I have 2 hard-drives installed on my computer, but they both have windows installed. If i format 1 of the harddrives through [control panel; admin tools; computer managment] will my other harddrive be affected in any way?

Thanks!

You can only do this by formatting the one that DOES NOT have your boot sectors on it. Typically the first drive is the one with the boot sector on it. default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS <-- the id would be somewhat simillar to this.

ALso you would need to modify you boot.ini file so you would no longer have 2 OS choices on bootup.

P.S. Your sig is a little too big (Max allowed is 300x100) kindly resize it before we have to delete it.

I dont get 2 os choices at boot up. I just happen to have 2 drives with 2 windows xp copies installed on it, because the slave harddrive i use was once a master harddrive.

if you aren't booting off one, typically that would NOT be the drive labeled C:

you could go into my computer, right click on the other drive, and click on format, however its better to use a partitioning tool, as there will be a much better job, and you'd be able to utilize maximum possible space.

Okay thanks #4, that was the answer i was looking for.

I took off the harmful signature. :/

i do similar things with my computer having multiple bootable drives.

glad to have helped.
