no I meant the hard drive, anytime I have heard bad block was to do with hard drives, although I realise it said CD-Rom but how do i get rid?

 

You can get bad blocks on any formatted medium, trouble is in this case it could be one of many things, a scratched CD-ROM disk, a CD-ROM disc that was burnt incorrectly, a CD-ROM that can't be read because there is a dodgy DRM product interfering with the process of reading the drive. It could be because the drive is faulty and not reading reliably because of poor calibration, scratches on the laser lens etc.

The CD-ROM is by definition generally a read only medium, you can't fix bad blocks, bad blocks are fixed by altering the low level disk metadata and marking the blocks as bad, you can't alter the metadata on a read only disk.

 

Thats a very good idea.

Alternatively install this, same idea really, fresh install of an OS without any DRM crap, if you can burn it to a CD that is ...
http://www.ubuntu.com/getubuntu/download

 

no its just the one partition, i have been thinking about wiping it and doing a fresh install but my motherboard drivers are on a dvd disk and if it doesn't work my system will be caput until I get a new drive

 

You can always make another partition... Ubuntu does this for you on install automatically... alternatively use diskpart and install another XP, not sure what the windows boot manager might do though, they tend to be a bit funny...

 

The other hard disk is one partition and I am supposed to be giving it to my nephew. The dvd drive from the other comp is IDE and to be honest I haven't got the room for ribbon cables n stuff and its the wrong colour for my case.

 

do you mean set that up as the main drive and install xp etc on it?

 

What he said, prat.

 

Some people seem to think XP multiboots fine with itself on the same drive, never tried it myself.

 

I have just tried a sfc /scannow and it got to a point then said the windows professional cd is wrong files that need be copied to the dll cache can not be continued please insert the correct disk. Possible reasons are knackered disk or cd drive

 

it said .dll cache whatever that is It didn't say what the files were

 

Have just ran chkdsk on the hdd and it didn't find any hdd errors. I am getting more incline to think there is something corrupted in Windows, I have gone back to the earliest restore point I could but I think it wouldn't matter how far I went back.

I am tempted just to wipe it now, I can't wipe the other pcs hard drive until I get an extra hd to put some the content on or I could wait until I get a new DVD drive on Thursday install that then format and reinstall.

 

The dllcache is a 'hidden' directory in the system32 folder. It contains supposedly good copies of important files. There is a process that runs and checks if the working files are corrupt or not. If it thinks they are corrupt then it uses the copy in the cache to restore it.

Note that if the version of the Service Pack applied doesn't match that of the CD then things can get into a tangle. I always make sure that I have a slipstreamed copy of my XP CD to avoid this.
