Hi guys I'm after your help, I recently set my computer to do a defrag, all seemed to be going well so I left it whilst I popped out to do some errands.

Came home and it had restarted itself and had stopped at the black screen stating:-

Status: 0xc000000e

Info: The boot selection failed because a required device is inaccessible.

Noticed my SSD is no longer showing up in my bios just my main HDD. Is it likely it has died it is only just over a year old, several people on here helped me suggest a spec when I rebuilt my computer the other year, this Crucial SSD was one of the items recommended at the time?

Or could another issue of caused the problem?

It is possible you have killed your SSD, you are only supposed to use the SSD makers own software tools (or a good 3rd party's SSD tool) when de-fragging a SSD.

 

You can pop it out and see if another PC can read it or not; if it can, it is just the drivers for the SSD have been damaged/deleted/moved by the defrag, so reinstalling them should give you your system back..

There's pretty much no benefit to defragging an SSD and it will just reduce its life span anyway.

If it's not seen in the BIOS it sounds like the drive has failed. Warranty time.....

I don't see much benefit from defragmenting modern file systems on any type of drive, let alone SSD.

As for the OP, I would try booting from something like SystemRescueCd and using smartmontools' smartctl command to query the drive's SMART status if possible. But, as said above, if the BIOS is unable to see the drive, smartctl is unlikely to work either. But maybe it is just a connector that came off or something like that - worth checking too

It's showing under the memory tests upon initial startup but not in the bios listing.

Sounds like the defrag may have killed off some of the sectors containing windows, hence no boot.

I'd try a reimage myself and chalk this up to experience...

No, try going deeper into the BIOS settings, it can be just a glitch within the BIOS.

 

It's happened to me I have a Gigabyte Z77X-UD55H Wi-Fi board within my scratch built machine and once every so often it will "lose" the SSD drive, but it's still there and functional.

 

Experience tells me that I just need to check the boot sequence.

That also implies a faulty SSD. The BIOS will not lose devices as long as they are functioning correctly. If you look at the above screen shot, S.M.A.R.T status is bad - that is almost certainly down to duff sectors, no two ways about it.

You shouldn't defrag solid state memory.

if your getting a 0x message it means the device is still at least partially readable, unless your boot partition is on a diff drive.

 

Also, if your SSD dissapeared from the bios, the boot order may have changed.

 

Is it windows 7? - try booting off the DVD and seeing what it can do.

When a similar thing happens on my PC, i usually have to go into the bios and check the boot order of my hard drives. somehow the BIOS has a "Moment" and sets the SSD to last in the list.

You can't defrag the data within the memory of the SSD even if you wanted to. The wear levelling basically dictates that the file systems view of the data is entirely different to how it's actually stored.

Defrag software usually works at a low level and doesn't understand the wear levelling tables. A Crucial SSD such as this one would have a different wear levelling algorithm to other manufacturers.

As previous members said defragmenting BIOS is not an option, HDDs and SSDs work completely differnet and SSD drives don't need defrag.

Other than that one defrag can't damage SSD, so most likely it is still alive, and boot priority is most probable couse.

If that does not help try to connect only ssd without any other drives, and the last option is to reset CMOS.

Never defrag an SSD, the resulting writes will kill it, most OEM packaging has warnings advising against this.

 

There is nothing to gain by a defrag of an SSD since it has no moving parts.

 

Your SSD is most likely toast and will need to be replaced.

It's showing under the memory tests upon initial startup but not in the bios listing.

If that's the SSD on Sata Port one, then it is dead and must be replaced. There is no way at all to recover data from an SSD.

A defrag does normally kill an SSD - it just scrambles it.

You need to do a firmware update (to ensure it's not been scrambled too) which will also erase all the data. For your crucial v4 see http://www.crucial.com/support/firmware.aspx

SSD drives can show as failed in the SMART data even when brand new and functioning, so don't take that as gospel

It's down to how the values to some of the data have been set (Spin up for example).

I've seen plenty of BIOS lose a drive and not boot, so it could well be that you've found an old boot loader on a HDD and you just need to set your SSD to the boot drive.

On the issue of defrag on an SSD, yes it's fairly pointless, but then most decent file systems don't need defrag any more.
