I'm not sure that devices will be allowed to cross the border. 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?einstein9 wrote:Always wanted to try this on SSDs...
Do you sell those SSD`s as its?
Will buy few (if you are selling separate pieces not all of them) for our research

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.
