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.

Can You Daisy Chain Firewire 400 and 800 Mixed?

I would like to purchase an External Drive. I'm looking at a FW800. What I'm wondering is, Can I daisy chain devices mixed in.
I Want to run a FW800 Bilingual cable from my Powerbook to the External Enclosure. From the Ext. Enclosure, I'd like to have take my second FW800 port and take a cable that converts Firewire 800 to Firewire 400 and plug in another item. Is this possible?
Can I mix and match FW devices using separate protocol in a daisy chain configuration?

Russ,
Yes, it is possible. I have a drive that works on FW800, FW400, or USB2. Connected to the second FW800 port on that, I have an adaptor cable, a FW400 cable to a FW400 drive, and another FW400 drive connected to that . All 3 drives are on the desktop of my PowerBook. When I read your post, I had the only first drive connected to the iBook with USB2.
The only problem I've run into was trying to copy a 200G drive on FW800 to a 250G drive on the FW400 port on the PowerBook. Working overnight, it managed to copy ONE Gigabyte! I hooked them up as they are now, and copied the whole shebang in about 45 minutes
I picked up an empty drive case, 800/400/USB2 combo from OWC and a 250G Maxtor drive at CompUSA for about $100 less than I could get a 250 FW800 drive anyplace. http://www.macsales.com

Can't daisy-chain Firewire drives reliably from 1-port Powerbook. Hub??

I have found that I cannot get a daisy-chained Firewire drive to mount more than 50% of the time. This problem doesn't happen with Tiger with the same drives. I have tried 4 different brands of late-model Firewire drives (Iomega, Smartdisk, Maxtor, and Seagate) with different cables and what happens is that a drive that is directly attached to the 12" Powerbook will mount, but the second chained drive fails to mount a majority of the time. Since I only have one Firewire port, this is preventing me from using more than one drive at a time, and I lost two Firewire drives to corruption today. Three out of four partitions lost contained bootable backups of Leopard and Tiger. Ouch!
This issue could prevent from using Leopard with my Powerbook, which is supposed to be Leopard-compatible. I can't remake the clones too easily with only being able to attach one drive at a time. I am thinking I will order a Firewire hub and try that, but I am not sure if that would be a solution, and I am wondering why I can always daisy-chain under Tiger, and not under Leopard. Does anyone have experience with Firewire hubs and Firewire operation details? Will I be able to get reliable Firewire with a hub?

I have exactly the same problem !
I have found this :
Using Multiple FireWire Devices at the Same Time
Power Macintosh computers can transfer perfect digital video (DV) on FireWire when no other devices are using the FireWire bus. If you have problems transferring digital video, make certain that no other FireWire devices are being used at the same time. Turning on a DV camera that is already connected may cause a FireWire hard disk to stop working. If this happens, turn off the camera and verify that the hard disk has recovered. Then unplug the FireWire cable from the camera, turn the camera on, and reconnect the FireWire cable to the camera. Check with the hard disk vendor for a possible firmware update to prevent this problem.

http://www.2ndwave.com/firewire.asp
At the moment I can't upset what I'm doing to test it but I intend to do that as soon as I finish copying transferring...
I have the following device attached to different firewire ports:
a firewire video device connecting my G5 Desktop to the TV screen
a firewire ibot
I thought I would give u a head start

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 thunderbolt and MacMini power

Hi, I am a little confused by Thunderbolt - can I daisy chain a FW 800 camera (via thunderbolt to fw800 adapter) through a Thunderbolt monitor to a Mac Mini and everything still work/ be identified as expected in the OS (i.e. the camera software I use to control the camera)?
Also - I was planning on buying a Mac Pro, however it is no longer on sale with no apparent window for a re (or new) release. Currently I use 2010 Mac Pros to control high frame rate FW 800 cameras plus read/write (via an esata card) to a hard drive array. Data transfer rates are about 60 MBps both from the camera and subsequently to the hard drives. Do you think the most powerful Mac Mini will be powerful enough for this application? I don't like buying without being sure, but similarly don't want to wait around any longer for a new MacPro release.
Many thanks,
Oli

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.

Can I daisy chain IDE and SATA drives w/ FW400?

I have an 250GB IDE drive in ann ext enclosure with two Firewire 400 ports. Can I daisy chain a SATA drive to this or does it have to be another IDE drive?

If both are in their own Firewire case then yes. The FW interface converts whatever internal interface it is so the computer only sees it as a FW device.

I have a Mac Pro tower with two internal Hard Discs, each one 2TB. I purchased a 3TB Time Capsule. But it does not allow me to back up because it says there is not enough back up space available. Between the two HDs there are 3.3TBs. Can I daisy chain TC?

I have a Mac Pro tower (OSX version 10.6.3) with two internal Hard Drives, each one 2TB.
I purchased a 3TB Time Capsule. But cannot back up because it tells me there is not enough space.
I have more than 3Tbs to store to the new TC.
Can I daisy chain two TCs to store the 4TBs?
How can I back up only the internal HD that is already full, without backing up the other one?
How can I do back up using Time Machine to back up the 3.5Tbs?
Do I need to purchase another external HD (that is not TC) to be able to back up all of my photos?

