Posted by Dimitry from Moscow on May 30th, 2008


Laptop Compaq nc6220, 512MB mem., 60GB hdd NTFS formatted, Windows XP SP3
I'm tired looking for solution... please help me somebody!
When I copy any file from hdd to usb, network or to the same hdd another
folder the transfer rate is about 200kbp/s!!! For 100MB file it takes hours.
But write operation is ok - about 15-20 Mbp/s.
So first I replaced hdd with a new one - no help.
Then I deleted IDE controller from Device Manager and reboot twice - no help.
I stopped unnecessary services and unload antivirus - no help.
I setup 3rd party cache manager software - no help.
I reinstalled Windows from scratch. Problem disappeared and...... appeared
again after two weeks!

HELP ME!

Using FileMon I have found that file reads by portions of 65535 bytes.
On my desktop this value is 160 times bigger - 10485760
How to fix it?
