In every file of harddrive specs I have ever seen there has been an
entry for Reduced Write Current and Write Pre-Compensation. I was jawing
with a bud tonight & I realized, I didn't have a clue what they were!
Usually the entry will looks something like this:
|
| Abbreviations: HDS - Heads
| CYL - Cylinders (Tracks)
| RWC - Reduced Current Write Compensation
| (0 indicates RWC on all the time)
| WP - Write Pre-Compensation
| (Usually 0 or number of CYL's)
|
| +--------+------------+-------+-------+-------+------+--------------+
| : ATASI : MODEL : HDS : CYL : RWC : WPC : NOTES :
| +--------+------------+-------+-------+-------+------+--------------+
| : AT3020 : 3 : 635 : 0 : 0 : :
| +------------+-------+-------+-------+------+ :

Do you know what RWC & WPC are?

PS.
Any pointers to literature would be appreciated. Who has written a good
book on the nitty gritty of hard drives?
