toshiba laptop hard drive problem advice please

[craig6928]

got a toshiba drive model number hdd2190 mk4025gas

done a replacement headstack on the unit as the other was dead.

the hard drive is picked up in the bios fine now but not in windows at all.

we loaded up mhdd and the drive is seen ok
tried to a scan and repair
but the hard drive comes up with a lot of bad errors at the start

allso tried the toshiba diagnostic program

and the hard drive fails on smart

loaded up aff repair program

and it says that the drive is fine and that the firmware is ok
there is no recovery needed.

but when infact there is a problem still and there program can not pick this up.
been told on the forum to reset the g-list
but i dont have any program for doing this.

does anyone know how i can get this done online


quick qeastion when you do a replacment headstack change
do you have to kill the g-list all the time

thanks

NO, but with toshiba a glist overflow often causes the data to be unreadable. Hence erasing the glist is a good idea (after backup off-course).

It sounds like its got lots of bad sectors, these may have caused the original heads to fail. It's not uncommon to have unreadable after a head transplant. just clone the hdd with Deepspar or other cloning hardware.

commercially 1 out 3 products to choose for Imaging. If possible, acquire 3.
Deepspar
Data Compass
Ninja

Most of the time these drives have motor bearing issues which cause bad sectors when cloning, unless you read the drive very slowly.

I have done many, many Toshiba recoveries and head failure on this particular model is rare. However, bearing failure isn't.

At this point I would not erase G-List. I would transplant the heads, platters, and magnets to a known working motor and see if the number of errors diminishes. If not, then maybe wipe the G-List.

MHDD can still show a good drive even though heads dont work properly.

MHDD scans sequentially and does not really reflect how Windows would access the disk. Try a butterlfy or random scan to see if heads are stable under "real world" pressure

Totally agree. I have had many Samsung disks, and Maxtor disks of the 6V family which scan perfectly in MHDD but actually have head failure and cannot be accessed through Windows, or even PC3000

I think i'll have to disagree with you there. A sequential scan will show you where the bad areas are and if heads are functioning 100%. Clone the disk around these bad areas. Cloning software/hardware will clone disk sequentially.

I always use the desert analogy, if you are stranded in a desert and own a bucket of water (good areas of disk) and a bucket of piss (bad area of disk), drink the bucket of water first, then the piss, you might live long enough for rescue (full clone of data).

Nice anology, but if you have time to drink a bucket of water, then a bucket of piss, wont you die of starvation first??

[HDD Spaz]

you can go without food for about a month, maybe longer. you can dihydrate after 2 days.
So piss just might save your life. never diss the piss

Its ANALOGY dip-sh*t.

Please read my book - The English language and it place in data recovery.

I should make a killing with this forum and everyones bad grammar.

The Clean water and all the pee water drunk, turns to more pee water to be drunk. Leading to more potential bad areas while cloning, it's a good analogy HDD Spaz.

you seem to have a bad attitude on this forum. Do you want to know what I think? I think you just like to let off some steam, and doing it here gives you some sense of authority or knowledge. Do you want to know what else I think? If knowledge was dynamite, you would barely be able to blow your nose

hi m8 we did a transplant from a brand new toshiba drive.
drive is working but not seen in windows at all.
looks like the only option we got now is killing the g-list

[HDD Spaz]

why so so obsessed with getting the disk seen in Windows? what does MHDD tell you about the disk? Can you read any sectors?

[hddguy]

If you have the tools to clear glist, havent you got the tools to recover in a non-windows environment?

[hddhelp]

Or maybe do the intelligent thing of sending it to somewhere where it can be recovered PROPERLEY and PROFESSIONALLY.

Are you in US?

[HDD Spaz]

something wrong with your eyes? Location is clearly 'Canada.' Contrary to popular belief, this is not part of the US.
