was wondering if anyone can help me with this bizarre problem I'm experiencing: I've replaced the DVD drive in my Thinkpad T400 with the Lenovo internal SATA II enclosure. In it, I placed a 500GB Western Digital Scorpio Blue (5400 RPM, SATA 3Gb/s transfer rate, 8MB buffer). I installed my OS (7 Ultimate 64bit) on my C: SSD and put all my other files on that D: drive. It has worked well for almost a year and a half and I'm actually using it now.
A couple of months ago I started experiencing the following phenomenon: I fly a lot. Once in a while, my hard disk just disappears from the OS, as if the enclosure was yanked out of the laptop. I mean, I actually don't feel it, unless I'm accessing a file or a program on D: at the time, that just quit. Many times, the file is in memory, and I only notice the disk is gone when trying to save it.
This happens only during flights (never happened to me on the ground), usually in the first hour or so (still ascending?). Once I notice the problem, all I need to do is pull out the enclosure and push it back in (can't eject it from the OS as it's no longer there).
I have no idea what's causing this - the enclosure sits well within the laptop, and as mentioned, this never happened under regular circumstances. Is this the hard drive, impacted by changes in altitude? Does the air quality impact the enclosure? Which part do I need to replace to ensure this won't happen again, the enclosure, the hard disk, or the laptop?
I wondered about it for quite some time, but this week, I actually lost an important chunk of work - so any assistance will be deeply appreciated.
