i have a seagate barracuda ata 4 as master(40 gb), but i decided to put a second.(seagate 20gb) ..but there was a jumper problem, both had the jumpers as masters (i forgot) so i restarted the computer for an auto detect for the second drive in the bios.. i donw know, but the hard drive did a strange sound.. i unplugged the second, letting the things as yesterday.. but.. there was no hard drive detection (in the bios) and a messagge of a missing operating system . i used diskwizard for seagate instalation, it told me that there was no hard drive (i plugged it in every single way) i used a program like fdisk to check (as last resourse) this program detected my hard dirve ,it told me that there was two partitions in my hard drive Q and U. one had 8 mb. and the other had 22003 mb. in a unknow filesystem, so i tried to delete these partitions but it told me that it canT do that, so there was another option to analyce/check drive, and it had a information problem.. it says that my hard drive had 5698 cyl. 58 hds 63 sec and 982356 lba but..my hard drive information is model st340016a 16,383 cyl 16 hds 63 sec 78,156,288 lba and this software had the choice to replace this information (experts option)but this said that i have to analyce the drive first, well. then i did hit enter to analize, and it says that the drive have a geometric problem and stopped analyzing(i don´t know if this was caused due to electric shok or problems). so i want to know what should i do.. and what king of software to do it..

are you sure hard drive jumpers are in correct position. some hard drives have a jumper position where it reduces the capacity of the hard drive so that older computers with limited hard drive size in the BIOS can use them. It is fine for a new format of hard drive but probably would cause confusion for a hard drive that already had loads of stuff on it.

Yes, go over the plugging instructions again. Also, in depends on how you look at the drive. Holding the drive upside down can really mess things up. Do yourself a favor BACKUP! Sorry, I do not check for private messages

"Yes, go over the plugging instructions again. Also, in depends on how you look at the drive. Holding the drive upside down can really mess things up." Unless...........You stand on your head.LOL

some times the jumper diagram is on the basis that you are holding the drive upside down (that is - the lable face down to floor)
