New to daisy chaining my external hard drives need some guidence on this

I have 2; 3.5 inch 7200rpm 1TB hard drives, & bought some external enclosures with firewire ports for them.
what would the steps be to set them up?
some things I cannot seem to get a clear answer for even after Google searches is;
say I have drive A & drive B together, with drive A plugged into the firewire port on my mac & drive B plugged into drive A. If I only need to work with content on drive B, do I have to have drive A running as well? even if I do not need to work with it?
I notice in mac os that devices show up as no names, well if I need to eject my drives how can I tell which is which when they both show up with the same no name? I dont want to accidentally eject the wrong drives in the wrong order.
So to prevent something like this I would like to know if there is a way to get mac os to name each hard drive? say drive A would be called photos & drive B music. Is there a way to get windows to see them with these same names as well as in mac os?
another thing is I have windows xp pro installed through parallels on my mac & would like to work with my daisy chained drives in this as well.
what ever I do I dont want to screw up my drives, I have important data on them.

You can rename the drives to be just about anything you choose. That will help you to make sure that you are disconnecting the correct drive. As for the daisy chaining issue, I have found that even though the enclosures have the ports for this, I tend to see more issues with random disconnects. As near as I can tell, the Firewire port may not be providing sufficient power to drive two 7200 RPM drives at the same time. I personally prefer to use one drive on my FW800 port and a second on my FW400 port. Yes, one of the dries gets a lower bus speed, but for the increase in drive stability, it actually tends to perform slightly better overall since there are fewer drive disconnects under heavy load.
You reference Windows XP and Parallels. Parallels allow you to specify to connect a drive to the Mac OS side, or to the virtual environment running Windows. This is easily managed. If you are referring to Boot Camp, then yes, they will still work, as the Boot Camp drivers you should have installed would have installed drivers for the Firewire port. One other thing to keep in mind is that depending upon how the drives are formatted, you might have read-only access to the drives under one of the two OSes. You can buy/download drivers to give you full read/write access to HFS+ drives under Windows, and similarly for NTFS drives under Mac OS. Also, if you choose to connect the drives to a virtual Windows environment, then they will not be available to your Mac OS unless they are shared from the Windows side.

  • My new iMac will not allow me to daisy chain my external hard drives - what can I do?!

    I just purchased the new late 2013 iMac 27" and all is wonderful except it will NOT allow me to daisy chain my external hard drives which is a HUGE problem because I'm a professional photographer & I won't be able to access my images unless I can sort this out.  I know I can purchase a new giant hard drive but i'd prefer not to because I have about 12 TB of data which will be expensive & time consuming to transfer & I'd also prefer not to have that much info tied into one device.  Ultimately I will need to get a Drive with multiple bays but I'd really like a short term solution that works for the drives I currently have.  Any help is GREATLY appreciated!  Thanks!!

    Why can't you daisy chain your drives. If it's because the iMac only has a Thunderbolt port and you have Firewire drivers purchase the Thunderport to Firewire adaptor from Apple: Apple Thunderbolt to FireWire Adapter - Apple Store (U.S.)

  • Cannot Daisy Chain My External Hard Drives on Macbook Pro Unibody

    I have a 2010 Macbook Pro 13.3.  I am trying to daisy chain my 2 external hard drive enclosures to my firewire 800 port.  The enclosures are manufactured by Vantec, model Nextar 3.  Both devices have 2 firewire 400/800 ports and they advertise that they are able to be daisy chained.
    My issue is:  I hook one to the other and power them both on and nothing seems to happen.  I can power one up and the drive will show up on my desktop, but when I power the second drive up, I get the pop up screen saying I have disconnected my device without properly shutting it down, and then the drive is gone.  I have tried connecting them several different ways.  Im not sure if its the external enclosures, if there is a process I'm supposed to follow, of if the Macbook Pro Unibody does not support daisy chaining firewire 800 devices.
    Please, if anybody has had the same experience and has been able to fix it, let me know.  I am in need of some serious hard drive spance and am going to return both enclosures if I cannot get them to work.
    Thank you.

    I'm having the same issue.
    I'v also found that I am able to daisy chain other drives throught the vantec drives.
    And that, when  I get the pop up screen saying I have disconnected my device without properly shutting it down, and the drive is gone. I'm only able to remount the drive after restarting the computer while the drive is conected and powered. It won't apear on other computers untill the reboot sequence is preformed.
    Strange,
    Let me knwo if you've found a solution.
    thanks,

  • Partitioning My External Hard Drive - need some help

    Greetings,
    Recently, i have bought an external hard drive, then enclosed it with a casing and connected it through firewire 800 on my iMac 20" 2.0Ghz late 2007 model. what i want is , on my external hard drive, i partitioned it into two, then one partition for my mac, and the other is for windows. wherein windows partition can also be read/write from my mac, and vice versa on my windows;
    am looking for a suggestion on how to make the other partition, the windows partition to be read/write from my mac, and can also be read/write on my windows;
    Really appreciate any help; thank you in advance.

