Strange USB flash drive problem

[Hell-fire]

Hi,

Just recently, I've been having a problem with USB flash drives. At work,
we use Windows XP Pro on IBM notebooks. On the English version, I can write
to the USB flash drive, but on the Japanese version, I can read, but not
write. I have tried this USB drive on other computers at home, with English
and Japanese XP systems and they work. This is not isolated to my notebook
with Japanese OS, other ones I tried also can read, but not write. The
English OS ones have no problem. Untill a week ago, we didn't have any
problems using this USB flash drive on the IBM Japanese OS notebooks. Thank
you

I would put a flash drive in one of the problem machines, and open Disk
Management. Rightclicking the drive and changing the drive letter may toggle
the file system.

Hi Mark,

Thank you for your suggestion, unfortunately, it didn't work. The problem
seems isolated to IBM notebooks with Japanese XP Pro, the IBM notebooks with
English XP and non-IBM notebooks and desktops with Japanese XP doesn't have
any problems.

Only thing that was done on the notebooks, was some windows updates. I
heard that somewhere in either the system settings or registry, there is
something that might have been tripped, to have USB flash drives read only,
but not write.

Locate and click the following registry key:
HKEY_CURRENT_USER\Software\Microsoft\Protected Storage System Provider On
the Edit menu, click Permissions . Click the registry key for the user that
is currently logged on and ensure that Read and Full Control are both set to
Allow . Click the Advanced button, ensure that the user that is currently
logged on is selected, that Full Control is listed in the Permissions
column, and that This Key and Subkeys is listed in the Apply to column.
Click to select the Replace permission entries on all child objects with
entries shown here that apply to child objects check box. Click Apply , and
then click Yes when you receive a prompt to continue. Click OK , and then
click OK again

Hi Mark,

Thanks again for the suggestion, but no luck with that. Everything for
Admin and my user ID had full permissions. Just wierd that its only the
Japanese IBM notebooks and nothing else.

USB drive can be write protected by a registry value:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies

The value WriteProtect should not exist or at 0.
