"A disk read error occurred" appears on screen after choosing to boot into Windows XP from GRUB.

Here, sda is a 160GB hard disk with quite a few partitions and 3 OSes installed. I am able to boot into Linux and Mac OS fine, but not into Windows anymore. The Windows system is located on /dev/sda1.
I cannot recall how exactly have I used testdisk but it once said:
Disk /dev/sda - 160 GB / 149 GiB - CHS 19458 255 63
The harddisk (160 GB / 149 GiB) seems too small! (< 169 GB / 157 GiB)
Check the harddisk size: HD jumper settings, BIOS detection...
So far I have tried to "fixboot" and "chkdsk" from a recovery console on the affected windows partition (/dev/sda1), the plug off power cord for 15 seconds trick, reinstalling GRUB, repairing the MFT and boot sector of the affected partition via testdisk, what next please?
Thank you!
