My new exFat 128GB flash drive will not allow it to copy to because it states "write protected". I have a Wndows XP system. It will allow me to copy some files but it stops and then indicates it's "write protected". I re-format the flash drive and copy MP3 files but will not allow me to copy more files. When I format drive it indicates 125GB capacity (thought it might be a forgery). I downloaded the latest drivers from MS. Is there a way to confirm that the drive is actually a 128GB drive ? Any suggestions ?

when you go to the computer menu there should be an overlay with that hard dricve and how much room it has left 125 gb is not a huge amount an it will come with a microscopic amount saved for other programs. how big are the files you are bringing over?

What brand of drive .?
Engineers , scientists and hard disk manufacturers
Use 10^6 for million
Computer programers & scientists use 1024 x 1024
So you get less in GB or TB shown in windows than stated by manufacturer
To check for USB or flash memory with fake firmware and wrong size
Use software such as
H2testW

Available From various sources
It fills dish with 1 GB files until full
Then reads them back and checks checksum for recovered files
This detects if disk is damaged or fraudulent

Was it originally formatted in exFat
Rather than fat 32 or NTFS ?
Wiki shows windows XP needs a specific Kb update to support exFat

Is exFAT journaled? Try running scandisk on it, fixing it, and trying it again.
