I'm encountering a huge problem with my HP ProBook 4720s notebook.
I'm trying to use an external drive through eSATA port. When I connect it, Windows often freezes/crashes and numerous 'iaStor' Evetn ID 5 errors appear in the System event log - "A parity error was detected on \Device\Ide\iaStor0":
The drive also disconnects itself randomly.
This problem is known for almost 5 years now (started in Vista systems):
Some solutions over the internet suggest to turn off write caching for the hard drive. However this degrades drive's performance significantly. Some say also that this problem is Windows 7 64 bit specific.
I've updated Intel® Rapid Storage Technology to the latest version, however with no luck.
My external drive is Western Digital Caviar Black 1.5TB (model WD1502FAEX) and it is connected via Welland ME-601J docking station using eSATA cable. This drive works fine with another USB 2.0 only Welland enclosure.
Can you please help me in solving this issue?
I've testes two Welland eSATA hdd external enclosures (model ME-580J and ME-601J) with three different hard drives - Seagate, Samsung and Western Digital.
Only Western Digital threw errors or wasn't recognized at all in RAID enclosure (ME-580J). I'm returning that hard drive probably if there won't be any solution in the next couple of days.
