I have a test server that runs Windows XP, and we attach an external hard drive to it via USB 2.0. (And yes the computer has USB 2.0 ports on it)
The drive is a 1.5 Terrabyte Segate FreeAgent drive (model ST315005FDA2E1-RK) which is formatted with NTFS. It is
hooked into a Belkin Hi-speed USB 2.0 7 port hub (model #F5U307).
If I leave the external hard drive connected to it for too long I get a message that says something about "Windows Delayed Write Failure" and then the external HDD re-attaches itself to the server, but it always crashes any programs that happened to be using the drive at the time as well.
Is there any solution to this problem, it's plauged me for years!
P.S. Yeah, I know I should probably upgrade already. I'm waiting for Windows 7.
(Oh, and after taking a look at the specs on the FreeAgent website, apparently after 15-minutes of non-usage this thing turns off! It says however that you can adjust this setting...)
Just as an update to this question, since I tried changing the power save settings to off, I've left the drive and a virtual machine I had running on all day and thus far have not received the "Windows Delayed Write Failure" error that I had received before. If anything changes I will update the post.
