HD Not Readable ?

[Washac]

I put a new 2TB HD into an external bay and initialized it, when I did a restart or reboot with it connected I get this message - The disk inserted was not readable by this computer.

I then have the three options Initialize, Ignore and Eject

I am assuming the new drive has issues ?

I would not say the hard drive has an issue. I would try and put other Hard Drive in the same slot where you put the new one in and see if it read the old Hard drive or not. If it didn’t then I would consider that’s the cable problem not the hard drive but if it read then That’s the hard drive. But usually new hard drive did not have those type of problem. Because they were fully test before they put up for sale from the factory.

Or the hard drive is in the wrong format.

Tried two other drives in the same bay and all OK.

Mac OS Extended (Journaled).

Have you tested it in Disk Utility &/or DiskWarrior/TechToolPro?

Yup looked at it in Disk Utility which says its OK.

Have you tried to erased & reformatting the new HD. And check very closely what options you have.
Must be something somewhere, as the computer can’t read it.

What happens if you choose initialize when computer ask?

Thanks for the help, here is the outcome.

I shut everything down last night and removed the troublesome drive.

This morning I booted everything up inserted the troublesome drive and the got the unreadable message as yesterday, chose Initialize as I did yesterday, this took me to Disk Utility as happened yesterday, I chose the new drive and made sure that Mac OS Extended (Journaled) was selected and continued with erase. All went OK as it did yesterday but this time it mounted and asked if I wanted it to use Time Machine, this did not happen yesterday, so to finish, all is OK and what happened with it I have no idea, but good outcome

This is becoming a more common issue across many machines and I believe it is in the way Disk Utility is displaying drives to users. It is VERY important to go to the upper right menu button and choose "SHOW ALL DEVICES". Most machines default to "SHOW ONLY VOLUMES", which means some people are not formatting drives properly (or how they think they are). Also make sure "SHOW SIDEBAR" is enabled so you can see a tree of your drives.

This sounds like it may have been the cause, yesterday I was doing it under ElCapitan, today I booted into Mavericks and job done
