Ejecting USB 2 External hard disks?

I've just got some Freecom Toughdrive 250GB USB 2 drives.
I want to check something about ejecting them and I can't seem to find info about this, even from Freecom.
When you eject a USB 2 hard disk, should the disk then power down? My Freecom Toughdrives all remain "live" after ejecting (the ready light stays on and the disk is still spinning, you can feel the casing vibrate.) You get a little noise when the cable is pulled, as the disk suddenly spins down.
Ive tried 3 of these with my Mac Pro and my girlfriend's MacBook and all of them behave the same - is this normal or am I damaging them by unplugging them like that?

Note: since posting this, Freecom customer services got back to me, and apparently on a Mac, the bus-powered Toughdrives don't power down when ejected, but it's safe to unplug them anyway.
On PCs, they do power down if you use the "safely remove hardware" option.

My USB external hard disk won't work anymore after I updated to 10.4.10

As I said in title since it's quite urgent to me. ALL of my files is in my external hard drive. It's format as FAT or FAT32 I can't remember since I use it between mac and PC. More than that IT IS WORKING FINE UNDER PC. Before updating to Mac 10.4.10 I used my hard disk fine till I updated to this version. I plug in my usb port and after a hours it still won't be detected. I can find my hard disk in finder or desktop. I have tried plug my hard disk to other MacBook or Mac Pro but still won't work anymore. However it's working fine under PC or when I started my MacBKPRO as WindowsXP under bootcamp, my hard disk is working fine, too.
I have search this forum and seems someone have got the same problem as I face. I don't know what to do...and I feel so disappointed to Mac.

As Mac OS X has no known viruses in the wild, that leaves you with one of three possibilities.
1. When connected to the Windows machine, a virus has written over a critical boot block area which allows the drive to become crossplatform. Get the latest Windows virus detection software and make sure the drive is clean of Windows viruses.
2. The firmware that allows it to communicate driverless has become corrupted on the drive case. Replacing the drive case itself will eliminate that problem, as suggested earlier.
3. The directory damage is just enough that the boot block itself is damaged. Backup any critical data from the drive onto the Windows machine first, and run Alsoft Disk Warrior 4.0 to repair the directory and see if that works.
The fact that Mac OS X 10.3.9 won't read it basically eliminates this as a 10.4.10 problem. Only a boot block or firmware issue like this could make a drive not readable on one platform, but readable on another.
P.S. please note the nomenclature of Mac, versus MAC on this user tip, as it appears you haven't learned it:

MBP does not boot from a USB external hard disk (backup disk)

My MBP does not manage to boot from an external 1Tb LaCie desktop hard disk (USB 2.0) where I cloned my startup internal hard disk with SuperDuper! (I tried CCC too). Unfortunately, this is exactly the external hard drive I bought to clone my startup disk and I desperately need to have it bootable at startup.
As a matter of fact I cannot see anything at startup (option key pressed or not) without disconnecting it from the USB port. Just it seems that the system hangs up if I keep the drive connected at boot time!!!
Please, advice.
Thanks in advance,
Adolfo

Hi, thanks for the input.
I produced recovery media with the built in recovery media creator, and with ATI Home 2013. This was in the form of a usb flash drive for both types, and a cd as well in the case of ATI2013.
In all three cases when booting up with any of these media inserted, the boot hangs almost immediately and the Num Lock led lights and that's it.
I have set the boot sequence to
USB
CD
HDD,
Disabled Secure Boot in bios and switched off Fast Start in Power Options.
F12 does allow me to enter bios and change whatever settings I want.
This coupled with the fact that the option to go into recovery console has disappeared during the boot sequence leads me to think it is summat to do with the laptop settings rather than the assorted recovery media I have created.
Thanks again for coming back to me.

Problem with USB External Hard Disk Drive

I have similar problem with hard disk MK6025GAS in Sweex casing connected via USB as Raistlfiren in this post but I am not sure if it has something to do with kernel. The problem is that when I plug the hard disk via USB it is not even shown with in /dev/ or by fdisk -l. I had similar problems with the drive before but it was always shown in /dev.
I got same output from dmesg as Raistlfiren in the post before
# dmesg | tail

I was browsing net for a lot of time to find a solution but nothing helped a lot. The problem is closes to the one described on Gentoo Forum
I can see that it is recognized by computer since it is shown with lsusb

From the beginning I though and I still think that the partition table is screwed up but the programs like TestDisk and fixdisktable work only with disks shown in /dev/
Additionally, I have checked the content of /var/log/kernel.log

The only thing I understand from these logs is that the disk is blocked, therefore not listed in /dev.
Assuming the newer kernel problems I could try to use some older live linux CD to see if that would work. I am also thinking of connecting this hard drive directly to my laptop, using live linux CD and maybe check the output of hdparm. Is there anything else I could check or try?
Thank you for any help or suggestions

