RAID Lacie Drives Daisy Chained Together?

This may be a stupid question but would like to know if anyone knows if it would be possible to RAID 5 x 2TB External Lacie drives which will be daisy chained together via Firewire 800? I would rather RAID them together rather than have them mount individually on the desktop where things start to get out of control. Any ideas?

Well we're editing a movie in Apple Pro Res HD and at the moment we're running a RAID array on the Mac Pro then there's the Xserve RAID and I feel then due to the need for more space having 5 Lacie drives also mounting on the desktop things will become hard to find and archive. Due to budget restraints we cannot go for another Xserve which would've been ideal we have to go for the cheaper option of daisy chaining the Lacie drives together in order to get about another 10TB to carry on with digitizing footage.

Will Final Cut work with 13 1TB drives daisy chained togerher

Will Final Cut work with 13 (1TB) Firewire 800 drives daisy chained (78 feet) together? Has any one done this? If so were there any problems?

Thanks for your advice guys.
I did run into problems, had to start computer with only my pre-existing SATA and FireWire 800 drives (connected to the back of my Mac), then I made sure the 14 FireWire 800 drives were turned off, attached the FireWire 800 cable to the front of my Mac, turned on the drives from closest to furthest in the drive chain (6'cables between each drive) and all of the drives came up on the desktop.
When I opened the FCP project that had media associated with the 14 drives I got the spinning wheel of death. After rebooting and restarting the gang of 14 I thought I would try to open one of the drives on the desktop, again the spinning wheel of death. Will move to plan B - 9" cables, plan C is installing the drives into two drive towers.

AppleTV and external hard drive daisy chaining

Hi,
Was wondering if this is possible, I have a large collection of music and dvd which I have ripped into itunes. This is now getting so big that I need to do something. I understand that you can connect an appletv to the tv and access itunes through an external hard drive connected to my MAC. However my question is this.
I have found an hard drive its by lacie called the lacie d2 this drive can be daisy chain through its firewire connection. Therefor was wondering if I brought one of these drives and daisy chained another as my collection grows would this still be accessible through appletv.

I had drives being backed up to drives on the same chain while working on another drive in the chain, or something along those lines. To be honest performance had dropped but not to any extent where it became a problem.
My biggest issue was that my drives were all 2 TB and I had need for contiguous space that exceeded that. For example my itunes media was more than 2 TB and it was simply more convenient on a 4 TB drive rather than 2 x 2 TB.
My new 4 TB drives have an eSATA connection which I decided to use by installing an eSATA card in my mac. I now have 3 x 4TB eSATA drives and 5 x 2TB FW800 drives, my e SATA controller has 4 ports and will allow me to continue to expand, as I could eventually use 5 x 2 TB drives in an array attached to each port if I ever needed them.
In addition to the possibility of greater contiguous storage eSATA runs at 3 Gbps in comparison to firewire's 800 Mbps.
Don't get me wrong firewire never really became a problem.

Connecting 2 Firewire Drives daisy chained on a MacBook Pro Retina: 1rst FW8-Dr is ejected by OSX 10.8.2 as soon as I power up the 2nd FW-800 Dr.

OSX 10.8.2 seems to eject a FW-800 Drive to any attempt to connect in daisy chain a second.
- Connecting one single Firewire-800 drive (G drive) seems to work fine (connection through a Thunderbolt-FW800 adapter)
- As soon as I try to connect a second FW-800 G drive in daisy chain, when I turn the power on to the second: Mountain Lion ejects to first with the message "improperly ejected" and both drives are not visible. I do not use separate power supply for the FW-Drives.
- The same thing happens with for the second drive instead of a true FW-800, it is an SSD 128 GB mounted on an enclosure with a FW-800 interface.

Hi Mate,
I've got a non-retina MBP i5, and it's not behaving like that, so no way should yours be. Can't hear it at all until it really comes under load. But even then it's relatively quiet. Quite concerning that it's happening to you with nothing loaded up.
Something is obviously taking up cpu power just by having the audio engine running, have you checked OSX Activity monitor and checked where your processor(s) are being used?
Also, check your audio options and make sure the audio buffer isn't set ridiculously low.
Agree that Apple expansion options are expansive - However, at least they're working on getting the software reduced, Logic X being an example of that.

