My Passport Wireless Pro - System Recovery or Hard Drive replacement

@Newzj82 the wifi password is stored in the following files:

/etc/nas/config/wifinetwork-param.conf:AP_ENCRYPTION_KEY="AAAAAAAA"
/etc/nas/config/wifinetwork-param.conf:AP5G_ENCRYPTION_KEY="AAAAAAAA"
/etc/hostapd/hostapd.conf.2G:serial_number=WX71AAAAAAAA
/etc/hostapd/hostapd.conf.2G:wpa_passphrase=AAAAAAAA
/etc/hostapd/hostapd.conf.5G:serial_number=WX71AAAAAAAA
/etc/hostapd/hostapd.conf.5G:wpa_passphrase=AAAAAAAA
/etc/wpa2G4_supplicant.conf:serial_number=WX71AAAAAAAA
/etc/HDSerial:WX71AAAAAAAA
/etc/wpa_supplicant.conf:serial_number=WX71AAAAAAAA

You should be able to DD the last 4gB of the disk to a file, open it in a hex editor, and search for wpa_passphrase= On Windows you can use DiskInternals Linux Reader, right click the unallocated space, click hex preview, and search for wpa_passphrase=

In order to get @jayband 's process to work I needed to create a partition in the remaining 4130mB and format it to fat32 using a slow format, and then delete the 4130mB partition. The OS is stored in that unallocated slack space and if you don’t properly delete it you may have some issues.
