HP is getting faster...at shipping the wrong unit. Today, I received another hard disk drive. A reader pointed out that the wrong hard disk I received yesterday is an IDE 48 pin ribbon interface--not the SATA interface that was in my notebook. And today, I received another IDE 48 pin ribbon interface disk drive, again with part number 430328-001 on it. And guess what! The bad disk drive has the same part number on it: 430328-001. This means that HP has two parts that are completely different and incompatible with the same part number.