Can I daisy chain two TCs to store the 4TBs?
No, you cannot link to produce a single large partition.
But you can have two separate backup jobs.. and use each partition. That is hard on TM but you can easily get a different backup software for it.
How can I back up only the internal HD that is already full, without backing up the other one?
In TM you do a different setup and exclude the other drive.
But it is better to use an alternative software IMHO.
How can I do back up using Time Machine to back up the 3.5Tbs?
You would need to use a network drive of more than 4TB .. it would also take forever. This is just wrong way to do it. Although you can buy a NAS that will work with Time Machine and load it with disks 16TB is possible.. if you can get a second mortgage.. the fragile nature of TM on 3rd party devices.. would leave me in cold sweat if anything went wrong.
TM is excellent at keeping incremental backups of files that keep changing.. as such you should use TM to backup your OS disk and main user directory.. exclude all files and directories that never change. Back them up separately.
Do I need to purchase another external HD (that is not TC) to be able to back up all of my photos?
Yes, that is a much better idea. You want to store photos safely and you want to store them in multiple places. If you have multiple TB of photos, dedicate a couple of disks to the backup. ie have at least two copies.. not in backup format.. in straight copy format if possible.. so you can keep one of the disks offsite.
I would be using your MacPro internal disk access, to place the disk onto sata bus and do the copy disk to disk direct. Or even buy esata card.. or sata to esata converter cable so you can use esata box. That will beat any other transfer speed except thunderbolt for which you would need third mortgage. (The MORT in mortgage is significant).
The great jurist Sir Edward Coke, who lived from 1552 to 1634, has explained why the term mortgage comes from the Old French words mort, "dead," and gage, "pledge." It seemed to him that it had to do with the doubtfulness of whether or not the mortgagor will pay the debt.

How many FW devices can you daisy chain?

Have a new iMac w/ one FW800 port. Need to daisy chain eight FW800 hard drives, two FW400 hard drives, and one FW400 DigiDesign Digi002 ProTools mixing board. I was planning on daisy chaining all the FW800 drives then coming out of the last of those with a FW800 to FW400 cable into the first FW400 drive, daisy chaining to the 2nd FW400 drive, then daisy chain from it into the FW400 ProTools mixing board. I know that's a lot of chaining but at the moment those are the devices I have to work with. I have A LOT of video and audio information I need to retain. Seems to me that I read somewhere about a maximum length a firewire daisy chain could be but haven't found any more reference to it when I just looked. All of the devices have their own power supplies so I don't believe they will be drawing much, if any power from the chain. Anybody know of any problems with this setup?

Thanks for the info.
I've tried several scenarios and combinations what I've found is that I can put all the FW800 drives in a daisy chain then put the 1st FW400 drive in and lastly the Digi002 mixing board (which is FW400). When I try to add to this any more drives I get unpredictable results. I have therefore bough another 2TB external drive and hooked it up through USB 2.0 and copied many files to it from the older FW400 drives as well as the only FW800 drive that ever game me headaches. It should be noted that it is a Western Digital My Book drive. It seems like it would be a great drive having FW800, FW400, and USB 2.0 connections. In practice, however, I have had LOTS of problems both on my Macs and PCs I tried using it on. I recommend strongly that you avoid using any MY Book drives. I'm having better luck with practically any other manufacturer, including what I would normally consider no names like SimpleTech and Buffalo. Those drives seem much more stable.

How many firewire drives can I daisy chain on the mac mini

How many firewire g-drives can I daisy chain on my mac mini

How many firewire g-drives can I daisy chain on my mac mini
From personal experience, if they are bus powered portable drives,
the answer is none. For what ever reason, they are draw a lot of
power and are probably near the edge of the bus powering specs.
Then again, these were the fastest of all the portable FW drives that
I have (Iomega and Seagate being the others), which may have
something to do with it.
I had also noticed an issue with them even with USB. Plugging one
into the Mini or even a powered USB hub would be fine, but 2 would cause
both to be inaccessible, unless I used a couple of USB "Y" cables
that would distribute the power across other ports.
If they are externally powered, you could string a bunch.

Imac 5k daisy chain thunderbolt display?

Hello everyone. Quick question on iMac 5k. Can I daisy chain 2 thunderbolt displays to an iMac 5k? I currently have one thunderbolt display connect to it, want to see if i can add another thunderbolt display. Thank you for the help.

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.

Not directly (see question 16 above), but it will work if you connect a Thunderbolt disk drive (with two Thunderbolt ports) between the displays.

Daisy-chaining firewire 400 and firewire 800?

I would like to daisy-chain two Western Digital MyBook Pros to a Macbook:
- FW 400 from Macbook to first drive
- FW 800 between the drives
Would this work or not? I have one of those, they have 2 x FW 800, 1 x FW 400, 1 x USB at back.
(If not, I'll buy a 'Premium' which has 2 x FW 400, and 1 x USB..)

I'm not sure if the hardware in the first drive, that's connected by firewire 400 is "smart" enough to jump the data over to the FW800 connectors for daisy chaining.
Just pulled this from the WD site. I would say this indicates it would work. You won't get more speed but they should work daisy chained. This indicates the drive is smart enough to do this.
+Question: Will Western Digital FireWire 400 (1394a) external hard drives work connected to a FireWire 800 (1394b) port?+
+Answer: The FireWire 800 Specification (1394b) states that FireWire 400 devices will work while connected to a FireWire 800 (1394b) port. The FireWire 400 cable (4-6 pin or 6-6 pin) will not connect to a FireWire 800 port (9 pin) therefore you will need to connect the hard drive using a FireWire 400 to FireWire 800 cable (1394a to 1394b cable). These cables are available at most computer stores.+

Can i daisy chain external drives

I have 3 drives but only 2 800 wire ports. Can I daisy chain, or use a 400 wire?

daisy chaining should work fine. I used to have about 11 drives chained (which was pushing the envelope - but it worked with dv material). If at all possible, avoid firewire 400 as it will reduce your thruput.
