Booting to Safe Mode and renaming _that_ file on the usb hdd won't solve the issue. It may take one or two times to redetect the hdd after a rename but XP will make a new System Volume Info folder on it. And probably keeps writing to it to deny "safe removal". Perhaps there's a "bootable" flag being detected in the usb hdds MBR?

Sano- thread found thru tomshardware- I have a 60GB pata FAT32 ext usb hdd, formerly on a w98SE machine as a data hdd. It has 6 partitions, one of which is marked "Active" in XP Pro Disk Management. (the first position on the disk). I've used it on and off for several months. I don't recall if it has always thrown the 'The device 'Generic volume' cannot be stopped because a program is still accessing it.' message. But it has the last two days I've used it. I plugged it in and opened XPs Disk Management> opened properties for the active partition> which opened a window with -all- disk devices listed. Floppy, boot drive, USB hdd, and two optical drives. Selected the USB hdd and ticked Properties. Policies are set to optomize for Quick Removal. Ticked the Volumes tab and the hdd is set with a MBR. I ticked Populate and all the partitions appeared. I ticked the active one and then ticked the Properties button. In the resulting box, I was presented with an option to remove all backups except the last (I assume Good) one... "to save space". I ticked that option. My P4 2.8Ghz hummed for maybe a minute removing backups. I didn't consider the "where" of those backups. Maybe 'every' extra backup on the entire machine or perhaps a backup, hidden, and written to the 60GB hdd, (the ext usb hdd). After closing out of all that and closing Windows Explorer.... removing the hdd is _not_ a problem.
From: mike loeven on 15 May 2010 14:25 i think i found a fix for this as well as the fix for phantom drive accesses. in the disk properties there is a check box that says allow indexing service to index this disk for fast file searching. if you uncheck this and select all folders and subfolders. it does fix the problem for me. but if you havent done this try disabling the indexing service and trying to eject the drive again i have a feeling that is whats locking it down. if you have an active virus scanner you can try adding the drive to the exclude list or disabling the scanner just before ejecting. alot of services can access the disk without you knowing that they are even there "Sano" wrote: > Sano <gregs.poopysuper(a)gmail.com> wrote in > news:Xns9D6E5478495F8poopy(a)216.168.3.70: > > > =?Utf-8?B?dmljdG9yZDY2?= <victord66(a)discussions.microsoft.com> wrote > > in news:E238E9DA-C7AC-4B10-961B-FDDFABC48B2C(a)microsoft.com: > > > >> When I try to safely remove my Maxtor usb drive I get an error > >> message: 'The device 'Generic volume' cannot be stopped because a > >> program is still accessing it.'