  • Daisy Chain Camcorder- External Hard Drive (firewire)- PowerBook?

    Will it really cause problems? I'm going to buy a firewire card to avoid any fw bus problems but for now, would it drop frames and cause trouble?
    Thanks
    Vito

    It does for some, not for others. We always preach that you need the card for the additional bus so that we ensure that it will work.
    I myself never had a problem daisy chaining camera/deck/computer. Heck, I have even captured to my internal drive without dropping frames, so...guess I am special.
    Nah, others can do this, but most cannot, so we preach the conservative way of doing things.

  • I can not delete or copy new files to my Iomega external hard drive

    Hi,
    I can not delete or copy new files to my Iomega external hard drive. Opening hard drive folder I can see that I can not overwrite it. I have heard that I need to install some program for the external hard drive to operate properly in Mac.
    Please help what to install or there is some other option.
    Thnx

    I'm not the expert on this since I have never done it. It sounds like you may need a data rescue program like Data Rescue III. I believe you can download a demo and see if you can see the files. If you can, then you can buy the program and retrieve the files. I don't know if Disk Utility can restore them--I think they have to be visible but this is not something I have ever had to do.
    In the meantime, don't do anything with the drive--you don't want to overwrite any files. Hopefully all or most of the files are still there and you will be able to retrieve them. The less the drive is used, the better your chances are of retrieving the data.
    Forgive me for not realizing that there were files on the drive that you wanted to save. Upon re-reading your question, I now see that there were. I should have known to warn you, and my bad that I didn't.
    Good luck!

  • Can I create a "new" iTunes library on an external hard drive and transfer my iTune library to save space on my laptop

    Can I create a "new" iTunes library on an external hard drive and transfer my iTune library to save space on my laptop hard drive

    Yes. Just copy all your music to a folder on your external. Then delete the music on your computers hard drive.
    It is not quite that simple. If you do that you will end up with many broken links and will have to re-create your library from scratch .  iTunes does not like it when you move or rename files or folders and doing so between drives is guaranteed to result in exclamation marks indicating you have broken the links to all your media files.
    If you are content with moving the whole library to an external drive (usually the best thing for most people), try:
    iTunes: How to move [or copy] your music to a new computer [or another drive] - http://support.apple.com/kb/HT4527
    Quick answer if you use iTunes' default preferences settings:  Copy the entire iTunes folder (and in doing so all its subfolders and files) intact to the other drive.  Open iTunes and immediately hold down the Option (alt) key (shift on Windows), then guide it to the new location of the library.

    I made a bootable disc on an external hard drive, with Yosemite on it.  I am running Snow Leopard on my iMac.  How can I open the Yosemite disc from the desktop on my iMac?  Does the external hard drive need to be connected to my iMac by firewire to do that?

    Snow Leopard's Startup Disk pref can’t see Yosemite volumes. So the only way to switch from Snow Leopard to Yosemite is to do what Niel mentioned. Doesn't matter whether it's connected by USB or Firewire, although performance via FW would be faster.
    Are you saying that Yos/10.10, as a volume located in a mounted external drive won't appear as an option in Snow Leopard's Startup Disc, in Sys Prefs? I've never heard this one before. AFAIK any mounted volume, regardless of OS, should appear there. I would think that, if it appears in the Boot Picker/Startup Manager it would also appear and could be booted to from Snow's Startup Disk. I can't test this myself, since I don't have Yos. Is what you are saying documented somewhere?

