Attached NAS drive extremely slow to connect and fails to reconnect

I have two new macbook airs yosemite 10.10.2, and a 4 year old windows 7 computer. I run a 4tb WD live duo Nas drive through a Apple Airport Extreme Router operating in Bridged mode. I have a 2 tb USB 3 backup drive attached to the USB media port on the Apple Airport Extreme Router Both Computers are connected via wifi.

When I turn the Macbooks on and Open Finder or Forklift I can see both the Airport Extreme and the WD Live Duo Nas drive icons in the shared devices area. When I click on either one in finder it can take up to a minute to see the shares and another minute or more to mount the shares then a few more seconds to see the contents, the another minute to see the contents of each folder. Once they are finally visible they can be accessed read and written to quickly as you would expect from a network drive.

In Forklift this process is reduced to about 5-30 seconds per section much better than finder but even forklift won't reconnect at login.

When I turn on the Windows 7 machine the mapped network drives work are attached and data immediately available, almost instantly as you would expect any network drive to work.

When I turn the Apple computer off then on again the Airport Extreme folder and the WD NAS Shared again show in Finder and Forklift but I have to again go through the slow process of mounting the shared drives again with the same long timeframes applying. I have not been able to find anything in any forums that tells me how to have the shared folders reconnect and be ready for use automatically.

I have tried putting the shared drives into user login items but while this works it opens the folder every time at startup and I then have to close them until I need them a most unsatisfactory arrangement.

The WD My Cloud access to the same NAS Shares on my network is all but instant as I would have expected the direct link to the NAS Shares to be.

This problem seems to be since Yosemite.

Am I missing something, or is it just too bad its a mac?

How do I have shared drives automatically reconnect and be ready for action at startup?

Is this normal for any Mac attached to any network if so it must be **** for users?

MacBook Air (11-inch, Early 2014), iOS 8.1.2

Wanted to chime in that, at least on my Cisco NAS, I was able to mitigate the problem by going into the NAS settings and turning off AFP (Apple Filing Protocol). We lost all our shortcuts and favorite links to shared folders but everything seems like it's back to normal.

My coworkers are very happy.

thanks I think it is just a Western Digital problem They don't integrate well with mac and there available setting tweaks are all but nonexistent

Does anyone know if this is likely to be fixed on El Capitan?

I have a cheap enclosure with a 4TB WD external drive attached through USB to my airport Time Capsule and it is incredibly slow. Time Machine is proceeding at excruciatingly slow speeds. And my mac is WIRED to this Time Capsule!

Slow & Crashing Explorer on selected systems:

I have a Mac Mini (Late 2012) with OS X 10.11. I have an attached 12TB Lacie Thunderbolt drive (also with USB compatibility) connected to the Mac Mini. The drive has been setup with SMB and given the appropriate permissions, however.. the issue is.. some windows machines can see the drive and other Windows machines cannot.. For example one Windows Server 2012 R2 Operating system will hang with the waiting glass for at least 30min to never before it shows the drive and only IF it shows the drive were a Windows 8 machine may work but an 8.1 may not... usually a clean install will hang first time... The drive is formatted in HFS extended (journeyed).

Any ideas what could cause this?

For the systems that do work I get timeout issues, slow transfers (not all the time however), and Windows Backup tools or VMware backup tools like ALTARO VMBACKUP will error out..

Well, I have a high spec iMac bought at the beginning of the year, and El Capitan certainly hasn't done anything to improve this slow access to NAS drives, both in locating them when rebooting/ restarting and when accessing the files on them.

I have 2 NAS drives :

QNAP 219PII (used as server for my Naim NDS streamer) with 4TB drives

Files structure Artist > Album > Tracks (i.e. 3 levels). Has 3 TB of music files at present.

WD MyCloud - only 5 months old. (used for everything else)

File structure a little deeper, but not much

Both have this very slow access problem. The iMac has always been very slow to access the content of these drives, and El Capitan is no better than were Mavericks and Yosemite.

To cap it all, the El Capitan upgrade completely 'broke' the access to my NAS drives, with multiple 'couldn't access drive' type errors, even though both were visible in Finder, and I have just spent several hours sorting it out. I couldn't even rip a CD (using dBpoweramp MAC) before doing this, as all I got were error messages, even if I 'temporarily' managed to mount the drive using Finder > GO.

For the QNAP, I managed to sort it out by updating the QNAP firmware, activating ivp6 (?), and remounting using Finder > GO

For the WD MyCloud I eventually finished up to a WD Cloud system reset (didn't want to have to put all the files back on it!), then deleting every bit of WD software I could find, then reinstalling the drive, and setting a Static IP address for it.

Seems to be working now, but only time will tell.

Purely as an aside, I have NO problems accessing the NAS drives using Windows 10 in Bootcamp.

I was hopeful, but after upgrading to El Capitan, I agree that El Capitan still has not fixed this problem. Very frustrating!!!

i have the same problem ,

we have in my company Lan and as server we have a nas (omninas shuttle kd 21).

The most pc's who have windows os works perfectly and faster with Nas , but the mac computers are very slow regarding the speed with the same nas.
