Seagate ST34348A Data Recovery Details
Seagate drives fail and the ST34348A is no exception to this.
   
I'm having trouble getting my Windows NT 4 system to boot. I get the following error:
STOP: c000021a {Fatal System Error}
The Windows Logon Process system process terminated unexpectedly
with a status of 0x00000080 (0x00000000 0x00000000).
The system has been shut down.
It then performs a memory dump, and reboots itself.Seagate(ST34348A model).

Seagate is the world's largest and oldest manufacturer of computer hard disks. The company has been going from strength to strength with its $1.9 billion acquisition of rival hard drive firm Maxtor in 2006. Segates flagship desktop Barracuda 7200.11 drives, in particular the 1TB - ST31000340AS units, are failing at an alarming rate and prompting outrage from their faithful clients. A new self-bricking feature apparently resides in faulty firmware microcode which will rear its ugly head sometime at boot detection. Essentially the drive will be working as normal for a while, then - out of the blue - it’ll brick itself to death. The next time you reboot your computer the drive will simply lock itself up as a failsafe and won’t be detected by the BIOS. In other words, there’s power, spin-up, but no detection to enable booting. We have the fix for this issues without the need to open the drives up.
Common Seagate Hard Disk issues include, Seagate Momentus - can suffer premature media damage; Seagate U series - can suffer motor damage; Seagate Cheetah - Firmware corruption is No1 issue; Seagate Barracuda - Suffer from firmware, motor and read/write head issues. Initial symptoms of disk problem was a grinding noise, then blue screen, then won't boot. Pulled drive, connected directly to another PC with USB appliance, ran chkdsk /f. When it first started, chkdsk skipped a few, apparently readable, sectors, but it has been running most 24 hours now and is reporting every sector as unreadable. It spends about 20 seconds trying and then goes on to the next sector. This is looking like the entire disk. Drive is Seagate(ST34348A model).

Seagate hard drives are vunerable to a power surge or spike. As is the case with other hard disk's Seagate drives controller board is usually the weak spot that will fail. The controller board of most drives stores unique adaptive data that can only be associated with the drive that it was originally a part of. In other words, it's very seldom that you can just swap out a controller board from one drive to another and get the dead drive functioning again. In more cases than not the spindle motor controller driver (SMOOTH chip) on the logic board gets burnt. If this occurs the computer would shutdown completely, you would also normally notice a burning smell and when powered on the drive will not spin up at all.
If a drive is not spinning at all this can mean that there is a seized motor or indicates possible platter damage. Data recovery in this case involves opening the hard disk in a clean facility to work on the drive internally.
I have a Small biz server with internal adaptec 2120s SCSI raid 5 config(3 x 68Gb Drives - no hot spare) serving 10 companies with 200 users so it's crucial to keep this server going!
Failed drive in 2 year old array so replacing all 3 disks 1 at a time and rebuilding the array in between obviously. After replacing 1st drive with a 147Gb (SCSI ID 01)i'm getting an AAC error in the system evet viewer of "The device, \Device\Scsi\aac1, did not respond within the timeout period".

The last typical Seagate hard drive issue applies also to all other hard drive makes and models, the problem is called bad sectors. After some period of time the platters were the data is located starts to degrade and bad sectors appear.
Whenever the hard drive attempts to read bad sectors it could start freezing, scratching, ticking and sometimes loud clicking. This leads to further damage to the surface and causes more data loss. As soon as you start experiencing such symptoms while reading important files, stop the drive immediately and consider sending it to a data recovery company like ourselves for a free diagnostic. Any further attempts to read the Seagate drive would just add up to the problems and make more data unrecoverable. In our Data Recovery Lab we use expensive imaging tools that are capable of force reading bad sectors from Seagate Hard Disks. This is usually the only way to effectively retrieve data from these Drives.
