    This doesn't sound good at all.

    I installed Drive Bender yesterday and was very pleased with the ease of install and the increase in write speeds.

    John: Do you run it on Windows 8?

    Hi pcdoc.
    I was having a similar problem with a HighPoint card, a PCI-X RocketRAID 2220. It would work for weeks, then the alarm would go off. I could not identify the drive that was apparently at fault, nor did any of the SMART information or Win7x64Ult Event Viewer. As it was my main data storage area, consisting of 8x2TB Samsung HD203WI drives.
    I eventually got really worried, and bought a Synology DS2411+, and set that up with those drives and four others in a Hybrid RAID Array with 2xHDD fail-over.
    Many weeks went by… I then retired the HighPoint 2220 as it looked like that was the cause of my woes.
    Then… Occasionally, one particular HD203WI, would drop out of the RAID. I took it out. Ran a quick SMART test – passed. Ran a full SMART test – passed again. Did a surface scan – passed with flying colours.
    Put it back in the Syno box. Quick and Full SMART tests – passed.
    Shrugged, and set to repairing the array. This took a couple of days. No problems.
    More weeks went by…
    The drive drops out again. More tests – passed.
    Swapped the drive to a different slot. Ran tests – all passed.
    More weeks…
    Drive drops out again.
    1. I write too much.
    2. The drive is poorly.
    3. I can't return the drive as broken, because it passes all tests, every time!
    4. Bought another drive, and used the dodgy one as a "backup" for non-critical files.
    5. HighPoint 2220 back in action. for about two months – no problems.
    6. You may have an intermittent drive failure that only management software/managed hardware can track.

    I wonder whether this might be an issue with using/not drives not intended for RAID. There could be TLER (time limited error recovery) settings that are too long for raid and too much delay can cause them to drop out of the array.

    On the flip side, using RAID drives in a desktop (or Gasp! A/V (DVR/Tivo) drives TLER=0 where pretty close is good enough) might give up too soon and assume the RAID controller will correct it.

    Bottom line? There's a difference in the firmware settings between different classes of drive that make them suitable or unsuitable for reliable use in different hardware / software environments.. So, your drives may be perfectly fine but have firmware settings that aren't suitable for the hardware/software using them.

    You aren't alone. This describes my long bout of testing with Storage Spaces.
