WD Elements 1TB External USB 2.0 Hard Drive

I was thinking about purchasing two of these hard drives. I want to use one at home an the other at work so i can bring work files home. I have a mac at work and a pc at home and wanted to know if I would just be able to plug it into both and have it work or can I only use it on the mac once it is formatted for the mac?

Is your MAC at work running OSX, and if so, which version? MACs cannot write to PC formatted drives natively. You may have issues, which can be fixed, but would require you installing software on your MAC at work, something which may be frowned upon or prohibited by your employer.
I forgot to include this in my other reply - OSX only has the "read only" limitation for NTFS. Most internal hard drives of PCs are formatted with this and can only be read by OSX. Most external hard drives come formatted as FAT32, which, as I said above, OSX provides read/write support for.

Is it possible to connect an external USB 2.0 hard drive to a Thunderbolt Display?

Hello,
Is it possible to connect an external USB 2.0 hard drive to a Thunderbolt Display and back up a MacBook Air to the external hard drive using Time Machine?
I intend to connect my MacBook Air to the Thunderbolt Display using a Thunderbolt cable.
I would also like to connect my printer via USB 2.0 to the Thunderbolt Display. Will this also work?
Effectively using the Thunderbolt Display as a USB hub or docking station.
Regards,
Ben

Ok, thanks.
My 1 cable to ThunderBolt Display objective
MacBook Air -> (via 1 x Thunderbolt cable) -> Thunderbolt Display -> (via 1 x USB cable) -> USB 2.0 external hard drive
I would like to know if this configuration is possible and Time Machine will run correctly.
Your 2 cable suggestion (I think)
MacBook Air -> (via 1 x Thunderbolt cable + 1 x USB cable) -> Thunderbolt Display + USB 2.0 external hard drive
This configuration requires 2 cables to disconnect/reconnect from my MacBook Air.

External USB 2.0 hard drive reconnects on its own after power-down

I have an external USB 2.0 hard drive which I'm trying to power off (after unmounting all partitions, of course) using:
$ udisksctl power-off --block-device /dev/sdb
When I do this, the drive spins back up after a few seconds. Only when I issue the same command again does the drive stay powered off.
I'm running:
linux 3.13.7-1
udisks2 2.1.3-1
This is what I see in the journal log when I:
- Plug in the drive's USB cable
- Issue the power-off command
- After the drive spins up again, issue the command again

What is interesting is that on first connect, the drive is using ehci-pci driver, then after the first try powering it off, the drive appears to reconnect using the ohci-pci driver. Not just that, it appears to 'jump' from one USB bus to another. How is this even possible?

Does anyone know how to fix this problem? Is it a device quirk, a driver bug or something?

Just to be sure, I rebooted my system, shut down lightdm from another VT, made sure that really nothing is using the drive, no partitions are mounted, no services that could try to use the drive (except udisks2.service, could this one be the problem? But how am I supposed to use the udisksctl command when the service isn't running?).
Tried the same command again. same result: I needed to run it twice in a row for it to 'take'.
What I find even more fascinating: how can a USB device jump from one USB bus to another like that? I've honestly never seen anything like this before :-)

External USB 2.0 Hard drive not showing up

I have a 120gb Western Digital external 2.0 USB hard drive.
When I plug the drive in (have tried both speeds of USB) nothing shows up.
The drive powers up and spins.
The first time I plugged it into the computer it ran perfectly. 5 minutes later after I restarted it would not show up.
I can confirm the drive works fine as it transferred data with no issue when it did show up.
I have tried the disk utility function and it just hangs and never resolves.
I have tried to look at it via the system profiler under the usb and again it just hangs.
This drive is used back and forth between a PC, my G4 Power book, and now this G5. For about 2 months it was working fine between the G4 and the PC. Just the other day it stopped working on the G4, and then when I tried it on the G5 I just got, as mentioned, it showed up the first time then nothing.
Any help would be fantastic.
Please note I'm not the most proficient in getting under the hood on these machines, so please talk slowly. lol

The USB disk icon is also lost. I had just finished re-formating the drive to the MAC format, backup up mail and all of my pictures - and 2 users of mail files. Shutdown the system to install Leopard from Tiger. My IMAC is 20 days old ... not a lot of files.
After Leopard was fully installed and updated with all fix's, I re-connected the drive, but it never appeared. A waited for a while .. no change, so I pulled the USB cable. Leopard give me a trap like error and said to old down the power button until powered off. When the system came back up .. its still not showing. I tried the Disk Util .. it does not see it also

