Firewire 800 Hard drives - RAC

Can RAC be installed with RHAS2.1 using the new firewire 800 hard drives?
Is a specific firewire chipset required?
Thanks,
Javier.

I have heard people say good things about the Oxford 911 firewire chipset, but your mileage may vary.
I personally went out an purchased an ADS Technology PYRO 1394 Drive Kit (http://www.adstech.com/products/PYRO1394DriveKit/intro/API800intro.asp?pid=API-800) which uses the Oxford 911 chipset. I then installed a Maxtor 40Gb IDE hard disk.
I have configured ocfs to use this PYRO 1394 Drive Kit which is attached to my two Red Hat 2.1AS servers. I still have to install Oracle and condifure a db.
Hope this helps,
Daniel

I have a Power Mac G4 (2004) and want to transfer all my files to a new MacBook Pro 15.4". Can this be done thru firewire cable or do I have to transfer to an external Firewire 800 hard drive first?

I have a Power Mac G4 (2004) and want to transfer all my files to a new MacBook Pro 15.4". Can this be done thru firewire cable or do I have to transfer to an external Firewire 800 hard drive first?

Do it with a Firewire cable (buy a 800/400 adapter if you need it) - the USB transfer takes a much longer time.
Start up your old PowerMac G4 holding down the "T" key, for target disk mode.
On your new MacBook Pro open "Migration Assistant" in your utilities folder.
Connect the 2 computers by firewire cable and follow the prompts in Migration Assistant.

Will a Firewire 800 hard drive work on my MacBook with Firewire 400?

Hi, I have a MacBook I bought in 2008. The FireWire specs say " Maximum Speed: Up to 400 Mb/sec"
I am considering a new external hard drive (the Iomega MiniMax) and want to use Firewire for this one. The specs for the hard drive say: "The MiniMax includes 2 fast FireWire 800 interfaces, a USB 2.0 hub, plus a FireWire 400 to 800 cable."
Will this FireWire 400 to 800 cable allow me to plug my FireWire 400 laptop port to this FireWire 800 harddrive port? It sounds like it will but I wanted a sanity check before I order it.
Thanks.

Yes, that should work just fine.

My LaCie Firewire 800 hard drive, connected to my Macbook Pro via Thunderbolt Cinema Display port, disconnects after sleep

I have a LaCie RAID Quadra hard drive (two disks in a case set to a redundant array) which for all intents and purporses appears as a normal hard drive to my mac.
When connected directly via FW800 to my Macbook Pro (2011, with thunderbolt port), it works perfectly.
For the sake of convenience, and since I am using it only at home as my Time Machine drive, I connected it to the FW800 port on my Thunderbolt Cinema Display. The display works perfectly in every way up until now.
When connected, the drive works great. However, when I put the machine to sleep, upon awakening it, I receive the "Disk improperly ejected" error immediately upon the screen coming up.
The drive is set to Auto mode which has always worked fine in the past; putting the drive to sleep when the computer is asleep, etc.
So, I only receive the disk ejected error when it's plugged into the Cinema Display; not when directly plugged into the MBP.
I have the 1.1 firmware update applied to the monitor.
Any ideas? I appreciate it.

My desktop has two FireWire ports. In the first one I had my webcam plugged in. In the second one, the External Hard Drive. I unplugged the camera and used the first port for my External HDrive and now it works! So it seems the problem is a hardware problem with the port.
I'd check to see if the problem returns when you plug the camera back into the second port, or if the drive works in the original port when the camera is not connected.
Edit: Maybe you unplugged the problem, when you unplugged the camera?

My MacBook Pro hard drive is almost full and I wish to store my Aperture Library on an external drive, how do I do this and is the use of USB2 suitable or do I need to use a Firewire external hard drive?

My MacBook Pro hard drive is almost full and I wish to store my Aperture Library on an external drive, how do I do this and is the use of USB2 suitable or do I need to use a Firewire external hard drive?

You'll get better performance if you use a Firewire hard drive (especially if you buy a 7200 RPM drive). Firewire's IO speed is significantly faster than USB 2. USB 2 has a theoretical max speed of 480 Mbps except that it has extremely high over-head. The fastest speeds you can typically get are about 300 Mbps. Firewire, on the other hand, has very little overhead. The fastest speeds you can get are very nearly 800 Mbps. You will typically be constrained by the maximum read/write speed of the drive, not the speed of the I/O on the Firewire bus. Now if you had one of those nice shiny new Macs with the Thunderbolt I/O and a Thunderbolt drive (Light Peak) ... I think they alter space and time so that your data arrives before you know you want it.
Also... unless you want to buy a solid state drive (very expensive), try to keep your hard drives from becoming much more than about 60% full if you want great performance. A nearly "full" hard drive is, on average, only about half as fast as the same hard drive when nearly empty.
USB 2 will work perfectly fine... just not as fast.
Also... it's much safer to move the entire Aperture library than to "relocate masters". Your images must be managed. You can Aperture manage them, or you can manage them. But someone has to manage them. If you "relocate" them so that they are no longer stored inside the Aperture library then you'll need to work out a system of how you decide to organize things and it's critically important that you don't start moving files around or deleting things without Aperture's knowledge. If you do, you'll break the links to your masters and start having problems with missing masters. If you have Aperture manage the library then you don't need to worry about any of that stuff.... it's safer.
Do make backups (use the Aperture Vault or use some other backup program, but make sure you back up your work if you care about it.) There are only two kinds of hard drives in the world: (1) those that have failed and (2) those that are going to fail. There are no exceptions to this rule. Hard drives are cheap. Backup software is built into Aperture and into your Mac.

