    When you last deleted the contents of the flash drive, did you empty the trash? Deleted files will still take up space if the trash is not emptied. Try mounting the drive and checking to see if the files that used to be on the drive show up in the trash, If they do, empty the trash before ejecting the drive. If they do not show up in the trash, another option would be to try erasing the drive using Disk Utility.

    Just reformat it FAT32 with Disk Utility. If formatting fails, then you should probably dump that flash drive and buy another. They're very cheap.

    Recommended USB stick?
    I need to buy a USB memory stick that I can use between a Mac and a PC. I have had some in the past but they corrupted quite quickly, presumably because they were switching between the two. Does anyone have any recommendations?

    Thanks

    Any USB flash drive will work. Since most, if not all flash drives are pre-formatted at the factory as FAT-32, you should not attempt to reformat them. And if you do, don't do it with your Mac. Use a PC.

    Regards.

    May I ask chscag ... why use a WinPC to format a flash drive FAT32? I've always used Mac Disk Utility to reformat a flash drive with satisfactory results, cross-platform.

    Because most folks do not know that when reformatting a flash drive as FAT-32 using Disk Utility, that they must format as MBR and not GUID. Unfortunately GUID is the default. And what that does is create a small EFI 200 MB partition on the flash drive. That means the drive now has two partitions. That's not a problem when using the drive on your Mac, but Windows will only "see" the first partition. (200 MB)

    Try it with an old flash drive that you have laying around to see what happens.

    Regards.

    Eh, almost all flash memory is made by 2 companies regardless of what "brand name" is slapped on it.

    IMHO, just buy the cheapest flash drive you can find for the money.

    When people say they've had flash drives get corrupted, I usually ask them to show me how they eject the drive from the computer (either Mac or PC). That usually explains what's really happening fairly quickly (ie, they do not properly dismount the drive before removing it).

    Almost every friend I have does that and says to me, well it did not corrupt! I ask them, then why does both Windows and OSX yell and warn you to unmount first? Just to be yelling?

    I tell them you might get lucky and have no issues but someday you will yank that flash drive and loose everything. I have seen it happen all to many times.

    You sir are very correct.

    Agreed. I've always had good luck with SanDisk drives (I actually bent one, bent it back to its original shape and it still works like a charm). Just as I only buy WD HDs, if a brand works for me, I'll use it until it doesn't.

    Absolutely. OS X and Windows have anger issues .

    There's a reason OS X, Windows and Linux require you to unmount drives. It's not there for no reason.

    Two things I like about SanDisk - other than its quality/reliability - are:
    1. the silicon exterior - good for finger grip, and
    2. its compactness, good for when the drives are fitted side-by-side in a USB hub.

    Beside me as I type are five flash drives, including Anonymous, Legend, MyFlash, Rundisk, and SanDisk. The best is left 'til last.

    I have never yanked a Flash Drive from a Linux system, so thanks for confirming it warns you also!

    Hughvane, I love Sandisk Flash drives also. My ONLY complaint is that when plugging one into one of the front mounted Slanted USB ports on a Dell Optiplex, sometimes the white lock button comes loose and the USB plug retracts! Otherwise I have never had one issue with a Sanndisk drive. I have had some Kingston's that would not work on some PC's but worked fine on others no matter how you formatted them. Never one issue with Sandisk.

    Chscag, thanks for that about making sure Disk Utility is set at MBR and not GUID. That makes total sense and probably why some are complaining about drives formatted on OSX.
