Can't formated 4 gb sandisk usb drives

You don't need an image. Just format it. Put your drive into a USB port; right click on that drive after it appears in My Computer and select Format; set the File System drop-down to NTFS (better file storage space) or FAT32 (more compatibility in older operating systems) and click Start.

Usually, it comes formatted. However, you can re-format it (e.g. on a PC or Mac) using the usual disk format utilities, if you don't need any special/specific (SDHC) format features.
For instance, on a PC ... insert the USB SanDisk into a USB port. It will show up as a (storage) device on your "My Computer" window. Highlight that icon ... (put the cursor over it) ... and put your cursor on the FILE (menu) tab and click on it. It will display a drop-down menu with "Format" on it.
Click on the "Format" and it will guide you through the formatting process.
On a Mac, when you insert the USB SanDisk into a USB port, it will show up as a device on your desktop. You can use the "Disk Utilities" software (usually in the Applications - Utilities folder), to format it.

Your flashdrive usually shows 2 drives when inserted to your computer, one is the U3 drive and the other one is the removable disk drives. U3 drive is your separate partition for the U3 system and in order for you to store, copy, format your flashdrive, you should be selecting the removable disk drive, not the U3 drive. U3 is a read only memory drive that is responsible for your U3 to work (just like portable applications). Hope this helps.

hi, if you do not need data,go to cmd prompt format your pendrive using this cmd "format Z:"
then see your size

The pc you are using may be reserving that drive letter for some other device, unplug all other usb devices and try it again.

Hi,

You can download the driver for Cruzer micro from below website

Thanx

1. continue without solving
2. If you didn't remove the drive with the safe removal tool in the task bar ( lower right hand corner) the drive will lose it's ability to be mounted or seen by Windows and will not format. You will lose data.

you plug the SanDisk Cruzer Micro 4GB USB 2.0 Flash Drive into your computer open the file that says SadDisk and drag the files you want to download into the SanDisk file good luck!! :)

try formating in the following steps
1. right click on my computer then manage
2. click on disk management
3. right click on the flash drive then format
if the problem still occurs then there is some problem in the memory ic.
