Connectiong an external thunderbolt hard drive to an older iMac via firewire to thunderbolt adapter, as my Mac doesn't have any thunderbolt entry?

Is there a possibility to connect an external thunderbolt hard drive to my iMac (originally Leopard 10.5.8. upgraded to Snow Leopard 10.6.3) via firewire to thunderbolt adapter, as my Mac doesn't have any thunderbolt, but has two firewire entries?
Would like to use the hard drive's big data stocking capacity of 8TB, but actual WD-HDDs of such a capacity have no more other entries than thunderbolt.

Basically, no. The Thunderbolt-Firewire adapter does not work "in reverse," meaning, you have to have a Thunderbolt port on your Mac in order to use it.
Most Thunderbolt drives that I have seen also have a USB 3 port. You could use that, but on on an older Mac that does not have a USB 3 port you will be limited to USB 2 speeds.

I have a Free Agent external backup hard drive connected to my iMac Intel desktop via USB. Why do I get an error message, from time to time, upon startup stating: "disk was disconnected improperly, always eject disk before disconnecting"?

I have a Free Agent external backup hard drive connected to my iMac Intel desktop via USB, I never unplug it. Why do I get an error message, from time to time, upon startup stating, "Disk was disconnected improperly. Always eject disk before disconnecting."?

I never unplug the external harddrive, and the error message comes up only occassionaly upon startup. Maybe the USB connection gets disrupted enough to cause the computer to see it as disconnected and then reconnected while the iMac is powered.

External USB Hard Drive not recognized on iMac HELP!!

I am currently using a i5 iMac running Lion 10.7.5
I have recently partitioned a Verbatim USB external hard drive and uploaded all my footage from a wedding. This was done with no problems and the QT videos could be opened from the hard drive.
A few weeks later, the hard drive does not show up in my finder. BUT it is recognized in disk utility. Here is a screen shot;
So first I ran "Verify" and it told me to repair disk. After clicking on Repair, I got this;
It is giving me the error message "Invalid B-Tree node"
Here is more info on the hard drive;
Name : Hitachi HTS545032B9A300 Media
          Type :           Disk
          Partition Map Scheme :           Master Boot Record

          Partition Number :           0
          S.M.A.R.T. Status :           Not Supported
Can someone give me a step by step on how to get the hard drive working again? It would mean the world to me as this footage is priceless and irreplaceable.
OR can you refer me to someone (Geek Squad? Apple Store?) that might be able to help me out?
Thanks in advance!

The error message invalid b-tree node size indicates that the directory on the disk is corrupt. The way that it can be repaired is to reformat as disk utiltiy says.
It is recommended that the data be backed up first before either of this solution are done.
Since it is not be recognized by the sytem at all it does sound like you can back it up now.
Do you have a backup?
If you don't there is every chance you may lose all your data.
You can check to see if a data recovery service can recover any data for you. If you go that route you are looking at spending $$$$

Why does my mac pro show 182GB of APPS on a 250GB hard drive with 190GB of space available 6.5 GB of photos when I don't have any photos on my laptop (all stored on a separate HD)

When I go into MY MAC and bring up the storage bar chart it is showing 250GB hard drive 190GB of space 6.5GB of photos (i do not have any photos stored) 182GB of APPS (i only have what came with the laptop + I have only downloaded no more then 5GB of other APPS) the APPS green bar has grown by 10GB today even when the laptop was turned off????? any help??
many thanks

Normally in most cases such as yours, reindexing Spotlight will correct the problem. Try it again.
http://support.apple.com/en-us/HT201716
This seems to be a common problem with Yosemite.
If that does not correct the problem, you may try SMC and PRAM resets:

http://web.archive.org/web/20140711222006/http://support.apple.com/kb/ht1379
(This is a guess on my part. No harm can come to the MBP performing these resets.)
The last option is a reinstall of the OSX.
May I assume that the overall amount of data is correct? If not, then we will have to look at OmniDiskSweeper and Grand Perspective.
Ciao.

How to use iPad (4th gen) to edit with iMovie - but using an external source such as a USB stick or external USB hard drive

Want to use my iPad (4th gen) to edit a movie using iMovie - easy enough if the movie file is on the iPad - but what if it's too large - can I keep the source file on a USB stick or external USB hard drive and edit from there? How can you do this?

