hi ,, i have 8 gb adata pen drive , when i tried to format it then it said it is write protected and a searchea software callded hdd low level format and formatted it and it was being shown in explorer . but when i tried to format it default way it was again saying write protected . then i got a suggestion in the net
''1.Go to Run->regedit
2.MyComputer->HKEY_LOCAL_MACHINE->SYSTEM->CurrentControlSet->Control -> StorageDevicePolicies
3.Delete the StorageDevicePolicies in Your Registry.''
and formatted it in the default way but when i ejected it and re connected then it was not being shown in the explorer...



but when i connected it in the pc then disk security as well as antivirus detected it and when i went to disk management , every thing was healthy and ok . but the problem is it is not shown when i click my computer,,,,i took it to the another pc where it was detected and i formatted it but when conected to my pc then every where it detected except my computer.

Do you have another pendrive? Plug it in and see whether it has the same problem.

Is it your own PC or company-owned?

In the problem computer, does the drive have a drive letter? ( It is not clear whether the screenshot of Disk Management pertains to the problem computer or the other computer.)
