I have a st980825as that is doing something a bit strange.

I can plug it in and read sectors (using hdparm) for around 30 seconds to a minute. after that time any sector read results in an IO error. I can then remove power, replug, and read sectors again until that time passes.

Ive been able to recover about 500MB of the 80GB (using DDrescue), but this method is not really viable (unless its the only option)

the drive does get hot, but even cooling it with a fan make no difference to this process.

My initial thought was failing head, but the consistency of this has me questioning that.

I have not yet hooked into the UART to see what what it is saying.

Possible that this is a SMART or drive cache issue?

I had something similar, a long time ago(v long time)..
when without a hardware imager, or wanting to change the heads, MTP and manual switch inline to the drive did the trick.
But i wouldn't go that way now..


if data is important,take pro help, should not cost much.

else
a) rule out PCB issue
b) check terminal output

""
not usually

Sounds good. I was thinking of going that route if need be. Put a switch inline to be able to toggle power on and off and just go about this the long way. At least its only 80GB ha

What is MTP, not familiar with that?

I am going to check terminal output today, i have to imagine whatever is happening will be shown (if only cryptically) in the terminal output.

OK, so terminal spits this out

check with another PCB(rule out PCB issue)
Does the drive clicks or makes unusual sound after the "30 seconds to a minute of proper reading" ?
if so, (and if data is important) chances are that you will make the problem worse trying to clone it

in my case, it was a head issue, as i found out later(after recovering the data , i tried swapping heads to know the cause)

no noises or anything unusual.

I suppose i will have to obtain a donor drive to try pcb swap.

My research shows that i may be suffering from something called the "Pending Bug" that was common on drives of this era.

Can anyone with experience with this bug confirm that this is the case?

If this is not the case, my other thought is that the CERT is not being read correctly, as i do on occasion get this message
INVALID Cert Disk code - ROM resident Revision required : 3.04

Hello,

yes, it is a bug in the fw and can be easily recovered with proper tools. I recommend contacting somebody near you, there are several guys on this forum from the US. Where are you?

I have seen some terminal methods of resolving this bug, as well as using a loader file. I do not have proper equipment for the loader method.

Opening up to quotes from forum members.

Thank You

Could we see a SMART report?

https://crystalmark.info/software/CrystalDiskInfo/index-e.html

Do your Niwot errors show different numbers in the C.H.S position?

Q AT Er 00 Nwt Er 43 RdWr 00066.03.0043

I expect that these three numbers would be the CHS address of the read/write error, in which case it would appear that there is a problem with head #3. Conversely, if the errors show up on all heads, then this could point to a PCB fault.

BTW, you might like to try HDDSuperClone:

http://www.sdcomputingservice.com/hddsuperclone

IIUC, the following error would suggest that there is a problem reading the System Area on the platters, which would in turn point to a problem with head #0.

Here is something you could try ...

Maybe a stupid question, but since this is a firmware bug, can i flash unaffected/fixed firmware to the SPI chip? I do have such a programmer, and can easily do so if firmware is available.

No, the majority of the firmware exists in the System Area on the platters ("discware"). Only a small portion resides in flash memory.

If we are talking physical heads, is it even likely that a 2.5" 80GB drive would even have 3 heads?

But the OP's drive comes ready and is able to read the user area, so ISTM that the "invalid cert code" error must be intermittent ???

_________________
A backup a day keeps DR away.

The CERT error happens when i press Ctrl R

Otherwise this error does not occur.

Due to this error (which is consistent thus far) no commands can be run. I can only passively monitor terminal messages.

I can absolutely read data from this drive. And i can read data from different sections of the drive. The ~1GB i have recovered in laborious ~40MB chunks does appear to contain files i attempting to recover. I say this because i thought it may be just writing 0s or something useless, but not the case.

Thats what has me super confused. How can it be becoming ready and readable if that part of the firmware is damaged/unreadable.

^R tries to restart the diagnostic monitor and load the appropriate overlay (CERT) from the disc. IIUC, Spildit is saying that this CERT module contains the code which is required to support the terminal commands.

_________________
A backup a day keeps DR away.

yes, CERT is not required for the drive to work in normal mode.
Moreover, it probably was able to read CERT, but it was not compatible with rom version (perhaps fw was upgraded?) or some other error prevented loading it correctly (i have seen that too as far as i remember, but it was years ago...).

It is not impossible you will get your data off the drive, but if there is some surface damage (which is probable), torturing the drive can make it worse.
So if you are considering contacting somebody with tools and knowledge, it is time for that i think.
it's about saving 2-300 bucks or loosing 2-3 times more (risking an overall chance for recovering the data at all).

I have been trying to find a firmware update for the OP's SATA model, but all I found was the 3.07 update for the PATA version. In any case this update appears to incorporate a CERT component.

http://driverdl.lenovo.com.cn/think/download/driver/dr1240114069108/fwhd56.iso



My idea was to apply a SATA firmware update to the OP's drive, thereby ensuring that the overlays and ROM code were compatible. The OP could then have attempted Spildit's fix. This might still be possible if we can find suitable firmware resources.
