My dell latitude's internal hard disk is dead. It was ATA -6 harddrive. Dell offers 80GB for 100 bucks. I find that Seagate 80 GB ATA available for $55 at newegg (Newegg.com - Seagate Momentus 5400.3 ST980815A 80GB 5400 RPM 8MB Cache 2.5" ATA-6 Internal Notebook Hard Drive - Laptop Hard Drives ).Will this harddrive be OK for my laptop ? Thanks
