I have a brand new Pegasus3 R4 12TB. The first time I started it up, everything looked fine, but when I started to put some files on it, I immediately got a "Critical, Major" error for PD3 in slot #4 that the disk was marked "Dead" for a bad sector or sectors. I bought a new 3TB HDD (in fact I bought two, just in case), and replaced the dead HDD. I restarted the P3 and everything looked fine; tested it all out and all seemed copasetic. I used the automatic function to create a disk array with one logical disk using RAID5, just like the original factory setup. Immediatly after the initialization was complete, I got a "Critical, Major" error that PD2 in slot #3 was marked "Dead" for bad sectors.

This seems more than simply coincidence, and I'm not going to burn another hard drive just to keep testing this out. I don't have the first dead HDD as I sent it back to Apple for a replacement, but I'm thinking about pulling this 'Dead' disk and checking it in a separate drive reader I have to see if there really are that many bad sectors on it, and if they can be repaired with one of my disk utility programs.

Has anyone else experienced dead disks that were basically DOA once a logical drive began to run on your Pegasus3, but only one at a time, in sequence? How did you resolve the issue, other than just returning the HDD one at a time back to where you bought the P3 chassis from originally? Thanks in advance for any responses.

Hi David,

If a drive reports Dead after developing errors like Bad sector or a command times out error then it has to be replaced and for further assistance, please create a web support ticket in support.promise.com and attach the subsystem report or you can also reach Promise Tech support https://promise.com/ContactUS

Hi Dr. Dave,

Sorry to hear about what happened to your machine. Have you tried changing the disk to a different slot? For example, swap PD1 with PD3. By doing this, you can probably have a better idea of the situation if it's always the third slot? Or it's always the same certain disk?

Oh by the way, as far as I know, you can only swap them while the machine is powered off.

Yu Qin, Thank you for your response.

I have swapped the drives to different slots, and the same drive showed as dead (i.e., dead drive in slot #3 moved to slot #2; then slot #2 showed up as dead drive during the next reboot. So it is the drive showing up as dead. 

I took the drive out and checked it with other drive software in a separate drive holder and it showed up as fine, with no bad sectors and perfectly functional.

Have not swapped new hard drive for "dead" HDD in slot#3 because I don't want to burn another HDD in this machine. so I've just made a 3-HDD logical & physical drive (6TB - in slots #1,2, & 4) with one 3TB (in slot #3) active spare drive, which the P3 is seeing and using with no problems (go figure) so am just using that for now). and will just rebuild the logical drive later if I ever put a new 3TB drive in there.

Does that make sense?

Now, after an OS security update, HDD #3 is showing up as "Dead" again. It shows as a Major default, but then shows just a Minor default for the drive for a Bad Sector. So I'm quite confused.

I'll have to follow the advice of Tech Support and just put in a support ticket.