  • Audio Distortion on FW400 Audio Interface Daisy Chained to FW800 Hard Drive

    Hi everyone! I’m an experienced Mac user in need of help resolving FireWire device issues.
    I received my 27” i7 iMac a couple of weeks ago running 10.6.2. After a long process of migrating over from my 9+ year old Dual 500 MHz G4 PowerMac tower, I was excited to set up two 1TB drives inside an OWC Mercury Elite Quad-Interface Dual HD enclosure via FW800. I then daisy chained my Focusrite Saffire 10 audio interface (FW400) to the HD enclosure via a FW800 to FW400 converter cable. To reiterate:
    i7 iMac (FW800 port) --> OWC Mercury Pro Quad-Interface Dual HD Case with 2X 1TB drives (FW800) --> Focusrite Saffire 10 audio interface (FW400)
    Although a lot of people may disagree, I wasn’t concerned about having my FW800 hard drives drop down to FW400 speeds because of the slower audio interface. I have read enough about the 1394 FW protocol and its ability to use something called beta clouds, allowing both FW400 and FW800 daisy chained devices to operate at their maximum speeds. So far, so good. The drives are reading/writing data fast.
    As many studio audiophiles have said, you should separate your audio recordings and projects from your startup disk. I’ve done so. However, call me naïve, but I did not imagine that every time my external drives read or wrote data, my audio interface would go into a state of distortion (like raising the gain on a track as high as it can go). When the activity of the disk drops below a certain level, the audio interface usually switches back to clean pristine audio. I am experiencing this within a studio environment and with simple CoreAudio iTunes playback via my audio interface. How is this possible? Am I doing something wrong or is there a blatant limitation with the FW chipset Apple is using for their single bus in the new iMacs? If anyone can provide me with a solution or a convenient work around, I will be very grateful!

    Thank you for the feedback, Rick. To shed some light on daisy chaining FW800 with FW400 devices, I provide the following quote from one FireWire technical article I came across on the web:
    +"The concept of beta clouds allows FireWire to keep all devices on the bus to operating at their maximum speeds. Devices are cluster together on a logical level in a cloud. The cloud operates as a single block at 800 Mb/sec. The borders of these clouds are where legacy devices are connected, operating normally. Each device operates at its highest speed."+
    In short, beta clouds allow both devices to operate at their highest speeds.
    Both the audio interface and the external hard drive enclosure has its own, connected power source.
    I wish I had the option to use USB2 with my audio interface, but it only has a FW400 connection.

  • Brand New iMac 24" internal or external hard drive upgrade to 1TB?

    I just purchased a brand new iMac 24" MB325LL with a 320GB hard drive. I currently have 432GB of data on my PC and I would like to upgrade the hard drive to 1TB. I have 2 options and I need your advice:
    Option #1 » Cost:CDN*$255*
    Buy a Samsung Spinpoint F1 1TB from DirectCanada.com for CDN$155 (tax+shipping included). Get it installed by a certified Apple technician for CDN$100 in Toronto. I doubt I can get it installed for a lower fee.
    Option #2 » Cost:CDN*$317*
    Buy a LaCie D2 1TB external hard drive with Firewire 800 for CDN$317 (tax+shipping included) either from a U.S. retailer (e.g. iUnitek) or a Canadian one. Prices at Canadian online retailers start from CDN$266 + CDN$37 (13% tax) + CDN$18 (shipping) = CDN$321, which is just CDN$4 more than in the States, taking into account the exchange rate.
    So, there you. From the financial point of view, the incentive is to get an internal hard drive, which I don't mind at all. I'd like to install Vista on a 30-40GB partition, if that makes a difference. If I were to get an external hard drive, I would keep all of my data (e.g. music, movies, documents, music, etc) on it and reserve the internal 320GB hard drive for system files and OS.
    What would justify paying a premium for an external hard drive other than portability? If I were to get one, I would need to be able to access it not only from my iMac's Vista partition, but also from my HP Vista laptop. Same applies to the internal hard drive. If I were to get a Samsung F1, I would still need to access my mac files from Vista's partition (when I boot into Vista) as well as from my HP Vista laptop (over wi-fi). FYI: I have no use for Time Machine, since I've never deleted a file which I needed to recover..well, maybe once or twice. What I DO need is a utility to synchronize files across machines. Hence, I will need some kind of program to automatically sync my iMac files with my HP laptop files. Currently, I utilize SyncBackSE to sync files between my HP laptop and my PC over Wi-Fi every morning at 6am. Works like a charm.
    That's my dilemma in a nutshell. Any comments, suggestions and words of wisdom are welcome.
    P.S. I'm also planning on upgrading RAM to 4GB. Newegg.ca is running a promotion (http://www.newegg.ca/Product/Product.aspx?Item=N82E16820227251): $72 CDN minus $20 USD mail-in rebate. It's not related to my question in any way, but some Canadians might find this info relevant.

