Hitachi Hard Drives - Which one is for me?

[longfellow]

Mine is T42p 2373KYU which has 7K60 and want to upgrade it to 7K100. While checking in Hitach GST site, I came to know there are 2 drives listed as 100GB drives. They are: (1) 7K100 under which the model no: HTS721010G9AT00, 100GB, ATA and (2) E7K100 under which the model no: HTE721010G9AT00, 100GB, ATA are listed. Could any one tell me the difference between these 2 drives and which one I should go for? Thanks in advance for your feedback.

I see you found your answer in the other thread "7K 100 HD" on this forum.
