USB External Disk Recognition Problem - Curious Behaviour

Posted on 2008-10-29

Has anyone encountered a situation where a perfectly working external disk stopped working on all but one single computer? Our hard disk is now accessible on one computer only. When it is connected to all the other 19 computers in the office, the message "USB device is not recognized" is displayed. Office computers are on SBS 2003 network running XP and VISTA. The only important diffrence between the computer that sees the USB disk and the others that do not, is that the one that sees has both SATA and SCSI disks installed.

Any suggestions what may be wrong will be greatly appreciated.

Do you have any kind of security enabled that might be limiting access to the USB ports?

No. As a matter of fact, some of the computers that this disk was working on have not had any software, hardware or configuration change between when they were seeing the disk and when they stopped seeing it.

I am not new to computers, am quite comfortable with handling hardware, and write short programs for the office. This is the first time I faced such a problem and am totally confused. I approached Philips for assistance and got no answer. I sent it to Philips for repairs and have not recieved it back yet. Even if it comes back repaired, this will not satisfy my curiosity.

Do you see any alerts in Device Manager, like devices that are not operating properly? Also, do you see the drive in Computer Management (look under removable Storage/Libraries) and under Disk Management.

This being an USB device, until it is recognized by the PC no alerts will be reported, other than that it is not recognized, and Disk Management service does not show it.

I have been travelling, and been unconnected for a while. Apologies for not responding earlier.

I am using it on my laptop which, when I am in the office, is logged on to a domain. But this was no different from what I was doing when the unit was working. As a matter of fact, the one computer it works on is on the same domain, too.

In the meantime, Philips returned my unit, and it is working. They did not tell me what they did, and they did not charge me. I will keep on wondering what was causing this curious behaviour.

Thanks a lot for your time in trying to help me.