    Well, I don't have the budget for both and as I've already pointed out, Time Machine does not address my needs. It's a great backup solution, but what I need is a synchronization solution. I need to have the same versions of basic files, such as music, photos, documents, and other miscellaneous stuff on my iMac and my HP Vista laptop. Even if I were to get a MacBook in the future, I would still need the same set-up. That way, if something happens to either my iMac or my MacBook, I would always be able to simply copy-paste files from one machine to another. That's, sort of, my version of a perfect backup solution...unless, there's an option to load up files from a Time Machine backup onto a separate one (e.g. MacBook). In the end, Time Machine only partially addresses my need in keeping 2 machines backed up in a sense that it only backs up one of them. My solution kills 2 birds with one stone. I would have 2 syncronized computers (e.g. iMac + HP Laptop, iMac + MacBook) AND both computers would serve as mutual backup sources, since whatever happens to one of them, I would always be able to copy data from the other.
    The problem arises when I factor in the sheer number of gigabytes required on the portable computer to mirror everything from the iMac, whether be it a Windows laptop or a MacBook. I would always have more data on my iMac than the available space on a smaller hard drive. I now have 432GB of stuff and I can presume that this number will only grow. Hence, at any given time I would be able to synchronize only the most essential files to the laptop. Ideally, I would need a NAS which would collect = synchronize data from both machines. That way, whenever files get modified, changes would automatically be transferred to the NAS and routed further down the chain to the iMac. It would work both ways, obviously. In that scenario, I don't need to worry about any of the computers, since whichever one fails on me, I would always have a copy of the entire collection of files. Now, that I doubt Time Machine can accomplish.

  • How do I transfer my data to my new macbook pro using an external hard drive?

    I've already set up my new MacBook Pro is my issue. It asked me if I'd like to "Migrate" my stuff or use an external hard drive etc but at the time I didn't transfer my data from my old MacBook yet. I was going to manually do it later as I had to wait for my External hard drive to back my old Mac up. Now it's that time and I have no idea how to do it. I believe I've researched best of my ability.
    I feel like I'm asking a pretty dumb question. If I were to just drag all my programs out like my Adobe Suite on to my new macbook pro would that work? I feel like that's just too easy and incorrect. Please and thank you.

    The Adobe suite can be downloaded free, you dont have to copy it at all, under standard CS6 Adobe rules, if you own the suite, you get 2 computers "activated at any one time"  Make sure, if youre not using the older computer, you deactivate the software under the HELP menu in Adobe.
    format the new drive in disk utility ......APPLICATIONS.....UTILITIES.....DISK UTILITIES.......select the external drive and format (if its new and empty!!!) under the ERASE button with Mac OSX extended journaled
    copy all your important stuff from older computer , pics, files, documents, personal anything.
    most of you apps, i ASSUME you bought in the (other than Adobe software, or Office suite, etc etc,..... obviously) in the MAC APP store, so you can reload them on the new computer without copying them , makes things very easy......just open APP STORE, and download what you already bought.
    really the only important things , is copy all important work files, documents, pictures, personal ABC...XYZ......  obviously.
    the migration is about emails, contacts, etc etc etc, also data, just because you passed it by at the time doesnt mean you still cant do it,    go to the SEARCH at menu at top and type in MIGRATION ASSISTANT  to do it again , since you passed it by at first .
    the only thing you NEED / SHOULD copy is all your personal stuff........Applications need to be reinstall from either ONLINE download,.......or from the MAC APP STORE,........  you cant just copy the apps over (in most cases) and toss them onto the new computer
    Nahh, there are no dumb questions, just dumb mistakes because you DIDNT ask any questions, and we all make those here and there.

    New thread on same old unaswered issues from others.
    My desktop crashed.  It  needs new harddrive.
    I religiously backup my info everyweek on my simplesave md1000h
    However, before I buy a new computer or replace the harddrive on my old computer, I want to at least get my Quicken Checking account info up and running on my wife's  laptop.
    When I plug in the usb for the md1000h into the laptop,
     it recognizes the  hardware is there but, does not show any files.
    I presume my laptop needs the software to run the simple save.
    However, there is nothing out there on the HP site.
    Can anyone confirm that this is the issue...that I need the software...if so, where can I download it from.
    I beleive the softweare came preloaded on the md1000....now I cant access that software....go figure.
    Any help is appreciated.   Thanks.  Greg

    I too have the exact same problem on my HP SimpleSave (sd500a) external hard drive. I got through to WDC, and they apparently support these devices now. They asked me to send them a copy of my purchase receipt in order to extend my warranty in their system in order to help me (ridiculous!!). I sent the scanned copy of the receipt to [email protected], and got an auto-reply that they will get back to me within 1 day. I also went on their website, and they refer to the device in their system as 'ED Caviar Blue EIDE Hard Drive'. It has the same serial number as my product from HP, so I guess they have acquired these products or at least support of them (?). In any case, I'm freaking out because I have tons of family pictures, video and my entire iTunes library on the device. If any one is able to get help for this, please respond. I am desperate to get this resolved.
