Over the past two months I’ve been pursuing a problem w/ASUS…
BEWARE: if you get a case that has an eSATA front port and you connect it to an internal motherboard [Intel H55 and maybe others] SATA port, it cannot be configured to have an eSATA hard drive ‘safely removed’. You will have to turn off caching (slow) or risk data corruption when removing it.
ASUS customer service is terrible and it will further adversely affect their bottom line because they are ruining their reputation. …So much for their “goal of 100% customer satisfaction”.
They ½-answer submitted technical inquiries to show they care, even though it is obvious they do not want to get to the root of or appropriately solve a problem system builders may be encountering and finding annoying. They do not seem to know Windows very well nor comprehend the underlying problem, nor do they spend any measurable time even reading the history of the problem, trying to determine where the problem really lies. They defer simple system builders to Microsoft $upport when it is clearly not a Microsoft problem. Concurrently they defer to Intel support (the maker of the chip/driver likely causing this problem and a company not selling chips to/supporting end-users) – when ASUS should be contacting Intel themselves, as an integration partner, to resolve issues such as this.
