Extrenal Hard Drive with Raid 1 option won't mount through Airport Extreme

I just purchased the new Airport Extreme and the Iomega UltraMax Desktop Hard drive, 1TB. The hard drive has Raid options. I plugged the hard drive into the back of the Airport Extreme through USB and if I have the hard drive set up to be Mirrored (Raid 1), the hard drive will not show up on my desktop.
I switched the hard drive back to Striped (Raid 0) and it shows up. However, if I open the Airport Utility, the hard drive doesn't show up there. I also can't see the drive by going into the disk utility either so I can format the drive before using it.
Any idea why this doesn't work as Raid 1 through the Airport Extreme and then I'm puzzled with why it doesn't show up in the Airport Utility nor in the Disk Utility.
I want to be able to access this hard drive with a laptop eventually and I also want to make sure that I protect my data by using the Raid 1 option.
Can anyone please help me figure out these issues?

Sure. Forget about the AirDisk and buy one of these:
http://www.dlink.com/products/?pid=509 - It's a D-Link DNS-323 2 drive bay SATA NAS box, and shouldn't cost you more than $185 without drives. It has Gigabit Ethernet, supports SMB and AFP (it'll work with Windows machines and Macs), and it even runs an iTunes server inside the box.
http://preview.tinyurl.com/32vfc3 - Maxtor 500GB drives for $100 each shipped.
So for ~$385, you can have 1TB of space which you can then array as RAID 0 or 1, or use as a big, contiguous drive.

External hard drive isn't visible, won't mount

Hi,
I have a WD MyBook external hard drive that is not working correctly with any mac. It randomly stopped showing up on the desktop or in the finder. I don't move it around at all, so I have no idea what the origin of the problem is. I have tried plugging it into a black Macbook, white Macbook and Macbook Pro with the same results. It shows up in both the System Profiler and Disk Utilities. In the System Profiler, I can get information on the drive. The only thing I see of note is that there isn't a mount point. In disk utilities the hard drive is gray. When I click on it to repair it, I can only repair or verify the disk. When I do that, it tells me that the drive "appears to be okay". I try to mount it and it tells me it cannot be mounted and to try running first aid. I also can't eject it.
I'm at a loss at this point. Is there something else I can try?
Thanks in advance for any suggestions and sorry for the long post!

Had the exact same problem yesterday and wanted to share how I solved it. It first happened a couple months ago. Would not mount on my Mac Pro, but it did show up when I connected it to my laptop. I solved it by just shutting off the Mac Pro, unplugging it even, and unplugging everything from the My Book drive. I let it sit for 3 hours. Started the Mac Pro up, then put FW cord into My Book, then into Mac Pro, then connected the power cord for the My Book. That worked. For some reason.
But I tried that again when My Book Pro Edition disappeared yesterday (could see it grayed out in Disk Utility, but it would not mount) and nothing would bring it back. After looking through the Western Digital site, I figured it had something to do with the partition being bad. I thought I'd have to buy Stellar Phoenix data recovery software, which might have recovered my data. But first I went out and bought Disk Warrior. Disk Warrior fixed it! I'm back up and running.
My theory on why My Book Pro Edition had problems this second time. To save my on my electric bill I write this during the recession), every night after I shut down the Mac Pro, I also turn off the power strip. Cutting the cost of "vampire" electricity, as they say. Now I see I wasn't shutting down the My Book properly... you need to follow the Safe Shutdown instructions -- pressing Power Button once. Although I also have the My Book Studio connected which hasn't been affected by my turning off the power strip as it seem to shut off by itself when the Mac Pro is shut down. I think improperly shutting down the My Book Pro every night is likely the reason Disk Warrior diagnosed the problem as a "severely damaged directory."

What's the most recent opinion about Time Machine backups to Hard Drives connected to the USB port on the Airport Extreme Base Station (5th generation)?

I have been searching the Apple communities and Internet for a final answer. I just bought an Airport Extreme Base Station (5th generation) and LaCie d2 quadra 1TB external drive as a replacement for TWO failed Time Capsules, neither of which Apple would replace due to failed power supplies. I formatted the 1TB drive using Disk Utility (Mac OS extended (journaled)) from my MacBook Pro, and then plugged into the Airport Extreme Base Station USB port. The Airport Extreme Base Station see the Hard Drive, and my MacBook Pro sees the Hard Drive in my finder under shared resources. Time Machine, however, does not see the drive. Is there a solution for this problem? If Time Machine will not work, is there another software product out there that will work, like Carbon Copy. Having to plug the backup drive into the USB port of your laptop every evening kind of defeats the purpose of having a laptop. Any suggestions would be appreciated.

