The first step is not backup of the drive but the files that you can't lose.
Once that is done you can see if a CHKDSK at boot time can complete.
I have had this laptop for 3 years and used dvds to back-up every month is it essential to keep backing - up as now in my laptop it wont do a defrag it gets to 28% in Analyse then nothing ,same as back-up it just wont back-up what so ever. I got a external drive about a year after getting the laptop and looked in to backing -up to that in 'f' drive and it did some thing trying to back-up then failed on a couple of attempts but could someone please help as this not a normal thing to happen but it does for what reason i would love to know 60 odd gig on laptop drive -c & external there are about 150gig of a 250 gig drive as over the years since 95 i have learned not to download crap as everything slows your whole set-up to a crawl ,i like firefox cos i-e-9 is just in recover page every 2 minites and far to slow and they can keep i-e - 10 . But any help people would be greatly appreciated...thanks : )
