Acer Laptop Recovery32 Type Mismatch

I am working on my son's Acer Aspire 5520-5912. I purchased and installed a new hard drive, a "Western Digital Scorpio Blue WD1600BEVT 160GB 5400 RPM 8MB Cache 2.5" SATA 3.0Gb/s Internal Notebook Hard Drive - OEM" which replaced the Toshiba MK1637GSX factory installed (same size). I have the recovery disks from Acer for this system. However I get an error message "Recovery32 Type Mismatch" when trying to install them. I have checked the system information via F2 and confirmed that the system "sees" the new hdd. I researched a lot of posts that indicate ths error is related to the HDD not being formatted and partitioned and that the Acer Recovery disks do not perform this function for you. I could not find the 'Post Acer Disk Formatter CD ISo Image' as mentioned in other posts on the Acer Website. However I do find on their Download/Support pages under my specific product and the "BIOS" page a file called "Acer Bios V1.33" with a size of 2.2 MB. Acer also has the following warning posted on this page "Flashing the wrong BIOS can cause harm to the system. Acer recommends that you should only upgrade your firmware/drivers if you have been instructed to do so by an Acer Customer Care representative. By using these firmware/drivers you agree to accept the possibility of product failure." So I figured I better do some additional checking. The previos system BIOS version is V1.08 (per F2), so it appears that this file is newer.

Is this the file I need?
I welcome any advice or help in getting this laptop back up and running.

Thanks

"I have the same problem. I try to erecovery Disc and I am getting a "Recovery32 type mismatch error". Try formating it with windows 2000, it is hanging....When i tried it with 98 it is not showing C: drive because it is NTFS formated.

Still trying something.....
