Hi, New here, found this site when looking up the "not recognised" 7200.11 problem. I have checked on the Seagate page, and while my drive is listed by model and serial number, my disk firmware is LC11, rather than the AD/SD group. I see in Gradius's post (19 Jan 2009) that the Seagate site says - "**Note: If your drive has CC or LC firmware, your drive is not affected and no further action is required. Attempting to flash the firmware of a drive with CC or LC firmware will result in rendering your drive inoperable" I cannot see this note on Seagate's site now (have they discovered otherwise?), and on 22 Jan 2009 (post #142) SPOOX repaired his drive - which had firmware LC15. I am reading page by page and have got to page 37 - but can anyone tell me (sooner) if LC11 drives can be fixed this way? The problem does appear to be the BSY fault; the drive had been working perfectly normally until just one day on booting up, the drive was not recognised in BIOS. It has been tested in other computers; still not recognised. If it can be revived, is there any updated LC firmware - and if so, would it be worth upgrading anyway? Thanks in advance for any advice and help, Gram
