Firewire and OWC Drives

I just purchased 2 1TB OWC firewire drives and have daisy chained them to my MiniStack V2 (firewire port) connected to my Mac Mini. I have had a series of issues which I will explain below. I should note that the OWC drives are not alike. One is a Seagate with an Oxford 934 Quad interface, and the other is a Hitachi with an Oxford 934 FW 400 / USB2 only.
1) When I have the Mac set to put the hard drive to sleep when possible (runs quieter), the Hitachi doe s not always seem to wake, resulting in the system hanging. The only fix is to disconnect the firewird going to the OWC/Hitachi drive.
2) When the Mac is not set to sleep harddrives, things seemed OK until (a) my Quicken 07 crashed (files are on MiniStack); (b) Software Update failed; (c) finder would not relaunch. Again, things corrected themselves when the firewire cable to the OWC drives was disconnected.
Any ideas what might be going on?

I had problems with OWC drives in the past. Especially the ones with the Oxford 911 chip. I first hooked the drive via FW to the Ministack and then with usb 2.0 I tried using a Belkin powered Hub. The problem I was having was the drive wouldn't finish a burn either cd or dvd.
What I found out by trial and error, I had to hook the drive to the main computer FW or USB port for it to work properly. Then I remembered what a friend told me about daisy chaining. If you have a burner in the chain,it must be hooked first to the main computer and then hook other stuff afterward. Since I only have one FW port on the Mini, I hooked the Burner Via USB and my Ministack Via FW.
I hope this helps.

Adding FireWire and USB drives

Want to add a FireWire hd and a USB floppy drive to my Mac Pro.
Should I use a powered hub?
I've heard of powered hubs blowing the Mac input ports.
Already have the USB floppy drive. It's power consumption is listed as 2.5 watts.
Any reccommendations on powered hub?
Any reccommendations on a FireWire hd?

I don't use hubs. You can get a FW800 or combo FW800 w/ USB2 from OWC and sold by Aaxeon for $109-124.
I have over half a dozen FW800 drives. All direct connect (only use 4 at a time obviously). And never mix consumer electronics w/ FW hard drives on the same bus, or at least sharing a hub or uplink.
Lot of good FW cases http://www.macsales.com
They also have Quad interface SATA-FW800-USB2 if you need that.
FW - definitely stay with Oxford 911+ for 400, 912 for FW800, or 924 for Quad interface. I am not a fan of dual drive case with "firmware RAID" which use Oxford 922 chip in the FireWire bridge. And it is the bridge chip that makes all the difference.

Firewire and external drive

I bought an additional hard drive. I daisy chained it to existing external hard drive which is connect to my mac via firewire. My mac now doesn't see either drive. If I plug original external to USB my mac finds. How can I get my mac to find my external drive again via firewire? Thanks.

If your FireWire drive is one that has USB and FireWire interfaces, you can't connect another drive on a different type of bus than the one used to connect to the host computer. If I'm reading what you're saying, it sounds like the new drive is USB and you're trying to daisy-chain that with the FW drive. Not going to work.

Firewire and ejecting drives

I have a new prodrive 1 TB by sinpletech connected via FW 800 to my MBP 2.5 GHz with 4 GB RAM. When I eject the drive and turn the drive off....I do not necessarily need every hour back ups, the drive will not mount if I turn it back on. not even after a restart of the MBP. I actually have to un-connect the FW 800 cable and restart the MBP and then reconnect for it to mount.
I also have a USB hub plugged in with my mouse and speakers connected.
This never happened with my iMac.
Do you think it is the drive or the MBP?

Tried the drive out on my iMac and all is great. I tested a few things on the MBP. Here is the scenario when it has issues:
MBP up and running
eject the external FW 800 HDD
turn the HDD off
Close lid on the MBP
MBP sleeps
Wake the MBP
turn back on the FW 800 HDD
nothing mounts
nothing in disc utility
Have to unconnect all cables and restart the MBP and then plug in and turn on the HDD for it to mount
When just ejecting the HDD without turning it off and sleeping the MBP, it comes back on just fine.
I also tried to do a hardware test with the install DVD in and pressing D when the MBP restarts...I get the message that Hardware Test does not support this machine...???

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.

Can i back up one G5 via firewire and another via USB to the same drive

I have an ibook and a G5., I have a 500 gb lacie external drive.
Can i back up both via time machine simultaneously, one via firewire and one via USB?

No, you can not directly attach one drive to two computers at the same time, period. In particular, you can't use it for Time machine this way.

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.

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...

My firewire drive isn't mounting. The port is fine and the drive powers up and spins. Help anyone?

Hi, thanks in advance. My firewire drive isn't mounting. I have used this firewire drive for a few years and it has never had any problems at all. The port appears in the System Profiler and the drive is working fine. Do I need to update my firmware or something? I haven't dropped my drive or experienced any weird physical issues with either the firewire port or the drive (ie shocks from static, getting kicked accidentally, etc).
Do you have any thoughts on how I can fix this issue? Its very critical, I have several client projects on this drive and will be SCREWED and out of a job soon if I can't get this situation solved. THANK YOU!!!

Another interesting issue, is that when the firewire (800) drive is connected, the system takes forever to boot (about 4 minutes). Without the firewire drive connected, it boots up automatically.
I suspect the long boot times is because the boot process is trying hard to get the disk checked and mounted which of doesn't happen when it is not connected.
Disk Utility doesn't see the drive at all.
Well that isn't good. This disk may be (physically) damaged beyond repair or the format so corrupt that even DU doesn't know what to do with it. But on the subject of firmware, you shouldn't need that for FW400/800 connections but what kind of enclosure are you using? If there is a firmware update at all it would be from the maker of that enclosure for that enclosure.
Is it possible to remove the drive from the enclosure and put it into your mac pro?

