Attach you IDE hard disk as secondary slave to any other PC other than where it was earlier installed, then download a good data recovery software
, now the problem is to choose best data recovery software.
I have visited many data recovery websites and evaluated many data recovery softwares. but I found one data recovery software almost excellent.
As you have two OS in your crashed hard disk one is windows 98 and another one is Linux.
To recover your data from your Windows 98 operating system use Recovery for FAT and NTFS
and from Linux Operating system Recovery for Linux
I tried this software two or more times and BINGO!!!!
and get all my files back.....
Really a great piece of software.........
