Seagate ST3320620AS very slow copy

[slack]

Hi,

I have one Seagate hdd which is working very slow , after every copied LBA it gives this lines

CE Log ErrCode=43 LBA=2501220c Type=4 Remove from Pending 2501220c
AT Er 00 Nwt Er 43 RdWr 1f23d.00.0005
ATA St d0 Er 00 Op 22 e, 159b3ff5,0163 0163 0000
Niwot: 9ff79ff7 b8 9ff79ff7.3.acd 0000 005f 0000 1000
DiskAccess ReadSector EC=43 at 01f23d.00.0005

It copy 1 LBA in 5 seconds, if I try to copy with Read Ignore CRC it copy ~100 LBA in 2,3 second but is still very slow transfer rate.

If i do one Logical Scan it is working normally but when I try to copy..... begin to click and give that log in termminal.

What can be the problem ?

Thanks.

Dear ionut_bit,

It's a head problem. Head Swap will help.
So the donor drive must have the same Config, Site Code, Capacity and compartible heads map.

you can make sure by checking head in terminal
will tell you which head was dead....

Its adding sectors to the pending list, maybe could be stopped or bypased to read sectors, thats possible with UDMA no?

Lots of error type 43 usually means dead head or heads in my experience. Also, head test I do not think is totally accurate. I would replace heads and write the results here.

OK... Please tell the whole progress.....
