Disk Utility stuck around 50% when formatting SSD I bought a SSD drive for my early MacbookPro 2011, since my old HDD was very slow and with crazy IO activity when idle.

I started the Internet Recovery Mode and opened the Disk Utility to format the SSD as Mac OS Extended (Journaled) so that I could install MacOSX.

However the formatting process is stuck at around 50% and the estimated time just goes up. It is on a step where the drive name and information is gone: completely disappeared from Disk Utility.
The step is now called Partitioning.

I don't know if I should interrupt the process by closing the utility. It warns me that the drive may be unusable if I do so. 

What should I do? It has been already more than 1 hour.
Don't be afraid to restart the process with the keyboard shortcut Command+Q. The disk will eventually be formatted on the 2nd or 3rd try.
