Frequently Asked Questions Q: Does it support 5 SATA port multiplier with JMB321, which is very popular on the net? Thank you. 1 answers A: Yes, It does, the chipset we used is JMicron Q: Are you working on firmware to support silicon image? I would love to be able to use your product! 1 answers A: Unfortunately, Silicon Image is longer exist, therefore we can not get any data, or support to make this compatible with our adapter. Sorry there is no other way Q: Connecting Ratoc SA-DK5ES multi HD tower with Mac Book Pro 15" 2016 with High Sierra OS. Ratoc Support wrote: SA-DK5ES must be connected to the eSata host adapter that supports Port Multiplier. 1 answers A: Ratoc SA-DK5ES is an old SATA II ( 3.0 Gbps、1.5 Gbps) box which is most likely using Silicon Image. Our eS3U31 does not support this chipset Q: I also bought the eS3U31 via Amazon. I have four Sil3726-based PM enclosures. The Sil3726 IS on the list of supported PMs on the product page. The eS3U31 does not negotiate a link with any drives in the enclosure. The light for drive 1 flashes several times 1 answers A: Sorry for the mistake on our website. This new adapter ONLY supports JMicron chipset. Web page already corrected Q: How can one flash a defective unit when you only have a Mac to flash it with and a JBOD? 1 answers A: To flash you must use Windows Q: I bought the eS3U31 product from Amazon. My drive is not being detected. I'm using a Sonnet Fusion D500p enclosure with 5x WD2002FYPS 2 TB drives. I tried restarting my laptop and made sure all drives seated properly, but that didn't seem to work. 1 answers A: Currently, our adapter only supports JMicron chipset Q: Trying to hook this up to a Sans Digital TR5M+bnc w/ 2 WD Red Pro drives and a Mac Mini [Loaded] - no luck. Also on PC or MacBook Pro - no luck... Does latest USB just not load or is unit pooched/DOA? Not shown in USB panels as a device or anything... A: Til now our adapter only supports PM mode with JMicron chipset
