I have recently upgraded from XP to Win 7.I have 2 disks in my PC which allows me to transfer data rom the operating system Disk which is SATA to the Backup Disk which is IDE.I tried to do this with 130 Gb of data and it gave me a transfer time of 12 hours!.It therefore displayed a transfer time of 3 mB/sec.I googled the transfer rate of IDE as it will be the slowest rate and i think i should be expecting around 40 mB/sec.Why is it so slow?
