I have flash drive 1 GB MyFlash / A-Data / Prolific chipset .The problem is that on Windows and Linux systems is read only or write protected.
I try a lots of software to fix and unlock but its imposible.There is no hardware switch on it to lock/unlock.Somehow I found that file system on flash is Raw and there is MBR on it.I want to delete these MBR or delete all partitions.I don't care about data on flash.How can I do that?

And you are positive that there is not lock switch? Can you read anything on the disk?

Are there any NTFS permissions on the disk. Can you take ownership of the files?

Not such switch I'm sure.There is no NTFS partition.Filesystem is RAW. Partition style - MBR.I'm able to see files only in Linux.

I was trying everything that I found on internet for this problem.I don't need links and forum discussions.I spend a lot of time there and NOTHING. Like I said none of the mentioned software doesn't work.Once again:
1.No switch for lock/unlock
2.Partition type is RAW
3.There is MBR records on it.
4.No standard windows/Linux solutions are working/chskdsk; format; fdisk and so on/
5.Most of third party software for partitioning or recovery are tested.

ok - here my guess  then : it is bad; dump it. It happens a lot, and they're cheap nowadays

not sure if you have tried some partition manager or not.

Paragon Partition manager is a very good one for managing partition in cross platform environment as it is  not dependent on your OS file system.

Just that its not a freeware/shareware.

I try with Paragon Partition manager and again no results.I realize that this flash drive was make bootable via HP drive key boot utility.So if there is some utility to do reverse process will be great.
