Hello,

Crystal DIsk info shows End to end error in my 1TB HDD...Values are like this 88 , 88 ,99

I don't know what that error means,but i'm experience slowness during copying and sometimes copying stucks and applications too...

I just did clean OS install but still the error exists...Is my HDD no longer good?

End to End error - This attribute is a part of Hewlett-Packard's SMART IV technology, as well as part of other vendors' IO Error Detection and Correction schemas, and it contains a count of parity errors which occur in the data path to the media via the drive's cache RAM.

First time i've seen this error before. Got this from searching around.

an end to end error flag means data loaded into the drives cache and data then written to the drive have had a different parity (basic error checking method) which likely implies a controller error

also this even though its about a SSD still applies

SMART attribute 184 (end-to-end error) indicates that the drive's on-PCB cache is going bad. The attribute is used to compare parity data between...

SMART attribute 184 (end-to-end error) indicates that the drive's on-PCB cache is going bad. The attribute is used to compare parity data between the original piece of data sent by the controller (in your PC/system) and the drive itself. This is not "bad system RAM", this is not "a bad motherboard", this is not "bad NAND flash on the SSD". It's bad cache on the SSD.

so it looks like the CASHE on the drive is going bad. never see that happen before. Yea best to back everything up and get it replaced.

yea as fzabkar said I have seen reports of it fixing it self and/or the issue not causing a problem. Its pretty much just saying - hey, There were two times that i wrote data and it didn't match up from what the Cashe said and what what written. I would backup your data just in case and see if the problem either doesn't get any worse and/or fixes it self.
