Hello. I've got Seagate 7200.12, 500Gb, now it isn't shown in BIOS. Read a lot about CC, very similar symptoms. In Victoria and so on. But. In terminal and Putty (without any isolation or connecting read-write) it shows: RST 0x10M RW: Disk Ctlr Initialization Completed (P) SATA Reset No messages with CC. It reacts on CTRL+Z, spins well, does /U, /Z (runs and stops when commanding), clears Smart /N1 without errors, does V1 and V4. But after doing m0,2,2,,,,,22 it shows sth like this: Max Wr Retries = 00, Max Rd Retries = 00, Max ECC T-Level = 14, Max Certify Rewrite Retries = not supported User Partition Format Successful - Elapsed Time 0 mins 00 secs Zone re-format was skipped. After doing everything written about CC it is not recognized in BIOS anyway. What to do with Max Certify Rewrite Retries = not supported? Whan else can I do?