I need a firewire-800 external drive tower

I currently have several external hard drives each individually connected via FireWire 800, all drives chained together via the FireWire 800 in-out connectors.
What I really need is a 4 or 5 bay hard drive external tower of some kind to reduce desktop clutter. And a tower that has FireWire 800.
I've found several 4 bay storage towers but that all are for RAID usage.
I don't need RAID. I'm not even sure if I could disable the RAID part, and just use the tower simply as external storage/expansion (which is what I want)?
I've read some of the user manuals on these RAID towers, and it seems the units are meant for RAID use only.
I don't know much about RAID, except that it mirrors one drive onto another as a safety backup.
Does anyone know where I can get an external 4 or 5 bay tower with FireWire-800 for extra storage only? No RAID needed.
Or... can the RAID towers just be used as external storage?
If so, how might the RAID feature be disabled? Or can it?

I'd recommend you call OWC http://eshop.macsales.com

External Firewire 800 hard disk kills internet connection

Hi,
I am having the following problem:
1. Plug Seagate FreeAgent GoFlex 1TB drive into Macbook Pro via Firewire 800
2. Internet connection dies. By "dies", I mean I disconnect from the wifi network. The degree of death varies from complete lack of visibility of the wifi network, to visibility but cannot connect ("connection timeout" when entering the password (which I should not have to enter anyway, as it's cached in my keychain)), to connection but no IP address given by the router via DHCP, to sometimes getting an IP but being unable to ping any other IP address on the network apart from my own.
3. Ejecting then disconnecting the drive physically, fixes the problem.
4. Connecting the drive via USB instead of FW800, does not reproduce the problem.
5. Connecting any my 500GB Lacie rugged drive via FW800 does not produce the problem.
Like the guy in this discussion (http://discussions.apple.com/message/15615649#15615649), this is only happening with my Seagate FreeAgent GoFlex 1TB drive and only when I connect it via Firewire800. With any other drive, OR if I connect the Seagate via USB, all is OK. Note that I'm re-posting this discussion because that other guy accidentally marked the problem as "fixed", but it was never solved.

When the firewire card is not connected, I get the following screen in system profiler:
FireWire Bus: powerbook's built-in FireWire bus

Mount Point: /Volumes/250 Gb
Notice that the connection speed of the hard disk is 400Mb/s in the first, and 800Mb/s in the second.
The reason I'm fussing about this is because I'm using the hard drive with Pro tools, which officially supports Firewire 800 hard disks with the Oxford 912 chipset (which is what this one's got). And I've had a lot of problems bouncing to disk, even with just a stereo mix (96KHz 24 bit) Where Pro Tools (M-Powered) says that it can't read data from the hard disk fast enough!
I just want the hard disk to run at 800Mb/s and the audio interface to run at 400. Am I asking too much?
Someone must know how to do it.
Thanks for your help!

Editing using a firewire external hard drive and a NTSC television monitor

I have Final Cut Express 2 and use it with a firewire external hard drive and a NTSC television monitor.
I have started to use iMovie with this same set up. I save my iMovie projects to an external hard drive and also have my miniDV deck connected via firewire with the composite outputs going into a 27 inch television so that I can get a better idea of what my colors and title safe framing, etc. look like.
I have had some minor problems with this set up. Like stuttering video, audio tracks playing back when thay are "unchecked" and the "unexpectedly quit" deal.
Thanks in advance!!!
Frank

iM uses a lot of harddrive space on the "start up"/internal disk, even when the project itself is located on some external drive.. make sure, you have at last 10 - 15GB free...

FireWire external hard-drive

Hi, I bought an external hard drive from Welland. It does USB 2.0 and Firewire 400. When I hook-up the drive to my mac mini, everyting is fine, it's work perfectly. But if I don't use it for a day or 2, the drive goes on sleep and when I try to access data on it, it's jam. The front light start to flash and I need to turn off and on. Then it's work. I try to remove the option to put the drives on sleep when possible but no better results

Have you contacted Welland for some support? It's possible the drive is not functioning correctly. I have several FireWire 400 hard drives at home and the one plugged into my G4 Cube goes to sleep quite often without an issue like that when I wake it up. Is the drive powered by USB and/or FireWire?

