I have a Win XP pro PC and a Win 7 Pro PC.
Sometimes when using my SanDisk Ultra USB3 128G flash drive it says it
is write protected.
I do not do this !
Why and how does this happen ?
I cannot figure out how to un-writeprotect it in the Win XP pro PC.
THERE IS NOT MECHANICAL SWITCH on the flash!
But if I put it in the Win 7 Pro PC and do a quick TOOLS/ERROR-CHECKING
check it will take the write protect off and I can then again use it in
Win XP Pro.
How do I do this in Win XP Pro without have to lug my Win 7 Pro desktop
around with me when I travel ?
I have other flash drives and this never happens on them.
They say to test the stick on another computer, to tell if
it's a drive issue or a registry issue. If the stick
remains write-protected on all computers, the stick
itself is defective.
Otherwise, hunt down a registry recipe. Or "blame that computer".
Some flash storage devices, have features as a part of their
"standard". For example, must people neither know nor care
that SD stands for "Secure Digital" and there is a whole
feature set related to security. Such a feature can
inadvertently prevent usage of the device, even when
the user has no interest in security at all. For example,
my digital camera uses such a device, and some day, it
might just stop writing, for no good reason.
This is also why, when asking questions about devices,
you need to know what kind of storage device it is,
to recollect whether it has "security overhang" and
the potential for failures that prevent access. Take
for example, an FDE hard drive, where in the blink of
an eye, the entire drive is filled with "noise" because
the crypto polynomial was wiped.
You should never buy storage devices with security
features you don't need. Tell the manufacturers what
you want, by buying the ones without security, if
it is possible to do that. If you have a HIPAA requirement
for work, that will dictate what kind of drives (or
handling procedures) are "legal" to use for you :-)
