I have a brand new Seagate Barracuda 7200.7 40gb ATA hard drive that has some issues. Well actually only one issue as far as i can tell, you the first time i used it was in a old compaq that has ATA 33 on it but it worked fine. And then i moved the hard drive to another old system, an hp i think, and bam instant issue. First i noticed that the post was taking forever to get over with and that the hdd activity led was just staying on. Finally it continued on and i had my xp cd in drive and went to boot from it, well after it said something like "scanning your hardware configuration" it proceeded to a black screen where it stayed for about ten minutes till finally the blue xp install screen comes up , with the press f6 to install 3rd part.... blah blah blah, it proceeded to load drivers which went fairly fast but then i had to wait another ten minutes after it was trying to load the terms and conditions agreement thing, so i tried all kinds of jumper configurations, different cables, different combinations with hard drives as slaves and what not. So i just put it out of my find for a while until i needed it for an newer computer that has ATA 100 in it and same thing occurs where everthing takes about 10 times longer than it should but it works fine on the compaq. Oh one more thing dont know if its important the newer computer which is a gateway and the hp have phoenix bios's while the compaq i think has some other bios thing.
