I assume you should have said.....

How format my Sony 4GB flash drive

how can find the drivers to format my Sony flash disk
........

No drivers are required for a flash drive - generic drivers that are built into Windows are used.

If you can access the flash drive's drive letter fine in My Computer or Windows Explorer, RIGHT clck on the drive letter for the flash drive, choose Forrmat.
......

If you cannot see the drive letter for the flash drive in My Computer or Windows Explorer, you CANNOT format it.

Go to Start - Run - type: diskmgmt.msc , press Enter

Scroll down the resulting screen and look for a Removable drive with a ~ 4gb total size (it will be a bit smaller than that) stated at the left side of a rectangular box that shows the space on the drive.

If you DO NOT see that, the computer is NOT detecting the drive at all.

Try pluggeing it into a DIFFERENT USB port, then go to Start - Run - type: diskmgmt.msc , press Enter again to see if it shows up there.

If the rectangular box for the Removable ~ 4 gb drive shows RAW or unallocated, data on the drive has been DAMAGED.

You CANNOT fomat the drive if you see that.

If you are NOT concerned about whatever data was on the drive previously, if you delete the partition on the drive and make a new one, the flash drive will be usable again andwill; show up in My Computer or Windows Explorer.
However, you CANNOT delete the partition on the drive in Windows due to Microsoft's defaults. There may be programs on the web you can use to do that, however most programs on the web can only format the drive - they can't format the drive if it doesn't show up in MyComputer or Windows Explorer, or delete the existing partition and then format it.

You can use certain programs to repair that data damage, then whatever data it had on it previously will probably be visible again, and the flash drive will then show up in My Computer or Windows Explorer.

The correct cluster size for 4GB formatted using FAT32 is 4K. Did you try going to My Computer, right clicking on the flash drive & selecting Format?

"Invalid media or Track 0 bad - disk unusable."

"the format can not complete successfully"

The FAT32 software partitoning on the flash DRIVE has probably been DAMAGED by you unplugging the flash DRIVE while Windows was running without clicking on the Safely Remove Hardware icon in your taskbar at the bottom right right of the desktop screen and choosing to STOP accessing the drive.
(You may need to click < at the left end of the icons there to reveal the Safely Remove Hardware icon.)

Windows cannot format the flash DRIVE successfully when that software partitioning is damaged.

You can eliminate the problem by deleting the drive partition and making a new one.
Disk Management in Windows software partitions and formats a drive partition at the same time when you make a new partition, but you cannot delete the partition and make a new one by default on a flash drive in Disk Management in Windows.

You have to use something such as the Testdisk program to repair the FAT32 software partitioning, or you have to use something other than Windows itself to delete the partition and make a new one.
....

You don't need to use cmd mode to format a drive. You just RIGHT click on it's drive letter in My Computer or Windows Explorer and choose Format. That doesn't delete the software partition and make a new one - it just formats the existing software partition. The same goes for format in cmd mode.

Similar applies to your flash drive except that you should see a Removable drive in Disk Management that has a total capacity of a bit less than 2 gb.
