Hi all,

 

Recently replaced a 4TB WD Green with an 8TB Seagate, the data rebuild has so far taken 2 days and is 67% done. This seems to be taking far longer than other posts on here suggest it should. Although I didn't use the preclear utility to test the drive, I did run 3 extended tests in Data Lifeguard before swapping the drives. SMART data is as follows (full report from diagnostics attached):

Several of the error attributes look sky-high, but I believe this can be normal for Seagates...

 

Thanks,

SMART looks fine, diagnostics may show something.

Full diagnostics attached.

 

Thanks,

HP Microservers (at least gen7 and 8 ) come with write cache disable in the bios, you need to enable it and speed will increase greatly.

That looks like it's running much faster, thanks for that. I'll keep an eye on it, strange it's not been an issue before though.

 

Thanks,
