Warning: the dma on your hard drive is turned off

Probably I will ask a friend of mine to solve this.

As I remember, most of HD with this legend "master=on, slave=off", means that you can remove the jumper for a slave disk.

I saw on Seagate, and Samsung Disks

Excellent point -- I missed the obvious there, but believe that to be correct, and also valid on Maxtor HDDs I have used in the past.

Hi,

The IDE drive jumpers will depend on drive manufacture. Most set the Master/Single with no jumper. Then for multiple drives you would select a Master/Slave with a jumper setting. You should google for the drive manufacture & model to get the jumper table settings. If you use the 'cs' then the position on the cable will decide device assignment. Some manufactures provide a jumper table physically on the drive. You might find a mask labeling on the PCB of the drive.

OP, you seemed to have a contention problem. The device jumpers were not set properly, if you want a Master/Slave then set the jumpers properly. Place the Master at the end of the cable.

If the drive is a current IDE then be sure to use a '80 conductor' cable, place the index (red/blue stripe) pointing to the power supply connector, most new drives have a key on the connector to prevent the connector from being placed incorrectly.

A lot of drives will default to slave if the master jumper is not set. Many drives do not include a jumper to set for slave - they assume if master is off, slave is on, with CS being the exception to the rule.

Thank you for the advice. I found these:

instructions for the jumper settings and just removed the jumper from the slave drive (which is SEAGATE,ST3160812A).

Actually the drives' jumpers were set properly previously. In fact the only change I made was to put the drives at their correct places on the 80-conductor cable. So far after several reboots things seem to be ok. Time will show.

Thank all of you for your responsiveness and collaboration.
