Hi, My name is Dave. Have you been able to solve your problem dated 04/17/02 see: https://listman.redhat.com/pipermail/ataraid-list/2002-April/000681.html I am having intermittent system hangs with this drive and have some of the same geometry questions you do. I am repairing a 4 year old system for a customer who has had this hanging problem from the start, yet didn't return it for service under warn.. Now the problem is beginning to occur more frequently and wants to see if I can fix it. Write if you need more info, working on it for days, can't make it occur although it appears sometimes to have to do with the disk drive. Here is what it should be: http://www.seagate.com/support/disc/ata/st34321a.html SEAGATE Support: ST34321A Illustrated Configuration Capacity: 4.3 GB Speed: 5400 rpm Seek time: 11.5 ms Cylinders: 555 Heads: 240 Sectors: 63 SeaFAX#: 343212 and what I see from BIOS As BIOS Setup: LBA, UDMA, 4303 MB HARD DISKS Pri Mstr TYPE User SIZE 4302 CLYS 523 HEAD 255 PRECOMP 0 LANDZ 8893 SECTOR 63 MODE LBA What ever happened, I'll be waiting to hear Thanks in Advance B.
