I did clean install and deleted all partition during setup as I have all data backed up in external HD ; the installation ends up with system reserved partition and primary partition C.
Grievously, i could not open the external HD as there is error massage "you need to format disk E (external HD) before you use it" i couldn't , since all data is in there. The external HD perfectly works recently (within 24 hours) tried checking with other machine also shown the same error massage.
I have not installed any program yet as concerning about over written. The previous 500 GB HD before clean install contained C , D , E , F , G , H , I , J partition . I need to recover the data from F , G , H , I , J partition.
What should I do to safely recover the whole HD data from previous partition mentioned above to the same HD (as I have no more external drive supported) and how could I safely access to external HD without formatting , please?
Additionally, I have full version of recovery my files . It helps a lot on recover the formatted partition yet current situation is different , i have never tried recovery the whole formatted HD and have no idea how to use it securely ; therefore, anyone who familiar with this software , please kindly help.
I desperately need assistance and would appreciate all recommendation,
