Hello! I have a SATA dvd writer (Liteon iHAS524-32) that I would like to use as an external unit by connecting it to a SATA-USB adapter. Problem is that I keep reading that such adapters may give various errors when the optical drive is trying to write. Apparently, the JMicron chips inside these adapters is to blame, but it seems that in some cases it works OK and in some other it doesn't (?!) I couldn't find out more. Also, all the adaptors about whose chip I could find something use a JMicron, all of them. The main candidates atm are (considering also the local availablilty): 1. Digitus DA 70-148-1 digitus.info/en/products/accessories/?c=1209&p=3534 . Main positive argument: I have seen one working ok with my dvd writer (wrote 2 DVDs without problems). Cons: I know it uses a JMicron chip and some users have commented it worked OK as well but others complained about optical drive problems (see user reviews on amazon.de); only HDDs are mentioned in the manual and datasheet. 2. Manhattan 179195 manhattan-products.com/en-US/products/8847-hi-speed-usb-2-0-to-sata-ide-adapter . Main positive argument: the old version that you can see in the picture on the box in the above link as well as here: conectica.ro/display/1-63-15480-Adaptoare/Adaptor_portabil_USB_2.0_-_SATA_IDE_Manhattan.html was specified to work with optical drives as well. Maybe I could still find the old version on stock, but I kind of doubt it. Also, it has lifetime warranty.The new version, however, has any mention to optical drives removed and I'm very sure this is not without a reason. I have also found this adaptor: newertech.com/products/usb2_adapt.php that uses a JMicron and still claims optical drives compatibility. I'd rather buy locally, though. What do you think? Has any of you used a SATA adapter - perhaps one of the above ones - with a SATA optical drive? What would you do in my place? Thanks a lot!
