    Intel X25-V 8Mb LBA and NO_SPACE serial problem

    janos666

      I got this SSD as it is, already "bricked". I gave ~3$ for it when somebody asked for help but he did not feel like he is able to try and possibly fix it for himself.

       

      I though I am familiar with the "Intel SSD with 8Mb space bug" but it seems I wasn't lucky with this drive.

       

      First I tried to do an ATA Secure Erase with hdparm. I got very suspicios after a few seconds and it was really strange that it took about 30 minutes and nothing changed. The drive remained in high security mode, I had to unlock it manually with hdparm.

       

      As a second attempt, I tried to do a dco-restore but hdparm couldn't do that because this drive has an active HPA (about 40Gb) and thus the command failed. I could not use hdparm to disable the HPA. But I managed to set it disabled with HDAT2. Then I suddenly had 40Gb LBA space but it was unreadable. But now I could issue the dco-restore command with success. I still had unreadable 40Gb space (and theoretically right dco config with re-enabled SMART as well). I issued a secure_erase_enhanced command which took ~30 minutes again with no luck.

       

      SMART is disabled now. But it seems I can read some SMART data after a fresh dco-restre command. It says this drive has zero amount of host writes and absolute max number of bad sectors.

       

      It wasn't easy at all (the official Intel tools didn't recognise this drive as an Intel SSD which is applicable to any firmware updates) but I finally managed to update the drive's firmware from *2HD (the original factory one) to *2M3 (the lates public one). I repeated the HDAT2, hdparm, dco-restore, secure_erase with this new firmware but the result is the same: after a power cycling, the drive has 8Mb LBA space, even if I leave the HPA disabled.

       

      Well...

      Any other ideas how to bring this SSD back to life?

       

      Note that this driver has NO_SPACE serial, not BAD_CTX and the new name of the SSD is Intel Postville (the developer codename of this SSD family). So, it seems to be a different problem, not the infamous "8Mb bug" with the BAD_CTX serial.
