One of the servers DMA is disabled from time to time, - at least it shows that under status in WHM:

Disk hda7 (/) DMA+ 66 %
Disk hda1 (/boot) DMA+ 19 %
Disk hda8 (/home) DMA+ 52 %
Disk hda5 (/tmp) DMA+ 4 %
Disk hda2 (/usr) DMA+ 66 %
Disk hda3 (/var) DMA+ 44 %
Disk hdb1 (/drive2) DMA+

When I choose 'Optimize EIDE Harddrives' in WHM it returns back to normal as above, but then DMA is disabled again and I have to optimize it again. Is this hard drive about to crash or why is this happening?

Thanks

The IDE cable might be bad. Make sure you're using an 80-wire one instead of a 40-wire. (I've made this mistake before, and I felt pretty stupid when I noticed it.) :)

Thanks, it should not happen. The NOC will keep an eye on it should it happen again.

Only ATA66/100 needs 80 wires
UDMA33 doesn't :D (I hope you don't have such old drives eh :P)

My old Fireball KA didn't had DMA for months until the day i noticed a pin was broken, removed the PCB and resoldered, works fine :D

you solder your cable??? :eek: Why don't just get a new one.?
Or it's your hdd?

Given 'pin' and 'PCB', I would assume the hard drive circuit board. That, or the motherboard...
