Just ignore these pins. They are used to force the controller chip working under sata1 mode (legacy) if your HDD is sata2 or above. Another possible answer for these pins is TTL connector. Used for low-level communication. For example: https://sites.google.com/site/seagatefix/Home

I finally figured it out. The problem was that the SSD drives were both encrypted with Bitlocker (from being used in Windows 8.1). I still don't know why this made the entire drive(s) invisible to OSX. I could understand if the Bitlockered partitions didn't show up, but the fact that you can't even access a Bitlocker-encrypted drive to format it from ...

I just had the same problem and found the solution in a german magazine (c’t 2013, issue 12). The article describes different three ways of installing windows to an external drive. One of the ways included cloning an existing installation to an external drive - we can skip this step. Further on, it is necessary to edit the windows registry. Since you are ...

I do not think it is the length you have to worry about, but rather the thickness. This appears to be a rather thick 9.91mm drive according to specs on Newegg. There is a running list of working upgrades for your Chrome book to include SSDs here. There is one note by a submitter that using a Crucial V4: "This is 9.5mm thick. If I were doing it again, I ...

I have the exact same Samsung ATIV Book 4 with the exact same issue, and I was able to find help on Samsung's site. Most SSDs available on the market today are designed for SATA 6Gb/s (SATA 3.x). Many consumers still have older machines, however, which do not have support for the latest SATA revision. Fortunately, SSDs are backwards compatible with ...

Does it make sense to buy the pro version, since the SATA controller is kind of old? The SATA controller is really not a factor in choosing between the Samsung 840 (Basic) and the Samsung 840 Pro. As this article explains it, it boils down to the lifespan of the drive itself based on the type of NAND flash memory the drive uses which is basically TLC ...

Ignoring the specific models in an answer since those will get outdated. But in generic terms it mostly depends on your budget and on future upgrades. Any reasonable SSD is going to make a world of difference compard to a HDD. Using a more expensive (and assumed faster) SSD only makes sense if: You absolutely need the extra speed (not the case in an old ...

is any windows software that can perform RAID on different type of drive technology in a single computer? Yes, there is. It is called Microsoft windows (as in the OS itself). E.g. see this screenshot in Windows 10 preview (though it works the same in windows 7. But I have no mixed drives there to test it with). From my understanding, a ...

Try to add an admin password to your bios, reboot, enter bios and enter password. It's weird, I know, but some bios works this way. You should be able to access some more sections. If not, then do a bios upgrade. If it still doesn't have that option, then you are out of luck.

Plain and simple: No. The BIOS must support it. If it doesn't you are out of luck.

click the following icon under Drives, and you will see the hardisk speed and mobo speed : (1) OCZ-VERTEX4 ----- 6GB/s @ 3GB/s ...meaning speed downgraded to 3GB/s due to mobo limitation (2) WDxxxx ------ 3GB/s @ 3GB/s ...meaning speed fully maximised

As Hennes says in his comments, copying files is not enough. You need to perform a complete disc copy, sector-by-sector. Only in this way will you get all the files copied, including those that are locked during normal Windows operation, and ensure that the 8.3 file names are the same in the copy, since some registry settings unaccountably use these names ...

I am you and have recently bought two new adapters, one from a Chinese supplier through ebay, and one adapter from Startech. I repeated the tests, with the following results. On the Chinese adapter, the results were the same as with the previous adapter, in particular: - SMART unavailable - bad blocks detected - worse read/write performance (including worse ...

I do believe it is correctly set. "AHCI" is the driver used for SATA, and IDE Legacy mode, meant for older OSes is switched off. You don't need to do anything at all. As an aside, Samsung has a utility package for their SSDs called magician that will walk you through any changes you need to make to improve performance

Go ahead and change it now. Change it in the BIOS and registry using the information provided in the MSKB you cited. And welcome to 2014... IDE for your primary drive is so yesterday. ;) Once you have done this, upgrading to Win 8.1 should be much smoother for you. Taking care of this now will eliminate a major variable during the upgrade process.

The Crucial MX550 / 512GB SSDs are incompatible with the AMD 990FX chipset / AMD SATA RAID controller. I returned them and will research what high performance SSDs will work with the controller. The rep at Crucial was honest and said they had no time frame on a firmware update.

It is possible to boot from a USB-device. It's quite normal and very handy for installing and trouble shooting, but I would NOT recommend that solution for a system drive. - External SATA is a much better solution. Even though USB seems just as fast (on paper), the buffering, "lack" of real-time and stability will slow it down. External SATA acts exactly ...

I want to install ubuntu on external SSD and use it as my primary OS and I want to keep my windows 8.1 on my primary HDD in computer for gaming and other stuff. Unplug your internal hard drive, plug the external ssd in, and install Ubuntu to it. In your UEFI change the boot order to boot from removable devices before hard drives. Now when the external ...

The problem with the drive may be due to corruption of the partition and/or files involved in booting. I wouldn't replace the drive without first doing the following: Since you can access the drive from another Windows installation, first copy off any data you want to save. Next, run diagnostics on the hard drive (search the Internet for your drive's ...

If your BIOS supports different boot-devices, connect your SSD via eSATA and install the Ubuntu OS. Consult your manual how to select the boot-device at startup

As far as I know, there's no way to get Windows to recognize a USB device as a boot device. Even if I'm mistaken, flash memory has a max number of read/write operations that it can perform before going bad. You will almost never hit that ceiling during normal operation of a USB device, but as a boot drive you'll hit it pretty quickly. What you're looking ...

First I would use one of the SMART tools to look at the drive self diagnostic errors and see if there are any indications of the drive going bad. This stands for Self-Monitoring, Analysis, and Reporting Technology, and can give you some insight into. Possiblenhardware failures. Another specific tool worth mentioning is SpinRite which scrubs the whole drive ...

I've seen a few 4Kn SATA drives working in the hard drive validation industry, but I wasn't aware they were shipping any to customers, due to the limited hardware and software support for them and lack of customer demand. There are two competing mappings for physical vs. logical sector sizes. The Long Logical Sector feature allows a device to have logical ...
