And even then only on native (in case) sas or sata, not really via usb.

Using a 3TB or bigger external disk via usb on W7 is asking for trouble and data loss. Yes, you can connect, you can even read, but you loose the moment you write.

I hope/pray that is an exaggeration.

I have a w7 box that had 4 3TB usb drives and a 4TB usb drive connected for the last week. Quite a bit of writing going on (several TB worth). I have not noticed any corruption. I really care about most of that data.

I have the md5 hash calculated and preserved for most of that data while the drives were connected to Linux. I may need to run a bunch verifies and see if I've destroyed anything.

I truly hope not, but thanks for the heads up.

Well, AFAIK, whether or not data-corruption occurs is mostly a matter of the Mainboard (Hardware), UEFI (BIOS does NOT work), and Drivers.

If your MB has a UEFI, and you boot with it, you can try, with BIOS forget it, at least under Windows 7.

With boards and firmware that is certified for W8 it works as long you boot in UEFI mode, so ca. second half 2012 and newer are OK.

An other key-point is USB3. Native (chipset) USB3 works much more often than those on PCIe-cards or extra-chips (e.g. Renesas) onboard. Intel Series 7-Chipset(Panther Point) or newer, AMD Hudson M3/A68M/A70M see: http://en.wikipedia.org/wiki/List_of_AMD_chipsets http://en.wikipedia.org/wiki/List_of_Intel_chipsets

Frustrating? Oh, yes! And: Exceptions are the Rule. Murphy LOVES you. Since this is Windows related, I'm taking it to a different list to ask questions. You have got me fairly concerned that I have corrupted a bunch of data.

Fortunately any large original data I create is written via openSUSE, but I do perform smaller steps with Windows 7, so I could have corrupted a lot of data in the last week. :(

Thanks for the very important heads up, Greg

I dual-boot with Windows 7 (ie, openSUSE 13.1/13.2/TW and Windows 7). The mobo has UEFI - but I have disabled it. The BIOS is set to boot in legacy mode. The HDDs which I use are 1TB and 2TB in size (they are all sitting in mobile racks so switch between 1TB and 2TB depending on which set of OSs I want to run). All the HDDs are formatted in ext4 for Linux (openSUSE) and in ntfs for Windows. I have no hassles of any kind with this setup. But I guess I would need to start using GPT formatted HDDs if I start using bigger HDDs to what I have now.
