Hmm, that seems more like a caching issue. Try disabling or enabling write caching for the devices connected, from this tutorial
. Some devices hate cache or don't work well without.
If you want me to find better drivers
I need either the full card name (maybe written on the box or manual or even on the card itself) OR what is written on the biggest squared chip on the card (the name of the card's controller, which is the "brain" of the card). This
is the page on the manufacturer site. Seems like there are three different controller models, and that the chip is below an heatsink. Don't remove the heatsink if there is one.
Afaik, Etron controllers are the low-end of the bunch, prices of ebay notwithstanding. Not that it matters a lot anyway, I had to work with the cheapest un-branded ripoffs of ripoffs and once I identify the controller name and find the right driver
they work fine.
Btw, the only driver finding software worth something is DriverPack Solution
, mainly because it uses the open-source packs of drivers called DriverPacks
I used since the old XP days to make all-in-one install DVDs, others I tried tend to misfire too much.
