After Partitioning a Drive: WARNING - WRITE_DMA UDMA ICRC error (retrying request)

[Mark Kane]

Hi everyone. I have searched the lists and Google about this, but none 
of the things I find seem to be my exact problem.

I have an 80GB Maxtor IDE hard drive that was in NTFS yesterday. Last 
night, I copied all 75GB of data off that drive to another drive in the 
system. It took a while, but didn't give any errors.

Today, I go to use sysinstall to fdisk and disklabel the drive to make 
it UFS for use with FreeBSD. That goes OK and it's now mounted fine. I 
go to copy the data back from the backups I made last night, and 
immediately I get tons of warnings like this:

ad1: WARNING - WRITE_DMA UDMA ICRC error (retrying request) LBA=3205439
ad1: WARNING - WRITE_DMA UDMA ICRC error (retrying request) LBA=3206591
ad1: WARNING - WRITE_DMA UDMA ICRC error (retrying request) LBA=3208767
ad1: WARNING - WRITE_DMA UDMA ICRC error (retrying request) LBA=3210047
ad1: WARNING - WRITE_DMA UDMA ICRC error (retrying request) LBA=3214655

ad1: WARNING - WRITE_DMA UDMA ICRC error (retrying request) LBA=4163583
ad1: WARNING - WRITE_DMA UDMA ICRC error (retrying request) LBA=4164479

Most of the things I see from searching online point to faulty IDE 
cables, but I swapped the cables a month or so ago. Also, the drive that 
I copied all this data to last night (a 160GB Maxtor) is on the same IDE 
cable as this one with no errors.

I have 3 more drives to backup and "convert" from NTFS to UFS after 
this, so if anyone has any ideas to help me get on my way, that would be 
excellent.

Thanks very much in advance!
