USB thumb drives not showing up on desktop.

After updating to 10.4.7 last week, when I insert a USB drive it does not show up on the desktop or in the finder. When I open System profiler and click on USB it shows up there but I have no way to mount the drives.
Is this something that happened to anyone else or am I alone in this?
When I plug in a USB mouse into the ports it works fine so the USB is working, just not mounting the drives. I am able to mount the drives in other macs I have here.

You might check your Finder preferences and make sure
you're allowing removeable to appear on the Desktop.
Nope checked that and the boxes are all checked.
Tried plugging my iPod in using the USB cable and still does not show up. Does not even show up in iTunes.
Also tried plugging in a firewire drive and that does not mount either. And the iPod also does not mount using firewire.
This is really getting frustrating!!!
Weird thing is it shows up under firewire & USB in system profiler.

USB External drive not showing in Finder, or on Desktop

I have two USB external drives from the same manufacturer. One is for regular storage, the second is for Time Machine and movies.
The first one shows everywhere, on the desktop, in finder and in Disk Utility.
The second drive shows in Disk Utility only. However, it is functioning fine with Time Machine. So it is mounted. I have tried several repairs, and it reports no fault found. So it is certainly functioning correctly, but a setting or error in the operating system is not allowing it to be viewed in finder, or on the desktop.
Any suggestions.

Correction: Title should be Firewire External drive not showing in Finder, or on Desktop.

Hard drive not showing up on desktop

My hard drive is not showing up on desktop. Hardisc repair says drive is not formatted yet would not format drive or failed after initial attempt. I did put the same drive into USB external case and then it showed up on desktop. I then was able to format disc and install OS 9.2 onto disc but when I reinserted disc into Lombard (Powerbook G3 M5343) it was back to not appearing and identifying disc as not formatted.
When I turn on -getting a prompt that says built in memory test says there is something wrong with memory cashe could this have something to do with problem?
I don't think there is a problem with Motherboard as I just replaced it. I also don't think it is the drive cable as it identifies drive and also I have a "spare-parts" Lombard with a defective motherboard and I tried attaching drive with that drive cable and still had the same problem. Unless both drive ribbons are defective -I assume not...but maybe that could be the problem?
Any ideas?

Richard,
You do have a failure of the backside L2 cache, a common problem on the Lombard. This memory is soldered to the microprocessor card and the only fix is a replacement card.
http://docs.info.apple.com/article.html?artnum=51159
I don't know if the failed L2 cache memory would cause a problem with the HD on the internal IDE bus controller; it apparently does not via the USB bus.
Generally, users who have the failed L2 cache do not have a successful startup unless they reset the power manager. Try this: With the Lombard turned off, reset the power manager and see if it will start up to the internal HD. If no success, shut down, insert your OS 9.2 CD, reset the power manager, and see if the HD appears on the desktop after booting to the CD.

External drive not showing up on desktop

I have an external hard drive (2T Newertech ministack). We had a power outage the other day. Even though the drive is on it no longer appears on the desktop. I went to Disk Utility and see if it could be repaired but the drive is not even showing up there. Does this mean the ministack was fried by the outage or is there another way I can save it? And yes, the finder preferences are on for external drives to show up on desktop.

It's not likely it would be fried if it's connected to a UPS because then it would not lose power and crash. Have you tried disconnecting the device from the computer, rebooting the computer, then reconnecting the device?
Since you have another Mac try directly connecting the device to it and using Disk Utility to repair the drive. Then give it a try on the other computer.

USB thumb drive not working

I borrowed a friend's USB thumb/flash drive that had been used on a Windows PC to store important data. I downloaded some applications (Mac upgrades) onto the drive using a PC, and then successfully loaded them onto my G5. I safetly removed the thumb drive and now it doesn't work in either a PC or my Mac. Can anyone help retrieve this data using a PC or Mac? I'm sure it's a formatting issue but can't understand why my Mac no longer reads it.
On the Mac, if plugged into the keyboard, it gives the warning that it's drawing too much power. If I plug it into the back of the Mac, nothing shows on the desktop, even after a long period of time. The PC gives an oddball error - it's not recognizing the format.

