LLFTOOL is a utility for low-level disk drive formatting, also supports formatting of FLASH cards using a card-reader.
1. Download this tool: http://dl.dropbox.com/u/4040651/LLFTOOL.EXE
2. Format thumbdrive
(WARNING: After running this low level format tool, the whole USB flash disk surface will be fully erased. Therefore, data restoration will be impossible after using this utility!)
Files on a flash drive can be corrupted if it is not removed from the USB port properly. Before removing the flash drive click on the Safely Remove Hardware icon and then click on the flash drive you want to remove and then remove the flash drive when the computer message says it is Safe to remove. To restore the flash drive you may need to format the flash drive, but you will lose the data stored on the flash drive. If you need the data on the flash drive this program may help: - Digital Photo Recovery www.artplus.hr/adapps/eng/dpr.htm
When the flash memory device appears to malfunction it maybe possible to restore it by reformatting it. Insert the flash drive into the USB port then Click on Control Panel - Administrative Tools - Computer Management - Disk Management. Then right click on Disk 1 removable drive and click Format. After the flash drive has been formatted it will indicate that it is Healthy. You need to format the external drive. Format the drive as primary drive and in FAT32. Insert the external hard drive into the USB port then Click on Control Panel - Administrative Tools - Computer Management - Disk Management. Then right click on Disk 1 removable drive and click Format. After the flash drive has been formatted it will indicate that it is Health
Flash drives by default use the FAT32 file system. FAT32 has a limit of 4gb per file. So you could have four 4gb files on your pen drive, but no files bigger than about 4gb. You could use the NTFS format, but it's not suggested for flash drives since it reads/writes much more often than FAT and will make the drive lifetime MUCH shorter.
Far too often these little things have an almost invisible read/write protect button on them. Look carefully, over the entire surface of the USB Flash Drive. You might have this switch turned to Write Protect, which means there is nothing you can do, until you turn it the other way, and allow the device to be written to.
