Hardware :: Daisy Chaining FW400 Drive To FW800 Drive
Dec 7, 2009
I may soon buy one of the newer generation iMacs that drop the FW400, includes 800 only. On my current Mac, I have a FW800 drive and a FW 400 drive. I use the 400 for time machine as speed is less important. My current iMac has a 400 & 800 connector. I have tested connecting the 400 to the 800 drive via daisy chaining, so everything is pulling off the 800 connector, so this assures me I can do this with the new iMac. However, Does it slow down your 800 drive when it has a 400 chained off of it? Or, if the 800 is the first drive connected to your iMac, do you maintain full speed?

If my MacBook Pro has a FireWire 800, AC powered hard drive attached, how should I connect another Mercury Elite FW 800 drive to the AC powered external drive, with an additional AC or just by FireWire? In other words, if the first drive in the chain (the one connected to the MacBook Pro) has AC power, does the second drive in the chain (connected to the first external drive) need AC power? Any cautions so I do not burn out my computer?

I have a real quick question about daisy chaining some firewire drives. I'm looking at buying an OWC Mercury for my macmini. I'm going to connect it via FW800. Can I then daisy chain a FW400 device to the OWC? The drive has 2 FW800 ports but only 1 FW400 so can this be done?

What happens when you have a FW400 repeater in a FW800 bus but no active FW400 peripherals?

I basically need to connect an older iMac to a new MBP but they both have different FW connections - I always get confused when it comes to cables so if anyone can point me in the right direction it'd be grand,

I just bought a 640gig Samsung 2.5 inch / 5400rpm drive and threw it in a FW800 case from Other world computing. Running some test using the QuickBench 4 and AJA system test shows me that this little bugger is almost as quick as my internal drive on my MacBook Pro (Model number: WDC WD6400BEVT-00A0RT0). How can this be???? I did a varity of test with different file sizes and the Samsung get 70 MB/s vs about 84 MB/s for the internal drive.
My internal drive is pretty full vs this external drive that is currently empty. I do a lot of video work / large gigabyte files on the drive so perhaps I have a defrag problem? I really expected my internal drive to blow the FW800 connected Samsung out the water?

I have a new macbook pro and after reading various threads I want to buy a gtech 320gb external drive. The only one I can track down is the firewire400. (at a reasonable price) The MB is FW800. will the FW400 work OK and is the speed significantly slower?

I have two new G-Drives attached via FW800. One drive keeps unmounting by itself. All of a sudden, I get a screen that says "The drive has been removed, you should always make sure to eject the drive properly from the etc etc.." First time I have ever had this problem. I have tried the eSATA connection and FW connection with the same result. Regardless on how I connect the drive, linked or direct. It's brand new. Could it be bad?

I bought a MacAlly GS350SUAB hard drive enclosure for the firewire 800 port. Before I made the purchase, I looked around for some FW800 drive xbench scores and found a few results:
[URL]
When I ran the xBench disk test on my drive, I was unimpressed. They weren't much better than when I plugged it in using the USB port.
Uncached Write34.81 MB/sec [4K blocks]
Uncached Write43.62 MB/sec [256K blocks]
Uncached Read18.11 MB/sec [4K blocks]
Uncached Read46.06 MB/sec [256K blocks]
I thought maybe xBench was sucking, so I timed how long it took to write a 831MB file to the drive using both USB and FW800, and it was actually faster (marginally) on USB. FW800 took 30 seconds, while USB took 28. Something doesn't seem right. Does anyone have any thoughts on why this could be? I do have a FW400 audio interface hooked up, but that is of course plugged in to the FW400 port and shouldn't make a difference. The hard drive I'm using came out of a Seagate FreeAgent. Is it possible it's just a really slow drive?

Could anyone recommend an external (FireWire 800) Hard Drive that they're using without issues with a Power Mac G5 (mine is a Dual Processor 2.3)?? I bought a couple of WD My Book Studio Edition but have no end of problems on FW800, and looking around here so is everyone else. LaCies seem to have similar problems, plus my own experiences in selling these and seeing FW ports falling off the enclosure's board, etc., puts me off them. Maxtors seem to have different issues and the new brown and orange Seagates are too fugly to even consider. So, anyone recommend a solution (250-500GB) that works fine with FW800 on a dual PMG5??

so I am in search of a new 500GB-1TB External Drive for Time Machine, and it has to have FW800 as well as USB 2.
I was thinking of getting an external chassis and buying my own hard drive, has anyone purchased a good external chassis with both ports, or a all in one drive that is worth the money?

I bought a brand new Seagate 400Gb hard drive for my PowerMac G4 MDD FW800. I installed it in the back bay, as a slave drive. When I power on the Mac, I get a blank grey screen. The original hard drive with OS 10.4.11 is set as the master, so I don't know why it won't boot properly. I've checked for bent pins, and I don't see any obvious ones, so I'm completely confuzzled.

