Can you please help estimate how long to scan?

I've started a remapping scan of a 160 GB WD hdd, from which files would simply disappear after installing Fedora 13.
As of this moment it found 149 <3ms sectors, 23 <50ms sectors, 30 uncorrectables and 13 AMNF.
Average speed is 3 kb/s, actual is 4169 kb/s.
Total scanning time by now is about 1 hour IIRC.

Just looking for an idea how long it will scan for - i.e. several hours, days, weeks or months?

At an average of 3 kb/s the outlook should be 578 days, or year and a half. Does it really take that long to repair a drive?

The scan pattern is very uniform, it looks like this:

xRxR5_______xRxR5_______xRxR5_______xRxR5_______xRxR5_______xRxR5_
______xRxR5_______xRxR5_______xRxR5_______xRxR5_______xRxR5_______
xRxR5_______xRxR5_______xRxR5_______xRxR5_______xRxR5_______xRxR5_
______xRxR5_______xRxR5_______xRxR5

where R is for blue remap block, _ is for <3ms and 5 is for <5ms blocks. Does it mean head crash and that drive is garbage?

At this point there's really no reason to keep the drive unless you have some use for a known-bad HD. Regardless of how long the scan takes to finish it will not be "repaired" at the end.

Bin the drive, it will only get worse with time.

You are going about this wrong. You need to put the drive in a freezer for 48 hours, whack it with a hammer 8 times and then run SpinRite. If you aren't happy with the result, give it a second go with HDDRegen and throw it into your oven at 475 for another 24 hours. When finished, throw the drive in the garbage and buy a new one.

Seriously, though. A drive with one or two bad sectors might be worth a sector remap, but not without knowing why the two sectors are bad. A remap may not buy you much time, as the drive may completely fail in a matter days, hours or minutes. If you are playing, have fun. If you want to use the drive, you definitely need to buy a new one.

Bin it? Heck no, it's under warranty from WD.

Great, that's the ticket to a fresh start.