Keeping in mind that this is not supported by Apple, I have been successful at doing the following:
1) Format the entire drive (1 Partition) as Mac Extended (Journaled). You must click in Options and set it as a GUID Partition Table (first option)
2) Plug drive via USB to AEBS
3) Using Airport Utility, use Manual Setup, then under Disks, select the new Disk and click File Sharing, then Enable File Sharing and Secured Shared Disks (recommended, of course). Other settings are up to you.
4) IMPORTANT: you will NOT see this Disk in Time Machine until you open Finder and double-click on it. You will not need to do this again (hopefully).
5) Now it should appear in Time Machine. Remember to exclude any large files like Virtual Machines, since they will be re-backed-up (is that a word?) every time it changes in any way.
6) Remember that the first backup (over WiFi) is the longest. Leave the computer alone during this period.
Good luck, and let us all know how it went for you!

Ext hard drive no longer visible in Windows XP via Airport Extreme

Hey everyone,
I am running a Windows XP Pro machine in my network. I have a LaCie 500gb ext USB drive plugged into my Airport Extreme. It is formatted in Mac OS Extended. It has always shown up with my other drives on my PC under the "My Computer" window. Now it has disappeared out of nowhere. Nothing was installed/changed. I host files on that drive that I access from my Windows machine and I cannot for the life of me get it to show up again. I understrand that Windows doesn't read Mac OS Extended... If I plug the drive into my PC directly it does not show up. But for some reason it has always worked through the Airport until now... Was it just dumb luck until this point?
Anyone have any ideas?
Thanks!

HDDs, formatted in Mac OS Extended, are shared out using the SMB/CIFS file sharing protocol to Windows or Linux-based network clients. As you know this format is not readable when connected directly to a Windows PC.
SMB/CIFS is the common sharing format used by Windows to access any network drive so that shouldn't be the issue. Have you tried mounting/mapping the drive on the PC? Please check out the following Apple Support article for details.

Video Streaming in Windows media player won't play through Airport Extreme

Hello and thank you for reading my issue.
I have the current square shaped airport extreme base station. My mother has a Windows XP system on her Toshiba laptop and she takes an online class which has video streaming for the lectures. When we connect to the network wirelessly or with an ethernet cable through the base station, the video will not begin to buffer and won't play from the website. It just states ready and doesn't buffer. However, if we connect the laptop straight to our cable modem without the base station, the videos stream and play perfectly. Anybody know how we can fix this to play through the wireless network? Thanks a lot.
MacBook Pro 2.33 GHz Intel Core 2 Duo, 2 GB 667 MHz DDR2 SDRAM Mac OS X (10.4.8)

I've played with all sorts of software settings and configurations. This is what worked for me, but I'm not sure how it would work for anyone else, or if the issues are even related, but here goes.
1 - Turn multicast rate to 1 MBPS in the drop down menu found in Airport Utility>Airport icon>Wireless Options Button.
2 - Turn off multicast in Windows Media Player or Real Player
3 - Turn on Video Overlay Optimization check box in Real Player.
These things worked for me, hopefully they will help or give you some ideas for your own situtation.

SAP NetWeaver Portal won't open through AirPort Extreme

Hello,
I am trying to access this site: https://ess.sobeys.com/irj/portal
When my iMac is connected to the internet through our AirPort Extreme, the site will not load. It will also not load on any device (iPod, iPhone) connected to the network created by the AirPort Extreme.
When I bypass the AirPort and connect the iMac directly to the internet, the site opens.
Also, when I turn off the Wi-Fi on my iPhone and use 3G data, the site opens too.
I can not find any info online about this. I think it may have to do with ports on the AirPort Extreme.
Any help would be appreciated.
Thanks,
Patrick

It happens to me with one song, the only song of more than 2,000 that I've edited (I cut out the beginning, don't remember what program I used). I have no idea why.

Using an external hard drive with Airport Extreme

I'd like to use an external hard drive to store movies and music through my Airport Extreme. The drive is connected to a powered usb hub which is connected to the Extreme. I can see the drive in Airport Utility but I can't figure out how to use it.

Hi,
I have just tried to set up an Airport Extreme with an external hard drive at home. I have 4 computers connected to the "network" - an iMac, a MacBookPro and 2 x windows machines. A printer is connected wirelessly to the two Macs.
I cannot find the hard drive - I have tried the steps mentioned by Bob Timmons Mar 17 2010, but the only things I see under "Shared" in Finder are the iMac and the printer - not the Airport Extreme (seems odd??), not the windows machines, and most importantly, not the hard drive connected to the USB port on the Airport Extreme.
I therefore expect that the iMac and printer are connected wirelessly and directly, rather than through my network (& I'm happy for the printer to be connected this way, but I do need the PCs and the hard drive all networked).
According to my network connection, (in top bar on the screen) I am definitely connected to the network - yet nothing else shows in finder??
I do, however, see the USB hard Drive when I go into Finder>Applications>Utilities>AirportUtility.app, under my Airport Extreme >Disks. I've also gone through all the set up procedures for "File Sharing."
I have read other posts about formatting the hard drive ether FAT32 or NFTS - is this something I now need to do?? If so, which one should I use, and once I do it, will I then see it?
Presumably, in order to format the Hard Drive, I will need to disconnect it from the Airport Extreme, and connect it directly to one of the Macs too?
My apologies for so many questions, but this is all very technical stuff for the non-techie layperson.
Many thanks for any help anyone can provide on one or more of the questions / issues.

