I have a Seagate 7200.12 drive that was originally part of a network drive. This drive has never been dropped, worked fine for about a year. After not being able to access the drive over the network, I eventually removed the drive and tried connecting it via a sata to usb adapter. I have had no luck. The drive spins up fine, no unusually noises or clicking.

I have seen several mentions of fixes for this drive, but no details. Can someone please point me in the right direction?

Thanks,
Doug

Hi,

First of all, in order to proceed to some further diagnosis steps, you need to search on the forum for building a hyperterminal connection, so you can check the drive log.
After having that log, it's easier to give some further assistance.

Another option is of course to get a proper diagnosis at a DR pro.

You have to buy one or make a RS232 to TTL convertor

connect the drive and post what you see in Hyperterminal

Thanks for the input. I will do that as soon as possible.
I am comfortable building the RS232 to TTL convertor. To do so, I will have to order parts, with shipping, etc it may be cheaper to buy one already made? Can you tell me where I can purchase one?

Thanks again.

When I googled "rs232 to ttl converter ebay" I got 98 700 hits...try one of them.

I now have a connection to the drive. When I type ctrl-Z I get:
ASCII Diag mode

F3 T>

Where do I go from here?

Thank you.

BTW, my goal is to get the data off the drive. I am not concerned about being able to use the drive beyond that point.
Some additional information about the drive:
ST31000528AS
P/N 96L154-568
Firmware: CC46

In a nutshell, you don't know what the problem is, you have little idea about this "RS232-TTL" stuff and terminal, and all you know about it is from the internet, and you want (assuming it is possible) to recover data from the drive with someone else doing the diagnose remotely.... All this assuming there is a problem.

Is it ?

(usually in our stats these threads end with "data is not important / I found a backup / I just want to do it for fun/learning ... )

Have you tried connecting directly to the SATA port of a PC?
Does the system freeze or slow down ?
Does it detect in the BIOS?

Hey Doug,

Your situation strangely parallels mine (see http://forum.hddguru.com/considering-recovery-seagate-7200-hdd-t24687.html). Different firmware, and the part number is slightly different. I wish I had answers for you, but I'm at about the same place you are. We might want to watch each other's threads.

Thanks for the information!
Yes, it sounds like our situations are very similar, I too am an electrical engineer, just not an hdd expert.

I do have some different responses from the drive than you do.

When I try spin down or spin up I get "DiagError 00005014"

When I do /L then D, I get "LED:000000CC FAddr:0029EAD9" repeatedly.

Thanks again!

I finally got my hands on a desktop with SATA drives. There are two SATA drives in this computer, not in any RAID configuration. System boots, runs fine with the primary drive and secondary drives installed, or with just the primary drive installed. When I put my defective drive in as the secondary drive, the system will not recognize either drive. Can someone please give me some direction?

Thank you.

It sounds to me like the bad drive has a heads or FW problem.
