- - Tiny disk usb pen drive not mounting after.. (http://hintsforums.macworld.com/showthread.php?t=36578)

....a last ditch suggestion...

Perhaps reformatting (from the PC, of course) as FAT32 might put everything back to 'stock' and then it might mount from the Mac (again).

Pen Drive Problem

Scot I have had similar problems - use a pen drive in a PC and it does not show up on the desktop.

I have not managed a permanent fix, but I have always manged to get it to mount somehow. Try opening Volumes from terminal; this can force it to mount. Have a look at disk utility again - the pen drive may not show at the first attempt.

Does your pen drive have partitions? The one I use has a 1.44MB partition that does not show when used on a pc, but mounts on the mac desktop. I now know to always eject this first.

Finally, use safe eject on the pc. I know nobody but nobody uses this - except me as it does reduce the chance of a problem.

@macmath: Yeah some one at my uni suggested this. I mite try it and see if it works, no harm in trying hey.

@Doug955: I think some of the pen drive is partitioned for the PC drivers. Can i ask what the command is in terminal to open volumes and force mount it? And if i get it working again I'm not going to use it on a PC ever again!

Terminal Command

Scot I have used two approaches:

First: in terminal type cd /volumes Then type ls Hopefully your pen drive will be listed; if so you can type open xxxx (name of the volume).

Second approach (if above does not work): in terminal type cd / Then type open volumes

No guarantees, all you are trying to do is force the system to open a folder containing your drive's contents, or a folder containing your drive.

I have just checked the formatting of my pen drive and it is FAT16. Whether this is a cause I do not know.

How old is the device and what capacity does it have ?

its 128MB and its about 1 year old.

Hello there! Forum newbie here, found this forum after a google search trying to resolve a problem with an mp3/thumbdrive I'd bought my dad.
It's not liking his Mac Mini!

Here's what I get from System profiler..

Code:

MP3 Player:



  Version:    10.01

  Bus Power (mA):    100

  Speed:    Up to 12 Mb/sec

  Manufacturer:    Generic

  Product ID:    0x821c

  Serial Number:    23DE909708450B06

  Vendor ID:    0x066f

...and here's what I get from the console, thanks the the info a few posts up.

It's an Aigo A208 1Gb MP3/mass storage thumbdrive thing, works fine on a pc, website says it works fine with Mac OSX without a driver. A smaller similar device of same type works fine.
