Cannot copy files from hard drive

I had got problem on my desktop since it was old hard drive too but still not yet figured why it was gone for errors.Their are some reasons which i believe for that my hard drive gone errors.I searched on internet but no avail good answer for this except data recovery.
For recovering data i had tried to scan the drive and then tried to copy important files but though my hard drive was like going to dead.It showed as my pc was stucked even i cannot close folders or open etc.
My system was on windows xp Pro and i cannot run scandisk in this windows xp.however from microsoft website i get some information in order to run and recover.Their are two options one is command prompt another is just mouse clicking so i used this method.

First we need to open my computer folder and right click on the drive which we need to perform chkdisk so when you cliked choose properties.From the dialog box click tools menu and then click check box Automatically fix file system errors.Also if you ned to check errors and fixing etc check the second box too since this can help the hard drive to recover data.
I had slolwly copied some important data files from hard drive and i moved all the files which i needed and it this stage my hard drive was unable to respond and even my C drive gone dead as it says format the drive when i tried to open that drive.
I was running XP on my D drive since their was problem few months back so at that time i installed it on D drive Also i may think this would be another reason for errors but still i didnot figured yet.Atlast i formatted the hard drive and installed xp again.
From my side if you got such errors then immediately remove important files.
Never store the programs and large downloaded files since i did and got errors during that time.

Install xp from usb on preloaded vista

I have been searched all over the internet from the past 20 days and founded many solutions for installing xp from usb but I had choosed only multiboot cmd and this did worked for my lenovo laptop since the dvd was dead and it was already repaired several times so i dont have any hopes on it if repaired also.I describe below steps to format hard drive and install xp
First download USB_MultiBoot from boot land forum or msfn.org and extract to a new folder without spaces.
2.Turn off UAC.I mean user account disable that is adminitrator
For this you need to click start and then run
In the box type msconfig and when popup box opens click system configuration and then click Tools tab.Scroll down and look for disable uac protection.highlight this option and click ok
msconfig-uac
Now you have disabled user account off.
Go the folder where you extracted files and open it.From that folder right click on usb_multiboot.cmd and run as administrator.once the command prompt started and follow the steps with screen shots

Once you followed the steps and if their is any problem then look the boot.ini
I got the boot.ini problem because it always tried to boot from the other drive but i changed the values of rdisk and partitions and it worked.
And for the lenovo y410 xp driverds their are some roubles afterinstallation since the mouse pad dont scrolland their are even few more issues with this.So please think before and delete your partitions etc.
My suggestion is never delete the hidden partition this can help at any time to recover vista or else you need to pay the money

Tips to save battery life
1.do not over charge the battery or discharge.
2.never short circuit the terminals.
3.dont leave the batteries alone keep charging even they not in use like once in a month
4.before buying look the cells when they manufactured since it life cycle would be ending even they not in use.
5.Test the batteries voltage when you bought them from shop and their full discharge time.
6.Never use fast charging methods unless it would be tested by a experienced technician
Their are many more things that we should remember during buying or replacing etc.Just think a normal cellphone it will give more hours when we brought from the shop but from their it will start to give low hours this is a way of battery life ending.
