Horrors. I setup a raid using /dev/sda and /dev/sdb. Within a couple of weeks, sdb failed with a repetitive clicking sound. I immediately turned off my computer and shipped the thing back to Seagate, and they sent me a replacement. Now when I print the partition table for sda using fdisk, it says:
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
Evidently I didn't follow the procedure to "fail" the bad drive, and now I can't figure out how to retrieve the information on the good drive, /dev/sda.
Anyone help me out of this jam?
Oddly enough, the replacement disc shows that it's already partitioned.
