I apologise if this was posted more than once, for some reason the
emails i sent were not reflected back to me, so i assumed they had not
gone through , i checked the archive on the web page and they were there.
For some reason some messages are not coming through on my gmail account.

I have a USB hard drive. Whenever I open two programs which utilise

attempt to write to the hard drive lock up due to what i suspect must
be some issue with the USB driver and perhaps a deadlock involving
multiple concurrent accesses to the drive. When they attempt to access
the drive the programs can lock up for several minutes before being
unblocked. When only one program is using the drive this behaviour
does not seem to occur.
It seems most likely that this is a USB level problem involving the
USB drivers. I am using FreeBSD 7.1. It is annoying behaviour to say
the least and I wonder what can be done about it, and if this issue is
being addressed, perhaps in the recent redesign of the USB code. It
seems to be a pretty consistent issue, happening with multiple
installs of FreeBSD and different drives.
