Can't get Mac Pro to recognize OWC Mercury Elite Al-Pro QX2 Raid on eSata
Hi Everyone,
I have a new OWC Mercury Elite Al-Pro QX2 Raid, set up as Raid 5, w 4 x 2TB Hitachi drives. I have been able to get it to mount on my Mac Pro via FireWire connection only, can't get it to mount via eSATA.
Since the purpose is video editing, I need the eSATA connection to work.
Any ideas on how to get the Mac Pro to see the eSATA?
I've tried switching eSATA cables to one that has been verified to work, still no luck.
Thanks!

Dear Sunshine22,
The QX2 uses an Oxford 936QS chip that can require up to 45 seconds to startup all of the hard disks and become ready to accept eSATA controller commands. Usually, the QX2 enclosure will beep when it is finally ready.
The amount of time required to startup the enclosure can be longer than some eSATA drivers expect. There are two possible options you might try to get around this issue.
1. Unplug the QX2 eSATA cable from the controller. Turn on the enclosure and wait 45 seconds or until the enclosure beeps indicating it is ready. Next, connect the eSATA cable and the enclosure should show up in Disk Utility within the next 20 - 30 seconds.
OR
2. Turn on the QX2 and wait for 45 seconds or until the enclosure beeps. Now restart the Mac Pro and the enclosure should mount on the desktop or show up in Disk Utility.
Perhaps one of these methods will mount the QX2 for you.
FirmTek has updated our eSATA drivers so that these work arounds are not usually necessary when an Oxford 936QS based enclosure is attached to a FirmTek PCIe controller.
Good luck!

Editting PDF documents that were created by a MAC doesn't work because of font incompatability. How can we get MAC fonts and load in our Adobe Acrobat Pro 9?
If it's a Mac font and you're on Windows, you can't. If you are also on a Mac, you'll need to purchase the fonts (fonts are generally non-transferable, like software. One of the reasons pdf exists), install them and try your edits.
But it's best to edit the original document and create a new pdf when finished. -
My iMac suddenly can't read the backup hard drive I've been using for Time Machine. I tried unplugging the cord that connects the HD to the iMac and plugging it back in, but I still get "The disk you inserted was not readable by this computer" below which are buttons for Initialize, Ignore and Eject. I was using a cord that went from larger square plug to larger square plug. So then I tried one that went from smaller square plug to what I think is USB (thin rectangular plug) of the sort that connects the keyboard and mouse. It's the type that my printers and scanners use to connect to the iMac. I did NOT just upgrade the OS or anything. The external HD is an OWC Mercury Elite All Pro. It's worked fine since I got the iMac 4 years ago. What else can I try before just trying to initialize and
Thanks, Michael! I do hear it at times spooling up and running. Just after I bumped the thread I looked for troubleshooting for this drive online and found the manual which suggested using Disk Utility which I've seen before accidentally (if I hit Command Shift U instead of Shift U to type "Unit" on a new folder for a student's homework ) but had never really noticed. Disk Utility does see it and also a sub-something (directory?) which might be the Time Machine archives on the disk, called disk1s2), sort of the way that my iMac's hard drive shows up as 640.14 GB Nitachi HDT7... and has a sub-something titled DB iMac, which is what I named my iMac's hard drive.
Anyway the owner's manual just shows the image under the formatting section, not the troubleshooting section, but as soon as I saw it in the manual I remembered seeing it accidentally a few times, went to it, and am now verifying the disk. Right now it's telling me that it will take 2 hours to complete the verification, so I guess I have a bigt of a wait. :-)
Does that fact that Disk Utilities can see it mean it's not failed, or just that it hasn't completely failed?
I can see the virtue in having multiple redundant backups, or at least two backups. What do you suggest? Two external hard drives? I had this one linked by ethernet, and but I also have a cord that could link it by USB (like a printer), so if this one is reparable I could get a second one and link it by USB. If this one is not reparable I could get two and do the same thing. I do have an Airport so I suppose it's possible to get some sort of Wi-Fi hard drive (my new printer/scanner uses only the network and not a cable, although it has a cable that I used for the initial installation), but I'd suspect a Wi-Fi hard drive might have a higher price.
What hard drives, if any, do you recommend? I seem to recall that when I was looking at external hard drives 4 years ago, Apple's were substantially more expensive, which is why I got the OWC Mercury Elite All Pro. -

