How To Format A Write Protected Flash Memory ?

¿You already tried this one?...

Run CMD


1. diskpart
2. list disk

Then in the 3º step, put the correct number of disk in the list for the usb flash (if it's listed in disk 3, then you'll have to write select disk 3).

2. select disk #
3. clean
4. create partition primary
5. select partition 1
6. active
7. format fs=fat32
8. assign
9. exit

with that commands you will format the flash drive in fat32, if you have a large drive you can select also "format fs=ntfs" in step 7.

good luck!

 

Format SSD drive or any drive

Hi Thomas

Think of a hard drive or SSD as a book . . .

A Quick Format basically deletes the contents page (File Allocation Table), whereas a Long Format will also delete all the pages (Files)

If a quick format is taking 2 hours on your SSD and you are experiencing problems with Windows, when only performing a Quick Format, then I would suggest the formatting operation is not the problem, most likely that SSD has a problem. A Quick format on that
drive, should take approx. 10 minutes . . .

 

Formatting an SSD without using Quick Format Option


This process will degrade the performance of your SSD. Unlike hard drives where new information is written directly over old information with no decline in speed. SSD's are blazingly fast when writing to empty NAND. However if there is no empty NAND available the SSD process changes to a two-step approach where the NAND has to be "cleaned" and then written to. This slows down the SSD considerably. (The trim command under the windows optimize function essentially identifies the old, not needed, information and assists the SSD in pre-cleaning the NAND's so that the SSD can operate at full speed).
The only way to completely clean SSD is through a process known as secure erase. It essentially provides a blank SSD to write on. Formatting is nothing like that and a quick format essentially clears the record of the information that is written on an SSD so that Windows can treat it like a blank SSD, but the SSD still has to go through the two-step process. The NAND's are still full of old information and are effectively cleaned during periods of non-activity. A full format on the other hand will effectively write on every single NAND completely filling the SSD. If you want to start off with a clean fast SSD, use the manufacturers software and/or other generic software designed to secure erase the SSD.
