USB stick won't mount on mac mini, it works perfectly on my macbook

Both of them are osx lion.
On the mini the led of the 256Mb USB stick (and still plenty of space!) gives short flashes every second, and won't mount on my desktop, in finder. It doesn't show up in disk utility.
The mac mini is the most recent server model. I tried USB ports on the back of the mac mini, and also on the connected thunderbolt display. Other memorysticks work well. Only this particular one doesn't work on the mini.
The memorystick works perfectly in my 2008 macbook pro. Plug it in, it mounts as it should do.
What can i do?

In Disk Utility, once you highlight a Drive or Partition, you'll see Verify Disk, (blue arrow), & if a drive you're not booted from then Repair Drive, (red arrow), will be an option also...
I'm thinking you may have to copy everything off it & see if you can Format it FAT32.

Usb stick doesn't mount on Mac, but does on Win

Hello all,
I've been looking for a solution for my issue allover, but it seems to be persistently difficult to find.
I got an unbranded 4gb pen drive formated as FAT32. The device works perfectly on Windows, but my Mac OS 10.8.4 doesn't recognize it.
I've tried to:
a) Look at the "Utilities Disk" and "Finder". Doesn't show up.
b) Format at any possible format with Windows (FAT32, exFAT, NTFS, even HFS+ using a software).
c) Use another usb stick in the same port. It works with any other pen drive.
d) Use the usb stick in another computer. Still, work only on Windows, not on Mac.
e) Use it with Windows. Works.
P.S.: I'm attaching a image of the mounted items. The two HFS are partitions of my external hard drive (disk1s2 and disk1s3) and the other is the Bootcamp partition (disk0s4).
Does anyone know what I could do to make the usb stick work on my Mac?
I'd appreciate any help on this matter.
Cheers!

OK, a SD/compact memory card type of thing used with cameras. The same solution/diagnosis still applies. Failing mounting the memory card directly in the MacBook, you could do it indirectly, via a cable that connects the camera or whatever it is used with, with the card in it, and the cable connected to your MacBook's USB port. It's a bit of a pain, but it's usually possible to do it that way.

I just purchased Apple USB SuperDrive and connected to my Mac mini 2012 but does not show anything on the screen. Not sure if its working.

I just purchased Apple USB SuperDrive and connected to my Mac mini late 2012 USB slot but nothing shows up on the screen.
I have OS X versus 10.10.3

The system bus and all connected products should appear in the system profile or in the
hardware part of About this Mac (more info) and if that does not, restart the computer with
the external Apple USB SuperDrive plugged in. •As a last resort, if nothing else, before a
return trip to be rid of the SuperDrive, you could try a system management controller reset.
The SMC reset is not a first choice, so I won't post a link to the support instruction page.
A new Apple USB SuperDrive should be seen as hardware in system information report.
Of course, an icon of disc media should appear once the disc is inserted into the drive, too.
Good luck & happy computing!

USB Audio output for a intel Mac Mini

Is there a USB Audio output device I can get for the Intel Mac Mini, that works in both Mac OS X and Windows XP Home?
I took my Mini apart to put in a hard drive, and now the sound sometimes doesn't work (Internal or External).

IPad Mini Won't Sync With Mac Mini (ios 8.1 OSX 10.6.8)

Problem : IPad Mini connects to iTunes OK, can be seen in iTunes and I can select which movies to sync to it etc. When I hit the "apply" button after making a change (ie deleting or adding a movie) the sync lasts just a second then the "sync" button remains greyed out, and I can't make them sync.

I'm having trouble connecting Brother DCP197c to Mac Mini - it worked before Yosemite

I'm having trouble connecting Brother DCP197c to Mac Mini - it worked before Yosemite.
I have downloaded drivers from Brother
I have tried searching for the printer once the drivers have been installed, but nothing...
Not sure what else to do - any helpful suggestions are welcome.
Thank you

I tried the Reset Printer option - it didn't work at first but then I decided to download the drivers again... and now all is fine and dandy.
Thanks for your help

Will the mac mini definitely work with a 50 hertz tv?

Just wondering if the mac mini will work with a 50 hertz tv

Yep - just go to the System Preferences and choose display and hit 'detect display' which will give you 1080x and other TV resolution options (assuming you have a modern LCD or similar).
You should then be able to select 50 or 60 hz.

External backup drive will not mount on new mac mini. still works fine on the old one. new one is running mavericks

I just bought new-to-me mac mini running OSX mavericks.
Trying to migrate from old mac mini using simpletech external hard drive.
It still mounts on my old mac mini (system 10.5) but will not mount or show up when I plug it in to the new mac mini running mavericks.
Any ideas?

What exactly shows in System Profiler>Hardware>USB for those drives?
Boot from the Install Disc & see if they show up, not grayed out in Disk Utility.
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (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.*
We were thinking along the same lines. While at home I dug up a firewire enclosure and put a bootable GUID formatted drive in it (that I had in one of the usb enclosures) and started her computer holding down the option key and then chose to boot from the external firewire. All usb drives are now mounting upon connection. I asume that her drive has bad sectors on it (even though the SMART status says it's OK) and is not loading all the drivers properly for USB to mount. I was suspicious from the beginning that the OS was corrupt when she first had me look at it. It was at that point that I booted it in target mode, connected to my Macbook Pro, and then CCC'd to a usb drive that I had. I then had a couple of difficulties installing the new OS. Should have known......
I am now going to put a new drive in it for her and she'll be up and running.
Thanks so much for your help and thoughts that got me thinking as well.

