What am I doing wrong? More about : dell 4550 mosox September 3, 2010 5:39:55 AM Are those new HDDs? If yes you need to format them in order to bee seen in My Computer. Control Panel/Administrative Tools/Computer Management/Disk Management/ You should be able to see the new HDD in there, right click on it and format NTFS (only if it's a brand new HDD - that will erase everything existing on the HDD). If the HDDs are not new you can see them in your BIOS at least? Can't find your answer ? Ask !
