Please remember there is no Iomega icon on the desktop until you mount a 250MB disk, just like the optical drive.

USB Flash Drive not mounting

I recently bought an 8GB USB flash drive, which came formatted FAT-32. The drive was put into a friend's Windoze laptop and had a couple GBs of jpeg and avi files transferred to it. I took the drive home and put it in my white MacBook (4GB RAM, Leopard 10.5.8) and it would not mount. I put it in my G4 MacMini; likewise, it wouldn't mount. I am assuming it also won't mount in all my older Macs with USB, either. I returned it to the Windoze laptop, and it ALSO wouldn't mount this time, except as one pulled the flash drive from the Windoze laptop, for a second a window with the flash drive's contents would flash on the desktop of the laptop. Originally, the flash drive was "properly" ejected from the Windoze laptop.
On the MacBook, both Disk Utility and DiskWarrior do not see the flash drive when it is in the USB port (either port). However, Apple System Profiler does recognize when it is plugged into the port. ASP returns the following information when the flash drive is in the high speed USB port:
"Flash Disk:
Product ID: 0x3234
Vendor ID: 0x1221
Version: 0.00
Serial Number: 10000000000003CF
Speed: Up to 480 Mb/sec
Manufacturer: USB2.0
Location ID: 0x24100000
Current Available (mA): 500
Current Required (mA): 100"
Anybody have any idea what is the cause of my problems with the flash Drive and how I can get the drive to mount? I don't think the problem is a function of my Apple hardware, as my USB ports on all my machines function with everything else USB which I have without problems. Thanks.

I know that, but I have USB in my older Macs, too, and besides, some of the most knowledgeable people are in these older forums!!
I've come to the conclusion that the drive may be defective, too, but I was just looking for some possible angle which I'd not already considered. I tried reformatting, but without the drive even being recognized, it isn't even possible to reformat. I can only get ASP to indicate that it is attached.
Thanks for your try!

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.

Usb flash drive not mounting when inserted (SOLVED)

Hi,
I am (now) using fvwm-crystal with rox as my file manager and when i insert a usb flash drive in to a usb port nothing happens. I check /media and nothing is there. Yes i do have hal started at boot.
I reinstalled arch with xfce4.

Well, there are the on-line manual pages:
man ivman
man IvmConfigActions.xml
man IvmConfigBase.xml
man IvmConfigConditions.xml
man IvmConfigProperties.xml
And there are examples in the default files (/etc/ivman/) provided with Ivman.
But that you probably already know. I'm not familiar with any other docs, except maybe tutorials on the net if you count them as docs

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 mounting til after restart

This weekend I put a new internal hdd in my Power Mac G5, and decided to use this opportunity to go ahead and put Leopard on one of my macs.
I'm finding that it doesn't mount some my USB External Hard Drives (3.5" externaly powered cases) unless I plug them in, and then restart the computer. (It also works just starting up if the G5 is off.) The drive needs to be turned on before the start up.
This is the case with an older IDE->USB 5 inch case, a brand new sata->USB 3.5 case (with the former g5 drive inside, and a sata->usb newertech bridge on the g5 drive. A bus powered 2.5" one mounted fine without the restart. I have not tried any flash drives.
I've tried the different USB ports on the G5 with no difference. I have not tried plugging it into a hub that's pre-connected (either powered or non).
They don't show up in Disk Utility during the time they don't mount. They do after the plugged-in restart, though. They also unmount then remount fine after the plugged in-restart.
The drives work just fine on my MBP (running Tiger). They worked just fine before the Leopard upgrade. If I boot into the Tiger partition on the G5, they work just fine.
I've seen references to other people having what sounds sort of like this problem in google searches but nothing exact, and those threads seem to get sidetracked with useless comments (like "Well, you should just use Firewire!" etc).
Has anyone experience this...and moreover, anyone found a fix.

Two things to check:
The drive must be formatted in Mac OS Extended (Journaled) or FAT 32
You almost always have to use a powered USB hub with the under powered port on the Time Capsule, even if the hard drive has its own power supply
Where are you expecting the drive to "show up"?

USB External Drive not mounting after use with Time Caplule

I have a 1TB external Lacie hard drive I have been using to store data via connection to my Time Capsule USB port.
I purchased a new HD to replace the Lacie and would like to use the Lacie as an external drive for my Macbook Pro.
Issue:
I erased all files on the Lacie before disconnecting it from the Time Capsule.
Connected the Lacie to my Macbook Pro via USB port.
Lacie disk spins, but never mounts - disk image never appears, disk just keeps spinning.
Ran Disk Utility. Lacie image shows up. Tryed to erase, but got an error that it wont mount.
Tryed to repare disk, but got the same message.
This also happens when I try to connect the Lacie to my iMac.
So, hooked it back up to Time Capsule. Disk shows up just fine.
What's going on???

