I just put a Western Digital Caviar Green (WD30EZRX) 3TB SATA3 6Gb/s 64MB (OEM) hard drive into a LaCie d2 Quadra eSATA 3Gb/s | USB 2.0 | FireWire 400 & 800 housing that used to have a 1.5TB Seagate HD in it.

The problem is that the Mac is only seeing a 801.23GB disc with 800.59 free.

Was there something that I should done during the swap? Or am I out of luck and will have to purchase a compatible housing for the WD?

The Seagate HD was starting to have I/0 errors.

This was the second Lacie (Seagate HD) to die in the last four months.

No more Lacie for me.

With Lacie I would tend to question whether the issue was with the Housing, Power Supply, HD, or was a combination whammy. Reliability and Lacie have not been synonymous over the past few years.

Your D2 is not compatible with drives larger than 3TB
The firmware cannot handle the advanced formatting with large blocks.
The MacAlly G-S350 series enclosures we have tested to be compatible with 3 and 4 TB drives

I take it that since I require Firewire 800, this model enclosure would be the correct one for the 3TB WD?

Not doubting CanadaRAM's excellent knowledge and advice, and I'm sure not a fan nor an advocate of any Lacie drives, but their LaCie d2 Quadra Hard Disk eSATA 3Gb/s | USB 2.0 | FireWire 400 & 800 model seems to have a 3TB option, or are they using different firmware or some different bridge circuitry within the 3TB LaCie model?

What I also got to thinking. This is my model.

LaCie d2 Quadra Hard Disk eSATA 3Gb/s | USB 2.0 | FireWire 400 & 800 500GB, 1TB, 1.5TB, 750GB, 2TB, 3 TB, 1TB 5400rpm, 2TB 5400rpm, 3TB v2b.

I'll throw the WD into a dock later and see if the Mac sees 3TB.

CanadaRAM

The models they ship now with 3 TB drives may well have different firmware or SATA / FW controllers than the older D2 models.

Based on the symptoms (800 GB instead of 3 TB) the individual enclosure being used is not compatible.

You can contact LaCie to see if there is a possibility of a firmware upgrade that would fix it. Not possible though if the incompatibility is in the hardware controller.

The MacAlly FW800 enclosure we have tested with 3 TB drives, yes.

So it likely the Mac only sees 800GB instead of 3TB, even though the enclosure previously held a 1.5TB HD, all because of firmware?

Before giving up hope have you erased and repartitioned the drive in Disk Utility? I haven't seen your issue on a large drive but I've come across it a lot with small thumb drives.

Okay.

I just started writing zeros to it with Disk Utility.

Two hours to go.

Oops!

Now three hours.
