HP pen drive 32gb
in the diskpart shows no media and size 0 bytes
unable to format = > error - insert a disk and try again
chkdsk doesn't work => Cannot open volume for direct access.
same for disk check using usb properties
Device Manager doesn't show option to format disk. shows only change drive letter and properties
already tried changing it for fast performance policy
other external tools non even showing this drive so unable to format or to generate MBR
with device manager after trying convert to MBR shows error to insert disk with proper type
tried updating drivers, changing registry value but no luck
other usb devices works fine
this device was working properly till the morning, then I tried to create two partitions but was able to create one partition and rest unallocated
then deleted volume and created single partition with all space
then tried make it bootable for win 7 but in between power gone and onwards started this problem
