I have a Maxtor 3000LS 40GB external hard drive that is no longer being recognized by Windows XP. The problem started after I installed the XP SP2 onto my Sony PC.
Initially, I received "Semaphore Time-Out" errors. I could, at that point, unplug the drive from one USB port and plug it into another...and the OS would then recognize the external drive. That worked until I exhausted all the USB ports - and now the OS will no longer recognize the drive, at all. Albeit, the Semaphore Time-Out errors quit on their own.
I have tested and replaced all cables. I have taken off all other USB devices, external devices, and USB Hubs. That makes no difference.
I have searched for new drivers for the Maxtor 3000LS, no luck there.
The drive shows under the icon to "safely remove hardware." However, the drive will not show when I go to My Computer -> Manage -> Disk Management.
I can plug other USB devices into any of the USB ports on the Sony PC...and all works well. Just the Maxtor is no no longer "fully" recognized on this machine post XP SP2, on any port.
I have plugged the Maxtor drive into my ThinkPad, and it works just fine and is recognized: No errors.
Net: The Sony PC will no longer assign a directory letter to the Maxtor 3000LS, and the 3000LS 40GB external hard drive remains no longer "fully" recognized by Windows XP on this PC. The drive shows under the icon to "safely remove hardware." However, the drive will not show when I go to My Computer -> Manage -> Disk Management.
Clearly - this is the fallout of installing XP SP2. I just can't figure out what, exactly, to do to solve it.