Where does it show up - Finder or System Preferences/Time Capsule?
Try ejecting the drive, turning it off for awhile, restart the computer, and then restart the drive and plug it in.

SOLUTION - USB 3.0 External Drives Not Mounting on MBP Retinas - SOLUTION

So I have been having the same problem as everyone else who has issues with USB 3 external hard drives not mounting on their MBP Retinas. My friend told me to try unplugging the USB cord and plugging it back in instantly (like in half a second, so as to not let the power turn off on the drive). I had my doubts but then I tried it just now, and MY DRIVE MOUNTED.
GO TRY IT AND SEE IF IT WORKS FOR YOU!
UPDATE: I am using a powered external drive (Seagate Backup Pro 3TB). Not sure if this will work with bus powered drives, but I think it might, as my friend might have been using a bus powered drive.
Also, I just bought two Hitachi TOURO 750GB bus powered portable drives (7200rpm/USB 3.0) and they mounted perfectly without problem as soon as I plugged it in for the first time.

Did you unplug the USB cable from the computer or from the external drive? This fix has been posted here previously but it was reported that the cable had to be unplugged from the device, not the computer. If the cable was unplugged from the computer instead, the fix didn't work.

Hard Drives Not Mounting - Help!

Hello,
This is my first post, so please forgive me if I leave anything out....
I recently had to replace my hard drive. Got it all going, then I noticed when I went to put a music CD in, that it would not show up. I tried others with no luck....then I put in a cd with data, and it showed up on the desktop....
While trying to mess around, I made my 2 LaCie external hard drives go away! I have tried checking cables, and they come on when the computer does, they don't show up in system profiler....
Please let me know what information you might need to help me diagnose these problems....my computer has been so good to me, I want it back up and running...
Powerbook G4 Ti 667 MHz Mac OS X (10.3.9) 512 Ram

Hi, mcholley, and welcome to Apple Discussions.
I can't suggest any remedy for your optical drive not reading audio CDs but having no trouble with data CDs, except to say it's apparently a software problem, not hardware-based.
After replacing your hard drive, did you reinstall your operating system from scratch on it, or did you restore your OS from a backup you had made?
The disappearance of your external drives (are they USB or FireWire?) may be power-related. Are they externally powered, or are you powering them from the USB or FireWire bus? If they're bus-powered, are you connecting both of them at once? That won't work: together they demand more power from the bus than it can supply, and while they may spin, they won't mount. Connect only one of them at a time. Is either of them detected by Apple System Profiler when just one is connected to the Powerbook? Does it mount on the desktop then?
If you've been able to connect both drives to the Powerbook at the same time in the past, and both have mounted OK, then there's been some hardware change recently, other than your hard drive replacement, that has caused the loss of external drive detection. Is it possible that during your recent operations you've turned off one or both of the external drives, or disconnected it/them from the Powerbook, without dismounting it from the desktop first? Depending on what, if anything, the drive was doing at the time, that can make a FireWire drive unmountable and all the data on it inaccessible. In that case it may be necessary to erase and reformat the drive. I don't know whether the same is true of USB drives.
Do you have another Mac to which you can connect the drives, to see whether they show up on it? If they do, you might have to consider the possibility that the port(s) to which you've been connecting them on your Powerbook is bad.

External Hard Drives not Mounting after Yosemite Upgrade

I've just upgraded to Yosemite, and none of my external (USB) hard drives are mounting (they don't even appear in Disk Utility).
Any ideas?

