Hi,
I have seen and heard of people cleaning heads of drives. I have a Hitachi drive where head 0 was reading some data in the beginning of imaging, but gradually read less and less. Disabled that head and read in 100% data from head 1 and 2, but now am looking to get data from head 0. Was hoping to possibly do this with the patient heads, as donors are upwards of $180 (for a 120GB drive

). Anyone care to share good techniques for cleaning heads? (Please avoid the need to sarcastically suggest "use a can of air" - I know that will only be drastic for the drive).
Regards,
Dizi