External USB 2.0 Hard Drive

I have a External 2.0 usb hard drive that I use as a backup for my pictures, documents, videos etc. Currently I am using Windows XP but I want to get an Intel Based iMac. Can I just plug the hard drive in to transfer files or is it not that simple?
Thanks

I have a similar question but I am earlier in the process.
I want to transfer my files (iTunes, photos, etc) from my Windows XP Dell to my new iMac. I have an 80GB Iomega USB external hard drive that I can borrow from work. Should I format it in one manner (Fat32 or NTFS) before I start the whole process? And then is it just as simple as putting the files on the hard drive, ejecting it, and then plugging the USB into the iMac?
I guess my other question would be should I bother doing this, or just use an ethernet cable and connect the two computers and do it that way, if that is even possible!? I am just trying to get my ducks in a row before I make the big "switch"
thanks

External USB 3.0 Hard Drive not recognized

Please help!!!!
I had been using my hard drive for a while and everything was fine, but when I went to plug it in today nothing happened. The blue light still comes on, but there are no sounds. It does not show up in windows explorer (8). It does, however, show up under "remove hardware safely," "devices and printers" and, as USB Mass Storage Device under USB Controllers in Device Manger. It does NOT show up in disk management.
I have tried every way of unplugging and re-plugging the USB cable and power cord (along with restarting/shutting down the computer). I have tried using different USB ports. I have tried using a different USB cable. I have tried unistalling the USB Controller in Device Manager and re-installing it (and one time I tried uninstalling it, then unplugging the power, then plugging power).
Now, I have had it plugged into my computer for about an hour, and when I open Devices and Printers, I can see it there, but it keeps disappearing and re-appearing.... this is where I am at... I am at a loss of what else to try.
Any help would be GREATLY appreciated!!!
Thanks!!!!!

Have you tried it with another computer? Does that computer see it?

Possible to install on external USB 2.0 hard drive?

Is it possible?
I have leopard installed on my macbook pro, however i need tiger for final cut pro.
I am going to buy an external HD, and want to know if i can install tiger onto it? to use.....for the time being for FCP (some plugins not compatible)

I got a Sumo 320GB instead of the 250 .
Formatted in the way you need to boot in intel-mac. Installed OS X Tiger and it all works perfectly, and there is really no speed difference.
I do have a question, I can not access files from my internal HD now from Tiger. How do i allow Tiger to access my internal Leopard?

Journaling External FireWire and USB 2.0 Hard Drives?

I have several FireWire and USB 2.0 Hard Drives which I have always formatted as "Mac OS Extended (Journaled)".
I have been told that journaling is a waste of time with external HDs and, if anything, will slow them down slightly.
What is the general consensus on this forum?

Thank you for the swift response Malcolm.
I better explain why after all these years I am having doubts.
I am awaiting the delivery of a new piece of kit - a Western Digital HD TV Media player. Basically, you put your hi-def videos (H.264) on a USB 2.0 HD, plug it into the media player which is then plugged into your HDTV.
I have got hold of the manual which says that the supported USB file systems are "FAT32, NTFS and HFS+ (no journaling).
So I was wondering whether I will have to format the HD without Journaling to make it work?

Usb 3.0 hard drive doesn't work

can archlinux use usb3.0 as usb2.0?

this issue still exists when i upgrade the kernel to 3.5.5-1-ARCH
hi, everyone
i have a usb 3.0 hard drive and a laptop with usb 3.0 port.
when the hard drive is connected to the usb 3.0 port, the drive could not be found.
the dmesg output is listed below.
additinal info:
1) the usb 3.0 hard drive can be found when connected to usb 2.0 port.
2) the usb 2.0 hard drive can be found when connected to usb 3.0 port.
3) mouse works when connected to the usb 3.0 port.
it seems that it is not the linux driver's problem, because the mouse could work and the hard drive is found due to the dmesg.
is this a bug?
would someone help me?
thank you!

tail -f /var/log/messages.log is similar to the dmesg.
1) I have a usb 2.0 hard drive which could use the usb 3.0 port.
2) I remeber x230 with windows XP could use my usb 3.0 hard drive with the usb 3.0 port
3) so, it is a problem of archlinux rather than hardware?
thank you!

C200 Booting to USB attached iomega Hard Drive

hi guys.
Does anyone know if the C200 will boot to a USB attached Iomega Hard drive for use with their never now software
for system restore in case of hdd failure ?
Im not sure if the Bios will see the external hdd as a bootable device.
Thanks for any replies

It should.
Best regards.

