HDD GURU FORUMS

Hi all!

I have here a SanDisk Ultra II

If i atach to Pc3k i get drive DRY, i can ID (model, serial capacity and FW). After that if I try to do anything Get nothing, always BSY.
for example If i try to read secs i get BSY led ON, and can not access to data.

main chip is 88ss9189-bld2

any way in this case?

Thanks in advanced

Power the drive off, then send the command to image. Does it read any sectors before getting stuck at BSY again?

Hi luke!
are you speaking about "DD" command on linux to make SSD image?

Are you not using DE with PC3K? Are you able to give me remote access?

no, i can not read any sec

as you can see on pic

probably "Translator issue"

yes very probably.
The question now is:

Do you think will be recoverable ussing pc3K for SSD?
any other way to recover translator?

Is it possible that SanDisk's Translate Sector (87h) ATA command has been retained in their SSD models?

If so, then this may provide a way to test the translator.

and how we can test?

good luck

SanDisk CompactFlash Memory Card OEM Product Manual:
http://pdfstream.manualsonline.com/2/23ba20e9-6aaf-4f79-a7d9-f78379489686.pdf

There is a Translate Sector (87h) command on page 5-23:

When this command is issued, the controller responds with a 512-byte buffer of information on the desired cylinder, head and sector with the actual Logical Address.

Table 5-33 represents the information in the buffer. This command is unique to SanDisk CompactFlash Memory cards.

Hello, I just registered because I am at loss what to do: Sandisk Ultra II 480 GB SSD with Marvel 88ss9189-bld2 controller.
The drive has been through PC 3000 incl. direct support from Roman (ACE) and the chips warm up but no data read out at all.
Diagnosis so far: electrically dead. No answer from drive...Eprom read error...Firmware upload impossible etc...
I am looking for somebody who has dissoldered the memory and resoldered them to the same drive model and gotten the data out. Is this possible? Anybody out there? I know it means A LOT of work and am willing to spend.

If you can upload detailed photos of each side of the PCB, I can show you the voltage test points. That will help us to narrow down the fault.

I have few of these drives now in lab now. PCB scans:

Yes thats what mine looks like thanks, Voltage gets in, chips get warm. The drive was overfilled, meaning somebody was working with video, not knowing that the files were written to the system disk/usr/movies and it sort of ran out of memory, could that be?
Supposedly it started acting up and then died that same day.
Anyway its totally unresponsive since I got it. I am hoping to find somebody who successfully de-soldered, dumped and reassembled data from this model as that seems to be the only solution.

The supply voltage test points appear to be TP23 - 26.

There appears to be a load switch and TVS diode at the 5V input.

Thanks! I just got a note from ACE in Texas and they said no chance to recover this model because of firmware

Two more linear LDO regulators.

I think this is a 1.5V LDO regulator (if the part marking is AY).