You can't export any type of file using the camera connection kit, so a USB flash drive or SD card won't work.
There are some wireless external hard drives that can be used with the iPad.
The Kingston Wi-Drive, which costs $50 for the 16 Gigabyte, and then $30 more for every 16 gigs more. It works by you turning it on and then accessing the files on it from an app that you download on your iDevice. You can access music, movies, and other stuff. No connections or anything, it works like a WiFi connection, you connect to it from the setting on the iPad under wireless networks.
Then there is the Seagate GoFlex, which some would recommend over the Wi-Drive. But this one costs $199 and had 500 Gigabytes of storage. It works the sameway as the Kingston: no wires, runs over its wireless connection. You can actually fit up to 300 HD movies on it.
Another option:
Expand your iPad's storage capacity with HyperDrive

2.5" external USB hard drive not recognized by my iMac

I have a small 2.5" external USB hard drive that my intel iMac will not mount or see. My 12" G4 Powerbook sees it fine and it is formatted in Mac OS Extended. My iMac is bootcamped and XP on my iMac sees the drive but not OS X Tiger on the iMac, (wierd) I have Tiger on both my Macs too.
Why does the intel based OS X refuse to see this external 2.5 HD. It sees a 3.5" USB one I have but not the small one. I know it is software.

Hey coby,
Well thanks for the star. Not sure I deserve it.
i then tried connecting the drive to each USB port again, and voila! i have found one it works in. I guess my computer's ports must be a little worn.
Hmm well try looking inside and see if there's some smutz in there, if the contacts are dirty or bent or worn.
i was starting to think i would have to go out and get a USB hub to give it some more power.
Is it powered off the USB? If so that actually might be a good idea since that puts a lot of strain on the connectors. Even if it's self powered it might be a good idea since it would take the strain off an obviously flakey USB.

1 x iMac and 1 x Macbook Pro with iPhoto 11 on each and an external network hard drive

Sorry in advance if this has been asked already - I scrolled down to see but could'nt find it......
Anyways, here is my situation: I have approx 7 yrs worth of digital photos stored on my external network hard drive. I've recently turfed my Dell and replaced it with an iMac as my family's main computer. Now I have 2 Apple computers at home - the iMac and a Macbook Pro that I am its only user. Both have iPhoto 11. I've been playing around with the pgm and have been importing photos from my external network hard drive (not many but enough to get the idea of iPhoto) on both computers only to realize that the work I do on one is not reflected when I go on the other. After reading some of the comments in this forum, I now realize that a copy of the pics go right on the computer's hard drive.
Is it possible to just edit, etc the pics on my external network hard drive and replace the old pic with the edited one?
Also, is it possible, for the work I do on pics on one mac to appear in the other's iphoto library? Meaning, when I do "events" and "faces" on one mac, is it possible to see that work on the other?
If not, then at this rate, I will have 3 copies of the same photo - one on the external network hard drive, one on the iMac, and one on the Macbook pro!!! I've read some stuff ref iCloud and it sounds like this could be a possible solution but am not sure.
Any help would be greatly appreciated!!
Thx,
Craig

Sort of?
Is it possible to just edit, etc the pics on my external network hard drive and replace the old pic with the edited one?
That's a straight no. iPhoto is a Digital Asset Manager and as such always preserves the original file. Basically, to iPhoto, your original file is the "digital negative" and it protects that the same way a film shooter will protect his negative. So it will never edit or replace an original file.
Also, is it possible, for the work I do on pics on one mac to appear in the other's iphoto library? Meaning, when I do "events" and "faces" on one mac, is it possible to see that work on the other?
There are a couple of ways to make this happen.
A: If you only edit nd manipulate on one machine, then simply back up the library to the other machine. Net result: The same editions of the same photos on both machines.
B: Create one Library and share it across both machines - best way to do this is to put it on an external hard drive and then plug that into whatever machine needs the library at whatever time.
But... This can't be your "network hard drive". The disk needs to be formatted Mac OS Extended (Journaled)
I suspect that iCloud will make all of this moot, but until we see it in action we won't know for sure.

How do I transfer data from a hard drive to my new Imac

Hello,
First off, I don't know much about computers, so please forgive me if I sound stupid... Anyways, I had a PowerMac G5 that took a dump. The hard drive is still good and so is the info on it. I want to transfer the pictures, itunes library, and word docs to my new Imac. I thought I had this info backed up to EXTERNAL HD, but I think I did it wrong and the info is not there. Is there a way to transfer the info from my old G5 HD to my new Imac. Genius Bar guy already removed my HD from my G5. My G5 will not start up past the grey apple screen. Thanks for any help you can provide.

What Larry means is buy something similar to OWC Neptune 3.5" Oxford 934 FireWire 400 (1394A) Enclosure Kit for SATA Hard Drives up to 1TB. All Cables Included http://eshop.macsales.com/item/Other%20World%20Computing/NP35SFW/ and then connect your old hard drive to your new iMac with FireWire 400. Mount the disk and transfer the data.
A good solution for only $48 USD.

Can I install Aperture on an Iomega hard drive attached to my IMac and use it from there with iPhoto pix on the IMaac

Can I install Aperture on an external Ilmega hard drive attached to my IMac and run Aperture from there to use it with photos on my IMac iPhoto library?

