Hello,
over time I've connected several external hard drives to my PC.
Sometimes things screwd up during hardware recognition and I ended up with
some corrupt keys under HKLM\SYSTEM\CurrentControlSet\Enum\USBSTOR

Here I list only the corrupt key names, that should display "Maxtor" instead
of "Maytor" and other garbage.

Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USBSTOR\Disk&Ven_Maytor!6&Prod_M210Q0!_!_!_!_!&Rev_CAK4]
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USBSTOR\Disk&Ven_Ma|tor$6&Prod_L240T0$_$_$_$_$&Rev_FAN4]
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USBSTOR\Disk&Ven_Oa{tor#6&Prod_O230Q0!_!_!_!_!&Rev_CAK4]
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USBSTOR\Disk&Ven_Oa{tor#6&Prod_O230S0#_#_#_#_#&Rev_CAK4]
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USBSTOR\Disk&Ven_]axtr06&Prod_L200P00_0_0_0_0&Rev_BAJ4]
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USBSTOR\Disk&Ven_]aytr16&Prod_M210Q01_1_1_1_1&Rev_CAK4]

The same corrupt names also appear in keys under
HKLM\SYSTEM\CurrentControlSet\Control\DeviceClasses\{53f56307-b6bf-11d0-94f2-00a0c91efb8b}

Is it advisable/safe to delete all those keys?
Can they cause any trouble?

Thank you,
Luke

Just so long as those keys have nothing to do with hardware needed by the
system (i.e. your 'C' drive) then you should be fine with deleting them. I
use a USB cable for my cell phone to transfer information back and forth and
it was causing problems for me, so I uninstalled the registry keys from the
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\ directory. This acts in
kind of the same way as uninstalling your hardware.

After you delete these keys, after you re-connect your device it might
re-install the hardware back to this location, unless it's already installed
properly.

When working with the registry though, remember to ALWAYS back it up. This
can save a lot of headaches if something goes wrong. In Registry Editor go to
File -> Export, give your file a name, choose a save location (some place
where you'll remember where it is), choose All for the Export Range, and hit
save.
