My current harddisc became corrupt and the machine wasn't bootable. System failure message was 0x0000007A
After a short harddisc check ( F12 while boot sequence) it showed me - fail error 7 or something like that.
With the Windows disk in the DVD drive i was able to run the DOS prompt and to command chkdsk /r. After this was done, it showed me the message: one failure found and repaired.
I restarted the machine and it worked again.

1. Next days i will get a new harddisc, because me still have a warranty for my machine. Will it be absolutly necessary to exchange the harddisc with the new one, or will the current one work after chkdsk repaired the failure? I will exchange. Just want to know.
2. As soon as i have the new harddisc and Windows XP SP2 installed, will it be easy to connecte the old one with the new one to copy all important files from disc to disc? I have two harddisc slots and two sata plugs.

Thanks in advance
