USB External HDD not recognised in OSX 10.5.4

Hi,
I am attempting to use an ISOGEAR250 2.5" IDE external HDD on my iMac.
This deviceis advertised as 'compatible with OS/X', which is in fact only true up until version 10.4.9.
The device is not detected on any OS/X version with the IOUSBMassStorrageClass.kext or IOUSBfamily.kext kernel extensions of any version of OS/X past 10.4.9.
The only way to get this device to detect on Leopard is to revert the specific kernel extensions to earlier versions, and use the USB Prober utility. This is quite a dangerous exercise, and can lead to operating system instability.
I have tried the device on numerous Apple computers, and it only works on the ones with OS/X 10.4.9 or earlier installed. I have also experimented with many different file system formats. This device works fine on Windows machines, including Windows in Bootcamp, and Windows using VMWare or Parallels.
For your information, the device does turn up in the System Profiler with the following info, but will refuse to mount with kernel extensions past version 10.4.9:
USB4500 FW1.04:
Version: 0.001
Bus Power (mA): 500
Speed: Up to 480 Mb/sec
Manufacturer: DATAST0R Technology Corp
Product ID: 0x4500
Serial Number: 1966XXXXXXXXXXXX (I added in the X's)
Vendor ID: 0xed06
If I plug the HDD in while my iMac is sleeping, it will wake up the iMac.
I have tried the device on both the iMac's built-in USB ports, as well as with a powered USB hub.
Numerous other users have had similar of the same problem
(see: http://discussions.apple.com/thread.jspa?messageID=7835455), and yet Apple has not yet rectified the problem, which is clearly arising from the update to the operating system, and not the device itself.
Does anyone have a fix for this problem, aside from reverting the kernel extensions and using the USB prober?
Thanks for your help,
Cal

From searching the web, I am tempted to say the Iso Gear is quite an exotic device.
It's up to Astone them to deliver a firmware upgrade for their device to work with Mac OS X 10.5, as Apple probably follows USB 2.0 standards when accepting (or not) an external hard drive.
diskutil became more picky in 10.5 (been bitten myself) but still, I am not sure whether this is due to Apples development teams faults or due to to Astone following standards.
There has been an issue in 2006 with LaCie drives on OS X 10.4 which were resolved by their firmware upgrade.
I know this is of no help to you, but consider not just talking on Apple forums about this but also on Astone help channels.

1.5TB external HDD not recognised on various laptops

Hi,
I was wondering if anyone could help me.
I bought my toshiba 1.5 terrabyte external harddrive just over a year ago. It works fine on my other laptop and my boyfriend's laptop but when I connected it to four other new laptops (all different brands) recently it was not recognised on these laptops at all.
Is there something wrong with my external or is something on these computers blocking it from being recognised? Do you know how I can fix this problem?
Many Thanks!

Hello
And if you connect the external HDD to your and boyfriends notebook everything is still ok? You have only problems with new notebooks?
Well thats really strange Have you tested another USB cable and different USB ports?
Maybe on the new notebooks the antivirus or firewall program is blocking the access to external drive. Check your security software and allow external devices.

External HDD not recognised in Mac Book Pro

I am trying to connect a external HDD to the MacBook Pro. The external HDD used is Seagate FreeAgent GoFlex 1 TB powered by a USB cord connected to the laptop. The light on the HDD is not glowing neither does it feel like moving when touched.
Can somebody come back with a solution to get the HDD working on the Mac?

By placing the HDD in a different enclosure, one would be testing if the enclosure circuitry is faulty. Since it works on a PC, then that is not the problem.
noondaywitch may be on the right track. I note that your HDD has an optional Firewire connector available. You might order that or get a 'Y' connector where there are two USB connectors that you would insert in two USB ports on your MBP thus gaining more power for the Seagate. No guarantees of success with either option.
Ciao.

External Hdd not detected

Hi guys,
I've got this issue where my Macbook Air cannot detect my external hdd (not showing up on disk utility), where as my Mac Mini can. I assume it's a software issue. Both are running OSX Mavericks (Latest edition) and there is nothing wrong with my USB port in the Air (detects my mouse, flash drive etc.).
The hdds' LED no longer flashes when plugged in the Air but functions fine when plugged in the Mac Mini.
Is there any manual reset command (through Terminal) or setting in the Macbook Air without having to factory reset?
Thanks in advance for your help!

If the hard drive is bus powered (it doesn't have an independent power supply) the MBA may not be supplying enough power to the drive. This isn't an uncommon problem. I have a cheap external at work with this problem which I solved by plugging it into a powered USB hub instead of directly into the computer. Had that not worked I'd have tried finding an external power supply for the drive - or junking the enclosure.

