I have a samba share located on a Router USB storage DD-WRT V24 USB drive. I try to copy a file from a MAC OSX machine using Finder. Finder returns the following message: "can’t be copied because there isn’t enough free space." Even though there is plenty of space. Finder can read file from Samba share. Using Terminal, I can read AND write from and to the Samba Share. It looks like there is something about finder. All directories and files have permission "777" so permission should not be an issue. The share is "public" therefor guest access works fine. Using Ubuntu, Windows 7 file browsers, I can read and write files without any issue. Why Finder can't write file while terminal can?
EDIT (added information): This brand new 2TB USB drive used for the share has been formatted in EXT3 using Ubuntu Disk Manager. Finder Status bar shows "Zero Byte available" which is not true since there is almost 2TB available and I can copy files from terminal as well as Windows and ubuntu machines. Is there any incompatibility between Finder and Samba and or EXT3 format?
EDIT2: (more test result) User16081's comment gave me some test idea. I just connected the USB drive on Ubuntu Workstation instead of the DD-WRT router. Now I can copy from MAC Finder and Finder Status Bar shows a valid size "1.86 TB available". Looks like DD-WRT samba server has some kind of incompatibility with MAC OSX Finder. Any idea for a workaround?
Edit3: I used terminal with "df -h" to know the size of the mounted volume. I mounted the same USB drive on a Ubuntu machine and after on my DD-WRT router. I get a very different result. The size OSX terminal reports when mounted on Ubuntu is correct while, it reports only 20MB when mounted on DD-WRT. This is shown on the 2 last lines.

EDIT 4 I ran a similar test from a Ubuntu Workstation. It turns out Ubuntu sees that the reported size does not make sense and report proper used space but unknown available space and accept to copy files.
This sounds like samba server on DD-WRT is not reporting disk size or available space properly. MAC OSX Finder decides it can't try copying files while Ubuntu tries it anyway. The problem sounds to be coming from DD-WRT samba server. Any idea how to solve this? I did look extensively on DD-WRT forum and no luck.
I found a YouTube Video where it shows an Asus router (I use TP-Link TL-WDR3600) with DD-WRT V24Sp2 like mine having the same drive size (2TB) shared and we see the proper available space displayed in Finder. Nothing special was done during configuration. Other than using a different router, his disk has HPFS/NTFS format instead of EXT3.
