Hi all

I have two Seagate 2tb ST2000DM001 HDDs. One with 20k hours and other with 5k. Both with CC25 FW. And a 120gb SSD to OS.
The 5k one seems like he have a sudden death.


I was using my PC normally, than I turned off the PC to clean my desk. About 30 min later I power on the PC and the Windows 10 starts without the E partition (the 5k hours 2tb HDD). Nothing on Bios, HDD regenerator, Seatools... nothing. The disk does'nt make any sound when I turn the PC on.

I have changed the sata cable and sata slot, and sata power, but nothing happened. I tryied to plug the good 2tb Seagate with cable/slot/power of the bad 2tb Seagate, and the good one starts fine.

Is this a sudden death? I'm always looking my disks status. And this Seagate was just fine. No overheating, no wrong sounds, no lag, no alerts, all fine on Crystal Disk. What can I do now? No way to RMA, it's a 2014 HDD (and sadly with only 5k hours).

My specs:

i5 2500
2x4gb DDR3
Mobo Dell MIH61R
Zotac GT 1030 LP
LiteON 120gb SSD
2x2tb Seagate ST2000DM001
 
It's dead. Drives fil, and when they do, it's sudden. One instant it's working, and the next it isn't. Disk ststus can only look at what it is doing at a specific time, and can track history to provide a somewhat predictable failure, but it isn't perfect, and the drive can fail at any time.
Replace it and restore the data from backup

Test the diode marked "QA" near the SATA power connector. Also test the zero-ohm resistors nearby. Then test the 12V TVS diode, also with an "ON" logo, located to the right of the 1R0 coil at the right edge of the PCB.

TVS Diode FAQ:
http://www.hddoracle.com/viewtopic.php?f=100&t=86
I've got about ~660 QA diode and nothing on reverse. About ~007 on all zero ohm resistors. The 12V diode with ON I've got about ~740 and nothing on reverse.
I got these values using a generic multimeter in diode test mode, I'm not a specialist so please tell me if I've done something wrong.

If it makes no noise, more importantly no vibration whatsoever to the touch, the platter motor may have seized up, but BIOS should still SEE it though.
Zero noise/vibration, doesn't detected on bios... Yesterday I've opened the HD and the platter/arm looks fine :(

Removing the cover was a bad idea. Now you have introduced contaminants which may cause a head crash. Until you did this, it was looking like a $50 PCB swap (eg from hdd-parts.com) was all you needed to do.
I was very careful and didn't touch anything. The way I opened it, I mount it. I live in Brazil and we don't have this kind of service in my state. There are actually very few places that offer this kind of service throughout the territory. Unfortunately looks like I can't do anything else more :(
 
The disc heads fly above the platters on an air bearing whose height is roughly equal to the average distance between two air molecules. A speck of dust is MUCH thicker than that.

If you still wish to try, then send your PCB to hdd-parts.com. They will transfer the "ROM" chip to a replacement PCB for you.