Trying to record multiple tracks (24) in Garageband with 3 presonus firestudio devices daisy-chained together.

Please help !! I can record multiple tracks (8) on a single presonus firestudio, but now I'm trying to expand the number of tracks to 24 by daisy-chaining three firestudio devices.
The three units will sync up properly, and Garageband detects all of the input channels, but the recording doesn't pick up the input signals for the 2nd or 3rd device. It only picks up the signals from the first device. I read the manual and daisy-chained the devices by serial number (lowest to highest).
Any help would be greatly appreciated.
Thanks

Simple Hard Drive Daisy Chain Question

I'm not sure where to pose this question but since I've posted some here recently, I'll ask away.
I have a 1 TB external drive connected to my Mac via FW800. I'm using it to store media for my Apple TV. This drive also has an eSATA connection. Can I attach another drive with eSATA to this drive via that connection, even though that original drive is connected to the computer via FW800? I don't see why not, but wanted to ask before I make the purchase.
Thanks, guys.

Oh interesting. So I would have to link another HDD by using a firewire connection, not the eSATA connection. Hmmm, that stinks. Thank you.

Can I daisy-chain a G-RAID Pro 2TB with a bunch of other G-RAID's?

Hey there,
I'm wondering if there would be any issues adding a G-RAID Pro into my current daisy-chained G-RAID configuration.
- I've got seven 500GB G-RAID's all daisy-chained together and running into my G5.
- Two of my 500GB G-RAID's are RAIDed together so the first one is connected to the onboard Firewire 800 port of my G5 and the other to my additional Firewire PCI card.
- The remaining 5 drives are daisy-chained into the drive that is connected to the onboard FW 800.
This hasn't posed a problem thus far, but I'm wondering if adding a whole new G-RAID Pro is possible with this configuration, or if there's anything I should know before I decide. I left a message for the tech department at G-Tech but they're so busy over there I figured I check in here.
I'm thinking about getting the G-RAID Pro 2 TB because I have 2 projects coming up for which I'll need a whole lot more space than I currently have. If anybody has any other hard drive suggestions I'd be open to them as well, of course.
Thanks a lot for any thoughts,
Joni

Jerry, did you see my post the other day? I don't know if there is a conflict or not, but I've had some serious firewire problems for the last year and just last weekend I was unable to access any media files that were on a lacie for a specific project. And when I tried to copy the files (after closing fcp and running diskwarrior on the drive), I kept getting error messages. When I came in the next day and started the system with the graids disconnected, the lacie performed perfectly. Seems like there might be some sort of conflict. Or just a weird one time occurence. But since I've been having all sorts of weird inconsistent problems with firewire drives and I did have a mixture of lacie and gtech drives my instinct says it might be the source of the problem. I just installed a burly 5 bay sata enclosure, so my need for firewire drives, except for sneakernet, is over.
I post this kind of stuff with the hope that if someone is experiencing weird firewire behavior, they can try to eliminate at least this possible cause.

Thanks Steve!
One more question: Stayed throughput speeds more or less the same as original Firewire (since all my movies are on external disks) or has it become significantly slower?
I haven't done a careful side by side quantitative comparison of what I had on the older Macbook Pro (which had three Firewire800 disks chained together via FW800) versus the new Macbook Pro (which has thunderbolt into which I have connected three FW800 drives daisy chained via the adaptor), mainly because my employer supplied me with these computers and required I turn in the old one when they replenished it with the new one. However, I can say this -- one of the FW800 externals is used for Time Machine, another for making entire disk clones, and the third is for misc storage. I have seen Time Machine start up during a disk clone (with SuperDuper) and there seems to be no impact. The disk cloning is generally pretty intensive on disk and cpu resources, but thunderbolt seems to have a much bigger capacity for throughput than firewire and hence can apparently accommodate multiple streams of FW800 data going back and forth with no apparent impact on each other. The main limit seems to be the FW800 speed itself, not thunderbolt. I see ~ 60 MB/s or more which is as much as I have ever seen on FW800. Ultimately, the ideal setup will be thunderbolt drives daisy chained together, I would expect hundreds of MB/s, but I don't see many of these thunderbolt drives on the market yet. Even better would be solid state drives ...

