I had 5 Seagate's ST336607LW 36GB SCSI drives in the lab. All with the same sympthoms: pcb ok, motor spin, calibrate noise ok, detect string", then after hdd name receive "Medium Error".

I opened some and the media is not sctatched. I also excgamged all the PCB's with a good working one and all of them are working.

MHDD fails badly if i try to perform a HOT-SWAP (quits in a blue screen)

I have already tried head-swap, but after sucesfully done hdd receives the same message, so I highly consider this to be SA problem.

Firmware utilities (ROM) upgrade from the vendors (both Seagate and HP) are not able to perform upgrading, because HDD is not ready.

All customers report failure after normal reboot or power failure. All tests were done in Adaptec 29160 and 2940UW.

Someone have a solution for this cases ?? I am whilling to pay or exchange for another information.

-BR-

P.S. It is nice to finally be back

Hi,

If you can find the EMOS command for Seagate SCSI you will be able to overide the format degraded condition. SCSI is top secret info so I guess you need find yourself Good luck...... BTW you can try HOT-SWAP

same error occured yesterday on our old scsi disk. after normal shutdown, medium error...

is there anything that i can do? i know topic is old but may be you people can help me.

Thank you all.

@speedlover:

I don't think it was a good plan to join a 6-year old thread, where your situation is different (unless you have 5 drives of exactly the previous OP's model), but anyway...

More info needed, for starters: Where are you seeing "medium error" being reported? Which OS? Which drive make & model? How many drives are reporting this? Just one LBA or many causing this error message? Any other errors reported from the affected drive(s)? Are you trying to say that you can't boot the system?

I couldn't give any useful suggestions without those answers. With answers to all those questions, you may get further replies.

i see error in scsi bios when searching for drives.
os was win.2000 server.
drive is ibm branded st336607lw.
i have one only driver.
i can not boot the system.
i tried to boot from live linux cds and other recover cds, but failed to see drive in that systems.
and in adaptec bios settings which i go with ctrl-a , capacity does not shown.

thanks again.

@speedlover,

seek pro help if you need data, simply replace it if you just want to restore functionality.

@speedlover:
Thanks for the info - that makes things clearer now

I expect this is not a "typical" type of medium error - the SCSI ASC & ASCQ would help to confirm my suspicions, but this:

... means that you cannot fix the problem yourself anyway. IMHO as BlackST said, you will need to pay a DR company who has suitable experience, if you want to try to recover the data.

today i give the disk to one experienced dr pro. i hope to hear good sayings from him tomorrow.

@vulcan @blackst
thanks again to both of you

good news!

recovery successful, everything back, nothing lost except considerable amount of money.
However i am happy and find a good dr expert.

Seagate drives with IBM firmware actually have fast format enabled within the Mode Pages
