Disk /dev/hdb doesn't contain a valid partition table
 
Greetings!

I have a Linux Workstation running Red Hat Enterprise Linux ES (2.4.21-37.ELsmp). The system was working perfectly before until I moved it to a new place!!! Prior to the move, I had shut it down and it did so normally; I then moved it to a new location (I believe I took care not to be jerky while moving) and then plugged it in -- I initially got a "Fsck: Unexpected Inconsistency" error. I went through the recommended fsck routine and now I get the following error:

fsck.ext3: Attempt to read blcok from filesystem resulted in short read Could this bea zero-length partition?
while trying to open /dev/vg01/lv_data

[FAILED]...


I opened up the box to make sure the IDE cables to the HDDs are proper and then I rebooted the m/c. After checking a number of posts and doing various checks, these are what I found:

1. dmesg | less

hda: ST380011A, ATA DISK drive

sector=33162
end_request: I/O error, dev 03:40 (hdb), sector 33162

Is there a way to recover my lost data? Any help is greatly appreciated.

I don't have this knowledge and i hope you'll get some help over here.
Search these forums because they are already filled with answers.
I just want to say that maxtor hd are the less reliable ever. I have another proof today. I use only seagate since 1994 and i never had any problem. Hope this opinion will save your datas in the future.
