SATA drive shutdown

[Mordor1946]

recently bought new samsung 750gb sata drive and replaced original drive in PC. System now shuts down when booting, sometimes gets through to desktop before switching off sometimes not ! If I put original drive back in system boots and stays on....
Is it possible that a faulty HDD could cause a switch off (it reacts the same as if power were turned off ...no blue screen - no nothing),,,, anyone got any thoughts on this ??

How is the systems discs configured, is this disc the system instal?
Are you using the same sata connections?
Have you ran any utilities on the drive?

partitioned 100gb ntfs ...other 650gb still unformatted...no I have'nt tried any util on it as it won't stay up long enough...

[cunny]

is the 100gb the windows partition and a fresh instalation?

[Mordor1946]

yes its the windows partition and brand new first time format and op system load...

[cunny]

any other drives in pc?
Can you not run both sata drives together?

If you can run them both together and the 750 without the windows install see what happens then

If not

Personally i would delete all partitions on the drive, format the whole 750gb and instal windows again see if that gets you anywhere

The new drive may be drawing too much current from the powersupply.

A friend replaced a drive in the past that ran at 5400rpm with 8mb of cache and would certainly have been a single platter drive. replaced with a bigger drive that ran at 7200rpm 16mb cache and was definately a multiplatter drive this drew way more current and would persistently cause shutdowns.
He only had a 300w psu though and was already putting that under a heavy load.

More cche draws more power, spinning faster draws more power and as there was more mass to the platters spinning up spiked the current more to get it up to speed.
Then there are more needles in the drive all requiring power. all of these apparently drew too much from his 12v rail and caued shutdowns.
i diagnosed this by hooking the drive up to a sepperate power supply from the rest of the system (an old relic of an AT supply)

Ive had drives that arrived DOA and caused shutdowns, however they never even got past the POST before grinding to a halt and generaly caused power strobing (powering on and off rapidly till i pulled the plug on the psu)