MacBook Pro 2009. 250 SD, HD 8Gb Ram.
I have had this issue for about a year...with no resolve!
Apple and the User community have not been able to solve issue.
I have had to work around it since the Oct 2013 Mavericks upgrade which “killed” (rendered unmountable) both my USB and Optical drives.
Hundreds of replies and remedies have not corrected my issue. Hundreds of replies stating that if there was a global issue it would of been fixed by Apple, not true. And dismissive replies stating that there must be a hardware issue are very discouraging.
So now, hoping to help the voiceless masses, I'm forced to share my experience.
As I stated, I have been having the issue since one of the Mavericks upgrades. The upgrade rendered externally attached drives unmountable...They are all seen in Disk Utility. They are just not mountable. Regardless of the flavor of the disk format, either Mac or PC, they are found, seen and refuse to mount. I can see them using Terminal commands, I can see them in System Report. I can reset all the memory I want...turn it off, reset, sleep, turn on, restart...NOPE...And the optical drive takes in disks but ejects them after an attempted mounting. Keep in mind, there are no physical issues with either USB or optical drives.
So now...I have had enough and need to correct the issue or buy a new equipment - starting to get into software development and need working equipment!!!
For the past month, I have been visiting the Apple store to assist in my issues...Back Story: I'm an IT Field Tech for the largest department store in the country and I have the good fortune of dropping in the Apple store anytime I want...The Geniuses booted the MB with a bootable image of Mavericks, and the USB and Optical drives WORKED fine...So, after I had stumped the Geniuses with my problems, we agreed that we would attempt to format and re-image the MacBook...Fine, do it, it's backed-up, how you ask? - Via my wireless My Book Live 3T drive, which only took 24 hours to backup, AKA Time Machine!
Great news! The re-image of Mavericks proved to work! I WAS able to mount external drives attached! How is that possible? Don't know, don't care! It just worked! So happy!
But wait! I then took the laptop home. Connected to my WiFi, to update Mavericks to the latest version...Good so far! Then it came time for a Time Machine restore, AKA Migration Assistance restore...So, I proceeded to migrate data back to my MB via wireless drive, good so far, booted in Migration Assistant, and I chose to restore everything except the network files, thinking that may be an issue...22 Hours later, the MB migrated without issue...all apps and personal files had migrated! YAY!
BUT NOW THE USB AND OPTICAL DRIVES FAILED TO MOUNT!!!
Great now what? I know, I will just re-image and start again...WAIT, I don't have a Mavericks Install Disk, no problem, I will just create a bootable USB drive with the Mavericks Install Image I downloaded onto my MB this month...NO YOU CANNOT, because you have no use of the USB drives!...And, Apple stopped making OS CDs back in 2009...Oh, and that wouldn't of done me any good, because the optical dive was unusable, anyway!
SO, back to the Apple store with my head hanging! At this point, Yosemite came out the previous Thursday, so no more Mavericks images, great! Perhaps the new OS will alleviate my nightmare!!!!...So, they re-imaged my Mac with Mavericks, drives worked again! SO, I took my MB home and attempted to download the new OS, Yosemite...which only took 2 days due to the amount of traffic on Apple's servers!...Anyway, Yosemite finally installed without out issue! Drives still worked! And so, I shutdown and restarted the system...No issues, USB and optical drives worked beautifully! Yay, Yosemite!...Fixed all my troubles!!!...Not so fast...
And so, I, again, attempted to do a Time Machine restore, via WiFi, this time it took 24 hours to restore...AND it worked! All apps and personal files transferred without issue, So happy! Put the laptop in Sleep and left it home and went to work! Came back from work, tested the system without issues. Rebooted...USB and Optical drive are NOT MOUNTABLE!
So now, what is the file that the restore keeps pushing to my MB that kills the USB and optical drives?
I would just stop restoring from a Time Machine backup, but the only way to get into the TM image is to use Migration Assistant. I cannot view the date in time of the image in TM's Star Wars time line. So, I'm forced to back up everything from the image in Migration Assistance. Not sure that it being an encrypted image has anything to do with it...
...Regardless, what is being “restored” to the MB that continues to configure the OS in such a way that makes all external drives unmountable...keep in mind, my external keyboard, hub and mouse are usable via USB.

How to launch Apple Hardware Test from a USB optical drive?

Hi all!
First off, and before you guys starting proposing solutions I can't implement, I don't, repeat DON'T have a Firewire optical drive, nor am I going to buy one: I recently had to buy a USB LG optical drive to compensate for my SuperDrive going AWOL on me. I used said drive to reinstall OSX about a month ago, so this LG drive works just fine, thank you.
The thing is, I'd like to conduct an Apple Hardware Test, and I know you have to boot from OSX CD n°1 (in my case) to do that. Alas, since I can't boot from the CD in my SuperDrive by keeping the D key down, all I have is this LG thingy, and I wonder how I can conduct my hardware test with a USB optical drive.
I'll sum it up for you:
1) My SuperDrive isn't working, stopped working about the same time I installed this EFIng (guffaw, guffaw) Security Update 2009-001;
2) I don't have a Firewire optical drive;
3) All I have is a USB optical drive and MacOS X CDs.
4) Booting with the OSX CD in my USB optical drive and keeping D, C or alt keys didn't help.
I read in another forum that you could somehow copy the content of the OSX CD on a flash drive, then boot from the flash drive and conduct an AHT, but I'm not sure how it can be done.

