My 1GB flash drive mysteriously dropped to a useless 267KB device. No online advice made sense to this non-Geek Mac user until I came across your Web page. I tried your first suggestion to empty the trash while the flash drive is connected to the computer. It was the simplest of all the troubleshooting schemes–but it worked instantly, restoring my device to its full capacity.
Thanks a whole lot, Ant.

When I erase the flash drive, it still says there are 9 folders, 38 files and 6 MB used.
It says there is a Partition map but when I look at it, there is only 1 partition of the same capacity as the flash drive.
What’s going on, do you know?
I emptied the trash, again, and the file count went up to 40. I repaired the disk and the file count went up to 43. It must be keeping a log. I erased, again, and am back down to 38 files.
I can’t see any folders or files on the disk.

Thanks for any help you can give me.

hiya, and thanks for this – very easy to follow.

i have a new 16GB flash drive, unused, but my Mac reckons there is only 14.3GB free space on it. Does that means the files that arrived on the drive from the manufacturer are taking up over 1GB of space?!
This seems crazy. How can I tell which of the files I really need to keep on there so the drive will work, and hat I can scrap straight away?

Thanks!

I use my flash drive between my macbook and my PC from work, but after a while i notice that my flash drive saids that no space was available still been empty, i used the disk utility option and worked perfect… but after usuing it i notice that i had less space in my flash drive… went from 16GB to 15.57GB, any idea why this happens?

Thank you so much! I was on the verge of crushing and throwing away my USB as it has been acting up and allowing me to save less and less every time I tried to use it .. after following this, it works like new and I finally have full availability again!
GREAT walk through!

I’ve just erased a 2 Gb Kingston Data Traveller Flash Drive. Message came up:

“Disk Erase failed

POSIX reports: The operation couldn’t be completed.
Cannot allocate memory”

Removed Flash drive. No disk image.

Shows up on Disk Utility but cannot reformat.

Should I buy a new Flash drive?
