Hi!

I have a problem with hdd:

ad4s1f: hard error reading fsbn 86162431 of 40472032-40472063 (ad4s1 bn
86162431; cn 5363 tn 92 sn 40)ad4s1f: hard error readi

This happened sometimes after the boot.

Booting procedure returns normal status:
ad4: 29314MB <IBM-DTLA-307030> [59560/16/63] at ata2-master UDMA100


Disk is on Promise ATA controller:
atapci1: <Promise ATA100 controller> port
0x7800-0x783f,0x8000-0x8003,0x8400-0x8407,0x8800-0x8803,0x9000-0x9007 mem
0xe4000000-0xe401ffff irq 15 at device 17.0 on pci0

I also have VIA IDE controller:
atapci0: <VIA 82C686 ATA66 controller> port 0xb800-0xb80f at device 4.1 on
pci0

And I have a CD-ROM on it:
acd0: CDROM <ATAPI CD-ROM DRIVE 50X MAXIMUM> at ata0-master using PIO4

I use 4.5 release:
FreeBSD triton.irb.hr 4.5-RELEASE FreeBSD 4.5-RELEASE #2: Wed Mar  6
16:15:36 CET 2002     root@triton.irb.hr:/usr/src/sys/compile/TRITON-01
i386

Can anyone point me out where the problem might be? Maybe in hdd itself?


Thanks!