After replacing a failed hard drive with new one I inadvertently created a different account name(home/user) than the one in the Time Machine backup. Now I cannot restore the photos in iPhoto. What are my options?

After replacing a failed hard drive with new one I inadvertently created a different account name(home/user) than the one in the Time Machine backup. Now I cannot restore the photos in iPhoto. What are my options?

The best thing to do would be to start over. Use Setup Assistant this time.
Boot into Recovery, launch Disk Utility, and erase the startup volume. This operation will destroy all data on the volume. Quit Disk Utility and install OS X. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade, so make a note of those before you begin.
When you reboot, you'll be prompted to go through the initial setup process. That’s when you transfer the data from one of your backups. For a walkthrough, see here:
Using Setup Assistant
Don't transfer the Guest account, if it was enabled on the old system.
Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.

How do I remove one failing hard drive from raid set and replace with new one

Last Friday apparently one of my raid drives started failing.
As I mentioned on this forum I started getting continous beeping.
I was finally able to get the raid working at a degraded level. I ordered a replacement hard drive which is arriving today.
(In the meantime I made twice daily backups of my work.....)
Below was the message I got from the browser based raid software:

Blahblah 12    1000.2GB   RaidSet Member SamSung HD103SJ
(See this earlier thread if you wish!)
http://forums.adobe.com/thread/727867?tstart=0
At one point when I did the checked the browser interface I saw the message Failed and Degraded
As I said, I was able to work over the weekend on the degraded system.
This morning I got the beeping again and did the rescue and now I am running a "full raid" without the notice that one raid was "Free".
In any case, the new hard drive is arriving today.
What steps should I take to incorporate the new drive into the raid system.
I have one OS drive
and 4 tb raid drives.   One needs to be replaced with the new one that I am getting today.
Thanks

Harm,
Regarding your comment:
Re: How do I remove one failing hard drive from raid set and replace with new one
Please tell me how to read the serial number from an individual drive rather easily, without un-installing them:
If you select the proper drive to change out, you only need to remove one drive and look at its serial number...
Step 1: Identify bad drive serial number using Areca's tools
Step 2: Turn off the computer
Step 3: Remove what you think is the bad drive based on following your numbered cable method, marked hot-swap bays, whatever
Step 4: Verify that the serial number matches the "bad drive" serial number from step 1; if it does great, proceed; if it does not match, go back to step 3
Step 5: Change out the CORRECT drive - that's the bottom line for this whole procedure
Cheers,
Jim

Replace both Raid 1 hard drives with larger ones.

This computer came set up for Raid 1. I need to replace both hard drives with larger ones. What is the proceedure for doing this?

Hi wweksjk!: Yes you can have 2 HD's with differing capacities as an example on my Xion-MSI PC which was custom built in 2006 I had 2 Western Digital HD's, respectively 160 GB & 250GB divided into 3 partitions
the brand name isn't as important as the rpm the faster the drive spins your computer will be faster
also look at the size of the buffer on the drive as well because the higher the number there will speed up the boot time as well
however installing a new drive as the boot drive will be complex but if you follow instructions that come with the HD installation software it can be done
for example a 7200rpm drive is faster than a 5400rpm but not as fast as either a 10k or 15k model
good luck
hope this helps & enlightens you
Happy Holidays!

Why won't my new Airport Extreme recognize my USB Hard drive? My MacBook recognizes it. I already have had a great deal of trouble connecting my printer to print wirelessly, but finally resolved that. Now I want to add the external drive with a USB por

Why won't my new Airport Extreme recognize my USB external hard drive. I put a USB port on the base station, and the system recognizes my printer. When I click on disks - it lists my printer, and when I click on Printers it lists my printer. What do I need to do to get it to recognize the external drive? BTW, the MacBook recognizes it, no problem. I have erased it and reformatted it. I am running the new Lion OS. Any help is appreciated.

Yes, I saw a post on one of these threads about a powered USB hub so I ran over to Office Depot and picked one up. I was finally able to see the HD in the Airport Utility. Yay!

How can I partition an external hard drive with data in it? When I select the drive, the partition option is grayed out.