Connecting OWC Mercury Elite-AL Pro Dual-Bay (RAID) Enclosure help setup
System info:
Enclosure: OWC Mercury Elite-Pro Dual Bay (RAID Enclosure)
Comps: Mac Pro & MacBook Pro 13"
OS: 10.6.4
Connected enclosure via firewire800 with 2x 2tb hitachi drives.
So I picked up an Open Box version of essentially this enclosure:
http://eshop.macsales.com/item/Other%20World%20Computing/MEFW936AL2/
(the differences is, the light is not in the direct center of the enclosure as pictured and the little blue switch is not on the logicboard under the fan like it was pictured in the instructional booklet).
Now going through the instructional manual, and wanting to set it up as a RAID 0 i noticed that on my enclosure there wasnt a place on the board for it to switch it to proper type of configuration i wanted.
And their site is a little messy (imho) to find the proper info and so many variants of their enclosures.
So heres what my enclosure board looks like:
http://img842.imageshack.us/img842/7708/owc.jpg
I put two 2TB drives in the enclosure (2 Hitachi Deskstar 7200s).
plug it in via FireWire800 to my MacBookPro and get the initialize the drive alert and thats where iam at. I havent set up this particular enclosure before so im not sure if its all software controlled now and the best way to go about configuring it the way I want it to (RAID 0 for now).
and how to go about in the future changing it if i say wanted RAID 1 or JBOD.
any help would be greatly appreciated!
Thank you!thanks, though the problem has been resolved courtesy of Loudspeakermusic's link.
The problem is that the manual doesnt state anything about this particular drive.
As you can see from the image:
mine does not have the actual jumper settings like indicated of Page 5 of the PDF Manual (the same Manual i got with the actual enclosure).
So the firmwire utility helped as I was able to create the RAID or RAID 1 or SPAN/JBOD properly.
According to OWC if there drive was over 1TB in size I must click on the Enable Large Disk box to allow me to use 2x2TB drives then once I set the firmware to RAID 0, i can format them properly in Disk Utility.
So far I'm running the 2x2TB (4TB) in RAID 0 on my enclosure fine and can transfer just well.
Like Loudspeaker stated, i have to have the drive directly connected and not daisychained as I did not know why I wasnt able to change the firmware settings.
as shown:
Thanks for all the pointers! -
Audio dedicated HD: LaCie d2 Quadra, WD My Book Studio or OWC Mercury Elite
Hi, I'm choosing between the LaCie d2 Quadra, WD My Book Studio and OWC Mercury Elite-AL Pro, pretty similar, looks like the only difference is the Lacie has 16MB cache, the WD is unspecified and OWC has 32MB... which had me leaning towards OWC's.
The lowest prices I've found are $150, $140 and $170+shipping (their website only) respectively. So although I was convinced about the OWC it is the most expensive one.
1TB using FW800 BTWTheis PSUs die.
I had forgotten about my incident, I just avoid to buy their drives; but the other day I went to a "Mac service" and saw no less than 10 of them all broken. I asked and all were PSU fails.
Not BIG deal, but when you open it to save your data because otherwise you´ll have to ship it and pray you loose the guarantee. I´ll have to read A LOT of good things from Lacie to change my mind. They charge you for an enclosure and the enclosure fails... BIG DEAL
Just my experience and opinion. Maybe you buy one and you LOVE it. -

Can't get MAC to shut down and start up via the schedule button in system preferences energy saver. Is there another way?
Try this to start:
Repair the Hard Drive and Permissions
Boot from your Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X. -

I need to how can I have Mac OS Lion, as I bought my Macbook Pro in beginning of June 2011 from Apple Store in US.
The serial number of my product is C0*******H2M. Please confirm me that I can have it for free, and how could I install it. Many Thanks.
<Edited by Host>Sorry, but that opportunity has long passed. Your options now are:
Upgrading to Lion
If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service - this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
Lion System Requirements
1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
or Xeon processor
2. 2GB of memory
3. OS X v10.6.6 or later (v10.6.8 recommended)
4. 7GB of available space
5. Some features require an Apple ID; terms apply.
Upgrading to Mountain Lion
To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
OS X Mountain Lion - System Requirements
Macs that can be upgraded to OS X Mountain Lion
1. iMac (Mid 2007 or newer)
2. MacBook (Late 2008 Aluminum, or Early 2009 or newer)
3. MacBook Pro (Mid/Late 2007 or newer)
4. MacBook Air (Late 2008 or newer)
5. Mac mini (Early 2009 or newer)
6. Mac Pro (Early 2008 or newer)
7. Xserve (Early 2009)
Are my applications compatible?
See App Compatibility Table - RoaringApps - App compatibility and feature support for OS X & iOS.
Am I eligible for the free upgrade?
See Apple - Free OS X Mountain Lion upgrade Program.
For a complete How-To introduction from Apple see Apple - Upgrade your Mac to OS X Mountain Lion. -

How can i get in work my Hp scaner with my macbook pro?
how can i get in use my Hp scaner with my macbook pro?
You have the display set in Extended Desktop mode with the MacBook as the main screen. The Menu Bar and Dock will be on the MacBook display and your background screen on the TV but you can move the cursor onto the TV screen.
In System Preferences>Display on the MacBook screen there should be an Arrangement tab when you have the MacBook hooked up to the TV and both screens working. When you click the Arrangement tab do you see two monitors side by side? One of them will have a Menu Bar at the top. Just click on the Menu Bar and drag it to the second monitor. That will make the second monitor your main screen.
The TV will now have the Dock and Menu Bar and windows will open on it. But you can move the cursor to the MacBook screen and move windows from the TV over to the MacBook screen.
You can now use your MacBook in Clamshell Mode with a wired or Bluetooth keyboard and mouse. http://support.apple.com/kb/HT3131 When you disconnect from the TV your Menu Bar will automatically change back to the MacBook.
Or if you want to work on the MacBook screen while showing it on a TV you can check the Mirror Display box on the lower left hand side of the Arrangement tab under the two monitors box. That will give you the same screen at the same resolution on both the MacBook and the external monitor. -
How can I get Mac mail to open winmail.dat attachments on lion 10.7.3
How can I get Mac mail to open letter attachments winmail.dat?? (Lion 10.7.3) Any help appreciated...
Sorry peterskine,
it's true in part. There's more then one article on the subject "Recipients receive a winmail.dat attachment":
http://office.microsoft.com/en-gb/outlook-help/recipients-receive-a-winmail-dat- attachment-HA010153018.aspx?CTT=1
The odd thing is that my colleague and me use the same release mountain lion and we received the same email from someone on Outlook2007. He received the mail with the attachment, whilst I saw a "Winmail.dat". It already happened to me on snow-leopard, some month ago. Up til today I don't know what the difference between our machines is.
But it is interesting: the same OS, the same mail-clients (Apple Mail) and still different results.
Note: on my machine it used to work properly. It just suddenly happened that I started to receive winmail.dat files in stead of proper attachments.
When I have more time on hand, I cant try to find out why this happens.
