I have Seagate ST98823AS not detected in Disk management. Terminal shows the following:


Interface task reset

4096k x 16 buffer detected
MERC2 - 1 Disk S-10 12
Buzz - 01-06 14:00
Headmask 07,01 - Switch to full int


Spin ready
(P) Pata reset
(H) Sata reset
Switch to full




Any idea what the problem is.

Hello,
Switch to full int$ means head weak or some time head damaged,
it also occur if firmware not working properly

Waqas Ali

Thanks Spildit/Waqas

Spildit,

- The drive spins normally, no strange sounds.

- Yes, the T> prompt does come.

Scanning with MHDD provides: 95% less than 10 ms scan time
5% less than 3ms

Waqas,

Is it possible to test the Head, if they are weak or not ?

Greetings !
The message "switch to full int" is perfectly normal for your drive and you will get that output even on a new working drive.
You can scan the surface so the firmware is working as it should, otherwise you wouldn't have LBA access.
I'm guessing that you want to recover data from the drive. If so clone the drive and run logic recovery sofware on the clone, like r-studio.
At this point there is no reason at all to believe that your drive might have a firmware issue.

Thank you all,

I have cloned the drive using StarTech cloner.

After scanning using MHDD, the drive is now visible in Bios and Disk management. I formated the drive without any problem. But, when I look at SMART using Sediv, I can see two constantly increasing attributes: Seek Error rate and Hardware ECC Recovered; both increase by a constant amount with each refresh (irrespective of the time interval of the refreshes)

- Seek Error Rate increases by 8 numbers

- Hardware ECC Recovered increases by 3 number.

What could be the problem ?

Most problably ghere is patters degradation as said Spildit.

good job Matiw!
