Restoring Your Drive to Peak Performance

Based on my explanation there’s one sure-fire way to make your drive fast again. Formatting/deleting everything on the drive won’t work because those pages on the drive will remain full of data.

If you are doing a clean setup of your machine and want to restore your drive to its native state you’ll have to perform a secure erase. Intel distributed a tool with the first X25-M review kits called HDD ERASE. This tool will take any SSD and free every last page on the drive. Obviously you’ll lose all of your data but your drive will be super fast again!

In order for HDDERASE to work you need to have your SATA controller running in Legacy IDE mode, you can select this in your BIOS. Your drive will have to be connected to one of the first four SATA ports off of the controller.

Boot to a command prompt (I just use a bootable DOS image on my USB stick) and run the executable. Answer its questions carefully and with honor.

Tell it you would like to perform a secure erase (an extended one isn’t necessary) and when it asks you if you wish to view LBA 0 you can say no. Reboot your machine (don’t forget to set your SATA controller back to whatever mode you had it in before, e.g. RAID or AHCI), partition your drive and you’re back in business.

On a good SSD I don’t believe there’s a need to secure erase periodically, but whenever you format or re-image your drive, I’d recommend a secure erase since you’re killing all of your data anyway.

    "I'd never reviewed it" is correct. "I'd" here means "I had", it's Past Perfect tense. Reply

    That should have bolded "too" Reply

    Also, I think the velociraptor vs X-25 figures are swapped. 6 odd ms for the intel drive and 0.11ms for the velociraptor.. Reply

    Nicely written. Even a very out of practice Comp Eng understood that. Reply

    I have just replaced the hard drive in this 3 year old Dell Inspiron 9400 notebook computer with a new and very quick OCZ SSD, manually configured the partition with a 1024 offset, freshly installed the OS, freshly downloaded all of the latest and greatest drivers from Dell, and applied all currently available OS updates from Msft.

    The problem is that when the machine resumes from Standby, it will /reliably/ (4 out of 4 attempts) produce a BSOD 0xF4 after the power button is pressed to resume the machine from standby.

    Here's the sequence to recreate the problem:

    0) Machine is booted normally into Windows, and log in to an account which has administrative privs.
    1) Click on Start -> Shut Down -> Standby.
    2) See display turn black, disk I/O light flashes then stops, then the power indicator light begins to flash on and off slowly.
    3) Wait until the power light has made 2 slow flashes.
    4) Press the power button.
    5) See the Dell Bios splash screen, then disappear
    6) Boom: See the BSOD 0xF4

    The values reported after the STOP are:
    (0x00000003, 0x865b3020, 0x865b3194, 0x805d2954)

    Note that I've been in contact with OCZ before about this SSD+computer, because the previous BSOD that was produced was 0x77. Their recommendation was to create the partition with an offset with a 64 interval, and to reflash the SSD with their modern firmware. This was done, the OS was reinstalled as described, and now I'm getting a different BSOD code. Another mention was a question whether the notebook computer uses a SATA2 controller (definitely compatible) or SATA1 (which may have troubles).

    I've run Spinrite on the SSD, and there are lots of ECC errors being reported. I've been in contact with Spinrite, and they chalk this up to the SSD being chatty (which they like), but since SSD's are new and magnetic disks are common, they want to stay focussed on magnetic disks.

    When the machine boots back up, the OS reports that a serious error has occurred, and asks that a problem report be submitted, which I do. Then an attractive but somewhat generic page is displayed with common causes (Aging or failing hard disks, large file transfers from secondary media to local hd, loss of power to a hard drive, hard disk intensive processes (eg: antivirus scanners), recently installed hardware that might have compatibility and performance problems)

    Has anyone else encountered this kind of problem, and do you have any suggestions?

    As a medical student I can appreciate a well researched and analytical article when I see it. This is by far the best computer hardware review I have ever read! Thank-you for your time and effort in producing what is clearly a thoroughly researched and detailed analysis. Reply