I am having a problem partitioning an external hard drive with data in it.
When I select the partition, everything is grayed out. I can't add a a partition for some reason. When I asked this question to other people, they told me to select my partition "io" to do it from there.
As you can see, I can't seem to partition it form there either. I ran the Verify Disk utility but the volume came out okay.
Any ideas as to what the problem would be?
Thanks!
Luis

Select the main hard drive entry (topmost one.) Click on the Partition tab. Shrink the existing partition by grabbing the sizing gadget in the bottom right corner and pushing up until you free up enough space for your second partition. Be sure you do not shrink to less than the space currently occupied by your files. Click on the Add[+] button to create a new partition in the free space. Click on the Apply button and wait until the partitioning is completed.

I made a bootable disc on an external hard drive, with Yosemite on it. I am running Snow Leopard on my iMac. How can I open the Yosemite disc from the desktop on my iMac? Does the external hard drive need to be connected to my iMac by firewire to do that?

Snow Leopard's Startup Disk pref can’t see Yosemite volumes. So the only way to switch from Snow Leopard to Yosemite is to do what Niel mentioned. Doesn't matter whether it's connected by USB or Firewire, although performance via FW would be faster.
Are you saying that Yos/10.10, as a volume located in a mounted external drive won't appear as an option in Snow Leopard's Startup Disc, in Sys Prefs? I've never heard this one before. AFAIK any mounted volume, regardless of OS, should appear there. I would think that, if it appears in the Boot Picker/Startup Manager it would also appear and could be booted to from Snow's Startup Disk. I can't test this myself, since I don't have Yos. Is what you are saying documented somewhere?

Replacing Mac Mini Hard Drive with SSD, and New ML Install

I have a mid-2011 Mac Mini, and it has been running very sluggish, even when there are multiple free GB of RAM and the processor is only at 10 to 20% of capacity. I ran TechTool Pro 6 to do a scan of the whole machine, and it didn't detect anything out of the ordinary.
At this point I am guessing that it's probably a software issue. I have tons of processes running in the background all the time, and have installed hundreds of programs over the last two years, so it could be anything number of things that are somehow messing up Mountain Lion.
So, I would like to replace the 500GB internal hard drive with a 120GB SSD Drive (Samsung 840 Series), and put a fresh install of Mountain Lion on the SSD, put the 500GB in an external enclosure, and see if that fixes the problem.
Can someone explain the best way for me to do this, in a step by step list?
I can figure out how to accomplish each step, I just need some overall guidance as to how I should approach the whole thing.
Thanks very much!
Some other notes:
I have a 3 TB hard drive that I can use to back up everything on the 500 GB hard drive, but I'm assuming that time machine isn't the best way to back everything up, since I won't be able to restore the machine on the 120GB drive that I want to boot from.
Normally, I would get the internal 500GB down to 100GB of data, and then clone it on the SSD, and make the swap, but I'm assuming that cloning the drive will potentially replicate the source of the slowness, so I'm assuming that isn't the best way to proceed.

Here is my opinion and steps I would perform.
Back up your system first.
Check the iFixit.com site for a guide of how to replace the drive. Review Steps 3 and 4 BEFORE you replace your drive.
If you have a USB thumb drive with the ML 10.8.3 installer, skip to step 6.
If you don't have a USB thumb drive with the ML 10.8.3 installer, download the OS X Recovery Disk Assistant and use a 1-4GB thumb drive to create a Recovery HD on the thumb drive you can boot from. Skip to step 6.
If you have neither of the above, after replacing the drive, restart into Internet Recovery by pressing/holding the Command+Option+R keys. Since you have a mid-2011, Internet Recovery will ONLY allow you to download and install Lion since that's what probably came preinstalled on your system.
After you replace your drive and you are booted into the OS X Utilities Menu from one of Steps 3-5, select Disk Utility and format your new drive as Mac OS Extended-Journaled with the GUID partition table.
Go back to the OS X Utilities Menu and select Reinstall Mac OS X.
After the download and install of OS X you can run through the setup creating your user account (same as you had on you old drive).
If you were able to install OS X ML, skip to step 11.
If you installed Lion, you will have to login to the App Store and download/install your purchase of ML.
Run Software Updates to bring your OS X up to date.
Now you can restore any data files and apps that will fit onto the new drive from Time Machine. Enter Time Machine and navigate to your last backup to view the /Applications folders and your user folders (e.g Documents, Downloads, Music, etc.).
For your email, you can open Finder then press the Option key to see your user Library folder in the list. Select it to open it then enter Time Machine again and navigate to your last backup so that your user Library folder is opened in Time Machine. Copy your Mail folder to your Desktop so you can copy it back to your current user Library.
I think that's it.
