MC = MEdia cache. For this it seems like there is problem with Media Cache and you need to disable it. You can do this with system file '0x93'. After it is cleared try again, but there may be some error with the MC bitmap.

Remove MC options via 0x93 then report here behaviour.

Thanks for repling..

i did this with F command

Byte:05C1: MediaCacheControl = 00

but don't know how to edit and clear mc option thru 0x93..
Please help if you know how to do this..

MCMTFileHandler problem solved for both drives.
One got recovered.
but in other one not a single sector is readable.all sectors show uncorrectable error.

Please help if any one faced this problem.

Sounds like a translator issue. Sometimes have to regenerate translator after disabling media cache. Usually the root problem is bad sectors and it corrupts the firmware.

[friend]

already regenerated translator..but it doesn't help..
Any other possibility?

Ya but regeneration and "m" commands are slower that other same model drives..

it looks like a translator error.
but not recovered by regeneration.
Any Possibility ?

show terminal log for V40
may be you have entries there and you regen translator without talk in account NRG

Yesterday I've spent a few hours on Seagate ST500DM002 - not recognized by BIOS...
Under TTL terminal drive shows error message:

MCMTFileHandler: EXCEPTION: Failed MCMT read request

Now, I know what's going on and now my drive is recognized by BIOS, it's during sector-by-sector duplication now. I'm on a right way to recover data!

Usually when the drive shows this error, the sysfile 346 is corrupted... It's the MediaCache File. If this file is corrupted, I'm 99% sure that the surface of Your drive is in really poor condition. Be aware, that this file is a part of Service Area.... and if it is broken, there is a high risk, that more files on SA of Your drive are not readable eg: because of bad sectors. So fixing this error is a method of making data recovery possible, not the metod of making Your drive 100% healthy.

There are 3 ways to fix this error:
1. Replace the corrupted 346 sysfile (You can use one from the healthy drive)
2. Clear this file... or replace by empty file...
3. Disable MediaCache

I've found Seagate F3 Terminal Command Set: https://www.data-medics.com/forum/seaga ... -t901.html
This was all I needed to solve the problem...

There is also another tutorial how to use r and w comands using HyperTerminal
http://www.hddoracle.com/viewtopic.php? ... e5853836e7

I will not give You the "ready" answer, because You need a little knowledge to do this. Otherwise data on Your drive are in danger and it will be a better idea to give the drive to professional lab...

So:

- TIP for "1": You know, that file 346 is a problem... Use r and w commands under terminal to replace the broken file with good one... (second tutorial)

- TIP for "3": There is F command which lists and modifies drive parameters. Please read carrefully Seagate F3 Terminal Command - there is no "ready command" for this fix in this tutorial. Look at value of 05C1 byte - giving it the "00" value is the solution - disables MediaCache. You have to re-power the drive after this change

At Level T, execute the following command:

F"MediaCacheControl",00,22

The "05C1 byte" may differ between firmware versions, so it is probably best avoided.

Thanks hpw333 for your support .

Would you mind to share the sollution ?

Well,
When You Learn a Solution You Are The One Who Public Domains it In The Entire World .You Need To Know And Appreciate the Fact That Everything is Not For sharing in Public Domain .

All the entries in NRGlist were fake, so in this case it was probably enough to clear that list.

There is no general solution for 'partial access', one has to identify the problem and take care of that. People think that DR is about pushing buttons, i guess they will never change their mind but who knows...