Use a prepaid iTunes card if you haven't got a card

USB thumb drive not recognized on nc6120 laptop

I had Windows XP Professional on my NC6120 Compaq laptop. Due to Microsoft saying it was an illegal copy I had to get a different OS. I purchased a Dell Windows 7 Professional and loaded it via the different prompts. Once loaded I had no sound, no mouse, no USB operative. I fiddle fooled around in spite of these assinine sites that say they have the driver you need as though they are legite and all I got was crap loaded that I did not want or ask for. After many hours of trying I finally got some sound recognigition, and the mouse to work. I still have some graphics problems and script problems along with the fact that the computer does not recognize a thumb drive in any of the USB ports. I have tried everything that I could find on the internet and HP, Intell etc and I am at a loss as what to do.
I am not a fan of Microsoft forcing me to upgrade or because of no support to XP anymore but like everyone else I am held hostage to this monopoly.
Can any one help to at least get the USB's to recognize an "E" drive using a thumb drive. Is it possible that this Compaq NC6120 laptop doesn't have the gears to run Windows Professional?
Please help.

Hi:
W7 should work on your model by using some of the Vista drivers from your notebook's support and driver page.
I have no idea why the usb ports aren't working.
Suggest you reinstall W7 and do the following...
1. Install the Intel chipset driver first and reboot.
https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=20019&lang=eng&ProdId=816
2. Manually install the Vista graphics driver as follows...DL and run this file. You will get an unsupported operating system error.
http://h20564.www2.hp.com/hpsc/swd/public/detail?sp4ts.oid=447347&swItemId=ob_47264_1&swEnvOid=2094
Go to the device manager and click to expand the Display Adapters category. Click on the standard vga adapter.
Click on the driver tab. Click on update driver. Select the Browse my computer for driver software option and browse to the driver folder that was created when you ran the file. That folder will be located in C:\SWSetup\sp34749.
Make sure the Include Subfolders box is checked and the driver should install. Then reboot.
Audio: Be connected to the internet. Go to the device manager and click on the multimedia audio controller needing drivers. Click on the driver tab. Click on Update driver. Select the automatic search and after a few minutes, Windows update should find, download and install the audio driver.
Wireless: If your notebook has the Intel Pro 2200 B/G, manually install the Vista Intel wireless driver like you did the graphics driver.
Card reader: Use the vista driver from the nc6400.
Wireless assistant. Use the W7 driver from the 6910p
Quick Launch Buttons: Use the W7 driver from the 6910p.
Touchpad: Use the W7 driver from the 6910p.
If you need any other drivers, please let me know.
Oh, and if you don't like all the Dell stuff showing up on your PC, just download this plain W7 Pro 32 bit SP1 ISO file directly from Microsoft, and use the Dell W7 Pro product key on it.
http://msft.digitalrivercontent.net/win/X17-24280.iso Windows 7 Professional x86 English
Then use this tool to transfer the ISO file to a 4 GB USB flash drive or DVD.
The tool will also make the media bootable.

External USB Hard Drive not showing up on Time Capsule

Hi all,
I have a 500 Gb Time Capsule that used to be able to detect my external USB hard drives. I had to store my things for a while and have just started using the Time Capsule again. The TC works fine, however, the same USB external hard drives I used to connect to the TC are not showing up anymore :s They show up on the desktop when I connect them directly to my MacBook via USB. I have been through most of the file sharing options in Airport Utility and System Preferences but have not been able to solve this. I can't think of any settings that would have changed from when they were showing up in the past. Any help would be greatly appreciated. Thx

yosemite won't work with ntfs drives for some reason, i've had the same issue with my toshiba. i thought ok lemme buy another one, and transfer it over maybe it's a driver issue which i've tried over and over, apple support can't figure it out.
here's a simple fix, but the problem is i have an external where all my photography and video files are stored, so i can't access them right now and it's making my life ****.
http://guides.macrumors.com/Formatting_an_External_Device
that does work and make the drive mountable now, but problem being i can't obviously reformat the old drive and lose everything. once the new drive is formatted for mac i can't plug it into a pc to transfer the files from. which is the only problem now. but formatting the drive for mac only DOES work. but you're just screwed and not able to use it ntfs. hope the link helps SOME people.

