Windows 7: SSD Not Recognized After Power Outage

05 Sep 2015   #11

Windows 7 Ultimate x64 SP1

I don't know if your BIOS is capable of disabling drives, not even sure if it is possible. Maybe with UEFI?
It is possible SATA operation mode has been reset with loading defaults.

So far I have read a lot of valuable info here: TR Forums ? View topic - SSDs and Sudden Power Failures

Darn, I wish I had read the above forum BEFORE I installed the SSD. It seems I could have set my PC to hibernate & this would have been a "safety feature" for my SSD. I always thought this was only an option on laptops.

I currently own the first laptop of my life. I have run PC's since the first version of Windows ~ so long ago I can't even recall what it was. XP has always been my favorite, then Windows 7. Buying a laptop was my best option until I got my PC up & running again after I broke a Seagate hard drive where the sata/data cable connects. No fixing that huge boo-boo!

I read the following statements online & am wondering what command to run or utility to perform when system won't even boot from SSD. "The good news is, file system corruptions are typically not fatal since most operating systems will perform a file system repair operation on the next power up. Alternatively, a user can run a command or utility to perform the repair operation."

I need some help understanding these terms if anyone has time:

TRIM ~ as used in this sentence: The SSD potentially has some extra issues due to TRIM or garbage collection, but it's really not much different than a conventional disk during a write operation or defrag operation. A complete brick of an SSD due to power loss is actually pretty rare and is usually due to firmware bugs.

RAM CACHING Ex 1: If you make use of the ram caching feature from the EVO range and the power goes, anything in ram is susceptible to loss. Ex. 2: Just don't use RAM caching. The EVOs are already fast.

Write-Cache Buffer Flushing: I think I had this enabled in Samsung Magician b/c it was recommended when using an SSD & HDD together. Doesn't look like it helped at all at this point.

TRIM is an SSD command to clean deleted cells. When the OS support it and it is enabled, whenever you delete data, not only the MFT index for it is deleted ( but also the cells holding that data are cleaned (

RAM caching is Rapid Mode.

I have Write-Cache Buffer Flushing un-checked.

There are plenty of us who have hibernate completely turned off with no issues at all.

The Motherboard in my PC is MSI-A75MA-G55. The manual is located here: MSI USA - Computer, Laptop, Notebook, Desktop, Mainboard, Graphics and more .

I am running Windows 7 64-Bit & have 8GB Ram. I want to update the Ram to 16GB. I normally use the Crucial System Scanner to find the correct memory upgrades, but this is a custom built gaming computer & the scanner does not work on it. I think the DIMM slots require DDR3, but I am confused about the Dual-Channel Mode Population Rule.

Since I haven't been able to get the SSD to boot, I am going to return it. Thanks for everyone's help.

Sorry to hear. Did you get the chance to try it on another PC?

Win 7 and Win 10, both 64-bit

Just wanted to share my experience and see if anyone has any thoughts.

I originally had the same problem as the OP; I had a power outage and couldn't boot from the SSD, (it just went straight to BIOS). I checked all the BIOS settings and tried rebooting with no luck. I continued to try rebooting several times over several days and eventually it booted up normally. I didn't have any more problems with it until today.

Today, I was going to be doing some work on the house with the power off, so I fully shut down the computer and unplugged it before turning off the power. When the work was done, I turned back on the power, plugged the computer back in, and turned it on. Same thing, it booted straight to BIOS. Based on my previous experience, I just kept exiting the BIOS and letting it reboot. After about five or six reboots from BIOS, it booted up as normal.

Anyone know what would cause this temporary outage of the SSD after the computer has been without power?
