I have had the above drive since May 2009. For about a year it has been connected via e-SATA cable and working perfectly until this weekend, when the drive began losing its connection (disappearing from Windows Explorer, Disk Manager, etc. Unplugging the power cord and re-connecting solves the problem temporarily, but after a while the drive again disconnects.
When connected, Disk Manager says the partition is “healthy”. Disk error checking reveals no problems.
I have recently updated various drivers on my computer (running Win 7 64-bit) but none I could associate with e-SATA (except, perhps Intel SATA AHCI controller (iaStor.sys)). I rolled back to the earlier version of this driver, but this did not fix the problem.
Any suggestions, please?
