Greetings fellow Ubuntians,
I've been experiencing a problem with a USB drive that I've never encountered before and that I can't find anywhere in any forums. My system is Xubuntu 13.04 64-bit, with / and /home on separate partitions, using either XFCE or LXDE as my desktop environment. My computer double-boots Windows 8 although I rarely use it. I have a 16GB Kingston pendrive that I use essentially for backup with Unison. It's formatted with a 512MB FAT partition and a 15GB Ext4 partition. The problem is as follows :
1/Pendrive used to be instantly recognized and mounted
2/For several days following a failed Unison sync, the drive has been taking 4-5 minutes to be recognized and mounted both with XFCE and LXDE
3/I have other similar USB drives which are instantly recognized and mounted
4/When the same drive is connected to the same machine running Windows 8 the 512MB partition shows up immediately
5/When the same drive is connected to other machines running Ubuntu 12.04 both partitions show up instantly
6/I have re-installed Ubuntu and reformatted the drive, yet the problem persists
Basically, there seems to be a communication issue between my machine and this one drive. Although this could be coincidental, the problem seems to have started after I mistakenly ran Unison with a different pendrive in the USB slot and received an error message to the effect that it couldn't find the one that Unison was looking for, which now is slow to be recognized and mounted. It seems as if somewhere in the hidden configuration files in my home folder this drive has now been identified as problematic, when in fact it works perfectly.
Has anyone ever encountered a problem like this, or can anyone suggest a fix?
