I have a Memorex Ultra TD v1.0 USB Device 160 Gb and has 120Gb free. The problem is that I can't copy a file that is 8 GB.

if you are referring to a usb drive

click start control panel administrative tools computer management device manager scroll down universal serial bus controllers you could see a yellow question / exclamation mark? ! or a red X

you will need to update/reinstall drivers

right click to reinstall drivers

if you can see your usb drive but its not working

ports (com&lpt) right click update driver if this fails to fix the problem

check the USB leads that attach to the motherboard usually red white green black make sure they are securely seated and have no dust build up on them dust will cause static and a lot of unforeseen problems to a computer and its parts

if you need more help with post a reply

hope it helps

My new Hp v165w 2GB pen drive can not copy file from my PC

try selct file right click send to

1. Try creating another folder and coping the content from the original to the new folder on the USB drive.
You may have stopped the coping process inadvertently during the copy process.

in fact your hdd is formatted in FAT32 filesystem for compatibility reasons but this file systems only can read files below 3 gigabytes or so, if you want to copybigger files you should backup all your hdd info and reformat it to NTFS filesystem that can handle these files

You can format it for solve this problem.

ITS virus problem which is playing with the inf file of the usb drive.
also another possibility is 1) the usb port ihas loose connections and disconnects i between drive sensing
2) certain 8 gb drives go back to a capacity of 2 gb drive if one formats it accidentally .

If your drive is partitioned with FAT32 then it cannot copy larger files. You have to format it using NTFS.
