HDD GURU FORUMS :: View topic - Micron P400m / Marvell 88SS9187 SSD

Hi, guys.
I've got 10 kgs of used SATA SSDs, pulled out from decommissioned storage array. I can't refurbish and resell them but still I may use them for my own purposes.

SSDs are Micron P400m / MTFDDAK200MAN that are formatted with 520 byte sectors. Therefore they are cannot be used directly neither by Windows nor Linuces.
My attempts to change sector size (setblocksize, sg_format etc.) were refused with "Invalid cdb parameter", the block size, I suppose. Even DCO restore and secure-erase did not change the situation.

I've got vendor firmware (not OEM) that consists of two binaries (bootloader.bin+firmware.bin) and a text file that gives me a parameters for hdparm (in fact, only obvious --fwdownload and a file name).
My attempts to upload produce the consistent results: bootloader.bin upload finished successfully, but firmware.bin either not uploaded at all (if pause after bootloader is shorter than 2 secs) or finished with "bad/missing sense data". Both DOWNLOAD_MICROCODE/"Segmented DOWNLOAD_MICROCODE" are enabled, Linux kernel lock disabled by hot-replugging the drive. I can enumerate data pages with sdparm but I don't know what to look at.

The device has open connector inside (JTAG?) and I didn't plug my protocol analyzer on it yet. Possibly a serial interface, but I'm not sure.

Could anyone give me a hint? No data on drive, so I'm free to experiment and may burn some, no problem.

We have very restrictive rules on sending information storage devices. Still we can give it a try if it's possible to send to a person, not company address. How many do you want?

I have same drive. Did you manage to change firmware ? Could you please upload that vendor firmware somewhere so I can try ? Thanks olegkirillov wrote: Hi, guys.

Hi, any news on this? I have some of them that I would like to try to use but with the 520b sector they are basically paperweight... If someone can provide the firmware I also can try... Thanks!
