Hard disk problem

Hard disk problem

Post by Geoff Johnsto » Tue, 20 Oct 1998 04:00:00



I bought an 8.45GB EIDE UDMA hard disk (IBM DHEA-38451) and connected it to
the primary slave channel, thus:
hda: 3.2GB Western Digital Caviar
hdb: 8.45GB IBM
hdc: IDE CD-ROM drive
hdd: ATAPI ZIP drive

I created a 2GB DOS (FAT16) partition (yes I know the cluster size is huge)
and 7 logical partitions, all ext2. All worked OK for a while, ran e2fsck when
demanded on hdb5, 6 and 8. Then suddenly hdb6 wouldn't mount 'cos magic
number was wrong. Run mke2fs, lose all data.

Yesterday, lost hdb6 - hdb12 (i.e. hdb5 still there but it's the only logical
partition that the OS and Linux FDisk can see)!!

Questions:
1. Do ext2 partitions disappear if not used for (e.g.) four weeks? I know
it's a very silly question but I need to know before I speak to the supplier)

2. Is there something wrong with the partition sector on the disk (i.e.
physically wrong)?

Thanks,

Can you recall what you did right before it "disappeared" in the 4
weeks? This might be caused in DOS/Windows box cuz the duo are famous
at overwriting.

 
 
 

1. Help! Hard Disk Problem!

My hard disk is a Maxtor 9043D2 IDE ATAPI. I am using Mandrake 8.0 and
it keeps on showing:

hda: timeout waiting for DMA
ide_dmaproc: chipset supported ide_dma)timeout func only: 14
hda: irq timeout: status=0x58 { DriveReady SeekComplete DataRequest }

Can anyone tell me what is wrong? How should I fix it?

Thanks a lot!
