"Error reading sector 17309187" means your Hard Disk as either bad sectors or as errors on it.
If it is errors then doing an Error Check on your Hard Drive should fix the errors.
How to do an error checking on Vista
1- Open Computer by clicking the Start button Picture of the Start button, and then clicking Computer.
2- Right-click the hard disk drive that you want to check, and then click Properties.
3- Click the Tools tab, and then, under Error-checking, click Check Now. Administrator permission required If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
To automatically repair problems with files and folders that the scan detects, select Automatically fix file system errors. Otherwise, the disk check will simply report problems but not fix them.
To perform a thorough disk check, select Scan for and attempt recovery of bad sectors. This scan attempts to find and repair physical errors on the hard disk itself, and it can take much longer to complete.
To check for both file errors and physical errors, select both Automatically fix file system errors and Scan for and attempt recovery of bad sectors.
4- Click Start.
Depending upon the size of your hard disk, this may take several minutes. For best results, don't use your computer for any other tasks while it's checking for errors.
If you select Automatically fix file system errors for a disk that is in use (for example, the partition that contains Windows C:\), you'll be prompted to reschedule the disk check for the next time you restart your computer.
If you have bad sectors then I would use the manufacturer of your HD tools to diagnose your drive and see if it is failing or if the bad sectors can be fix.
Hope that helps