Thank you nTia89 for response. Sorry for not providing enough information.
I believe the problem is not system dependent. I have dual boot with windows and there the disk has also problems. However, I do have Arch32 with Kernel 2.6.30, using Gnome. hal and dbus are also running.
I did not tried to connect the disk to the computer directly, I will try it today.
Yesterday I have used SystemRescueCD 0.4.1 with Kernel 2.6.22. I wanted to see if it will be recognized by the system and placed in /dev/. Yes it was. This means that the problem highlighted in Gentoo forum can be true, but it doesn't solve my problem. I have tried to connect the drive several times to Arch and it was not shown in /dev/sd*, in SystemRescueCD it was placed as /dev/sdb. Now I am sure that the partition table is screwed up.
So I have started to play with the drive in SystemRescueCD with TestDisk and FixDiskTable but without success.

Also recognized 64 heads, 57231 cylinders and 32 sectors (same as from fdisk -l), which obviously differs from manufacturer disk geometry.

This string "FfEeSsNnBbUu" was repeating there for longer time and it was most probably related to debugging or a verbose mode of fixdisktable
As I have mentioned I will try to connect the disk directly to the computer and see what will happen.
Shall I try to correct the disk geometry to the one specified by manufacturer? Is it possible?
Any suggestions?

USB 3.0 doesn't recognize usb 3.0 external hard disk

Hi, I have a 500 GB WD 3.0 USB External hard disk (Elements 1042) It works fine on my two USB 2.0 ports but when I connect it to my USB 3.0 port it's not even recognized, however the USB 3.0 port works with all the others HD I have, what should I do?

Good Morning
The first thing that comes to mind is that there are no USB 3 host controller drivers installed on your operating System. Are the other hard drives that work in the Port USB 3 or USB 2. If they are USB 2 then I would go onto the Support page for your machine and look for USB 3 drivers and try them

External hard disk does not show in finder

WD usb external hard disk does not appear in finder. Disk utility sees it and will mount/unmount and eject. I ran repair disk util. and all is well but still does not appear in finder

Hey Hatter, Thanx for the input.
Among other things I tried was a terminal routine someone suggested with no luck and new drivers/firmware for the drive, again, no luck.
I still don't know for sure what caused my problem, but I re-partitioned the drive and re-formatted it and that seemed to solve the provlem. Sadly, I lost all my info that was backed up on that particular drive but hopefully it won't come back to bite me later.
Cheers!!

External hard disk compatibility with Macbook Pro

I am a PC user and I am thinking of getting a Macbook Pro but have some reservations regarding the following:
Will my existing USB external hard disk drives continue to work with MBP?
Will I have any folder sharing issues between my PCs and MBP?
Or, should I really need to dual boot or virtualize Windows 7 to avoid these issues?
Any tips on how to dual boot or virtualize Windows 7 in MBP would also be much appreciated.
Thanks!

Will my existing USB external hard disk drives continue to work with MBP?
There should be no problem. Can you tell us how the drives are formatted?
Will I have any folder sharing issues between my PCs and MBP?
You shouldn't have any issues it's very easy to set up. Read this: http://support.apple.com/kb/HT1812?viewlocale=en_US
Or, should I really need to dual boot or virtualize Windows 7 to avoid these issues?
That's up to you. If all you want to do is file sharing then there is no need to dual boot, simple networking will solve that problem.
Any tips on how to dual boot or virtualize Windows 7 in MBP would also be much appreciated.
You can use Boot Camp or Vitualization using Parallels or VM Ware Fusion. All three will allow you to run Windows on a Mac. If you go the Boot Camp route you have turned a partition of your Mac into a PC. If you use Fusion or Parallels this allows you to run MS Windows inside OS X. Performance for most tasks is excellent.
I would also suggest you study both:
Switch 101
Mac 101

How do i repair or recover data from a corrupt USB external hard drive that does not show up on my Mac desktop or disk utility

How do i repair or recover data from a corrupt USB external hard drive that does not show up on my Mac desktop or disk utility?
Last night i was using my external hard drive, for some reason the folder just closed and i couldn't find it on my desktop.
After googling solutions, i found it in the disk utilities, i clicked on the 'repair' button many times, but it said the 'error...' message.
So i ejected it to try again, now when i connect the USB external hard drive it doesn't show up on my desktop or disk utilities.
I really just want to either repair or recover the data on it because it literally has everything (documents, work files, photos etc) on it,
I downloaded an application to recover my files but it needs the USB to at least show up.recognise it which mine doesn't.
I know i should've backed it up on another USB, this definitely teaches me for next time to back up all my files.
Are the files lost forever or can i recover them by going to a shop or using a software?

Thank you for responding.
This might sound stupid since i'm not really knowledgeable with Macs,
but since all my files were moved from my mac computer to the external hard drive,
is it possible to recover those files through my Mac - like recovering deleted files?