Hi!
Looks like we posted at exactly the same time, Glynn! LOL
Anyway, I did just what you said, drag'n'drop and all. The problem is, when I boot from the USB hard drive, it's exactly as if I were booting from the CD: first I'm asked to choose a language, then the install screen appears, and I can either reinstall on my startup disk from the USB hard drive (that's kinda cool, but I don't think I leave in on my USB hard drive, which can only content 40Gb, because I've almost 25Gb worth of data to retransfer soon...
So, in a nutshell, I couldn't find Apple Hardware Test anywhere. I even explored the CD content, but there are so many files...
What's my best option now? Could AppleJack help me here? Can I install AHT on my startup disk and boot on it using a special set of keys?
Almost time to go to work. A 5 minute walk, though...

i guess i forgot to mention in my original post that registry limits were not the problem...they dont even exist...as i did mention, i tried different fixes which included

as well as manually checking the registry and every other file mentionable my friend has not been able to find her original disk yet, so that remains untried as of date....and BTW, an usb external cd/dvd drive works just fine....but we dont want a patch, we would like to fix the problem and use the internal drive the laptop came with....

Upgrading Xserve G5 using USB Optical Drive/ Target Disk Mode

Hello Everyone!
I am trying to update my Xserve G5 that is currently running 10.3 (Panther) to 10.5 (Leopard). I have tried multiple methods and cannot seem to get it to work.
I have tried to:
Use a USB Optical Drive - I tried using a USB optical drive because the Xserve G5 has a CD drive not a superdrive. It recognizes the Leopard Installation DVD as it pops up on the desktop. I open the installation and click the restart button, but it restarts again and goes to my desktop as if I just turned on the Mac. I have tried doing this in Safe Mode (Holding down Shift on Start Up) and trying to select it from volumes (Holding down Option on Start Up). These two do not work.   I believe it is because I am using a USB optical drive and that it wont recognize the drive unless you are logged on in the OS. Could this be it?
Use FireWire Target Disk Mode - I also tried to use target disk mode by hooking up my Xserve to my MacBook Pro 2009. Everything work fine. I put the Xserve into target disk mode by holding down T on start up and it goes into target disk mode. It pops up on my MacBook Pro desktop as a FireWire external device (I can access all of my files on the Xserve hard drive). My only problem is that I do not know how to run the installation disk of Leopard off of my MacBook Pro so it installs it on my Xserve.
Any Suggestions or Ideas would be greatly appreciated.
Thank You
- Ryan

So what should I do since reformatting the HDD through disk utlity on the Xserve is not an option
Why not???
Boot th xSeve using alt key from Install Disc in MBP, then...
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
      *Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
   3. Click the Erase tab.
   4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
   5. Select your Mac OS X volume.
   6. Highlight the drive, select Partition Tab, then Format type... MacOS Extended Journalled, APM Partition.
Quit DU which puts you back to the Installer... Install.

None of my usb flash drives are mounting

OS X 10.6.8 - None of my usb flash drives are mounting. They don't show up in disk utility either. System proflier does show the flash drives. I've run disk warrior and the flash drives show there as well. I've tried all of the usb outlets with several flash drives and none of them show up. I can use the same usb outlets to use my wireless keyboard, mouse and also my ipad.
Finders preferences are all checked to show items on desktop.
One of my flash drives I tried several times and finally got this screen message. "System extension cannot be used The system extension "/System/Library/Extension/IOStorageFamily.Kext" was installed improperly and cannot be used. Please try reinstalling it, or contact the product's vendor for an update. Non of my other 6 flash drives mount and they do not receive any screen message.
I've also run repair disk permissions several times and the it says permissions repaired so I run it again and the same issued it said it was repaired, it lists again. I've done this several times with the same results.

Hello
from that
"System extension cannot be used The system extension "/System/Library/Extension/IOStorageFamily.Kext" was installed improperly and cannot be used"
try this
- boot from your original system disc
- plug one of your usb flash drives
- see if installer software could use usb flash drives as target for install
( testing your usb flash drive from a know good system software )
- DO not perform install on flash drive , just need to know if flash is usable
if it could , re-install your system or if it was updated from a previous version re-install 10.6.8 combo update
http://support.apple.com/kb/DL1399
checking for any missing update ?
