rsr Posted October 10, 2006 Share Posted October 10, 2006 I recently installed from scratch 10.4.6 (JaS), 10.4.7 Update (JaS) and finally 10.4.8 Update (JaS). Everything seems to work fine EXCEPT external USB storage. The disk that used to work perfectly w/ 10.4.7 is detected and I can browse folders etc. BUT after copying, say, a couple of 100 MBs worth of data from the USB disk to the computer, sometimes a Gig or two, the copy freezes. Hard removing the disk and re-plugging it shows it again, but still after a while it will freeze again. Haven't tried writing to it and better not doing it because this is my backup I tried the various Apple USB drivers available here [1] but 10.4.8 breaks thing completely and 10.4.6 and 10.4.7 show the same behaviour... Did the usual thing as repairing permissions and rebuilding extension cache, just to be sure. As I said, the very same disk worked well prior updating to 10.4.8... Any help appreciated...

errandwolfe Posted October 10, 2006 Share Posted October 10, 2006 Have never had any problems copying large files to external storage via USB (since 10.4.3 now on 10.4.8). It might help out if you posted you hardware specs. Also if the device is USB 2.0, you may want to make sure your computer does not have seperate 1.1 and 2.0 ports. If so, make sure you are in a 2.0 port.

Yes, it's a USB 2.0 device connected to a USB 2.0 port: Update: It seems to be related to the particular HD and / or casing. My iPod used as a disk just works fine on the same port. And, what's also strange, writing to the disk has not caused any issues, only reading all the data back to the internal HD freezes the drive... trying w/ Linux now...

iji oh Posted October 18, 2006 Share Posted October 18, 2006 I'm experiencing the same EXACT problem with a fresh install of 10.4.7 I have these issues with both a 1 gig USB thumbdrive, and a 10 gig USB storage unit. Oddly, I just transfered several songs to my iPod using the same USB port (a 2.0 port, by the way) Part of the solution I've found: I bought a used "Apple Pro Keyboard", which has two (low) powered USB ports. The thumbdrive works perfectly (but only at USB 1.1 speeds) but the larger storage unit can't draw enough power from the keyboard to work... Anyway, there's clearly some problem with 1.1 versus 2.0 issue on my computer, which is a Medion M3 Composer 5200 (Pentium 4 3.2Ghz, 2 gigs RAM, ATI Radeon x300se, MSI motherboard. One interesting thing: My bios doesn't offer an option to disable legacy support. I can either choose USB 1.1 or "USB 2.0 with additional support for 1.1") I'm interested to see what people's thoughts are.

iji oh Posted October 24, 2006 Share Posted October 24, 2006 Thanks... I installed this (the non-"log" version), and still have the same issues.
