Hi There


I have had nothing but trouble with my Extensa 5620 ever since upgrading from XP to 8.1 and then to 10. I decided to facory restore it (using discs) and then all was progressing well with the eRecovery process until I inserted the Backup Disc 1. I then got the following error message 


Err: callZ:\Patch\Patch.bat,dwErr=3 (thankfully I took a photo!).


After clicking ok, the eRecovery screen is now stuck on 'Please wait a moment while copying files'.


Can someone please tell me what the error message means and how I can continue with the factory restore and overcome this problem?

    so you are factory restoring to windows XP?


    try this if you have a keyboard language selection:

    press Shift+F10 at language/keyboard screen options, to enter Command prompt.
    once in command prompt type
    then on diskpart type
    list disk
    take note of the correct disk ID to erase
    select disk x
    (x is the ID of your HDD to erase)
    clean all
    type exit


    be very patient, it will take hours to end

    then proceed to windows installation

    G'day Ironfly

    Thanks so much for getting back to me!

    According to Computer Management console I have 1 disk (disk 0) with 3 partitions (PQSERVICE, ACER C: and E: which I created)

    When following your instructions I got to DISKPART>clean all and it said-

    'The selected disk is necessary for the operation of your computer, and may not be able to be cleaned.'


    Should'nt I be erasing or deleting the disk instead?

    if you did the diskpart command from the recovery CD, normally diskpart will let you erase completly your HDD.


    or you can use a third party tool like gparted:
