Well friends, I've tried various tools to repair my SDD but I had no success. I contacted Intel, but as my SSD was purchased as part of my laptop from Acer, Intel redirected me to the Acer. Acer has requested that I send my laptop for repair, but it would be impossible for me because of the time I'd be without my laptop. I even replace the SSD Intel for a Western Digital Scorpio Black 320GB and my laptop is working perfectly. I was very disappointed with the support of Intel! I have the hope of making a new firmware for Intel to fix the problem of the X25-M, but until that happens, I'm living:) PS.: I tried the following tools: HDAT2, HDDErase 3.1 and 4, Active Killer HDD Scan HDD LLF's HDDGuru, Victoria, and some others which do not remember ... BAD_CTX but continues to appear in the serial number.
