Hi new to this site but looked thru your forum and found a couple of things like the problem i am having. HDS728080PLAT20 I have a number of these drives and a few more 80Gig Hitachi Deskstar drives and i have the same problems with them all. The drive is not seen in the BIOS and does not spin up i think they have been configured for some sort of Network or Printer product and the drive has been software configured to need some sort of command to spin up i may be wrong but just guesing.
Can anybody point me in the right directon to solve this problem i have quite a few drives and it sseems a shame to scrap them if it is a problem that can be solved.

Check the jumper settings to begin with. See the front label for reference.

Touch the drive, is it absolutely dead? Cannot hear sounds or vibration at all?

It's hard to say for sure where the only symptom is no spin and there is no other diagnostic equipment. If the jumpers are set properly and the drive is absolutely not spinning at all, the problem Most likely is the PCB is simply dead. Or perhaps the motor is seized, or perhaps the heads are stuck to the platters, or perhaps the ROM is corrupt. None of those mentioned after the PCB will you have a chance at fixing. Even the PCB would have to fail in a specific way for you to have a shot.

There is no external command to spin up. The drive needs to spin up to read the firmware and enter a ready state before it could spin back down to wait for a wake command.

You have a problem that requires a physical solution. Best case scenario there may be a diode or TVS chip you can remove from the circuit board, or perhaps dirty contacts you can clean. More likely you will need to replace the circuit board. The problem can be solved but it will almost certainly require investing in parts to do so.

If you don't have anything on the drives it might make sense to just part them out or scrap them. Even a working 80 GB drive sells for only $10-20. You would likely spend more fixing it.

@mrchumley64:

I suggest you do some research about "PUIS" (power-up in standby). That might be the cause of what you are seeing, but it depends how much of a guess your comments are, about the original equipment that these disks were destined for. Another alternative could be, of course, that they really are faulty...

Thankyou fro all your sugestions.
The jumper settings are correct and the Drive does nothing no power.
I know of someone else who has these drives and they seem to be able to solve this problem but will not release the answer.
The "PUIS" (power-up in standby) may be the answer any help with this would be greatly recieved.
And I will try the diode route as well. many thanks for the help.

If it's not a configuration problem maybe the drives were from decommissioned equipment and they were intentionally damaged , damaged , or specially setup so in normal environment they don't work. I see a lot of them.

Update for this problem:
HDS728080PLAT20, HDS722580VLAT20 i have 200 of these drives they all have the same issue Not powering up when connected to a PC. They have come out xerox machines. I have another company who has some of these drives and they can get them to power up but will not release the info which i understand. I have been given ths rpoject and i am getting nowhere. I can tesdt a signal right up to the VRAM chip and nothing from there. They have been configured for this "PUIS" (power-up in standby) i think and i don't know how to access the drive to turn this of. Can anyone help me as i am getting no where.............

I see many SATA Hitachi that do not power unless Interface cable is connected. If you apply power alone will not power.

Stupid question, but you have attached interface cable??

Agree. And I want to know the reason ?

Interface cables are connected and also tried just power and still nothing on the drive. Tried a working board from a working drive and still the drive won't spin up. Whatever these drives have come out of must give the drive a signal to spin up. Maybe the system doesn't access the drive all the time and so when it wants it a signal is sent and the drive spins up.... i just am clutching at straws at the moment.

Can fix this problem for you the cost will be £3.50 a drive


if i can help please Email me

You must be good how do you do it..........i don't think it is worth £3.50 I will do a deal how about Tony my tester you can have him and do anything you want for a day.......