Hey, can i clone my Macbook Pro internal hard drive and then paste it all onto a formated external hard drive, then make the Mac use the external as the primary hard drive?

If what doesn't work?
If cloning your internal drive to the external drive is not successful, I expect CCC will tell you so. Assuming that doesn't happen, you will have a bootable replica of the internal drive on the external drive once CCC has finished.
You can then do any of several things:
1. Replace your internal drive with a much larger one (320GB or 500GB, or even larger), and clone the external drive's contents onto the new drive so you'll have all your data in one place. Note that if you do this, you'll also need to buy an external drive that's large enough to back the new internal drive up on.
2. Boot from the external drive as a temporary measure while you clear at least 30-40GB of data off the internal drive, allowing you to keep using it and saving small amounts of data to it. The external drive will then contain the only copies of the files you've deleted from the internal drive, so you'll need a seond external drive large enough to back both the other drives up on.
If you can't comfortably clear a minimum of 30GB off the internal drive, you really need a larger internal drive right now, and you shouldn't bother fooling around with the inadequate one you have — you'll just quickly overfill it again.
3. Replace the optical drive in your MBP with a large conventional hard drive, giving you two hard drives inside the machine. You will then need one or more external drives large enough to back up both of the internal drives.
If you sense a theme here — back up, back up, back up — you are correct. It's flat-out foolhardy to own or use a computer without maintaining complete, up-to-date backups of everything at all times.

if you follow all 7 steps you can dl a trial here: http://prodesigntools.com/photoshop-elements-10-direct-download-links-pse-premiere-pre.htm l
and activate with your serial.
if you have a problem dl'g, you didn't follow all 7 steps. the most common error involves failing to meticulously follow steps 1,2 and/or 3 (which adds a cookie to your system enabling you to download the correct version from adobe.com).

It's not just you, I can't authorise my phone. It seemed to go down just after I started the update (it wasn't my fault though). I am using chrome, and it does not seem to be a firewall issue, or the bannerblock issue that I read about else where, since I dont have that program installed. Strange though how the support forum is still running. If I go to http://www.apple.com/support I get nothing, but googling topics allows me to see em.

1TB is missing from my hard drive. Is there a way to get them back without wiping my drive and reformatting everything?

I installed Windows 8 on my 3TB Fusion Drive, now about 1TB is missing from my hard drive. Is there a way to get them back without wiping my drive and reformatting everything?

No, I assigned 100GB to the Bootcamp partition. So my Macintosh HD should be still about 3TB but it only shows 2.2 TB. And when I try to put the Bootcamp partition back, it also shows that I would have about 2.3 TB combined. So almost a TB has just disappeared. It doesn't show up anywhere.
Also when I installed Windows 8 I saw about 800GB (which is most certainly my missing space) show up as Free space. Now my question would be If it is possible to get them back without wiping the whole drive.

Booting permanently from external (USB 3 or Thunderbolt) drive?

I'm interested in upgrading my 2010 iMac to one of the new 2012 models, specifically for their USB 3 and Thunderbolt port offerings.
My question is; if I have an external USB 3 or Thunderbolt drive enclosure with an SSD, can I *safely and reliably* boot from this external drive for as long as I own the iMac (ie, never use the 1 TB internal HDD that comes with the iMac)? I'm not interested in Fusion Drive, as I'd rather pay that $250 toward a speedier SSD and external drive that I can own and freely move among different machines.
But I've read different accounts in other forums about the reliability of using USB as your primary external boot source, namely since it relies on the CPU and you'll get slightly diminsihed performance and/or errors over time. Maybe Thunderbolt is the way to go? Any advice on this?
I see posts like this one (http://fortysomethinggeek.blogspot.ca/2012/10/blacx-5g-usb-30-update-fastest-usb -30.html) and it gives me hope, but I don't want to have to deal with random crashes attributable solely to my use of an external drive as my primary boot source. Is anyone else using this kind of external-only setup, and can you please let me know your thoughts and experiences thus far?
Thanks!

First and foremost: Are you using OPTION to try to select the USB-DVD to boot from?
The MacBook Air has to, and has to place a set of Apple supplied drivers on USB I think or has USB DVD support.

one feature Boot Camp Assistant has been broken never worked part of 10.6.6, to download drivers to put on CD/USB. So that is 5 months status: broken and unacknowledged officially.
