Quest&Probs of 851@832 (CG5G) USB

What’s the max speed for this drive in USB2.0??
8x is the max speed i can go!!

Now i only use this drive for KProbe scans.
But sometimes it hangs in mid way, and I can’t kill KProbe no matter what. The only solution is unplug the drive. How can i fix this?? Has anyone else encounter the same problem??


Yes 8x is the max read speed for anything other than single layer DVD-ROM, which is 12x. Depending on your enclosure USB2.0 will go up to almost 16x. Check you burst rate using Nero CD-DVD Speed. You need 23-24MB for 16x.

I’ve had this lockup happen a couple of times but I’ve done an awful lot of scans. Find out what chipset your enclosure uses and make sure you have the latest firmware for it, if it’s flashable.

thx C0deKing…

hmmm, i don’t know exactly what chipset it’s using. But from the manual and by the Mac driver name “USBIDE_05E3_0702”, i found this on the web :-

T: Bus=01 Lev=01 Prnt=01 Port=00 Cnt=01 Dev#= 3 Spd=12 MxCh= 0
D: Ver= 1.10 Cls=00(>ifc ) Sub=00 Prot=00 MxPS= 8 #Cfgs= 1
P: Vendor=05e3 ProdID=0702 Rev= 1.13
S: Product=USB Storage Device
C:* #Ifs= 1 Cfg#= 1 Atr=80 MxPwr=500mA
I: If#= 0 Alt= 0 #EPs= 2 Cls=08(stor.) Sub=06 Prot=50 Driver=(none)
E: Ad=81(I) Atr=02(Bulk) MxPS= 64 Ivl=0ms
E: Ad=02(O) Atr=02(Bulk) MxPS= 64 Ivl=0ms

Can u tell what chipset it uses from this info??

Sorry no. You usually have to look inside the enclosure and physically see the chipset.

There’s also the [thread=119149]The big external enclosure thread[/thread] in the recording hardware forum sticky section, but with 488 posts it’s a bit mind numbing to read through. Perhaps a post in that thread asking the best way to find out what chipset it has, would be the way to go.
