Dear All, I want to marge the :D drive into :C, I need more space in C drive so anyone could tell me how could I merge the D drive into C? Thank you

Windows XP does not natively support this feature. You therefore need to use a third party partitioning tool which will allow you to perform a non destructive resize / merge. Partiton Magic is one such very good utility. However, it is not free. Partition Resizer is free. However, I have personally not used it. You may find more free versions here. ___________________________________________ ☺ When everything else fails, read the instructions.

I would ask why you can't just use the space on the D: drive for whatever you need space for? There is almost nothing that absolutely must be installed on the boot partition, other than the OS of course. IMO it is actually better to install programs on a different partition. That way you can perform your routine backups faster, as there is no need to repetively backup your programs, as they usually don't change. You do perform regular backups of some sort don't you?

If you have an extra HDD and Ghost 2003 you could clone your HDD to the spare drive and then clone it back to the original. Whne I do this, it resizes the partitions and usually give more drive space back to the C:.

If you wanted to merge non system partitions, it would be performed by using usual Windows disk management feature. But in your case you really need any third-party partition software. PM is quite good utility but personally I prefer Disk Director which is easily and more user-friendly for me.

Whatever you decide to do, back up Data you cannot afford to lose, I have seen many times where this goes wrong.

Windows disk management can not merge partitions. A volume set is not a merged partition. Windows disk management will not allow you to do anything with the system and boot partition(s) period. I would take birdlegs warning one step further. There should be NO data on d: when you merge it. In fact if you want 98% success rate using partition magic you should delete d: so the space is raw then expand c: into that area. This is after you have checked the disk with chkdsk /r and defragged the drive c: Not doing that is what causes the 2% failure imo. Understand that if you "merge" data on c: and d: you can very well end up with NOTHING but a corrupt disk. This is for sure if you don't have sufficent free disk space. Are you ready for where Microsoft wants you to go today?
