We have been using the SSD 530 for a while now in some production units. Now i have 4 drives that have failed during a short amount of time in 4 different systems around the world.
The system compailns about bad superblocks on our RW partition (sda7) when trying to boot linux. (same error on all failed drives)
I have checked the drives with intel ssd toolbox, and it reports healthy drives. But when trying to do a scan for errors it fails on 15%.
We have not had any problems with these in the past and have not had any changes to how our file system is built for the last 3 years. We have 100+ systems with intel SSDs around the world and most of them never had any problems with the SSD.
So i am suspecting a problem with the batch of drives we got for our last buy. And i would like to figure out what is the root cause since we have 25+ systems in the field with drives bought in the same time period.
Serial numbers for 3 of the drives:
Any feedback are welcome.
We understand your situation regarding the Intel® SSD 530 Series.
It seems that this situation could be related to corrupted files on your systems.
We advise you to perform a low-level format on the system using the following command:
"hdparm -I /dev/sda"
Please let us know if that works.
That hdparm command does not do a format. It reports the status of the drive. And the 'a' in "sda" depends upon available drives (see GParted).

I have not gotten around to try to repair the I/O using HD-parm yet. I will try to see if I can get them back running without formatting the drives.
The linux system we are using consists of 5 partitions, where only one is r/w accessible. This r/w partition contains only logfiles and config files for our systems.
I could of course format my drives so I can reuse them, but that would not help with the issue long term. I need a solution that prevents this from happening so that we do not have to ship systems around the world for repairs.
We are running Ubuntu 10.04 server with kernel 2.6.32-41-generic-pae on our systems.
Thanks for the update. We would like to confirm the following information:
-Could you please let us know how did you run the scan in the systems since the Intel® SSD Toolbox is not compatible with Linux*?
-Do you have dual boot partition with Windows*? If so, please share the smart details of 2 of the drives and let us know the Windows* version you are running.
I connected the drives to a Windows computer through SATA to use the Intel SSD Toolbox.
Find the smart details below, also attached .csv of the smart status:
Thanks for the logs provided. It seems that the 2 SSDs are fine based on the information.
In this case we recommend you to perform a low level format in one of the SSDs in order to check if that helps.
Look at the raw values of BB Uncorrectable Error Count. This attribute means there have been catastrophic errors while the controller reading data from the NAND flash. The cause of this is very likely a firmware bug.
We want you to know that the only way to remove the password is to contact the person that set it up and request it. Otherwise, there is no way to reset it or remove it.
