I have here several SCSI drives. I like to connect them to a PC. What is required in the way of connectors to IDE or SATA?

Re: SCSI drives
A SCSI card. Preferably Adaptec. -
Re: SCSI drives
You're not going to find anything to convert them to IDE or SATA. As seanc said, pick up a PCI SCSI card.
Or, if they're older drives, toss 'em. SATA is faster than the old clunker SCSI drives anyway.Ludicrous gibs!

Re: SCSI drives
You will need an Adaptec 29160 or 39160 card (fits in PCI slot on your mobo) and a 68-pin SCSI cable with terminator .
If the SCSI drives come from a later model server, they are probably 80-pin SCA, and you will need an adapter to convert the 80-in to 68-pin. ( 80-pin drives hot-plug directly to a backplane without a cable)
I do this all the time as I have a large number of SCSI drives on hand.
If the SCSI drives you have are 50-pin forget it. Also if the drive has "FC" on it, it's Fibre Channel. Forget that too.
SCSI drives are fast, especially the 15K rpm ones.Comment

Re: SCSI drives
There's also more to SCSI than setting Master or Slave - you have to jumper each drive to a unique address (from 0 to 15 for 68-pin SCSI, with 7 usually allocated to the SCSI controller itself)
If the SCSI cable does not have a terminator on its end, make sure only the final device on each SCSI connection has Termination set On - all other devices must be Off
Instead of Adaptec controllers, I prefer LSI, previously called Symbios, originally called NCR
However, Adaptec documentation is perhaps more SCSI newbie friendlybetter to keep quiet and be thought a fool, than to open your mouth and remove all doubtComment

Re: SCSI drives
This is one of the drives.They came out of a govt. server so they wont have done much work!

Re: SCSI drives
If I'm reading that right.... 4.3gb 10k? I wouldn't bother.Ludicrous gibs!

Re: SCSI drives
I agree 4.3GB is too small to be useful. It takes 3GB or so to load an operating system. If it is a 68-pin drive you could chain several together on the cable, but even still, too small.
Show us the end where the cable connects. Also does it say on the Drive what the speed is? Some are 7200, some are 10,000 and some are 15,000 RPM. 7200 is not desirable.
If it's an 80-pin SCA drive you have to use an adapter, and are recommended to have no more than 2 drives per cable.
Also the older drives can run hot and be whiny.
Remember these things run 24/7 for up to 7 years.
The Mean Time Between Failures (MTBF) of SCSI is 1.5 million hours (yes).
That's why they cost more and that's why they are kept in service so long.
At the end of their lives they can be "tired".
Compaq does not build their own drives, that one looks like a Seagate or Fujitsu. I prefer Fujitsu - cooler and quieter. Maxtor and IBM (later Hitachi)
also made SCSI drives.Comment

Re: SCSI drives
4.3, 10k (10000 rpm)
maybe with a HBA using linux raid 5 you can get some decent space if you put like 7 of these in, but that decent space is sill very small (25G for 7/w raid 5)Cap Datasheet Depot: http://www.paullinebarger.net/DS/

Re: SCSI drives
Think of all the power they consume too. Even the 36gb drives are too small. I'd wait till you get some 73gbs. They are very common.
Get a cheap jbod (hp disk system, etc) and a scsi card. These drives are very loud so even for free they might not be a good idea when a 1TB ide drive is < $70.
I have a box of FC drives of a decent size but I can't really do much with them as everything to do with them is expensive. Can't sell them because they came out of customer's servers and probably have data on them.Comment

Re: SCSI drives
Make sure that you use the right SCSI terminator (SE or LVD).
Serial Attached SCSI (SAS) dispenses with terminators.My first choice in quality Japanese electrolytics is Nippon Chemi-Con, which has been in business since 1931... the quality of electronics is dependent on the quality of the electrolytics.Comment

Re: SCSI drives
Raid 0 a pair of those for 8.6G just for the OS, Raid 0 2 more for a 8.6G virtual memory swap drive, and JBOD the rest as your data storage and your set.Comment

Re: SCSI drives
Sas is the way to go now if you are buying.Comment

Re: SCSI drives
Knowing how many you have exactly would help but just guessing if it 6 or more then Raid 0 a pair of those for 8.6G just for the OS, Raid 0 2 more for a 8.6G virtual memory swap drive, and JBOD the rest as your data storage and your set.
Considering they were free its crazy to say it would be cheaper to buy the other drives (SAS) etc the others mention. Speed wise and $ wise they are plenty fast enough setup as I suggested and your investment will be much less than all the other suggestions.Comment

Re: SCSI drives
Not true, you can buy SCSI to Sata converters, they arn't cheap so this wouldn't be a good choice for these smaller drives.
Older 10K SCSI are still faster than 90% of the SATA drives now made (just because its a Sata drive doesn't mean its doing 1.5g or 3g transfers) the older SCSI drives spinning at 10k RPM and small like these 4.6G drives are screaming fast in a raid and will own most any SATA drives in benchmarks on the proper controller.
In fact 2 of these small 10k SCSI drives in raid 0 on a 39320 controller bench faster than 2 WD Sata 10k raptors, I know this for a fact as I have both setups.Comment

Re: SCSI drives
SCSI/SAS/FC have higher sustained rates than consumer oriented things like SATA. Drives are more durable too. The 1.5/3gb rate is mostly burst.Comment

Hi,
I have the above mentioned bord after repair, which was related to a lot of missing smd devices on the back of the board.
There were almost 20 devices missing, caps, resistors and some diodes/mosfets.
The board is generally working now, all PCIe ports are working, Windows installs normally.
However I have a problem with SATA ports 4-7 (the board has 8 SATA ports) - disks are not beeing recognized by the BIOS neither by Windows (which is usually normal in case BIOS does not recognize them).
The SATA 4-7 driver network is quite simple chipset<->buffers/drivers<->SATA... -
Like the title says, I have a Pegatron M2N78-LA (HP P/N: 513430-002) motherboard out of an HP Pavilion PC. The motherboard hard-locks during POST when it gets to the part of trying to detect the SATA devices *only* if there is a SATA device (be it HDD or optical drive) connected to any of the SATA ports. I cannot enter BIOS or do anything when this occurs. Pressing Ctrl+Alt+Del cannot restart the system either. In fact, the keyboard locks up too (Num Lock status LED cannot be toggled anymore.). However, if I disconnect everything from the motherboard's SATA ports, the motherboard can POST successfully...

Oh wow.
As in the other thread I was trying to revive/re-bootstrap an old Apple IIe and wasn't successful reading or writing any disk. Both drives behave similarly.
Then I was wondering, what about my PC floppy drives? I have a HH 5¼" HD drive and a combo 5¼+3½ drive. I tried formatting the disk that wouldn't work in the Apple and it didn't work in the PC either!
Then I tried a HD 5.25 disk ... it won't even touch the disk either! Just like the Apple DD disk, "Not Ready!"
Weird. Seems the PC drive is having trouble clamping... -
Need help to solve some problems with this laptop.
After working in bed with it one night and heating up too much (probably the cause of this problems) the sata HDD OS windows froze
After restart the original Sata HDD was not recognized anymore (but works fine in other laptops or PCs)
Tried connecting other good Sata 2.5 HDDs but not one is working in this laptop anymore (not the original nor others)
Before this had happened I observed some other problems:
When I tried replacing original mecanical HDD with a SSD HDD could not get them...
