Acer eRecovery management Restore system to factor default but I don't know the password


Locate and Unhide Hidden Rescue Partition
  • 1 Access the Diskpart command prompt. Acer stores custom eRecovery passwords on your computer in PQService, a hidden rescue partition. Locating this partition requires accessing the Diskpart utility from the command prompt. Diskpart allows you to run a scan on your hard drive and bring up hidden partitions. To access Diskpart, go to Start and type "cmd" in the search bar to bring up the black command prompt box, and then type "diskpart" at the prompt to switch to a Diskpart prompt. Depending on your computer, a new command prompt may open with the Diskpart prompt.
  • 2 Scan your computer configuration. At the Diskpart prompt, type "rescan" to run a system configuration check. When the scan finishes, you will receive a message informing you the scan is complete. At the command prompt, type "list disks" to bring up available disks and then type "select disk 0."
  • 3 Locate the hidden partition. At the command prompt, type "list partition" to view a list of partitions on your disk. Locate the partition with no name and a size of approximately 10GB. At the command prompt, type "select partition (number)."
  • 4 Determine the partition type and unhide the partition. The hidden PQService partition will be either a type 27 or a type 12 partition. If the partition is type 27, unhide it by typing "set id=07 override," and if a type 12, then unhide it by typing "set id=0B" at the command prompt.
  • 5 View the PQService partition. Return to the disk containing PQService by typing "select disk 0" at the command prompt, and then type "list volume" to view the contents of the disk. PQService will be visible in the list, preceded by a number. Type "select volume (number)" and then assign PQService a new drive letter so you will be able to open and view it from your computer interface window. At the command prompt, type "assign letter=f."
Reset eRecovery Password
  • 1 Open PQService. Navigate to the drive containing PQService. Find the file "aimdrs.dat." Right-click on the file and select "Open with" and then "Textpad," "Notepad" or another text editor you prefer.
  • 2 Open the file and find the password. Open the file with your text editor and locate the eRecovery password. Look for a line that reads, "Password=password name," "Hint=the password hint." Write down the password and close the file.
  • 3 Open eRecovery using the recovered password and follow the instructions to create a new password.

How to Reset an Password for Acer eRecovery


Acer eRecovery is a vendor-specific method you can use to restore your computer to its original factory settings, or to custom settings you create and store on your hard drive or other removable media. eRecovery also contains a back-up utility you can use to back up data to your hard drive or other removable media. Access to eRecovery requires you to use the default "000000"password or one you select. While it is important to store a custom password in a safe location, if you lose or forget it, there are steps you can take to reset your Acer eRecovery password.
Access the Diskpart command prompt. Acer stores custom eRecovery passwords on your computer in PQService, a hidden rescue partition. Locating this partition requires accessing the Diskpart utility from the command prompt. Diskpart allows you to run a scan on your hard drive and bring up hidden partitions.

Step 2. Scan your computer configuration. At the Diskpart prompt, type "rescan" to run a system configuration check. When the scan finishes, you will receive a message informing you the scan is complete. At the command prompt, type "list disks" to bring up available disks and then type "select disk 0."
Step 3. Locate the hidden partition. At the command prompt, type "list partition" to view a list of partitions on your disk. Locate the partition with no name and a size of approximately 10 GB. At the command prompt, type "select partition (number)."
Step 4. Determine the partition type and unhide the partition. The hidden PQService partition will be either a type 27 or a type 12 partition. If the partition is type 27, unhide it by typing "set id=07 override," and if a type 12, then unhide it by typing "set id=0B" at the command prompt.
Step 5. View PQService partition. Return to the disk containing PQService by typing "select disk 0" at the command prompt, and then type "list volume" to view the contents of the disk. PQService will be visible in the list, preceded by a number. Type "select volume (number)" and then assign PQService a new drive letter so you will be able to open and view it from your computer interface window. At the command prompt, type "assign letter=f."
Reset eRecovery Password
Step 1. Open PQService. Navigate to the drive containing PQService. If you are using Windows XP, use My Computer; if you are using windows Vista, use Computer. Find the file "aimdrs.dat." Right click on the file and select "Open with" and then "Textpad," "Notepad," or whatever text editor you prefer.
Step 2. Open file and find password. Open the file with your text editor and locate the eRecovery password. Look for a line that reads, "Password=password name," "Hint=the password hint." Write down the password and close the file.
Step 3. Open eRecovery using the recovered password and follow instructions to create a new password.

PQ Service, what is it?


This is not added by Windows, it's part of the Acer eRecovery program.
Here is the information.
From the Acer website - "There is also a third, hidden partition called PQSERVICE. The PQSERVICE partition contains the files necessary for the Acer eRecovery to reinstall the operating system, setting the system back to the way it was the day you purchased it, create recovery media, or reinstall drivers and applications"

How to acer restore 5742z with PQService with reformatted drive


The eRecovery restore partitions only work in Windows if both are intact. Otherwise you need a disc. I would say you have 2 options, working with ACER or doing a non OEM setup with a Windows installation disc.

Acer
http://acer.custhelp.com/app/answers/detail/a_id/2631



A free legal Windows image can be downloaded. Check the MS Product Key sticker for what version your system came with. You will have to use your key. IT MUST BE THE SAME VERSION.