It's usually best to have applications on the boot drive, so I'd turn your idea around: run Aperture from the internal disk and park iPhoto and maybe iTunes libraries on an external - which would free up space on the internal.

Can You Now Install Windows 7 64-bit On an External Thunderbolt Hard Drive?

Hi. Will Windows 7 see external Thunderbolt hard drives as internal and install it finally to an external hard drive (for Boot Camp)? Has anyone tried it yet? Thank you in advance.
Gbu.

Yep, it works great.
I bought the Thunderbolt adapter for my Seagate GoFlex. Use the Windows 7 install USB stick that Boot Camp makes. Each time Windows installer reboots, you need to hold the option key to reboot back to the new installation. If you miss it and the computer boots back to OS X, no problem, just reboot with option. Once Windows is finished, run Windows Support from your USB stick.
    When you try to select Boot Camp in the startup disk control pannel, there is only one 'Boot Camp' even if you have a Windows installation on your internal drive. When you boot into 'Boot Camp' there is a high quality beatiful black and white ASCII boot manager screen that Microsoft made. You'll see 'Windows 7' and 'Windows 7' to choose from. There is a freeware boot manager editor you can use to uniquely name your various Windows boots, or you can use Microsoft's cryptic text based editor. Windows doesn't do Thunderbolt plug and play, so if you're on an internal Windows and plug in the drive, it won't appear or even start up. Reboot and it'll be available in the boot manager.
    I plugged the drive in through the Thunderbolt display, and everything worked fine. I was sure I would have activation trouble with all the peripherals in the TB display, but there was none. In the Windows Device Manager, every last thing has a properly working driver. I've never seen a PC with every device working.
    It all works because Thunderbolt really is a PCI express slot, just like in a desktop machine. In the GoFlex enclosure, there's an ATA controller just like on an adapter card. Windows hasn't a clue that it's external.

Boot from external raid hard drive in new iMac 2012

Just owned iMac 2012 21.5", but seemed internal drive is pretty slower than my previous iMac 2008. Planning to buy external raid hard drive like Lacie 2big Raid or G-Tech 4tb G-Raid (Thunderbolt) to be my main boot drive instead of internal one. Would this would solve the problem?

If your new Late 2012 21.5" iMac was Not ordered with the Fusion Drive option, then it came with a much slower standard 5400 rpm hard drive. Your 2008 iMac had a 7200 rpm hard drive. That's why this one is slower.

I connected my external hard drive to my new imac to put all of the information from my macbook onto it. i have been working on the macbook now and want to reconnect the external hard drive so my imac is updated with the work. How is that done?

As I said, I don't use Time Machine, so it'd be best to wait for an "expert" answer, but, with my very limited knowledge, I'd say: probably not - so, for now, I'd suggest you read up on Time Machine:

Thunderbolt audio distortion during heavy Thunderbolt hard drive activity on MacBook Pro Retina 15 2012

I have a 2012 MacBook Pro Retina connected to a Thunderbolt Display, with Thunderbolt hard drives attached to that. Whenever I'm doing a big copy, or a Time Machine backup, any audio being played through the speakers becomes heavily distorted. If I switch to internal speakers, it's fine (but obviously not high-quality). As soon as drive activity quiets down, audio is fine again.
Anyone else having this problem and/or know of a fix? It's super aggravating to have to change speaker settings every hour when my backup kicks off!
Thanks!

I believe this issue is caused by bad ground coupling between the two devices, some of the induced charge can spark between connectors in the thunderbolt port causing computer to basicly freeze.
To solve this issue try touching the connectors outside metal part to your macbooks body first to discharge it, then while plugging int the connector do it at slight angle so the metal of the connector touches Mac's body.
This method has been working for me.

How to use AirPort Time Capsule 2TB as an external storage hard drive only?

I have a new AirPort Time Capsule 3TB, now I want to use my AirPort Time Capsule 2TB as an external storage hard drive only, how do I it?
I would like to connect the AirPort Time Capsule 2TB directly to my Mac Pro. using OS X 10.7.5.
I have erase disk and reset the 2TB to factory default, after that, I cannot make it to connect to my Mac. Please help.

The 2TB Time Capsule needs to connect to your 3TB Time Capsule using a wired Ethernet connection.
Connect from a LAN <--> port on the 3 TB Time Capsule to the WAN "O" port on the 2 TB Time Capsule and configure the 2TB Time Capsule in Bridge Mode and turn off the wireless function on the device as well.
Once that is done, you can connect your Mac directly to the 2TB Time Capsule using another Ethernet cable, or your Mac can connect to the network using the normal wireless network, if you prefer.
