We understand you're experiencing some problems with your Intel® SSD 320 Series suffering from the infamous "8MB bug".
Since you're already using the latest firmware version for this SSD, there's not much troubleshooting that may be performed. You could try to low level format the drive, but I don't want to give you any false hopes, there's only a low chance that this will bring your SSD back to life.
The 8MB issue may be caused by a voltage irregularity, or unsafe shutdowns, causing the drive's controller to become faulty. Sometimes a firmware update or a secure erase can help reset the controller, allowing you to access the full storage capacity again. But there are no definitive fixes. More over, this product was discontinued back in 2013, making it a "legacy SSD". While our support team will be able to replace the drive if it's still under warranty, our engineers no longer work on providing new firmware updates or fixes for "end of life" products.
Firmware version 4PC10362, which was the last version published for this model, was created specifically to address the Bad Context (aka 8MB) error. However, these earlier solid state drives where still more susceptible to voltage irregularities and other such issues than recent models.
If you're able to have this drive replaced, or decide to purchase another similar model, we can suggest the following in order prevent this issue from happening again in the future:
1. Make sure the SSD firmware is always updated. The Intel SSD toolbox will notify you if a newer firmware is available. If the SSD is an OEM drive, you will need to check with your hardware vendor for any new firmware releases.
2. Avoid Sleep and Hibernation within the Operating System if using legacy drives. The controller may become faulty and will have a high tendency to get confused. Doing so could trigger an issue and cause it to become unrecoverable.
3. Backup, backup, and backup. Even though updating the firmware on these models should fix the issue, keeping data backed up is always a good practice in order to mitigate the risk of data loss.
4. Use an Uninterruptible Power Supply (UPS). This may save the the SSD from power outages occurring. The few minutes of power allow the SSD to perform its normal shutdown, allowing for consistency as well as helping prevent data loss.
