|When you have an older mboard that has a main chipset that has SATA (150mb/sec burst speed) support but not SATA II (300mb/sec burst speed) support, some main chipsets will recognize the SATA II drive anyway, as a SATA drive; others will not recognize the SATA II drive at all, but in that case if a jumper is NOT installed on the SATA II drive, the bios will NEVER recognize the SATA II drive. |
That can't be what your problem is.
"This drive was replaced under warranty so I don't know if it is SATA I or SATA II."
When you get a drive replaced by sending it away after getting an RMA authorization and they send it back after a while, it's usually the exact same drive you get back, as in, the exact same drive you sent, same unique serial number, same model. In that case, if it was recognized fine previously, it should be recognized fine now.
If it's the exact same drive, it may be malfunctioning, again - that has happened to me only once, with a Seagate SATA II 500gb drive, recently. They claimed it was a firmware problem, flashed that to another version, two days after I installed it again it was malfunctioning. The drive initially was producing problems right after I installed Windows on it, on the brand new drive, I used the Seagate diagnostics, the drive failed the tests with more than 100 errors (they quit testing at that point).
By the way, that Seagate SATA II model, and another Seagate SATA II one of the same size I bought before that, that works fine, both had the tiny grey jumper that limits the bios to seeing it as a SATA drive already installed when I got them brand new.
In any case, when it is recognized, go into Device Manager, find the model of it, tell us what that is.
Check your SATA data cables. The connector on each end should "latch" into the socket on the drive and on the mboard, or on the drive controller card - it should not move when you merely brush your hand against it near the socket - if it does, mere vibration can cause a poor connection of it - use another SATA data cable that does "latch", or tape the connector in place.
(There is a slight projection or bump on one side of the outside of the connector that "latches" it into the socket - it's easily broken off or damaged)
The same thing applies for the SATA power connection.
Some bios Setups have a setting where you can set it to delay detecting the hard drives. If the bios has that, try selecting a delay.
