UASP capability of optical drives

Post by martini2 » Fri May 17, 2019 8:00 pm

Hi,

i have a ASUS BW-16D1HT and a LG BH16NS55 which i sometime use with a sata/ide<>usb2 adapter as external drives in windows 10. It works with makemkv without problems but is very slow due to usb2 speed.
Recently i bought a cheap sata<>usb3 adapter with a power supply (~20Euros) in hope to rip the disks with max speed but none of the drives is recognized by windows. A brief moment after pluging the adpter into the pc a yellow triangle with a exclamation mark appears on the adapter icon. In the adapter settings i see errors like "could not start the device" or "could not assign address ..."
The description of the adapter claims the drives must be uasp enabled. Is this the case for the mentioned drives? I can not find any info on this. If no, can this be fixed in the firmware? (The asus runs mk3.10 and the lg original 1.02 firmware)
Maybe the adapter ist defective? Can someone recomend a good and not too expansive sata<>usb3 adapter that work with this drives?

Seems to be a lot of info available... some reading required:

i wouldn't worry about uasp support just get a usb 3.0 adapter that works with optical drives that fully support atapi. optical drives are only sata 1.5 gbps or 150MB per second anyway and you are never going to exceed 50 MB per second read thats only 10% of the usb 3.0 standard of 500MB per second. and UASP still wont help an optical drive because that is for reading and writing many small files at once movie files are one big file you will see no improvement.

here are some usb to stata adapters/enclosures that work with optical drives.

thank you for the links, unfortuately the link to the search results did not provide any information about the uasp compatibility of the mentiond drives and
the enclosures are, if avaiable, too expansive in germany. They cost twice as much as in the US so getting a new drive is much cheaper. The LG is ~ 60Euros.

I solved the problem buying a "Sitecom USB 3.0 to SATA adapter incl. Power Adapter" from a local store (MediaMarkt) for about 35Euros. It works out of the box in Windows 7 and Windows 10. The drawback ist the price and a very very short usb cable (~10cm).
The read speed with the asus BW-16D1HT is ~30Mb/s for a UHD so i think it is working ok.

The cheap CSL-USB to Sata adapter from Amazon seams to be broken o just incompatible.

I had the same issue. I did this:

The UASP is implemented in the driver uaspstor.sys. To disable loading of this driver, run regedit, and set the start value to 4 (disabled) under: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UASPSto‌​r

and rebooted. It then worked and interestingly when I set the key back to it's original value it still worked!

Cheers
