SIIG vs. Western Digital

A few years ago, I purchased a Cool Dual SATA to USB 2.0 Docking (Part #: SC-SA0412-S1) manufactured by SIIG Inc.

The product has worked wonderfully and has made my life so much easier. The cheap price vs high quality is so skewed!

However, a week ago I purchased a 2.5 TB WD Caviar Green SATA Hard Drive (Model number: WD25EZRSDTL). I know my Win XP machine won't read the whole 2.5 TB. However, when I tried to use it on my Win 7 machine it showed up as a 320 GB HDD!

I called Western Digital and they said

some older disk enclosures, if the HDD being read is larger than 2.0 TB, act as though the first 2.0 TB are an error and ignore them. It then begins counting over at the 2.0 TB mark. The difference is then passed out of the enclosure, back to the computer, as the "true" capacity of the drive. Western Digital said to contact the manufacturer of the enclosure and ask them for a firm ware update that would accept drives larger than 2.0 TB and not assume there is something wrong and truncate the first two terabytes.

In my case, the difference of my 2.5 TB HDD was 320 GB. So, my copy of Microsoft Windows 7 was displaying that my hard drive was only 320 GB!

I contacted SIIGn and they replied quickly saying:

I will ask the engineers if a firmware update is available that addresses this issue. It will take a few days to get the answer. I will contact you in a few days.

a few days later I get:

Hello,Unfortunately, we do not have the update firmware for this docking at this time.Please check back with us from time to time.Trung Pham
