December 20, 201213 yr I have a HP ProLiant MicroServer N36L with 4 identical drives in the front SATA slot. Official bios with all the settings checked. Untill now 1 of the drives is very slow during pre-clearing. I'm doing a second pre-clear on it, but it's still on 9Mb/s The drives are around 3 years old, I tested another drive and those speeds are as they should be. Here is my log file for the ones that are interested in helping me to analyse this problem - Could it be a bad drive? - Or could it be an AAM setting, does an acoustic mode have any inpact on this process?

December 20, 201213 yr Some drives have AAM settings, and they might slow things down, but others just have firmware that is slower, as they are fast enoough to use as USB drives. I have no idea how to change the AAM settings. Perhaps an argument to the hdparm command.
December 21, 201213 yr Author Seems there is another problem with the drive. HPA is enabled, this is what I get from using WHS for 2 years before I've build a small ghetto server (mobo in a paper box) and will look into the AAM, if it is enabled. If I remember correctly, then I used openmediavault for that.
December 21, 201213 yr I think there is something strange with that drive, but it's not clear just what. Be aware that modern hard drives are not perfect; but that is factored into their design. ECC is used to handle a lot of that imperfection. Hence, it is normal for a drive to report ECC_Recovered values that grow >>at a reasonable pace<<. But your drive appears to be "shouting" Lookie-Here to me: Note from your pre-PreClear SMART report: 9 Power_On_Hours 0x0032 093 093 000 Old_age Always - 34172 ... 195 Hardware_ECC_Recovered 0x001a 100 100 000 Old_age Always - 9010 and compare to the post-PreClear SMART: 9 Power_On_Hours 0x0032 093 093 000 Old_age Always - 34206 ... 195 Hardware_ECC_Recovered 0x001a 100 100 000 Old_age Always - 27170949 That's 27+ million such recoveries during the, admittedly intensive, 34 hours of PreClear. On it's own, that seems excessive. But, relative to ~9k during the previous 34000 hours, it seems obscene. I'd focus my attentions/suspicions in this direction. Do you have the pre- & post- SMARTs for one of the other (non-lethargic) HD753LJ drives to compare those values? --UhClem