USB Thumb Drive Not Mounting With Mavericks

I have several Thumb drives (FAT32) that no longer mount on my iMac running Mavericks.
The thumb drives do not show up in finder nor do they show up in disc utilities.
The USB bus still seems to work since other USB devices seem to connect to it, but none
of the thumb drives do. I have done an SMC and PRAM reset with no luck. I do not have
TUXERA nor NTFS-3G so nothing their to disable.
I do have a Mac Mini running Mountain Lion and all thumb drives do work with that.
Out of ideas here.

But given that other USB devices work here — what sorts of other USB devices?
I have 2 external hard drives that work on the very same USB port and an external blu-ray drive as well.
Are there any add-on anti-virus or anti-malware "tools" installed?
None. Never have.
To check the USB bus, remove all hubs and all other external USB devices from this Mac, reboot, connect one of the thumb drives directly to the Mac, and try again.
Everything re-connected except for the thumb drives. External hard drive and Blu-ray drives popped right up but no USB flash drives.
Try a different and newly-created login, and see if the flash drives work there.
I used the Guest login and the same thing, everything works except the Thumb drives.
To check the local OS X installation, see if booting this Mac from the recovery partition (if one is present)
None is present.
or booted from another (external) OS X disk allows access to the thumb drives.
I have en extern HD that is blank, but I do not know how to install Mavericks on it then run it.
Is there anything in common among these failing USB disks? Same brand and model? Or a mixture of different thumb drives?
They are all FAT32, other than that no I have Cruzer, Kingston and PNY brands. 2GB 4GB and 16GB.
Are the OS X systems involved both similar configurations, or are they very different versions?
Mac Mini is Mountain Lion and has no issues with the thumb drive.
Intel iMac is Mavericks and my Mac Book Pro is Mavericks. Neither one of them can mount my USB sticks.
Thanks for your complete reply, you had some items that I did not try but unfortunately it did not help yet.

Some External Drives not showing up on Desktop

I have 3 external drives hooked up to my Macbook for backup; a 120 GB Firewire external hard drive (Mac formatted), an 80 GB USB 2 external hard drive (Dos formatted), and a 256 MB Thumb Drive (Mac formatted).
Here's the problem. Sometimes after a restart all 3 drives show on the Desktop. Other times after a restart, the 120 GB and the 80 GB will show on the desktop. The 256 MB is nowhere to be seen and thus unusable for backup. And other times after a restart, the 120 GB and the 256 MB will show but the 80 GB is nowhere in sight and thus unusable.
How can I get all 3 drives to always show up on the desktop after restarts?

Hi Alan,
Have you shut down your Mac and disconnected your firewire cables from both ends and let it sit about ten minutes then reconnect and try. Also, it is important to disconnect the AC power to your Mac, to reset the FireWire port(s).

USB thumb drive not mounting... hardware or software problem?

I have two systems I'm working with. The first is a MacBook, running 10.5.6 (also Parallels 4 for WinXP). I have no problems here.
The problematic system is a MacPro, running 10.5.6 (and Parallels 4 for WinXP).
Symptoms:
All USB ports function (sort of). I can plug my keyboard in to any port and they work. If I plug a thumb drive in (to any port), it periodically flashes, but never mounts, nor is it visible in Disk Utility or System Profiler.
If I start Parallels with the thumb drive inserted. It asks me what I want to do with the device, and I can tell it to mount on the mac, and it does. If Parallels is already started, then I insert the thumb drive, nothing (Mac OS or Parallels) notices it was inserted.
If I boot Windows directly, then insert the thumb drive, it tells me the port is not a high-speed port, but will still mount the device.
Finally, again, I have no problems with this thumb drive on my MacBook.

Roger
This may be sorted out in the Preferences for Parallel. In the configuration editor>usb option>connection options.
With parallels running does it see the usb in the menu under devices when you plug it in?

USB Hard Drive not showing up in AirPort Utility

I have been using this AirPort Extreme for over two years now and it's been working fine. I finally decided to buy a self-powered USB hard drive so I can share it over the network. However, after I unpacked the hard drive, connected it to my Mac and reformatted it to HFS+ Journaled and GUID. I plugged the hard drive into my AirPort Extreme's USB port and waited. I looked in my AirPort Utility and saw nothing in the disk list.
I spent hours searching online and discovered that I am not alone in this problem, although solutions are rare. I did try one solution where I hooked up the USB hard drive to a powered USB hub and the hub into AirPort Extreme. It actually worked once and after I rebooted everything, even though the hard drive still showed up in the disk list, no computers can connect to it. Although if I connect the hard drive directly to a Mac, it would still work perfectly.
Having a USB hub is not a long term solution not that it's working anymore anyway. I would appreciate any suggestions you may have, thanks!

