Hello, I bought a hard drive. I installed the hard drive

Western Digital 500 GB 7200 rpm SATA3 WD5002AALX 32M Black on my iMac which no longer worked. Sometimes I see the hard disk in the utility on the Starter CD, but access seems very slow. By cons when I want

install OS X 10.4.2 on the hard drive, I do not see the disk. What is the problem?

Have you confirmed if the drive is compatible with your system?  The original drive was also 500 GB or less capacity? I suggest you to contact Apple to check if this model is compatible with your system.
