You have two separate questions.
1. I have a Quantum hard drive which got a burn on one of it chip on the green part it is from an IBM aptiva 95 all of my data is on it .
Unless you can find an _identical_ hard-drive, and disconnect the electronics from that disk-drive, and then connect the electronics to your hard-drive, your data is "lost". Or, find a "Data Recovery Service" -- for a large fee, they will repair your disk-drive, just long enough to burn a bunch of CD/DVD disks to hold all the "data".
2. I have onother that I have accendentally delete one of the partition which is the C drive
Download the "Partition Tool Editor" by the PowerQuest PartitionMagic people (now owned by Symantec):
ftp://ftp.symantec.com/public/english_us_canada/tools/pq/utilities/ptedit.zip
Unzip the file, and, while the "accident-prone" disk is connected ot your computer, run 'PTEDIT.EXE' to change the Partition Boot Table, to "undelete" the partition. It's *NOT* a tool for "novices" -- think carefully before making any changes to the Partition Table.
