What would cause an internal HD to simply disappear in Windows?
in [Storage]

From: Yousuf Khan on 21 Mar 2010 11:16 Something strange just happened recently, under Windows 7, although I have seen it happen under Windows XP before too. A hard drive that's internal (i.e. always there, not physically removable), just disappeared from Windows sight. No longer accessible, HD Sentinel didn't see it either. Rebooted, and everything was fine, it came back. But there were no warnings in SMART about that drive. Is there something in the Windows logs that I can see about this? Yousuf Khan

It looks like I was experiencing simultaneous problems with a SATA hard disk and an IDE DVD drive (although that's weird since there was nothing inside the DVD drive at the time). I saw the following messages: Disk Error message: > Log Name: System > Source: Disk > Date: 21/03/2010 7:31:57 AM > Event ID: 15 > Task Category: None > Level: Error > Keywords: Classic > User: N/A > Computer: desktop-yjk_w7 > Description: > The device, \Device\Harddisk1\DR1, is not ready for access yet.

Normally you have to be quite a while between reboots to see that, or be running something that produces memory leaks very badly. > But there were no warnings in SMART about that drive. Because it was nothing to do with the drive, just the OS. > Is there something in the Windows logs that I can see about this? Yes, you should be able to see evidence of memory leaks in there when the lack of free memory becomes quite severe.

It may have been a glitch with your IDE/SATA converter.

Well, I do tend to run this system like a server. It's usually up for weeks at a time, 24 hours/day. The main app that runs on it during this time is a bittorrent client. >> But there were no warnings in SMART about that drive. > > Because it was nothing to do with the drive, just the OS. I'd have thought at least some kind of CRC error increment or something. Yousuf Khan |