I have a 1TB WD external hard disk, which suddenly cannot be detected in my system. When i connect the hardisk to the macbook, the disk appears and immediately disconnects with the message "Disk not properly ejected". Any advice ?

verify on another Mac if the same
WD is having issues with mavericks as you can see on the WD forum, did you install any WD software (never do that) when you connected the drive for the first time?
possible issue is a dead SATA bridge card or the new WD firmware w/ Mavericks.
SATA card issue
Your dead external hard drive is likely fine! Great hope for your 'faulty' external HD

External Hard disk cannot be detected by my MacBook Pro USB's

Hi
I have bought an external hard disk 2.5" and even though I have formatted it as FAT 32 still none of my 2 USB ports detect it. It is a hitachi drive 160 GB eSATA. I haven't use power with my external drive.
I ended up sharing it through a toshiba notebook I have for the kids running Windows XP and I transfer files though the Toshiba to the external drive. It's outrageous!!!
Any ideas?
thanks
Andreas

Hi Andreas,
OSX can recognize and use FAT32 partitions without additional help !
Your problem sounds to me as a power consumption problem of the external HD, meaning that the HD does need more power from the USB port than the MacBook Pro can deliver.
Best solution might indeed be to get the external HD on its own power supply.

Mountain lion ejects external hard disks

After upgrading to Mountainlion (March 5, 2013), my LaCie external hard disk (500 GB, used for TimeMachine) was spontaneously and improperly ejected, presumably by the OS.
(1) The disk had worked without problems under OS 10.7.
(2) The disk mounts properly on an older Mac (OS 10.3.2).
(3) The disk would not mount on a newer Mac also running OS 10.8.2.
I am currently reparing the disk using Disk Utility on the old Mac, but I hesitate to attempt mounting it again on my iMac (June 2008) running OS 10.8.3. Can anyone shed light on this problem? I know I am not the only one with this difficulty, so is Apple doing something about it?

It is very probably dying (I just had to replace a Lacie disk 250GB form 2008).
This disk has originally been formatted on the 10.3 and then never again?
You can format it again on 10.8, but you will loose the TM backup, so if you do that you have to make a new TM on another disk.
I would no longer trust this disk, and buy another (5 years is not bad at all). Take all you want to preserve off the Lacie on the old machine and copy it to the ML machine.

Problem ejecting external hard disk

i've an 80gb external hard disk that i use frequently with my macbook, and i haven't had any problems with it until a few days ago.
everytime i finish using my hard disk and want to turn it off, i'm unable to eject it thru finder or just by ctrl+click on it and selecting eject. if i do by that method, the whole computer just freezes and i'll need to hold on to the power button to shut it down.
i've even reinstalled my system TWICE to try to solve that problem until recently, i discovered a way to workaround it, which is to fire up disk utility and select the disk to unmount it.
is there anyway i could do to solve my problem here? it's quite a hassle to launch disk utility all the time for such a menial task. :/
P.S my external hdd has 2 partitions.

yes i have. on both partitions, and disk utility found no errors in both of them at all.
i've even formatted one of the partitions again.

Upgraded to 10.10.3, the external hard disk keep working and spinning after I ejected successfully, and the HHD keep lights up, feel unsafe to unplug it

I tried on two macbook air, same situation.
This never happen on 10.10.2 or previous version. (The HDD light will off and it will stop running after I ejected before.)
I feel unsafe to unplug the external hard disk when its still light up and running.
I am using Macbook book air 2012 and 2013 with seagate backup plus....
Anyone have same problem? how to fix it?
or its ok to unplug the HDD while the HDD light is still on and running?
MacBook Air, OS X Yosemite (10.10.3)

I have a G-Tech external hard drive that continues to spin after I have unmounted it and if I disconnect it while it is spinning it makes a very nasty sounding clunk noise. In my case it started doing this after I enabled FileVault a couple of years ago. I have found that if I unmount it and then wait 6 minutes it will stop spinning. It is inconvenient but I only use it once a week and the clunk sound is scary enough that I put up with the wait.

My external hard disk ( TRANSCEND ) is not working when i connect to usb..before it was working..

my external hard disk ( TRANSCEND ) is not working when i connect to usb..before it was working.

1. These are the iphone forums. So what does your question have to do with iPhones?
2. Contact Transcend for support.

Time achine. Each time I wake up my Mac. it says that I did not eject the disk properly. Do I have to eject the external hard drive before putting the Mac. to sleep?

Time Machine. Each time I wake up my Mac. it says that I did not eject the disk properly. Do I have to eject the external hard drive each time I put the Mac. to sleep?

If you do eject or disconnect that external drive before sleep, do you ever get that message?
Some Drives & chipsets will not work right with sleep, what brand/model is it?
