Windows reporting incorrect drive size attached to NAS adapter

I am new here and wasn't sure where I should post this as I can see it applying to multiple categories.

I have two NAS storage adapters, both are CiragoLink+NUS2000 Devices. Each unit accommodates 4 USB hard drives up to 2 terabytes per attached drive. On both devices I have attached Western Digital external USB hard drives ranging in size from 500GB's to 1.5TB's.

The issue I am having is; if I "Map a Network Drive" to create a shared directory on any of the drives attached to the NAS adapters, Windows reports both the total disk size and free space available incorrectly. e.g. all of the attached drives show up in Windows explorer as having 55MB's of 62MB's available, when in fact it should report several hundred gigs available out of around 1 terabyte.

So not sure if this is a Windows' issue, an issue with the NAS adapter or if it's user error. Just an FYI, I get the same results on any PC, Windows XP or 7 when trying to connect to any of the drives.

Because of this issue, Windows' thinks the drive(s) is almost full and will not let me copy data to them.

Can anyone help me understand what is going on here? Thanks for the help.

Welcome to Sevens Perry!

Your best bet for this specialty hardware is to call the company that makes it.

I had some ideas, but then looked up the piece of hardware, that's your BEST option for timely manner troubleshooting.

Web site:

CiragoLink+ « Cirago

There is a firmware update to v2.30 for a NU2000 there, also.

Not a NAS user ever here...

Thought it was odd that USB drives would be used with NAS anything, but I was thinking of the ones with direct slots you just put internal drives in.

I looked up that adaptor, I use a USB hub (with it's own power source) for usb external drives, but only to one PC, and then other method for sharing if networked, like home group could be tried for sharing, but that's not helping if using non-Windows devices.

I would keep calling tech support until you get someone, and look for OTHER phone numbers to reach them, so bogus sometimes, one # will get actual person, other gets a voice mail [other company].

In the meantime though I would upgrade the firmware and try again, if not done already.

That part is not likely one that Windows normally recognizes, so it could be a driver issue.

If you plug one of the drives into your PC's USB port (any) what size shows up?

In case you missed it, I added a comment:

If it gives the right size on all your drives that way, then yeah you need to discuss this with them, for sure, unless you need to just add the drivers off their web site to run the NAS adaptors.

The NAS itself thinks they are sub 100gig drives though based on what you said.

If empty drive, sure I'd try formatting one that way, quick format is a matter of seconds, any how.

FAT-32 btw can't handle over 4gig size files, just beware, that and no file policy protections available. :)

So the NAS hub sees them right....

How are those attached to a PC to network them?

I would skip the 3TB drive then since it's not usable with that device limitation.