Thanks for the response. However, I'm not sure what you mean.
So far my experience is far from "Just connect the external hard drive to the USB port on the back of your AirPort Extreme and — voilà".
did you read the support article Daddy linked ? it clearly says

One of My Hard Drives not showing up ion desktop

Hi
I've got one internal hard drive that will just not show up on the desktop or finder windows I can see it in disk utilities and everything is ok it was working no problems yesterday but since I have had to do a reformatting of my system disk and reinstall leopard and then snow leopard as my system hard had been case sensitive formatted which was causing some trouble with some software not being able to be installed, so after a complete fresh install I now cannot see one of the 3 hard drive that is in my Mac, any ideasTTFN
Subcoustic

if you can see it in spotlight then you should be able to use the go menu. I suspect you are entering the path incorrectly. the drive might have a hidden flag. run the following terminal command
sudo chflags 0 /volumes/*
you'll have to enter your admin password (which you won't see). that's normal. see if the drive shows up after that.

External Hard Drive/Not Showing Up on Desktop

I have a G4, running OS X 10.2.8 and recently my kids deleted some important data. So--we bought an external hard drive (WD MyBook 160 GB Essential Edition, which says on the box that it runs 10.2.8 and higher).
We took the external hard drive and the computer to a reputable repair place, the guy there took the hard drive out and using a G6 system, restored what he could to the external hard drive.
We bring it home, plug it in, and the computer is not reading the new external hard drive. I did check in disk utility, and it shows up as a greyed out item on the disk utility.
The external hard drive does show up when hooked up to my husband's office PC.
Any ideas as to why this is happening and how to correct it?
Thanks, Ruth

OK, I figured it out (in case anyone else needs to know) with this information from the Western Digital site:
Macintosh Operating System 10.3.x or earlier will only recognize FAT32 partitions that are smaller than 128-gigabytes. Multiple FAT32 partitions smaller than 128-gigabytes will need to be created in order for Macintosh Operating System 10.3.x or earlier to recognize the partitions. You will need to use a Windows based computer to create FAT32 partitions, as Macintosh does not have the ability to create them.
Macintosh Operating System 10.4.x or later can recognize FAT32 partitions over 128-gigabytes.

USB Flash drive not showing on DT

Hi folks,
I received a USB flash drive with 2 GB capacity made by Super Talent (www.supertalent.com- look under Aluminum flash drives).
Upon plugging it into the G5's USB port (i've tried them all) I get a "Cannot recognize- Initialize/Ignore/Eject" message. Clicking Initialize brings up Disk Utility which sees the drive with a capacity of..wait for it..2 Terabytes! Here's DU's info:
Name : SKYMEDI USB Drive Media
Type : Disk
Disk Identifier : disk1
Media Name : SKYMEDI USB Drive Media
Media Type : Generic
Connection Bus : USB
Connection Type : External
USB Serial Number : 03
Writable : Yes
Ejectable : Yes
Mac OS 9 Drivers Installed : No
Location : External
Total Capacity : 2.0 TB (2,199,023,255,552 Bytes)
S.M.A.R.T. Status : Not Supported
Disk Number : 1
Partition Number : 0
Selecting HFS+ (journaled or not) or MS-DOS then clicking Erase gives me a spinning beach ball requiring me to Force Quit DU.
My config: G5 DP 2.0, 1 GB ram, 10.4.6
Any thoughts?
G5B DP2.0 & iBook366SE Mac OS X (10.4.6) Alu 20-in Display

hey there scan,
I gave the drive to a friend who has an iMac. Samething occurs: drive does not mount, DU erroneously reports 2 TB capacity and coughs up the beachball seconds after clicking on Erase to format it. He's on 10.3.9 while I'm on 10.4.6.
All the ports on my G5 are in working order as i use printer/scanner and iPod w/o problem.
Think the drive is going back.