Daisy-chaining LACIE drives

Hi folks,
Hope someone can help here. I have a LACIE drive which is my main drive for editing on FCP. It is nearly full up so I bought another to daisy-chain together to increase the overall storage capacity.
I've linked the two together through Firewire800 and then attached one drive to my mac, but instead of one drive coming up it sees two individual drives.
It was my impression doing this would mean I would see one drive on my system but with the storage capacity of both.
Can anyone help with this? It's my first experience doing this sort of thing and am a bit of a novice...
Thanks

but instead of one drive coming up it sees two individual drives.
That's exactly what is supposed to happen.
The signal from drive 2 is just being passed through drive 1.
If you want to make one great big drive out of several, you need to make them into a Concatenated RAID set.
Disk Utility's Help file has this to say, be sure to pay particular attention to the last sentence:
+"About concatenated RAID sets+
+You can create a single, large volume from several smaller disks by creating a concatenated RAID set, which is also called Just a Bunch of Disks (JBOD) or spanning. The concatenated RAID set acts as one large volume with the combined capacity of all the smaller disks. You can increase the size of a concatenated RAID set after it's been created by dragging more disks to it using Disk Utility.+
+A concatenated RAID set is helpful if you have a file, such as a database, that's larger than any of your disks. It’s also useful if you need to create a mirrored or striped RAID set with one large disk and two smaller disks.+
+If all the disks in the RAID set are about the same size, consider using a striped RAID set. A striped RAID set lets you access your data quicker.+
+Be sure to back up your data frequently. If any one of the drives is damaged, you will lose the data that’s on all the drives."+
If you simply want to add another Scratch Disk to FCP, use the System Preferences > Scratch Disk menu and click on one of the free "Set" buttons. When the current drive is full, FCP will just start using the next one in the list.

Daisy chain thunderbolt drives and RAID

Hi everyone!
I was wondering, is it possible to buy several thunderbold drives, daisy chain them, and then make them act like a RAID 5 ?
Another question would be: I looked around the lacie drives and they said they can be put as RAID 0 or 1, but when you daisy chain them, so every one of them become a RAID 0 or 1 independent from the other or do they act as one?
Thank you for the precisions!

I believe you may do that provided the iMac is at the end of the chain, so the external drive must be able to pass through the port. But Apple's information on chaining is in relation to their standalone displays which must terminate the chain. So I am assuming that may also apply in your case even though the iMac isn't a standalone display.
It may be much simpler to use an USB external drive.

Daisy chain an external drive

Just set up new iMac with a 2TB external Lacie drive, partitioned for Time Machine and SuperDuper, and connected with Firewire 800.
I want to also use my old 500GB Lacie external drive for temporarily holding unedited movies, whilst I work on them in Final Cut or iMovie.
Can I connect the old external drive to the new external drive using a Firewire 400 cable and without adversely effecting my set-up?
Looking ahead, is it true that there will be Thunderbolt adaptors to enable a second or third Firewire 800 connection(s)?
Would the above options be preferable to a Firewire Hub?
All views appreciated.

Yes as long as both are self powered, then daisy chaining them should not be a problem. If one drive is bus powered (not self powered) then it should be connect to a powered drive at the end of the chain, instead of into the iMac or mid chain where 3 or more drives are chained together.

Yes a FireWire 400 drive can be plugged into the 400 port of a 800 External Hard Drive (if so equipped) or into the spare FireWire 800 port by using either a 6 to 9 adapter or 6 to 9 FireWire cable.

Can't daisy chain Thunderbolt 1 and 2 drives

I have a Mac Mini server (mid 2011) with a Pegasus R4 connected via Thunderbolt that has been running fine. The Mini is running Lion Server.
Just recently I got a Lacie 2big drive with Thunderbolt 2. I assumed that TB2 was backwards compatible so daisy chaining the Lacie to the Pegasus wouldn't be an issue. But when I do so, the Lacie doesn't mount and Disk Utility cannot see it.
However, if I connect the Lacie directly to the Mini it mounts and works fine. So then I tried connecting the Pegasus to the Lacie. But now the Pegasus doesn't mount and can't be seen by Disk Utility or Promise Utility.
So, is the problem trying to daisy chain TB1 and TB2 devices together? Or is it the Mini? Or is it Lion?
Any help will be appreciated.

