Communication Error - more testing
Since upgrading to V0.7.8 I have been getting Communications errors at the end of the device read in process. This happens 3 out of 4 times - ie for all practical purposes, ALL the time (because it takes 15 minutes for each attempt, I usually give up after 45 minutes!).
This is running on Vista 64. On this very same machine, I am also running VMWare images, into one of which (Windows 7) I have installed Calibre. To be clear - this means it is using the same hardware exactly. I started off with 0.6.55 and worked my way up 0.6.55 - worked perfectly 0.7.1 - seemed to work, but way too slow. Took 27min for only 33%. Gave up. 0.7.2 - worked fine, but did not see the SDHC card on the reader. 0.7.3 - worked fine. No errors. 0.7.4 - works. Some other errors though 0.7.5 - works. Other errors and crashes often though 0.7.6 - works. So far seems to be the best version. No crashes yet. So it would look like 0.7.8 has introduced some bug.

As I said before, 0.7.x does a lot more when interfacing with devices. This is probably triggering an underlying hardware fault in your reader. Either get a new reader or stick with 0.6.x

Well, 0.7.3, 0.7.4, 0.7.5 and 0.7.6 work just fine. So it is NOT a simple 0.6 vs 0.7 problem. Mind you, it could still be my Vista 64. The versions that work are in Win 7 (32).
It seems to be the 32 gig SDHC that seems to be triggering the problem. At least, that is where the error seems to occur. I might switch the SDHC next. |

Most devices have problems with cards larger than 8GB, though I have no personal experience with the PB.
