USB flash drive not recognized by Macbook Pro

I bought two 4GB PNY Attache jump drives and, when I plug them into my 2007 MacBook Pro, neither show up in Finder. Strangely, they work just fine in my old 2001 iBook, so I know the problem is with my computer.

Any suggestions?

    Thanks for the advice, Josh. I checked my USB connections as you suggested and found that my computer does recognize the flash drive. Unfortunately, I couldn't go much further with your advice as I'm on a Mac, not a PC, and don't have a bios setup utility.

    However, I ran Disk Utility and re-formatted the jump drive from MS-DOS (FAT) to Mac OS Extended (Journaled) and now it works just fine.

    Ok, I'm a technology idiot. Since most of the world runs on PCs, my Mac-formatted flash drive is pretty useless.

    If I reformat it back to MS-DOS (FAT), how can I tweak my Macbook's settings to read it? I tried to follow your advice, but Macs don't have a BIOS setup utility.

    Can you please translate your instructions to Mac?

    Thanks!

Just bought a 4gb attache, plugged it into the usb on macbook pro and nothing happens


You can try going to the Disk Utility (which is under Applications > Utilities > Disk Utility), selecting the drive (if it appears) and click "Mount". If it doesn't show up in the Disk utility, then the device may not be connected properly, the USB port may not be functioning, or the device may be malfunctioning. You may try reformatting the drive with the Disk Utility if it is blank and you are just using it for the first time.

NEED DRIVER FOR PNY 8GB USB ATTACHE


If you're using the drive on a PC with Windows XP or Windows Vista, you don't need a driver - just plug it into the PC and Windows will recognize it and install USB drivers automatically.

4GB Attache flash drive says it's locked.


Plug in the stick. wait for it to come up on the desktop then click on it once. (do not open it).
From the file menu select "Get Info"
In the panel that opens up you will see a row of coloured squares. Underneath is a checkbox marked "Locked"
Is it empty or ticked?
If it's ticked, untick and see what happens in disk utility. If it's not ticked that then would appear to be a problem with the stick.
For what it's worth, I did a google on this stick and found that there are numerous posts about it becoming read only on Vista, so it may well be a problem with the manufacturer.
