prolific 250GB external disk

[M. van Nieuwenhoven]

dear users

I bought a Prolific PL3507 Combo Device (1394-ATAPI rev1.10) 250 Gb external
harddisk. Unfortunately the disk is not recognized by my computer (Dell
Dimension 4600 with Windows XP SP2 and two internal harddisks). Neither the
FireWire connection, nor the USB connection is recognized. The disk is,
however, recognized by my laptop with Win XP professional, but I want to use
it for my desktop computer.

Please help me to solve this problem asap.

Thank you in advance,

You might go into the control panel and try to install and let Windows
find the correct drivers. Also, check Dell to see if there is a issue
with their computer and USB devices. Sometimes there are Bios revisions
that correct such problems. Make sure you have the power to the drive.


Also, do a Google search for Prolific PL3507. You will find many users
have found this chipset has large file corruption problems. The
firmware to correct may or may not be updated depending on the chipset
revision. I found mine worthless for backups and the firmware could not
be updated, so I ended up with a Western Digital external. No more
corrupt backup files.
