Guidance

Postby jimpan » 30.08.18, 11:51

Hello everyone. Just working on my third drive with PC-3000. It is a ST3000DM001.

I have this drive that powers on and appears to Autodetect. Status registers stay BSY for around 10 seconds and then in ready state. If I leave it there around 20 seconds or so and then try to Run the utility, the drive status register stays BSY indefinitely and I get the following:

HDD ID has not been read ERROR: HDD Redyness timeout (10000). Run Utility?
It is like the drive drops off and can no longer be detected.

So I have disconnected from PC-3000 and I thought I would do a resistance test on the motor pads on the drive itslelf. With the PCB in place, I get almost 0 ohms across all pads. However if I remove the PCB, the resistance is what it is expected to be. Approx 3.2 ohms. When I test the pads on teh PCB, I definitely get 0 ohms. So i put it down to the PCB being the problem which is shorting.

Would you as a next step go and source a PCB donor?

I just want to get anyone's feedback to make sure I am on the right track as I am new to this.

Thanks.

for Seagate, you should check terminal output. also, at DSC DRD status you should check if the motor stops - Seagate drives will generally report a ready state from ROM only where heads cannot read overlays from SA - if motor has stopped probably heads are at fault.

Terminal log will help. Most likely PCB is not the issue here.

I dont understand what you mean by 'drive drops off' - unless this relates to spindle motor stopping?

Thank you for responding. When drive is in ready state, the motor is still spinning. I can tell it is for sure.
I probably should not have stated 0 ohms. It has some resistance there. But it is 0.4 ohms. It should be 2-4 ohms.
Other things I noticed. When I remove the PCB, the resistance is normal.
If PCB is on hard drive, then I get this very low resistance. But if I leave the drive unplugged for say an hour or so, the resistance returns to normal up until I plug the drive into power. So something on the PCB is causing the low resistance and takes some time to dissipate.
I am jumping on a support session tomorrow with someone from Acelab and hopefully they shed some light on this issue.
I'll report back.
Thanks.

Thank you guys. I just thought to provide an update. Tech support did help me out. Pardon my terminology, as it turned out, I had issues with the drive in the G-List which filled up and caused the drive not to become ready. Tech support did their magic stuff and got it going. I tried following along as best I could and did learn a bit. Looked complicated but the tech guy made it look easy. Once the drive ID'd, the rest was easy.

Drive had a total of 6 heads. Head 1 was pretty bad. Customer did not want to pay for a head replacement so gave him the options and risks. I did a map scan of user profile only and made a data copy. Currently just saving the data off to another drive. Looks like I probably saved 80-90% of data.

Off on a training course in Prague in October so hope to get good at this stuff. :umnik:

Appreciate your time to respond.
