Hi - I have a Seagate ST2000DM001 which suddenly is no longer detected in BIOS. Drive spins and I think I hear heads move at spin up and spin down (power off). No clicking, no previous errors.

Professional recovery costs are beyond the value of the data so I'm looking for a DIY solution.

Suggestions as to what maybe wrong and what I will need to fix it are appreciated. So far I believe I need a TTL adapter to access the terminal - any suggestions for the TTL device?

Thanks.

can you show us log from TTL adpater?

Hi - not before I have purchased one - can I get some advice on what TTL adapter to buy?

Will this work?

Images suggest it has Rx Tx and 3.3v

Spin down (power off) is 99% likely to be a heads failure.

No DIY, sorry

even if you were a pro, seagate DM series is a nightmare even for pros and you end up with changing heads 2-3 times "at least", so it's still gonna be beyond data value.

The only DIY solutions I can offer is to fix the drive, but lose the data. There are two methods:

1. Contact Seagate to RMA the drive
2. Buy a new drive and throw this one in the trash

Sorry but I'm confused as to the attention regarding my comment that I think I hear the heads move when the drive spins down at power off. All drives park the heads when the drive is powered off do they not?

The point of my statement was to suggest that I don't think the heads are stuck.

Sorry, I didn't read it like that, hence the reply.

You put "spin down (power off)" not "spin down on power off" so I read it like you thought the heads were powering off.

So you're saying it stays powered up with no untoward noises, and stays spinning?

Hi - sorry for the confusion!

I've got the TTL adapter and can get a "F3 T>" prompt. What now? is there a status/diagnostic command to start with?

No need to send any commands. At least not at this point.
Leave the drive powered off connected to terminal. Then, power on and the drive should begin outputting stuff in the terminal as it goes through the initialization procedure. It is this section of messages that we are after. Copy the entire output and post it here in the forum.
A more clear description of what the drive is doing exactly while the output carries out is beneficial in order to get a better understanding of the correlation between physical behavior and terminal messaging.

Thanks for the assistance:

First time I carried out the power on while connected I got the following:


¦p
Trans.

Spin Up
SpinOK
TCC:0019

(P) SATA Reset

second and third time I got:

¦¦¦¦Up
Trans.

Spin Up
SpinOK
TCC:001C

(P) SATA Reset

so TCC code changed ... fourth and fifth time I got TCC:001D. No other output; wasn't sure if there should be!

So far, looks like a firmware issue. But, I would test more. Check smart, heads condition, defect lists condition, etc.
