It seems your recovery program is at fault
I googled this answer from this page

http://www.howtogeek.com/forum/topic/d2d32-type-mismatch-part-3-of-my-problems-

Hope it works

To enable disk-to-disk recovery (hard disk recovery), activate the BIOS utility,
then select Main from the categories listed at the top of the screen. Find D2D
Recovery at the bottom of the screen and use the <F5> and <F6> keys to set this
value to Enabled."

I need a acer aspire one happy recovery disk


The Acer Aspire One Netbook has a hidden partition on its hard disk drive which allows recovery of
1. operating system to original factory image (with no recovery disk required)
2. applications (selectable)
3. drivers (selectable)
If the netbook came with pre-installed Windows XP, use Acer eRecovery Management by
1. pressing start button at bottom left corner of Taskbar
2. hover cursor over All Programs then Acer Empowering Technology
3. then click on Acer eRecovery Management and follow subsequent recovery instructions
Alternatively, on powering up, press Alt and F10 together while Acer logo is showing.
If this doesn't work, there is the possibility that the D2D recovery is not enabled for startup.
To enable D2D recovery,
1. press F2 on powering up to get into the startup utility
2. cursor over to the Main tab
3. cursor down to D2D and enable it.
4. save changes when exiting - system will reboot
5. again, press Alt and F10 together while Acer logo is showing.

HOW CAN I RESTORE MY ACER TRAVELMATE 2200 without the original disk??????????????? NOW CAN U ANSWER THAT...ASAP


Hello !

Note: the recovery process helps you restore the C: drive with the original software content that is installed when you purchase your notebook.

You can try ALT+F10 or CTRL+F10 during the initial boot cycle. This should prompt the laptop to access the recovery partition on the hard drive.

If it doesn't work :

Activate BIOS Setup Utility, press <F2> during POST.

Check the BIOS settings.

a Check to see if "Acer disc-to-disc" function is enabled or not.
b Make sure the [Acer D2D Recovery] setting in [Main] is
[Enabled].
c Exit the BIOS Setup Utility and save changes. The system will
reboot.

Hope this helps.

My Acer Aspire one Netbook XP(SP3)'s system recovery doesn't work


Are you trying to access your original recovery software the one that is located on a separate partition? If you are and aren't able to, that particular partion might be currupted. your only option would be to try to install your software with a disc.

I hope this helps.

Acer Aspire 5920 alt f10 to use my recovery dsk mismatch d2d32


This a very common error. I too have suffered from this but after about 15 hours of fighting with it.. I fix it. I could not use the ALT + F10 keys as I would get the D2D32 Type Mismatch Error. So lucky me when I got my laptop from acer I made the recovery DVD's just in case. But to my suprise Booting from the DVD disk also would fail with the D2D32 Type Mismatch error. I even try maken new recovery disk with some luck. the new disk worked one time. But I started to run the recovery on disk one and when it asked for disk 2 I hit the power button thinking it would still boot, as I didnt want to wait for the recovery process to complete. So I ended up with a acer laptop with no o/s installed and was not able to use the Alt + F10 as explaned above or Boot using the recovery DVD's... so how did I fix this little set back... simple

I broke out the windows xp install Boot cd and Booted my system with that. let it run all the way to the partation/Format section on windows xp setup. I left the partation as it was and formatted it with the quick option. BE VERY CAREFUL AT THIS STEP... MAKE SURE YOU DONT FORMAT THE WRONG PARTATION THE 9 GIG OR 10 GIG IS WRONG. IT WAS DRIVE LETTER F: ON MY SYSTEM. JUST MAKE SURE IT IS DRIVE LETTER C: THAT YOU FORMAT...After it was done with the format I powerd down the system and tried to Boot from the Recovery DVD and it worked. No D2D32 Type Mismatch error. "{ But I let it finish this time around"} So to keep it simple. all you need to do is keep the partation the same, just format it and it your recovery will work. both ALT + F10 and /or the DVD"S Boot. it the ALT+F10 by chance dont work... theres a quick fix also. you need to files called MBRwrWin.exe and RTMBR2.bin and they have to be on the root of drive c:...{Root - just copy them to C: } and then from a command prompt with Adminastration {right click cmd } and type MBRwrWin install Rtmbr2.bin <Enter> ALT + F10 is now ready and fixed...


if you need help let me know or just to give some feed back
email me at cyberburn666@yahoo.com
Good luck it works. I just went from on os installed to vista... with factory recovery working like the day I got it....

D2d recovery


Is the d2d erecovery function enabled in the bios?

To check, activate the BIOS utility, press <F2> during the POST; while the notebook PC logo is being displayed.

To enable D2D recovery ard disk recovery), select Main from the categories listed at the top of the screen.

Find D2D Recovery at the bottom of the screen and use the <F5> and <F6> keys to set this value to Enabled.

That should allow you to use the F10 function key to activate D2D.
* Note: D2D e-recovery is not in Acer Empowering Management.
AEM is a power management utility that supports ACPI (advanced configuration and power interface) which allows for maximum power conservation and maximum performance. (Managed by the windows OS)
