Hi, kinda new at all this and hoping I can get some help. My pc is an HP a920n, XP -SP2, Athlon 3400, 1GB Ram, 160 GB HD. I was having problems with my HD..ran Spinrite which helped, but got the "S.M.A.R.T. - BAD - backup and replace drive" message on reboot. So I purchased a Seagate 500 GB external HD and a copy of Acronis 10. Due to the amount of installed programs I have, I opted for the "CLONE SYSTEM" option.. Everything went great.. I changed my bios setup and booted from the external drive and everything works great..my problem is that my new 500 GB drive only shows 144 GB of available space, when it should have more than 300GB available.. The Acronis cloned ok..... but it also cloned the exact amount of space I had left on the original drive.... My questions are: 1) Where is the rest of my new HD space? and: 2) How do I get it back or get it to show in the drive properties? I'm kind of computer stupid so I apologize ahead of time if these seem like silly questions.. Thanks for any help anyone can provide!!
