My passport is new (in fact I bought 2) The one I decided to format to be sure no executable sofware was remaining on the disk is not usable anymore. (the other one is working fine)
I followed the formating instruction using classical tool from Windows7. Deleting volume is working fine, but when I request to create new simple volume using NTFS, the only feedback I have, after quite a long time (more than 5’) is a message that process was not ending properly, and only RAW volume is available.
Comming back to desktop I have a message that I need to format disk before use. I agree to format in the dialog window, requesting NTFS default volume, and the result is same.
remark : my laptop has USB2 port.
Thanks in advance for any support Icould get
