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.

Following up on the comments; you can boot from a Linux-based bootdisk and try to format the disk in FAT32, EXT3 (or 4) or HFS(+). HFS needs you to first load kernel extensions tho, which might be a hassle. FAT32 will suffice as the OSX installation tool will force HFS+ Journaled again anyway :)