Automount of SD card & USB external HDD with strange KDE pop up msg

Today I reviewed lots of threads posted over the last year and some bug reports too about this issue, but it's happening for me too. Both SD card and USB external HDD have autodetectable filesystems on them because I can mount them by hand with "mount /dev/mmcblk0p1 /mnt" and "mount /dev/sdb1 /mnt". But it would be nice if I didn't have to do that.
Although I didn't notice which explicit install that I did pulled them in as dependencies, I do have udisk2 and polkit installed. Also installed udiskie as a wrapper. I've been mounting these volumes by hand before now because I feel like I'm still learning the ropes of The Arch Way and guessed (apparently incorrectly) that mounting volumes by hand was just part of "The Arch Way". But based on some threads here and some bug reports, I guess this used to work in Arch but has been causing some problems for some people lately when they upgrade. I just installed Arch for the first time (using the 2015.02.01 iso image), so I don't have any background to go on.
So what is The Arch Way for automounting external drives? I've skimmed the wiki article for this and because "Development of udisks has ceased in favor of udisks2." it seems that udisks2 is preferred. But it got installed and the daemon is running for me. The user is in the wheel group. dbus is running (though like one person who filed a bug, I too have several instances of dbus in my ps -aux output and I'm not sure if that is as it should be or not). I've done no special configuration ("not wittingly" anyway; I promise, my name is not James Clapper) that I think would have affected this.
So for a newb with no special preference, how should automounting be configured in a new Arch system? In other words, what should be my first steps in trying to solve this problem for myself? I know there are lots of different ways to skin this cat, but I'd prefer the simplest and most elegant solution that does not depend on KDE or GNOME or other unnecessary tools. I've just (with this Arch system I just installed) begun using i3wm and I think I'll be sticking with it. That said, however, it's clear that I inadvertently/unwittingly managed to get some elements of KDE into memory as the following http://gamonics.org/img/2015-02-26-1731 … _scrot.png shows. This popped up both times, when I plugged in my SD card and when I plugged in my USB drive. Any thoughts on what's going on here? I did install okular explicitly because I think it's one of the best PDF viewers, but I don't understand why KDE is reporting anything to me when I'm running i3 and insert an SD card or a USB disk.
And in the terminal, I get this output (apparently from udiskie):
[root@archippocrates archie]# Failed to show notification: The connection is closed
not adding /org/freedesktop/UDisks/devices/mmcblk0: unhandled device
mounted /org/freedesktop/UDisks/devices/mmcblk0p1 on /media/3532-3338
Failed to show notification: The connection is closed
Although the volume does get mounted automatically.
Thanks for any thoughts.

I personally can't answer the question of "simplest and most elegant" way of mounting devices. It all depends on what you want. If you expect more exotic functionality, say correct unmounting of devices if they were disconnected during a sleep cycle, there's probably no way around udisks2. For that you get a complex piece of software prone to... unexpected behaviour. Mind you some of it is related to front-ends like GVFS.
As to your KDE issues, last I checked mount handling was disabled by default there, but you can control it manually (see man kcmshell4). Though I haven't followed up on KDE 5 developments. If going with udisks2, I'd recommend using devmon from the udevil package as a front-end (more details on the wiki udisks page).
PS: multiple dbus instances are expected, check the user names and specified arguments in the ps output.
edit: grammar. :X

In the iCloud preference pane, uncheck the box marked Calendars & Reminders if it's checked. You may get an alert that one or more calendars will be deleted from your computer. Confirm. The calendars won't be deleted from iCloud. Leave the preference pane open.
Quit Reminders if it's running, and also quit Calendar or iCal.
Triple-click the line below on this page to select it:
~/Library/Calendars/Calendar Cache
Right-click or control-click the highlighted line and select
Services ▹ Reveal
from the contextual menu.* A Finder window should open with a file named "Calendar Cache" selected.
Move the selected file to the Trash. There may be one or two other files in the same folder with names that begin in "Calendar Cache". If so, delete those files too.
If you unchecked the box in the iCloud preference pane, check it again and close the preference pane.
Launch Reminders and test.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select

from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.

Maxtor USB external drive not displayed anywhere. How do I navigate this?

The drive is plugged in the USB port, however it does not show up on my MacBook air. It is formatted for PC and I wish to download music files then reformat it to use with my MacBook. Thanks for the help in advance.

