Hi there,
Receive an Intel 256GB NVMe PCIe M.2 2280 SSD, model SSDPEKKF256G7H.
HP P/N: 910595-01
Firmware: HP01
The SSD is detected by `sudo nvme list`as:
Code:
Node SN Model Namespace Usage Format FW Rev
---------------- -------------------- ---------------------- --------- -------------------- ---------------- ----------
/dev/nvme0n1 1234 010008A000001 SM2260 1 1.07 GB / 1.07 GB 512 B + 0 B 1095
The controller is:
Code:
SMI
N07T96.00
S LLUT
TW 1639 40
My understanding is that this is the Hewlett Packard OEM version of the Intel 600p series, even if there is no mention of 600p on the sticker.
Datasheet:
https://www.thailand.intel.com/content/dam/www/public/us/en/documents/product-briefs/ssd-600p-brief.pdfAs we can see, the `nvme list`command correctly returns the controller name SM2260 as "Model", a wrong capacity (1.07 GB) instead of 256GB, and a wrong serial number (unless it is possibly thus of the controller ?).
This SSD seems using an Intel modified version of the Silicon Motion SM2260 (SMI instead of SM on chip), with 256-bit AES encryption (according to the datasheet for the 600p series).
As the 1073 MB (1.07GB) can be cloned at full speed of 287 MB/s, I assume the MCU is ok and a problem with the NAND, probably the translator tables.
This situation seems quite similar to the one of this old topic:
https://forum.hddguru.com/viewtopic.php?f=10&t=38762The SSD is like the one in this topic, but visusally in good condition and without missing component:
https://forum.hddguru.com/viewtopic.php?f=10&t=40472The list of supported PC-3000 SSD Systems by Acelab includes SSD from several brands using SM2260, but not for Intel.
I didn't try a reflow, nor checking voltages so far, as a firmware issue sounds to me more likely.
Components are tiny. Measurement of voltages would be possible but difficult.
For firmware issues, my understanding is that this SSD model is still not supported nowadays. Can someone confirm?
Maybe is data recovery though NAND off still possible, but I'm not sure because of the 256-bit AES encryption.
