Hi there, until yesterday I had a working SATA HDD (Seagate Barracuda 7200.11 ST3750330AS, 750GB), it worked fine for more than a year (on the new machine and on the old one it worked for 3 years) and then out of a sudden I click on the Windows Explorer and it's not there, all 3 partitions are gone.\n\nThe HDD is spinning, the sounds it makes are the same it's been making ever since I bought it. I tried plugging it into different slots, changing the cable etc.—to no avail…\n\nIt's not recognized by Windows nor BIOS, although when I restart with the HDD plugged in, the POST takes ten times longer than usually, it's stuck at "Detecting IDE drives"—it waits for 5 minutes and then displays the list of drives but the faulty drive is not on the list. But when I restart with the drive disconnected, the list stays the same but the "Detecting" part takes only 2 seconds.\n\nI took the HDD to an IT expert, he plugged it into his machine, did some testing with some utilities and said: it's firmware. The price he demands is quite staggering so right now I'm waiting for another proffessional to see if he confirms the story (he's also going to plug it to a Linux machine to try and recover the data).\n[B]\nDo you think the firmware could become so suddenly corrupted?[/B] I have the feeling that installing new firmware is just about the easiest way of having the data lost forever… so I consider this as a last resort.