Howdy matthewjh,
It sounds like you have this USB external HDD that does not appear anywhere on your Mac. Assuming it is formatted as FAT-32 I would use the troubleshooting information for USB devices not working in Yosemite, named:
OS X Yosemite: If a USB device isn’t working
If your USB device isn’t working, there are several things you can try to solve the problem
If a USB device isn’t working properly, make sure you connected it to your computer correctly, plugged it into a power outlet if it has a power cord, and installed any software it needs.
Check power and cables:
Make sure the USB device is turned on and its cables are properly connected.
Check for missing software:
Make sure you installed the latest software for your device. Visit the manufacturer’s website for any updates.
If the device is connected to a USB hub:
Make sure the device and the hub are the same speed. Connect USB 3.0 SuperSpeed devices to a USB 3.0 SuperSpeed HUB, USB 2.0 Hi-Speed devices to a USB 2.0 Hi-Speed hub, and so on.
If the device doesn’t have a power cord and is plugged into another USB device that doesn’t have a power cord:
Try plugging the device directly into your computer’s USB port or into a USB device that does have a power cord. You might need to disconnect and reconnect the other device as well, if it has stopped responding.
If you have many devices connected to your Mac:
Disconnect all USB devices except the device you’re testing, an Apple keyboard, and an Apple mouse. Make sure that the device is connected directly to the computer, and that any hubs or extension cables are disconnected. If you can use the device now, the problem may be with one of the other USB devices or hubs you had connected to your computer. Try reconnecting them, one by one, to your computer. When you find the device causing the problem, review its documentation for further troubleshooting steps.
Verify that the device appears in System Information:
Choose Apple menu > About This Mac. In the window that appears, click Overview, then click the System Report button to open System Information.
In the window that appears, see if the USB device is listed below Hardware in the Contents list. If the device appears but does not work, review the device’s documentation for further troubleshooting steps.
Restart apps:
Quit and restart any apps that use the device.
Restart your Mac:
Choose Apple menu > Restart.
Thank you for using Apple Support Communities.
All the very best,
Sterling

USB External HDD Enclosure with a 500GB HDD!!

Hi All,
I was just wondering if anyone has come across using a 3rd party USB external HDD enclosure with a hard drive (mine is 500GB HDD). What I am trying to do is to format the HDD so both PC and MAC can use it but it will be mainly connected to my iMAC. I have tried by using PC to format the HDD to NTFS but MAC will not show the HDD on the desktop when I plug the USB to the back of the iMAC.
I have done some researches and it seems the only way to do make this possibe is to format it into FAT32. So I have tried to use FDisk to make the partition but it doesn't seems to support anything bigger than 120GB, now I am really stuck. If anyone knows any quick and painless solution, please spare me some advice.
Headache!!

Windows can use, but not format, large FAT32 partitions. Microsoft wants to discourage using FAT32 for portable storage (for marketing reasons).
The solution is to use Mac's Disk Utility to format the disk as FAT32 (misnamed MS-DOS in Disk Utility). The disk will then be read/write by both Mac and PC.
Also, it's worth pointing out that you can read and write NTFS disks using MacFUSE with the NTFS-3G plugin. Albeit, this is very awkward to do unless you've got some UNIX shell experience.

[SOLVED] External HDD not mounting at boot

So, I've got this USB external HDD which won't mount at boot time. I set it in /etc/fstab using its UUID and it works immediately after boot if I do
sudo mount -a
I had it before on a different machine, running Arch too, and never had this problem. How can I see what's going on at boot time? I usualy just start the computer remotely (wake on lan).
Last edited by RaisedFist (2010-10-21 11:22:46)

Couldn't it be caused by the external HDD not being ready yet when the system boot? Nowadays I rarely encounter these issues, but some years ago even certain internally connected drive would need a delay to get ready for boot. If so settings in BIOS has to be adjusted.
Just a quick guess.

Installation of Windows 7 via USB External HDD (Boot Camp Assistant)

How do I mount Windows 7 Ultimate disk image (.iso) onto my USB external HDD so that I can boot using that USB external HDD? I have tried reEFIt, but it doesn't work for me. It may be because I did something wrong. I would appreciate a comprehensive guide. Thanks.

i suspect you haven't prepared the USB drive as a boot volume.
You can absolutely do this. It is detailed on CNET in the following article: http://reviews.cnet.com/8301-31012_7-20020513-10355804.html

External USB-hdd not recognised by Finder if connected to Time Capsule

Hello!
I'd like to connect a small external harddrive (40 GB) to my Time Capsule (1 TB) via USB.
I've read on http://www.apple.com/timecapsule/wireless.html the followings:
"... +And if you want to share both a printer and an additional hard drive, you can. Just connect a USB hub to Time Capsule.+ ..."
While I've connected two printers to Time Capsule - so I already use a USB hub - I've tried with the external USB-harddrive, but it wasn't recognised neither by the Finder, nor by the DiskUtility-app. The external USB-harddrive appears not even if I connect it directly to the Time Capsule!
Restarting the Time Capsule / USB-hub / external USB-harddrive / my Mac doesn't change anything
The external USB-harddrive appears only in the AirPort-utility app (5.4.2) in "manual Config" - "Devices", but even here only as a possible archiving device for the internal Time Capsule harddrive.
The USB-harddrive itself is formated as Mac OS extended (journaled) and it works like it should on my iMac (3.06 GHz, Mac OS X 10.5.7).
Do you have any idea why the external USB-harddrive doesn't appear when connected to the Time Capsule?
Thanks!
Regards,
Vlad

