Difficult time with 4TB drives

[GeorgeHR]

My system has 2 4TB drives on a Highpoint 2300 card. They work fine.

Bought 2 more 4TB drives. Put them on my Highpoint 2604 card. They show 4TB of size. Formats ok. When I copy more than 4TB of data or run windows error checking (full scan) the drives get corrupted and I need to reformat and sometimes reinitialize. I suspect this is due to the card having a 2TB limit.

But other people seem to have no problem with this card. Anyone with experience.

I am testing (by copying files to) the drives on the 2300. It should take 4-5 hours to get to success or failure.

If the card had a 2TB limit, the 4TB drives would just show up as 2TB drives.

I would have expected that.

The drives showed up as 4TB (3.6TB).

Currently, one drive has 1.5TB free and the other 1.75TB. I am getting close to failure or success.

My testing is done. THe drives work properly on the 2300.

It appears the 2604 card does not properly support 4TB drives. It formats them to 4TB (3.6TB). But after 2TB of data is written the file/partition tables are corrupted.

If I was seeking to prove the 2604 is the problem, I would put the drives back on the 2604 and let it fail.

But I am happy. I wi;; replace the 2604 with a 2300.