New Firewire external hard drive freezes

I have an external USB hard drive, and it works fine if I test it by copying and pasting 10 .jpg files (total ~ 2Meg) to the external USB hard drive from the internal hard drive. I got a new external firewire hard drive and if I try the same test, it freezes mid-copy. (It just sits there forever and I actually have to power down to get it to un-freeze).
It's a brand new Acomdata 250GB firewire external hard drive.
What could be wrong?
Thanks!

Welcome to Apple Discussions!
I'd return the drive. Get a drive from
Otherworld Computing
Granite Digital (they make cases to go around internal drives)
LaCie
Cooldrives
These are the only ones I know to reliably work under Mac OS X 10.3 or higher.

FireWire External Hard Drive Workaround

Scenario:
1.) AirPort Extreme connected to Mac Mini via ethernet.
2.) Mac Mini connected to a FireWire External Hard Drive.
3.) MacBook Pro connected to AirPort Extreme via 802.11n (wireless).
4.) AirPort Utility is administered from the MacBook Pro.
Problem:
Considering that the AirPort Extreme does not support a FireWire External Hard Drive, I was hoping to find a work around. Is there any way to indirectly access the FireWire External Hard Drive connected to my Mac Mini from my AirPort Utility administered from my MacBook Pro? Essentially I want to access files from the External Hard Drive on my MacBook Pro without being physically tethered to my Mac Mini or the External Hard Drive. That is, I would like to define the External Hard Drive as an Airport Disk in Airport Utility so I can utilize the Back To My Mac feature.
Solution:
Your solution goes here...

That is, I would like to define the External Hard Drive as an Airport Disk in Airport Utility so I can utilize the Back To My Mac feature.
No that won't work.
If your Mac mini simply has File Sharing enabled you can get to the drive using Back To My Mac with no involvement of the AirPort Extreme base station (AEBS).

Firewire external hard drives no longer mount

I had 2 firewire external hard drives connected, not always at the same time and not running all the time. Suddenly they won't mount. I have run System Profiler and it shows "No information Found". The drives themselves mount on my other Mac laptop.
An external DVD writer, when mounted, shows up in profiler though not on the desktop. I have set the finder preferences to -show all mounted drives. System profiler lists all my USB devices. It's just the 2 Firewire hard drives that show no information found. The DVD writer works in either Firewire port.The hard drives are each made by a different manufacturer.
I have re-started with everything off. I have hot swapped.
Help-I need these drives to store photo files and print publications.

fairview:
The next step is to see if it is directory related and Repair Disk:
Insert Installer disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu (Panther and earlier) or Utilities menu (Tiger) and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
(Check S.M.A.R.T Status of HDD at the bottom of right panel, and report if it says anything but Verified)
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
If DU reports errors it cannot repair you will need to use a utility like Tech Tool Pro or Disk Warrior
Good luck.

Ongoing troubles with firewire Lacie hard drive

A couple of years ago I purchased a Lacie firewire 160GB hard drive to use as a backup for my aging G3. After encountering problems formatting and mounting the drive I put it aside to concentrate on my work. Recently I powered up and connected to my G3, and the drive mounnted on my desktop. I proceeded to copy files over [my internal 9 GB drive was nearly full]. Just as I finished the Firewire drive crashed and I may have lost several years of work unless I can retireve the data and maybe replace the drive. Maybe the drive would function correctly if used with a G4 or G5 but for the moment I use what I have.
Does anyone have any idea what may be the problem and how I might repair the drive?

I agree with what Bill W says
if the drive is acting flakey, its hard to say whether it is the drive or the bridgeboard in the enclosure
first thing to do is to update the firmware on the bridgeboard in the enclosure - you can find firmware tools here: FireWire firmware/tools
if that doesnt work, then you should take the drive and place it in a new enclosure such as the following: FireWire Enclosures
the problem is, in either case, if the problem is the drive itself, then before doing anything is to run a data recovery app on the drive to get any data you need to recover/save - the most popular is Prosoft Engineerings Data Rescue

Are (some) external firewire 400 hard drives just cased sata drives?

Are (some) external firewire 400 hard drives just cased sata drives? If so, I think I'd like to bust open my external 160GB Lacie and mount it internally...
I have no idea if they are or not, it just crossed my mind at one point.

Possible but unlikely. PATA drive remain less expensive in bulk and PATA ->FW enclosures are more mature and wide spread than SATA->FW. Larger drive cap. drives are more likely to be SATA.

Firewire 800 external drive no longer mounting

My firewire 800 external hard drive is no longer mounting on my MBP. It powers up, spins, but has no reaction to being plugged into my computer. I've tried connecting it and the turning it on, and connecting it while it was already turned on. I've tried different cables and different types of adapter cables (fw800 to 400, fw800 to USB, etc.), but there is no communication between my drive and my Mac. Same goes if I connect it to my wife's Macbook, or my iMac at work.
I recently had the logic board and left i/o board replaced on my MBP, I'm not sure if this is relevant since the drive has worked since the replacements and I get the same results on other Macs.
What should I do next?

who makes the drive set up?
OWC for example has a history of bad power supplies that make the drive not accessible (drive spins up but never spins all the way up)
