Dear, Sirs!
I have the problem with External Case for 3.5" hard disks using USB 2.0
(model Chronos HD-337-U2). I have no USB 2.0 in my laptop only USB, so I had
to buy PCMCI - USB 2.0 card model: UB 200 from ARGOCY (www.arcocy.nl).
PCMCI drivers were installed by me as described in users manual, i.e. after
installation I had upgraded drivers for USB 2.0 Root Hub device & Card Bus
to USB 2.0 Enhanced Host Controller. When I was using External Case via USB
1.1 hard drive was visible and I could read & write any files on it, after
installation PCMCI - USB 2.0 card and after connection External Case via USB
2.0 I hade encontered the problem my PC asking the hard (red LED is lighting
on the External Case), but then some frizing with RED LED and External
Storage divice disapeared from dialog box for safety removing any external
divices, and from "My computer". After restarting the computer files or
folders wich were tried to be accessed lost. After some such actions after
rebooting I found that all my external hard (120 Gb) was not formated and
all info was lost. Please help me to dicide my problem. Thanks in advance!
