Question

Posted

SSD isn't being detected anymore I installed win 8.1 (up from win 8) and was working fine last night switched it on this morning and the drive fails to be recognized even if I pout in the install media goto where you can select the parttion to install it to and drive not there. It started working again Cpl hours later then went out came back to turn it on and its not there again. Im sure I had some problem with it ages ago after a new win install it doesn't seem to like working for a while.

 

On one error it said something about the drive being locked... ocz vertex 2 bigfoot 120GB. I just don't get it so anyone know what it could be?

Does it appear in the BIOS? If it does, then you can narrow it down to a Windows problem. If it's missing from the BIOS on boot, then it's a hardware issue.

The Vertex 2 SSDs have a really high failure rate, so unfortunately, I wouldn't be surprised if it's dead.

Yep... sounds like "It's dead, Jim"

The SSD's occasionally have a firmware update, try to find it with the OCZ Toolbox and get the latest firmware version. Maybe this will help with the disappearing SSD problem.

 

Also I have two OCZ SSD's and have been told they have high failure rates but they've both been going strong for around 3 years now.

Has the computer been turned off all of a sudden without being shut down properly? On my m4 it wasn't recognized all i had to do was leave the computer off for 24 hrs before trying to boot up again.

I have had a vertex 2 and Vertex 3 do this to me. SSDs have a controller built into them that controls the access to the flash modules. The controllers are what is failing most of the time, and there isn't anything that can be done about it.

The vertex series has an LED on it by the data port, if it doesn't turn green at power on, it's dead.

Try using Parted Magic and reset the NAND using the secure SSD erase method. However this will only work if it is seen in the Parted Magic utility. It will also describe how to unlock the SSD.

 It also describes how to unlock he SSDSSD isn't being detected anymore I installed win 8.1 (up from win 8) and was working fine last night switched it on this morning and the drive fails to be recognized even if I pout in the install media goto where you can select the parttion to install it to and drive not there.

I had a ssd that would not show up to the bios. The cure was to leave the computer on for an hour even if the bios doesn't detect the SSD. Apparently in my SSD's case it took an hour for the SSD to reset if shut off improperly (very rare and odd case). After that it started showing up again and has ever since.

ah right ok ill have a go on that, it does disappear sometimes then I usually just unplug the other 2 hard drives and it works again. The SSD light is green and ill see if theres update firmware, especially annoying cus I don't want download 4.5GB update for BF4 again if I had to reinstall good job I got an old rubbish hard drive in here cus cant install windows to the other 2 HD's cus there formatted with GPT and don't have a UEFI bios enabled MB

This happened to me with my Force GT drive, it came back after a few tries, and then went blank. When it went blank, the ssd would not show up in BIOS as well. The problem was a loose connection of the SSD to the motherboard (the wire connecting to the motherboard was not set properly).

I tried that, and plugging it into a different port. Think ill just leave it off it'll probably come back to life soon... when it feels like it! had it for 3 years and SSD life says it has another 9 years life in it so maybe the controller is a bit screwed up

i've had this issue several times with my system. The BIOS will randomly decide to not recognize the SSD. i have to turn it off, unplug the SATA cable, plug it in and it works. who knows. ive never known why.

Don't count on it. The OCZ Vertex 1/2 were both unreliable drives. My Vertex 1 died within four months, and a few of my friends had terrible luck with the Vertex 2's. That Sandforce controller is no good in the Vertex 2. I wouldn't rely on SSD life.

another idea: check / change the power cable (try another port on your power supply)

The Vertex 1 has the Indilinx controller, like the new ones do, so it's pretty reliable.  I still have one of those in my laptop, and it's still chugging along.  The Sandforce controllers are what gave everybody nightmares.  OCZ just didn't seem to figure out how to deal with it via firmware until the 3.

Eh,  I haven't had good luck with OCZ. One of my other friends had his Vertex 1 died, in a short timeframe. I had my Vertex 1 replaced, and sold the replacement. At least their support was easy and fast (gee I wonder why), but I'm glad that company is bankrupt.

i, on the other hand, used my Vertex 1 and 2 for years w/o a hitch :wacko:

I've used only OCZ since the Vertex 1 (but skipped the Vertex 2), and I've always had really good luck.  I can't say I've ever seen a failure in the 40-50 of them I've used in builds.  I had a pair of Vertex 3s in RAID 0 for a while, and then upgraded to a single Vertex 4, which I currently have in my desktop PC.  They've always been stable and incredibly fast.  Luckily the Samsungs are priced well, otherwise I'd be completely bummed that OCZ went under.

Vertex in raid 0?!?!?! That's like playing Russian Roulette with 3 bullets in the chamber :laugh:

Vertex in raid 0?!?!?! Death wish much! :laugh:

Meh, the only danger is losing all the data if one dies, but that's no different than having a larger single SSD die.  I don't think RAID affects lifespan or anything.  File transfer speeds were insane and SATA3 was completely saturated.

 

The only major annoyance was when my Asus mobo had a firmware update, it would corrupt the RAID array and all my data would be lost. :(  Wasn't too happy about that, which is what pushed me to get the larger Vertex 4.

The thing is with a known unreliable drive, a single drive may fail sure.

But let's say the drive has a 30% failure rate. Running two of them you're not merely doubling the chance of failure by using two equally failure prone drives, you're actually more than doubling it. I don't know the math to tell you exactly how much as I haven't done that since forever, but it's basic logic math.

I had the Vertex 3, which wasn't a failure ridden one.  Especially after a firmware update.  The Vertex 2 was the bast*rd child and had something like a 5-6% failure rate according to a study a few years back.  So it's not like it had failures to epidemic levels, but that 1 in 20 people weren't happy and weren't hesitant to complain on the internet about it.

^This. The math is just multiply all of the discs reliability rating probabilities together and that will give you the new reliability rate. So in your case (1-0.3)*(1-0.3) = 49% chance of not losing data. Add another and it is 34% of not losing data.

My very first SSD was Vertex 1(Indilinx) and 2(sandforce) Both died on me :( Off late I have decided to go for Intel One's, Intel are a little expensive compared to Vertex but that's worth it. Even my 520 is sandforce based, As far as my research & experience goes, OCZ had problems irrespective of the controller. what you are referring to could be some undisclosed SF compatibility issues with the hardware manufacturers.
