USB flash drive with corrupted directory

[ramblingron]

I bought a Transcend USB flash drive in India - 32 GB - unopened packaging - which Transcend later claimed is counterfeit. Using several computers, I cannot access the drive.
I cannot format the drive using both W7 and DOS formats on different computers. The format always runs almost to the end and then fails, reporting corrupted directory.
I am not trying to recover any data - I only wish to repair (uncorrupt) the directory
Is this possible?

OK, try Hiren's BootCD 15.0 and go to Hard Disk Tools. It is a liveCD, u boot in to the RAM and do it off line from W7.

Hi ramblingron


If counterfeit it could also have hardware faults as counterfeit flash drives often use reject components

In the worst cases they modify the controller chip to lie about capacity eg 16MB flash chip controller modified to pretend to be 32MB or 64MB.

Once 16MB capacity reached data loss occurs

throw it away or ask for your money back if possible

Thanks Mike for your help - I am beginning to think it is a hopeless case

Sorry to hear that. There is lots of counterfeit USB flash drive in India, u could have one. They are the cheapest versions and without quality parts.
