    Failure: S3420GPV cannot handle Hard Drives larger than 2TB in AHCI Mode

      Hello,

      we urgently need help... any ideas?

      we have Problems with two identical 4TB harddisks. we use the harddisks only for datastorage, no booting. No RAID.

      Only AHCI mode!

      The server recognize the 4TB on each drive. When dataspace reach more than 2TB data amount, drive controller get the failure.

      It seems that, when we store more than 2TB on the 4TB harddrives, die GPT partitiontable changes to the volume to RAW format and the data get lost.

      We use 2 drives, we tested each harddrive.  Both drives seems to be ok. And we can reproduce the failure

      System Error log found a controller ERROR,  Disk , ID:11