WD 3.0 external hard drive won't mount to Mac

I've had this Western Digital 3.0 external for some time and now it won't mount. I'm running Yosemite on my iMac. Full disclosure, I did drop the drive a day before it stopped being recognized on the Mac but it wasn't a hard drop and the external drive was running just fine immediately after the drop. I've seen some posts on here talking about WD external drives not working after updating to Mavericks but I didn't have that problem.
I've zapped the PRAM.
I've made sure it wasn't the cable - I have another 3.0 drive that mounted just fine using that same cable.
This WD external drive is self powered so it's not a power source issue.
I've tried updating the Firmware but since the drive isn't mounting, that did no good.
The USB port on the Mac is fine - plugged in another drive and other devices in that same port and they are all recognized and working fine.
Just to make sure, I tried using another port. No different result.
I tried the Option key on a restart to get to Disk Utilities but it's not seen there.
While the drive was working, I was pulling music from iTunes to my iPhone, just loading it up for a trip. I keep all of my music on this one WD external hard drive. I loaded up about 70 songs and intended to load dozens more. While pulling some songs over, things froze up. Wasn't able to do anything in iTunes or, as best I recall, anywhere else. Things just froze. I hard restarted the Mac - via the power button - and since, the external drive hasn't mounted.
About ready to try this possible solution as described in this discussion:
Your dead external hard drive is likely fine! Great hope for your 'faulty' external HD
Soooooooo . . . help would be appreciated!

Hello
Ihad EXACTLY the same thing happen to my WD hard drive... MINUS the dropping.
Was organising my iTunes and iPhoto library, kept crashing, over and over again, then the last time, i restarted and it won't mount.
Except not only is the WD hard drive not mounting, after the crash and restart of itunes etc neither is my Time Machine hard drive which is connected via a LAN cable.
Exactly the same scenario, all the ports work, all the cables are fine etc.
Just went BOOM - not happy and stopped working.
All my photos and music are on this one drive.
Did you manage to fix your issue?

External USB drive won't mount after 10.9.5 upgrade

Is anyone else reporting the following issue? Immediately after installing OS X update 10.9.5 (13F34) on 09/18, my external USB drive (IOMega 1GB OS X Extended FS) used for Time Machine would no longer mount and isn't recognized. When I look at the drives in finder, it is missing. However, it does show up under the USB Hi-Speed Bus device tree:

I have reinstalled the combined 10.9.5 OS upgrade, and verified that the drive works when connected to my other MB Pro (mid-2012 running Yosemite beta 3). There is no third party software that I'm aware of in use for this drive, as it's only for Time Machine backups.
Thanks

Is the drive's icon on the desktop (perhaps behind another icon, which is possible if Finder > View > Cleanup is enabled)?
If not, is the box Finder > Preferences > General > External Disks checked?
Is the drive listed in every Finder window's sidebar?
If not, is the box Finder > Preferences > Sidebar > External Disks checked?
Are Time Machine backups to the drive happening on schedule?
If not, does the drive appear in System Preferences > Time Machine > Select Disk?
Can you open /Volumes/Mac-Mini 2/Backups.backupdb using Finder > Go > Go to Folder...?
Does the drive appear in Disk Utility? Is it (or can it be) mounted there?
Have you tried to plug it in to a USB port on the Mini (not a hub) or into a different USB port on the Mini?
Have you tried this: shut down; unplug the drive; boot the Mac; after you have logged in and the Finder is done populating the desktop and menu bar, plug the drive in?

External USB drive won't mount without running Repair Disk

I have a Seagate external USB hard drive. It's a 1TB FreeAgent drive that's USB powered. I use this to share data across several computers. Every time I connect the drive to my MacBook Pro, it does not mount. If I try to mount it, I'm told to "try running first aid".
So, I run repair disk, and then it will mount. I just did this, and Repair Disk reported "The volume /dev/disk1s1 appears to be OK".
Any help on this matter would be appreciated. It is formated NTFS, and I have an NTFS driver installed, if that makes any difference.
Thank you!

USB stick won't load

I was sold the USB stick at the apple store when I asked about upgrading from 10.5.8 to Lion. The salesperson told me this was the way to do it in one step without having to buy snow leopard seperately. Was I misled? I won't install and tells me I need to install snow leopard which looks like an additional $30. I would have downloaded the cheaper copy online if that is the case. Is there not a way to load it straight from this stick without snow leopard? I only have Photoshop CS4 as an additional program and can reload that if needed.

I hope you can take it back for a refund. The salesperson was mistaken about being able to use it to go from 10.5 to 10.7. The Lion USB drive is licensed to be used only with Macs already running 10.6.

USB Stick Won't Appear on Desktop or Disk Utilities

Hi there,
One of my USB sticks doesn't seem to appear on my iMac. I have looked in disk utility and it doesn't appear there so I can't format it, and I have plugged it into another Mac and have had the same issue.
My external hard drive still appears and continues to back up using time machine, and I have tried the other USB ports in case one was faulty.
Has anyone come across this? Any tips?
Thanks a lot.

I have plugged it into another Mac and have had the same issue.
It is possible the stick has failed since you are having problems on 2 computers and not getting the correct response from what arthur suggested.