Thanks for the quick reply. The Pegasus is over 3 years old and I have never updated the firmware. I will do so.
However, I got everything to work. The one I thing I didn't try was rebooting with both drives daisy chained and turned on. This did it. I restarted many times but each time was with only one of the drives connected. Not sure why a reboot is necessary for the daisy chained device to be visible.

Daisy-Chained External Drive No Longer Mounting

I have two external hard drives daisy-chained (firewire 800) to my iMac. The hard drive directly connected my iMac mounts fine. The daisy-chained hard drive no longer mounts, after mounting perfectly fine for a few months. I've tried restarting, etc with no success. Any help would be appreciated.

moretoexplore wrote:
No, it does not mount directly. I did however try using the other hard drive's power cord and it mounted without problem. But this doesn't fix the problem.. only one drive is mounting. At least it seems I have ruled out a more serious problem with the drive itself. I'm contacting Lacie to get a new power cord. Hopefully, with a new power cord, this will resolve the issue and it isn't some sort of daisy-chain issue.
I think you have solved the problem by elimination.
You can prove that it's the power cord by using the "bad" one on the working drive. If it stops working, it's guaranteed to be the power cord.
I believe that there were some issues with some of the LaCie Power Supplies.

Will Aperture backup to a vault with daisy chained external hard drives

I am moving my Aperture library to a 6TB external drive. I want to back that up to a disaster drive consisting of 2 g-drives daisy chained, one 2TB and the other 4TB.
Will Aperture recognize the daisy chained drives as a single drive and backup the Aperture library to these drives as a single vault?

Caveat: answering your question requires one to make lots of assumptions, any one of which might change the answer. I do not know if Aperture would do so or not but personally I would not recommend it.
Note that daisy-chaining is simply a method of connecting drives; the drives themselves each remain fully independent. One needs to build a RAID array to combine independent volumes, and that is usually best done with fairly identical drives rather than with a 4TB and a 2TB.
I strongly believe that unless one is a true mass-storage expert very large Managed-Originals Libraries should be avoided. IMO far preferable is to instead use Refererenced-Originals Libraries.
Databases invariably perform better in numerous ways when smaller.

Daisy chain two external drives via Firewire, then connect one via USB to the TC?

Hi,
I have two external drives that have both Firewire and USB ports. My 1st generation 500 gb Time Capsule (maybe all of them?) only has USB ports so up til now, I have connected one or the other drive via USB. (I've tried to connect both to a powered USB hub but one drive has problems showing up. At this point I only use the one drive that shows up and connect it directly with no hub to the Time Capsue.)
My question is: Can I daisy chain the two drives via Firewire and then connect one of them (probably the one that has no problems connecting with USB) to the Time Capsule via USB?
Second, somewhat-related problem...
I don't know why one drive isn't connecting very well when directly connected to the Time Capsule. Both are Fantom drives. One is a 1TB, the one that has prblems connecting is a 250GB. I've tried connecting directly or through a powered hub. The 1B has no problems, the 250 gb won't show up most of the time and disconnects itself fairly quickly if it does connect. I've switched cables; that hasn't helped. The 1TB stays connected most of the time but sometimes it disconnects too. I suspect the Time Capsule just isn't able to deal with external drives so I don't puch it. It would be nice to be able to have both drives accessable through the TC though.
Thanks for any help.
Cheers,
John

Doing some experimentation, connecting the drives directly to the MBP:
- Neither of the two drives Firewire daisy-chained and going through the powered USB hub connected to the MBP mount. I was using old aliases on desktop.*They don't show up on network otherwise. (Each drive self-mounts with both Firewire and USB direct connections.)
*Even after making new aliases, neither drive will mount using their new aliases when directly connected (not through hub) with USB or Firewire (and Thunderbolt adapter.) That's weird.
- Both the 240 gb and the 1TB drives going through powered hub connected to MBP mount by themselves.
- Two drives daisy-chained via Firewire and one drive connected to the MBP via Firewire (and Thunderbolt adapter) self-mount. No surprise there but that doesn't help me as I want to have the drives further away from the MBP and connected to the Time Capsule, which doesn't have a Firewire port anyway...
- All of the USB and the Firewire cables work as does the Thunderbolt adapter. I tested them.
I wonder.... I have a Firewire to what appears to be an Ethernet connector. I wonder if that would be any good. I'm afraid to try it though...
