Think of it as being a hard drive - because that's how your Mac sees it.

You need to decide if you'll be using it on a PC or on a Mac.

If its a Mac that you want to use it on, then you need to format it as a Mac drive, and then your Mac will be able to see it.

Regardless of what format the flash drive is using, your Mac should be able to "see" it. Have you tried using Disk Utility from Utilities to see if the HP flash drive shows up there?

If it's a 32 GB flash drive it's likely formatted as FAT-32, possibly NTFS. But either way your Mac should be able to see it. Make sure you try plugging it into every USB port on the Mac in case one of the ports is not working.

A close friend of mine got an HP Flash drive and had the same issues with it. Took it back and purchased a San Disk at my recommendation and it worked perfectly on his Macs and Windows machines. Not sure what is up, but figured I would post this just in case.

I'm having the same problem with an 8G HP flash drive on a Mac. Plugged it in for the first time last night and it appeared under Devices in Finder. Copied a bunch of files to it (Word docs and Excel spreadsheets) now I cannot access the drive at all - not on finder and not in disk utilities. I can't take the stupid thing back because it contains all my personal info which somebody with more computer expertise than I have could access. This means I am out my purchase price of $17. Ansh I hope you find a solution and share it with us.

If you have access to a PC, hook the 8 GB HP flash drive to it and it will probably work. If it does work, format the flash drive and return it. It appears HP flash drives are problematic.

Thanks for your reply, but I wouldn't dare return it unless I personally have deleted all the files.

Plug the drive into your Mac. Open Disk Utility from Applications/Utilities. Does the HP show up there? If so, Erase it FAT32 and then return it.

Let us know if it shows up in Disk Utility.

My friends showed up in Disk Utility but would not mount.

Hi Dennis, I just plugged the USB drive in and it showed up under Devices. I deleted my files from the drive and went into Applications/Disk Utilities and saw the drive there and am in the process of doing a 35-pass secure erase which my computer says will take 5 hours (maybe it means pass 1 will take 5 hours). Yikes! Is there anything else I need to do?

Thanks for your reply! Now I can take the stupid thing back and get my money back!

Hi again, I was in the middle of doing a 35-pass secure erase when the drive disappeared from Devices again. This time I selected zeroing out data which is in the middle of doing. Should I also do a 7-pass (or more) secure erase?

Thanks.

Hi, I'm in the middle of doing a 7-pass secure erase. Can you tell me how to erase the FAT32 formatting file? Thanks.

The 7 pass secure erase writes binary ones and zeros throughout the entire drive 7 times. Nothing will be left on that drive. Nada, zip, zero.

Do let us know what you end up with and if that solves your issues. I have NEVER once had issues with San Disk drives. I own maybe 6 and every one works with every computer I have ever tried them on, Windows, OSX, Linux, Haiku and even the funky version of Linux that came with my Acer Aspire Netbook!
