Pls Help! Mid2012 MBPro wont format SanDisk SSD Plus 240GB

[speedkillz6]

Hello

My Toshiba HDD in my Mid2012 MBP was going incredibly slow (virtually unusable). So I purchased a SanDisk SSD Plus 240Gb from Best Buy.

I replaced the Toshiba in the main bay with the SanDisk and then connected my bootable drive with Yosemite, selected the bootable drive as the start-up disk then went into Disk Utility to format the SSD before trying to install Yosemite into the drive.

I repeatedly get the error: "Volume Erase Failed with Error: File System Formatter Failed"

I can't partition to anything Mac partitions either. I can, however, format the drive into MS-DOS without error. The drive shows GUID, SMART Verified etc...

I am not sure what to do but I can't use either drive now.

Has anyone had experience with this? I have searched all over Google and this forum but can't seem to find this particular problem. Am I searching for the wrong terms?

Any Help At All would be greatly appreciated.

Thanks!

The SATA cable could be acting up.

A failing SATA cable can do all sorts of unpredictable and funny things.

MacBook Pro 9,1 13" Mid 2012 SMC problems?

I have the exact same problem only with Samsung evo 850 250GB.
The funny thing is if I boot Ubuntu from USB flash drive (just copy the contents of ubuntu.iso to a partition on a usb flash drive formated with MBR (haven't tested guid but probably also works) partition table and file system fat32 (vfat in linux) I can partition the ssd disk with GUID partition table, make file systems, write raw data with dd to disk directly or to a filesystem like this

(WARNING commands below WILL DESTROY data on your ssd or other drive found as /dev/sda)

dd if=/dev/zero of=/dev/sda bs=4096 count=100000

or with a file system:

/dev/sda1 is mounted on /mnt/sda1 as hfsplus

dd if=/dev/zero of=/mnt/sda1 bs=4096 count=100000

I checked what it had written and the zeroed files are there. Also if I create a partition table (guid) and format the partition w/ hfsplus Yosemite installer sees it but the installation cannot start copying files (the installation stops (but not freezees) on like 20 minutes remaining and thats so for hours)

If I put back hdd which stopped booting into Mavericks/Yosemite (not sure which was there previously) I can freely partition or format but Yosemite stops (but not hangs) on some 20 minutes left and stays there forever, logs say that it can't copy the 2nd .pkg file even though the usb installer drive has the .pkg and I even tried a different usb drive- the same. USB installer works with other macs.
Mavericks on the other hand proceeds to install and then stops on 1 minute remaining and stays there. Log file is no help. And doesn't boot later.- The grey question mark.

I suspect it's the firmware (EFI or SMC) The HDD smart is ok and the ssd is brand new.
My firmware/smc:
MBP91.00D3.B08
2.2f41

MacBook Pro 9,1 13" Mid 2012

Ill try to find a sata cable to test but if anyone can point me to how to upgrade downgrade SMC w/o working OS X that be great. Apple is no help in this regard as Firmware recovery CDs seem to be only for Old macs and updates have .dmg files which I could mount/copy to USB key and try to execute from command utility from within the installer. I have the newest EFI f/w but there is a newer SMC though they are not quite "new" (2012 & 2013)

What's baffling is thet ubuntu works w/o a hitch even the copy speeds are good.