First I wanted to upgrade my new mac mini with a Momentus XT but now I'm thinking about getting a "real" ssd + a FW800 drive for storage to have the huge speed boost of the ssd drive. Does anybody have this combination in his mini? What I want to know: How is the performance like of the external drive connected to FW800? Is it comparable to a standard internal hard drive?

I got two questions.
1) What would you guys say the best bang for your buck FireWire 800 is? I hear a lot of differing opinions on this one, so I'd like a couple suggestions, need over 500GB though. 750GB and up would probably be the best.
2) I've got 2 PATA hard-drives from my old Windows PC that crashed, what would you guys suggest doing about getting the data off of them? Most of the hard drive kits I found are for SATA, and the one I found for PATA was like $50 at Best Buy, I just want to get the data off these hard drives and junk 'em. I don't need bells and whistles and fancy enclosures.

I have just purchased a WD Studio Turbo extarnal/portable 320GB drive to use as a back-up and spare start-up disk. (I normally run Disk Warrior from an external.)
I have backed up my Macintosh HD to this WD drive using Super Duper and Super Duper indicates that everything has been copied ok.
However, when I plug in the FW800 cable to my MacBook Pro (old version) and restart holding down the Option key it doesn't show up as an alternative start-up disk.

This is in regards to the 2010 mini. I have been reading up on SSD, Hybrids and FW800 with a 7200. What is the easiest AND most effective/cost effective solution? If I went he FW800 route, can I use the same drive as my data storage drive? Will there be enough headroom to run the OS over FW and use the drive to stream movies playing in another room on Apple TV2 simultaneously? Will this give me a performance increase over the internal 5400 if I use the external 7200 for everything over FW800?
That is where my thoughts about the hybrid come into play. I know I can stream the iTunes content over USB2, which I have at the moment for the big drive. I would need to go buy an enclosure with FW800 to run it as a boot drive. I could use that same money and go get a 500GB Hybrid drive and install myself and leave the USB2 as data only. If the install is painless but tedious, I might just do that. If the FW800 route would be robust enough to run the OS and stream data to other devices simultaneously (ie use it as I would the regular internal drive), I might just do that and wait for SSD prices to come tumbling down and do a bigger internal SSD in the future.

I wasn't sure if it wouls be a bad idea if I wiped the interal hard drive while I'm booting from a recovery disk, then made a RAID 0 with the internal drive and my FW800 external drive. I'm nearing my max for the internal drive. I have a second FW400 drive backing up with Time Machine. I was hoping to just wipe, make the raid volume, and then restore from the Time Machine backup.
I guess even before that, my FW800 is not working in Lion. I reformatted while connected by USB, reset power management, and reset PRAM, but the firewire bus panics and takes out the Time Machine on FW400 as well. Is there a fix for this somewhere that I'm missing? I bought the FW800 drive for the above reason, only to run into a wall trying to make it work. I really don't want to do a RAID 0 with a USB connection.
I'm not going to try setting up the RAID 0 until I get the FW800 drive working reliably, but I was hoping to kill two birds with one stone.
Info:
iMac (24-inch Early 2008), Mac OS X (10.7.4)

When I got my external drive, I backed up my copy of leopard onto my drive so that if I lost the disks, I'd still have a copy.Such a thing has happended, and I need to do a clean install.Is it possible to install (reformat and install) from a FW400 drive?I know its possible to burn it to a dual layered dvd, but I don't think my iMac can burn them, and the fact that they're stupidly expensive.

If I have iTunes on an SSD drive (the boot drive in my Mac Mini), can it read the music library on a second rotational hard drive? I'd like not to have the large music library on a 120GB SSD drive.

I was convinced that I'd find an answer to this question on the forum, but even mroogle couldn't help me. I often have to use firewire target mode with my wife's MacBook (or friends' computers), and most of them only have firewire 400 ports. My new Mac Pro only has firewire 800 ports (which I find completely insane, considering the very useful FWTDM and the near ubiquity of FW400 on Macs...). Since FW400 PCI cards are so cheap (at least those on eBay), I thought it would be easier to install such a card in my Mac Pro. But the question remains: can all FW400 cards allow the target mode?

I recently bought a used (early 2008) MBPro 15" 2.5 SR to do some video editing. Unfortunately it will not recognize my Sony DV camera, or an external HD connected via FW400 or my 12" PB booted in target disk mode. The camera and the hard drive both mount instantly on my 12" PB and a friends 15" PB. Also, when I check the Firewire status under System Profiler all it says is: Warning: Unable to list FireWire devices (in red). This is regardless of what is connected to the port or if nothing is connected to the port. I have tried rebooting the PRAM and changing the Firewire port's network preference to OFF as recommended by this post: [URL]

i'd like to get the ATV but want to know what to expect. I hope that a FW 400 HD would be ok for streaming all content (as music is seamless with just the airport express), but it would even more sweet if i could just get an new AE and set up an external media library to stream over Airdisk.
so, is Airdisk and it's USB interface limitations still enough for the ATV? would be watching high quality DVD rips and lossless music files mostly.

