Performance 3 128 GB read error...

Hello,

 

My P3 128 seems to have issues. Yesterday I noticed that my scheduled backup of the drive stops at a certain point. After some investigation I have found out that there is one or more files on the drive that cannot be read - the system stops responding with the HDD LED constantly on. Chkdsk /r does not help either, it simply stops when reaching that certain point. SMART values does not seem to reveal any problems.

 

I have read here in the forums that zerofilling the drive solves the problem, but it will come back by time. So, RMA?

 

thanks!

Thanks. I did a two-pass erase on the drive and now it seems to be ok. I'm afraid it's only a matter of time until bad blocks appear again, as I saw this seems to be a common problem with P3 series.

 

Even worse, after erasing the drive and restoring my os backup image, it shows a notable drop in write performance, check atto, 208MB/sec before, now ~142MB/sec max, multiple iterations done and the drive is aligned, using intel RST driver in AHCI.

 

Before errors and erase:

Comments from Corsair staff would be appreciated...

 

thanks

For it's mainly on the writes were you have lower rates, maybe trim process still needs some time to free written blocks/cells?

 

I have left the PC idling overnight but it is even worse today - max 130MB/sec. Trim is enabled.

 

Could it be the problem that I zerofilled the drive with Paragon Diskwiper instead of Parted Magic?