Vlad, this might help...
*Accessing External Hard Disk*
Open a Finder window
Select the Time Capsule in the Sidebar on the left.
Click "Connect As..." in the upper right of the window.
Enter the Name of your Time Capsule & its' password (Note: NOT your own Username & password).
Check "Remember password in my Keychain."
You should now see a blue share folder with the name of your Time Capsule.
Any hard disks attached to the Time Capsule’s USB port will also appear here as blue share folders. To mount them on your desktop double-clicking their blue folders. If you had a separate password setup for those disks in Airport Utility then enter that password if asked. Otherwise, it should now mount on your desktop.
Let us know if this solves your issue. If, however, the drive is not showing up either on the Desktop or the Sidebar, you may still need to do the following...
*On Desktop*
In the Finder, go to the Finder menu and select "Preferences".
Click “General” in the toolbar.
Ensure that all the items under "Show these items on the desktop" are checked.
Close the preference window.
*In Finder SideBar*
In the Finder, go to the Finder menu and select "Preferences".
Click “SideBar” in the toolbar.
Ensure that all the items under "Devices" & “Shared” are checked.
Close the preference window.
Did this resolve the issue?
As for Disk Utility, bear in mind that DU won't "see" network attached storage devices unless they are already mounted on the Desktop. And even then they are sometimes not "seen" by DU. If you are going to do any work on a network attached storage device avoid attempting to do it wirelessly. Best to connect it directly to the Mac (USB/Firewire), or at the very least via ethernet.
Hope this helps. Cheers!

External USB Hard Drive Not Recognised / Seen

Hi,
I have a WP 250 GB External hard drive which was working fine until recently and now is not recognised by my 2007 Intel Macbook. When I plug in the hard drive, a light comes on solidly and it begins whirring. Then, it continues to whirr as if it was going to work, but the light starts flickering.
It is not visable as an external hard drive in finder. 'View Hard Disk' is switched on under Finder / Preferences. On System Profiler, when I click 'USB' fom the list on the left, the computer displays the circular "thinking about it" spinning thing, and system profiler freezes, and nothing else happens. The same thing happens with disk utility.
I tried plugging the hard drive into a windows computer, and it worked fine; all the files inside it were visable. It is formatted to my mac and I have successfully used the hard drive many times before. A logical next step would be to try it on another mac but I don't have access to one.
I have tried to to a PRAM reset, but couldn't do it, even following the instructions on the MAC website (turn off computer, turn on and hold the mac button, ctrl, p, and r simultaneously) it wouldn't do a PRAM reset.
I am not a computer expert, but I am not completely green either. Why is it that doing the simplest thing on a computer requires a minimum of a 4 year computer science degree or equivalent.... somebody please help me crack this, I am close to smashing the whole thing to pieces with a hammer (which would be satisfying but counterproductive and expensive...)
Thanks in advance for your replies

Did you allow Windows to upgrade the formatting on this drive from FAT to NTFS recently? You should be able to check the formatting on the volume from within Windows. It would also be worth trying to repair the drive under Windows if it allows you to.
Note that NTFS is not readable under OS 10.4.x without special software. NTFS is read-only but not writable under OS 10.5 and later.
If the volume isn't NTFS, and repairing it doesn't help, you may need to just backup the data and try to reformat it.

USB and external HDD not detected by OS X

Hello.
Since last few months, whenever I plugin a USB pen-drive or an external hard disk, it seems at first that the system has not detected the disk, since nothing shows up in the finder and there is no way to access the disk also. The disk connection is complete since the lights turn on immediately.
When I remove the disks from the port, I get a message that I should first eject it and then remove the disk, which is not possible because I CANT SEE THE DISK ANYWHERE.
Now I plugin the disk the second time and IT GETS DETECTED.
I have to do this with every external storage disk EVERY SINGLE TIME.
Someone please help me find a solution to this problem.
Thanks.
Sankalp

Hi James,
The USB hub will not function on a non-Apple branded monitor without connecting a USB cable from Type-B USB port on your monitor to one of your mac's Type A USB ports. The USB host bus should be beside your Display Port output on the monitor. Generally, a Type A to Type B USB cable will be included with your external monitor.
Hope that helps.
