Delayed write failure

I bought two brand new drive, one Seagate and one Samsung with Vantec external enclosure.

I received a delayed write failure error messages while copying data from the internal Seagate(300 GB) hard drive to a external Samsung (300 GB) drive connected to a USB hub. The delayed write failure messages kept coming and the transfer slowed to a halt.

Is there a problem with the drive or USB?
 
I have a similar problem with a 300GB Seagate in an external no-name USB enclosure.

There's a whole mass of information on the web about fixing these errors, but none of it seems to help. I'm starting to wonder if it could be a faulty drive and/or enclosure.
 
Oddly enough, I've had this occur in every external that I own but my prebuilt external Western Digital MyBook. My Vantec NexStar 3 + 250GB Maxtor MaxLine III has been pretty good lately though. Only my 200GB WD SATA + no-name SATA enclosure ever have delayed write failures (and not during transfers), but not that often. I just turn the drive off and typically leave it off.

I'm still not entirely sure what causes the issue. I do know that I don't use write caching on my disks though.
 
This is common with external drives until you disable write caching in properties/policies. Set externals to opimize quick removal - not performance.

That was the first of many things I tried, all to no avail.

Anyone have better luck moving from usb to fw?

 
I see some enclosures are marked as "supports hard disks of up to 250GB capacity". Since when has 250GB been a line? I though the last was was 147, or thereabouts? Surely if a controller can support greater than that it can support at least up to the next line?

Anyone know what the story is here?

Strange. I use a regular SATA external enclosure and with several SATA drives and I've never had any delayed write failures, not even with my PATA external enclosures. I've put in many drives in fact every single manufacture like Maxtor, Seagate, Samsung, WD, etc. has been in my enclosures and not once have I had a delay write failure UNLESS it was due to a failing hard drive.

Most of the enclosures I've seen have mentioned that it supports up to 500-750GB drives.

Assume you can find Device Manager (Control Panel, System, Hardware, Device Manager.) The highlight the external drive, and click on it. Select Properties, and if it is removable, Policies is the 2nd tab. There are two check boxes. Quick Removal and Performance. Select Quick Removal.

If an external SATA drive isconnected to an internal SATA Port, that will be grayed out because it is electronically an internal drive located outside the main case.

I wouldn't doubt that my WD 200GB SATA drive may be going. If I recall, I believe that drive had issues while it was physically in the system that were only noticeable in the Event Viewer, but nothing physical. My PATA drive only ever did it once I believe. After I removed the casing from the external enclosure (Vantec NexStar 3), it hasn't messed up since.
 
Most USB and FW external drives will have write caching/delayed write disabled automatically - at least the ones I've had did. Even the el cheapo I rigged up from a mobile rack and a IDE to USB adapter cable (Totalled under $75 drive and all).