1. I've just purchased the Formac Raven 1TB Drive (Firewire 400&800)
(Formatted into 2 Partitions Mac OS Extended Jour)2. I'm trying to copy large amounts of data (100-200GB) from either my 2 internal drives on my Dual 2.0Ghz G5 (OS 10.4.10) or from the USB 2.0 Freecom 500GB Drive to the Raven 1TB Drive.
3. After 4-20GB of data has been copied the copy window just sits there and won't go any further! I have to turn the Raven off and then back on again to stop it!
4. I have tried both FW400 and FW800 ports on my G5, but still the same problem.
5. I have verified all drives and repaired any errors and fixed permissions.
6. The Raven have been low level formatted, and split into 2 partitions.
7. I have a MacBook Pro Core 2 Duo (OS 10.4.10) , and have copied 200GB from it to the Raven without any probs!
8. Any ideas why the G5 won't allow me to copy large amounts of data?
Single file copying is fine! eg. Disk images of 4-7GB
Information:
MBP C2D 2.16Ghz, G5 Dual 2.0Ghz, iPod Mini 4Gb, iPod Nano 8Gb
Mac OS X (10.4.10)

My friend gave me his old Apple cube G4 + 15" Cinema display in like 1000 pieces. Its completely teared apart. I tried a lot, but it doesn't work. The original IDE cable wasn't included, so I bought one for 2 cents. It should work or not? Maybe the powersupply. I'm not sure. I don't believe actually that the hardware itself, like the motherboard is broken. When everything is into place and I connect the cube to the powersupply it boots immediately. I don't have to do anything. Harddrive spins and the superdrive makes some noise as well. This repeats itself every 5 seconds. The screen is connected and gets power through DVI, but no display. Both the cube and display have touch enabled buttons to switch it on, but they do not respond (I guess).. Motherboard gives 2 light. DS1 is green, DS2 is red.

I have a Dual 1.8 G5 and my hard drive has started to make a clicking sound every now and then. I believe it may be on the verge of dying anyday. Since i have space to put in another internal hard drive i am planning to get a WD Black Caviar 1TB and put it in.
Now my question is how do i move all my application from the old internal drive to the new internal drive.From what i have researched it seems that using a enclosure is the way to go but all the info i have seen is referring to replacing the drive rather adding a new one.I would like to move everything to the new drive and make that a master.What is the best way to perform this task?

I recently bought a macbook pro and am making the transition from a pc to mac. It's all gone well so far, but I'm not sure what to do with my music. I currently have about 200 gb of music on my external hard drive (connected to my pc.) The internal hard drive on my pc does not have space to accomodate the files on my external.
I do not have the "Copy files to iTunes music folder" currently enabled because my internal doesn't have space. (And I like having the original music files in a separate location as I have over 30,000 songs). I don't know how to transfer my external and music to my macbook, since I will have to reformat the drive (which would erase everything on it, therefore I somehow have to make a backup either on my mac or on my pc. but what to do about the iTunes .xml file and iTunes folder on the internal pc drive??).

I have been running out of hard drive space and have deleted a whole bunch of files... even deleted all the languages i didn't need from all my applications... about a week ago i freed up around 2GB.... but without saving and downloading anything my free space is now 70MB!! All I have been doing is watching streamed videos and I notice this reduces the drive space as I'm watching it!! Even opening firefox and some websites drops my memory by 0.1MB. I can't find anywhere where temporary files might be so i can delete them.
I never used to have this problem but I wonder if it has something to do with the fact that I now use wireless internet through a phone provider and a USB modem rather than my previous WiFi via cable broadband. Can anybody shed some light on what is stealing my memory when browsing?

I have an elderly Q950 with an external hard drive with everything backed up onto it. The external drive is a Micronet ADV1000E, with a sticker on the back saying it's Macintosh or PC compatible. I also have an iBook laptop, & PC Dell Inspiron 1300 laptop. As I have the 2 laptops, the Quadra hadn't been switched on for maybe one year. On the weekend I tried to get it to boot up (with & without the external drive switched on), but all it does is display a grey screen with an image of a 3.5" disk with a '?' in the middle. If I start up from a Norton 3.5" disk it still can't find the external or internal drive. If I try booting up with my finger in the shift key it doesn't want to know.
1. Any idea why the Quadra isn't seeing either the external or internal drive & what can I try to do?
2. Is there any way I can connect my external drive to either my iBook or Dell? At the moment I have no cables to connect the old & new - are cables available & if so any idea where from? I've looked high & low but so far no joy.
3. Is it possible to remove the hard drive from the Quadra or the external drive & put in an external drive enclosure, then connect that to either laptop? I see there are drive enclosures available which are Mac & pc compatible. This by the way would be a major undertaking for me. I'm by no means a computer dunce but would be wary of trying it.