Firewire for interface and hard drive

I have a firewire Lacie external hard drive and m-audio 410 firewire interface, does using firewire for both affect the overall performance in logic express, or firewire and usb is better?

Hi John,
I use usb and firewire just because my audio interface doesn't have firewire.
Also, has been using booth firewire ports on my PowerBook, with the Lacie on one and a camera on the other importing video, and had no problems.
So, I think you're ok, you have a G5, Firewire's faster, you really shoudn't have reasons to worry. Give it a go!
regards,
Jorge

Journaling External FireWire and USB 2.0 Hard Drives?

I have several FireWire and USB 2.0 Hard Drives which I have always formatted as "Mac OS Extended (Journaled)".
I have been told that journaling is a waste of time with external HDs and, if anything, will slow them down slightly.
What is the general consensus on this forum?

Thank you for the swift response Malcolm.
I better explain why after all these years I am having doubts.
I am awaiting the delivery of a new piece of kit - a Western Digital HD TV Media player. Basically, you put your hi-def videos (H.264) on a USB 2.0 HD, plug it into the media player which is then plugged into your HDTV.
I have got hold of the manual which says that the supported USB file systems are "FAT32, NTFS and HFS+ (no journaling).
So I was wondering whether I will have to format the HD without Journaling to make it work?

Hard Drive Speed Difference Between FireWire 800 and Internal Drive

Right now I have my entire 1.5 TB Lightroom photo library on an external drive connected to my new Mac Pro via FireWire 800. Will I experience dramatic or even noticeable speed improvements if I move this drive to one of the internal SATA hard drive bays in my Mac Pro?
I would likely buy a new drive and SuperDuper the external to this new drive I put in the Mac Pro.
Thanks,
Matt

SATA II 3Gb is only the controller bus and has almost nothing to do with actual individual drive speed. Confusing the bus interface with hard drive speeds is not a clear way to compare.
Just pull the drive out of the FW case is all you probably need to do. Actual FW800 is less than 80MB/sec and more like 72-75MB/sec - which is as slow as your hdd gets from slow inner tracks.
Other than green, most 1.5TB drives average minimum 75MB/sec to max 115 with average in mid-90s. And the first 1/2 of a drive is where best performance comes from.
The size of the data and media library, amont of free space, all play a role.
I think FW should be left to backups, an alternate boot volume, off line data.
If it was Aperture library, but otherwise SSD is not realistic or viable. Nobody uses RAM disks as they are inefficient.
I still find 10K VelociRaptor ($279 / 600GB) fast, smoother, more responsive, great for system and data drives, even if they are only 135MB/sec, or about what some of your 2TB drives can offer.
QUICK TAKES - A striped pair of Velociraptor 600G 10K HDDs matches the speed of one SSD. For less that the price of one 256G SSD, you can buy two 10K 600G Velociraptor HDDs. If you stripe them (RAID 0), you get the same sustained transfer speed as the SSD. http://www.barefeats.com/quick.html
If you are not already using all the internal drive bays, just nice to have them handy before going external. Also take a look at two other articles on Barefeats:

Daisy Chaining Firewire And Thunderbolt

I have a 2009 iMac and a couple of G Tech external drives linked via Firewire 800. Runs FCPX okay if slow on "export/share". I'm about to buy a MBP retina 13 inch, I need the portability, but wish to keep using the iMac as the main editing machine.
I'd use an external drive with the Retina, Thunderbolt/USB 3.0 seems the optimum choice. My question concerns using "material" stored on the Tbolt/USB external drive for use with FCPX on the iMac via the G Tech Firewire external drive.
Can I simply connect the iMac to the GTech drive via the single Firewire port, and connect the Tbolt/USB to the Gtech drive via the Apple Thunderbolt to Firewire adapter, and thus transfer files (or even FCPX projects) from the new drive to the old drive?
Ron

Yes. Depending on the drive enclosure you may need to power the TBolt drive as it may no longer be bus-powered. My LaCie Rugged drives are bus-powered through the adapter cable. My OWC drives are not.

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

IMovie and Firelight drives

I am wanting to do some home video stuff using iMovie 4 and possibly final cut pro 3.0 on a PB 17" / 1.5 ghz / 10.3.9 / 1gb ram.
I need an external drive to store the video data and am wondering if the Firelight drive is suitable for use in video editing.
Thanks in advance for any replies

It's good that you're looking ahead and considering an external drive, as video editing takes alot of disk space, both for editing and storage.
You can use an external hard drive with a firewire connection, which is preferred over a USB-only connection. If you want to maximize the speed, you'll use an external drive which supports the faster FireWire 800 (IEEE 1394b) port your system has.
You might consider building your own. Sounds daunting, but it's really very easy. The benefit is that you can use a hard drive with a 3 or 5 year warranty, unlike most complete units that only have a 1 year warranty.
It's really as easy as this: Buy the drive you want (I'm currently using a 3.5" Western Digital 320gb drive). Generally I've found the Western Digital drives run cooler than others. Buy the case you want (the oxford chip set works well in my case), take the cover off the case, insert the wide plug from the electronics in the case to the hard drive, insert the power plug in the case to the hard drive, attach 4 screws to hold the hard drive in the case, reinstall the cover, done!
In the US, Newegg at http://www.newegg.com and OWC at http://www.macsales.com both have good selections of hard drives and cases.
