Hello,

I recently bought a NAS-345 and wish to copy data from eight USB2 hard drives onto the NAS. They are all plugged in via USB hubs into my computer, and from there I was copying the data onto the NAS via ethernet.

At first, I was able to transfer about 500GB onto the NAS via this method. However, data transfer became incredibly slow after about a day of copying (i.e. in 12 hours, left over night, 100KB had copied TOTAL). I have also just tried deleting 100kb of text files in a single directory on the NAS and that has made no progress in the last three hours. Despite numerous reboots of the router, NAS and computer.

Are there any known issues with this? The computer had not gone to sleep or anything like that.

After this point, I have also been unable to do anything with the NAS either, e.g. it takes *hours* to load the contents of a folder when opened via Finder (on the Mac) or Explorer (on Windows).

So, I figured that I'd try and copy files from the USB drives onto the NAS directly by plugging each drive into the USB port on the NAS. I went into the USB backups settings page, and the tips on the side of the Web GUI state: "USB Backups also allow you to backup data to a NAS [from a USB device]". However, when I tried to choose a source (i.e. the directory on the USB HDD to copy onto the NAS), I get a blank list, as if the NAS didn't detect my HDD. But in the USB device settings, it detects the drive and says it is mounted.

I thought it may be caused by an incompatibility (i.e. the drives are 1TB in size and thought that may have caused an issue); I tried with an 8GB USB stick and I could then select that. But that doesn't solve my desire to copy files from my 1TB drive... My USB hard drives and the memory stick have the same file system (i.e. Mac OS Extended) - not FAT or NTFS.

Any ideas on how to fix these two issues?

Thanks in advance.  



Additional notes regarding administrator password issue under firmware version 1.00:
I had issues when first setting up the NAS under the original firmware (as shipped), so figured I would post this here as well so that people looking for this issue in future can find it via Google.

When installing the software under Windows 7, the installer kept freezing at various steps AFTER the step in which you define the administrator password. This meant I had to force-quit the installer. This meant that the installation had changed the password, but it led to corruption of the settings on the NAS, so that when I retried the installation, the installer prompted me for the default administrator password (which should be blank) but a blank password didn't work. However, entering the password that I first gave it before the installer froze the first time also didn't work. The only solution was to do a system reset via the reset button at the back of the NAS and then use the Web GUI to update the firmware to v1.01... and then I completely avoided using the software that came on the CD with the NAS altogether and just used the Web GUI. Hope this gives someone a hand in future.

Ok, so I just managed to get one of my 1TB drives to talk to the DNS-345. Got it set up under the USB backup settings. However, despite having it set up to perform the backup, the status message just shows "---" rather than "copying" or "error" (or anything else)... and the HDDs don't sound like they're active. My guess is that it's doing nothing.

I hadn't realized, but by having the LED display on automatic turn-off mode to save power, it wasn't showing me the on-screen prompt (on the NAS itself) to commence the backup procedure.

So I pressed the go button on the NAS and it then showed an animation of the backup happening, and three seconds later it said "backup complete". Three seconds to backup 1tb? Yeah, right.

I checked the NAS via the network drive in Finder/Explorer and it showed that it had created a backup folder where I told it to, but it just didn't actually copy anything over.

So I can only conclude that this is what DLink call a "backup"...?

Ok, update. Have been onto tech support.

They reckon the DNS-345 can detect drives with that file system (Mac OS Extended) but can't read files from it (and, therefore, it detects zero files to backup onto the NAS).

They also advised my slow transfer speeds are because uploading files to the NAS hogs 100% of CPU resources (as shown in the on-board task manager thingamajig). However, I am still having excruciatingly slow transfer rates even when I am not writing to the NAS at all. i.e. 5+ minutes just to open a folder on the NAS.

The saga continues...