Windows
http://www.mydigitallife.info/official-windows-7-sp1-iso-from-digital-river/ This is SP1, but look for the links if you need an image without it. Again this is Product Key specific.



I don't work with any laptops, but I am a bit of a generalist when it comes to IT.

PQSERVICE


I'm trying a backup of my Aspire One PQSERVICE to DVD after a near catastrophic partitioning experiment.

So far, I've booted from a Knoppix live CD and I'm trying partimage to copy the contents of the PQSERVICE to an image file on an external usb hard drive. Hopefully I can burn the image to DVD-R. So far, it looks promising.... even if I can't make a DVD-R from the image, I can use partimage to restore the PQSERVICE from the image file if I have to.

Another option would be to boot a knoppix live CD and just copy the contents of PQSERVICE to another disk or partition (not NTFS though). Linux doesn't care about the hidden drive partition settings that Windows uses.

D2d recovery


Hello Sir / Madam,

Many Acer systems come with the ability to press ALT+F10 to kick off the Acer Recovery applications from a special hidden recovery partition. Sometimes this won’t work and there can be a number of reasons.
1. D2D Recovery is “Disabled” in the BIOS (Main menu).
FIX: Enabled it and try pressing ALT+F10 again as the computer boots.
2. The Acer hidden recovery partition (PQSERVICE) has been removed or damaged. If the disk drive is a replacement drive then you won’t have this partition.
FIX: Unless you have previously imaged the PQSERVICE partition it will not be possible to use D2D recovery. You will need to restore from the Acer Recovery CD/DVD.
3. You have converted the FAT32 partition on the hard drives into NTFS. Acer D2D recovery won’t be available if you perform this conversion. Ironic that NTFS is a more desirable disk format to use but Acer won’t support this in their systems!
FIX: Restore your system from the recovery CD/DVD media.
4. The special Acer Master Boot Record (MBR) has become corrupt or has been overwritten with an non Acer MBR. As long as the PQSERVICE partition is there or you can get your hands on a couple of Acer service files for your model, then you can remake the special Acer MBR. Let’s cover how this is done.
  1. Disable D2D recovery in the BIOS. Can be found in the “Main” menu section. Save the BIOS settings and exit.
  2. Log into Windows with an “administrator” level account.
  3. Download ParTEDIT32.ZIP (registration required for download).
  4. Extract PTEDIT32.EXE from the zip archive and run it.
  5. Identify the PQSERVICE partition by its type or size. It is likely to be 12 or another custom value and is likely to be reasonably small in comparison to the other normal partitions - see the example below from a working factory default Acer. Click the Link below see the image full size. http://www.roundtripsolutions.com/blog/wp-content/uploads/
  6. 2007/10/AcerDiskRecoveryBroken_F031/hidden.jpg
    Change the type to “07′ (Installable File System NTFS, HPFS) and “Save Changes”.
  7. Reboot the computer and login with an “administrator” level account.
  8. You should then be able to open up a command prompt and navigate to the PQSERVICE drive.
  9. Enter the following command at the command prompt:
    mbrwrdos.exe install rtmbr.bin
    - You may have to search for these files and change into the relevant directory.
    Note: This step writes the Acer MBR, with mbrwrdos.exe and rtmbr.bin being the special service files.
  10. Close the command prompt window and reboot.
  11. Go into the BIOS again and enable D2D Recovery. Save the BIOS settings and exit.
  12. ALT+F10 should now start Acer Recovery as the computer starts.
  13. The Acer MBR ensures the PQSERVICE partition is hidden therefore there is no need to reset the partition type back to 07 - well there shouldn’t be if all has gone well. If you need to manually reset it then run PTEDIT32.EXE again, set the partition to 12, or whatever the original value was, and save the changes to complete the process. Reboot and it should now be hidden.
If Windows is unbootable, due to whatever issue, you can always use the Ultimate Boot CD for Windows (UBCD4Win) along with a copy of PTEDIT32.EXE to achieve the same results. Likewise, use UBCD4Win along with PTEDIT32.EXE if the PQSERVICE partition is being changed back to a hidden one by the existing MBR. We’ll leave that as an exercise for those who need to do it! It has been pointed out in the comments that UBCD4Win already has an application that will do partition maintenance, so checkout TestDisc if you go down that road.
If this is a new drive or someone has completely wiped the drive, including the hidden partitions, it may be necessary to use partitioning software to recreate the partitions that the Acer Recovery system is expecting! You’ll also need to restore an image of the recovery partition from a previously made backup, so it is worth making that backup image straight away while the laptop is still new and shiny, and certainly well in advance of any problem.
A final word or two of caution: take great caution when playing around with partitions on an Acer system… you have been warned… and remember to make the backup media disks as soon as you fire the computer up for the first time!


Thanks
Good Luck

D2d recovery


Send me an e-mail and I will send you the fix! If you can't downloadload it from the below link. I had the same problem. The mbr was replaced, you have to add RTMBR.BIN to the MBR and it will work again. As long as you can get on your desktop and run this bat file you will repair the D2D again. Took me an hour to learn what was wrong, It works 100% though.

 

I have the Aspire 5610Z with the 2GB 533 mhz memory Stock.
