would want to copy its contents first before re-formatting it. I noticed that there is a lot of useful information in this post that you have been involved in: viewtopic.php?f=4&t=77827&p=439361&hilit=external+usb+hdd#p439361. That is why I ran the ChkDsk.

Question: is the Hardware Compatibility List applicable to External USB drives? This Seagate is not on it, but neither is it on my NV+ HCL. I have another external dock and a spare drive that I will try to see if it is a defective RN314 first, however.

To be continued....

... Sooner than I thought. I just cannot write to it from the Mac (Probably a Yosemite thing???) However, on my XP PC, my VB Archive program is just chugging away.

Hmmm....

The HCL is for internal drives though a drive not suitable for use inside the NAS might in some case also be a poor choice in an external.

Thanks. I contemplate whether an external drive hooked up to the 314 is really the correct thing to do. I know of no backup software I could run from it that functions like my VB program. Back to my Rsync and Alerts issues.

I can write from the MAC now. It needed a restart. All the PCs are happy, and my XP VB6 program is just fine. (It even handles the Extended Attributes the MAC puts on files now and then, which Windows Explorer, nor Robocopy can handle).

I ditched the purchasing the external drive mentioned above, and am getting another 2 TB (so 32-bit XP can see it),WDC Red drive from the HCL (which means I now have 4 of them in my 314 and 1 spare) to put in a 3.0 external enclosure from OWC: Mercury Elite Pro FireWire 800 & USB 3.0/2.0/1.1 Enclosure Kit - Supports all 3.5" SATA Hard Drives up to 6.0TB. Heard that a lot of 3.0 enclosures go down to 2.0 on a MAC with a 3.0 port.

USB3 compatibility is not as mature as USB2 is, as you can see from your reports regarding USB3 drives on Mac going down to 2.0 speed.

There's still some way to go before it gets really good. But then there is USB3.1 which is a change again.
