USB 2.0 Hard drive - Lost Connections
Posted on 2006-04-28
I have a MHV2080AT 2.5" notebook drive in a Bytecc 2.5" HDD USB 2.0 Mobile External Enclosure. I have several of these units installed as backup drives at several different clinet locations. I have logged several instances of these drives becoming invisible to Windows XP. At first I thought that there was marginal USB poret power, but that is clearly not the case since I have observed this "disappearnce" on drives running off of a powered USB 2.0 hub as well. They are running on 3 and 6 ft USB 2.0 cables.
1) What is cuasing this?
2) How do I prevent this from happening?
Since I rely on thes drives for data backup - it is very undesireable for these drives to disappear as this causes the backups to fail.
I am running these drives on Dell Optiplex and Precision Workstations.
Thanks for any information which can help me get to the root of this mysterious phenomenon.
